Description

Method for realizing ecological cycle by combining sugarcane field planting and breeding
Technical Field
The invention belongs to the technical field of modern agricultural planting and breeding combination, and particularly relates to a method for realizing ecological cycle by combining sugarcane field planting and breeding.
Background
The sugarcane industry is one of the important dominant industries in Guangxi, and plays a key role in balancing the supply and demand of sugar in China. However, due to the high concentration of sugarcane planting, the output of the sugarcane field is far less than the demand of the market for the sugarcane, and part of the land is continuously cultivated all the year round, so that the fertility of the soil is reduced, and the diseases and the pests are serious. The problems of single variety, degeneration of the seed nature, low yield and the like of the sugarcane still remain the neck bottle problem which influences the development of the sucrose industry. At present, in the production of sugarcane, farmland is only used for planting sugarcane, a three-dimensional planting ecological cycle mode is not well developed, the prevention and the control of plant diseases and insect pests are simply carried out by chemical prevention and control, the use of a large number of chemical products leads the biological chain in the field to be damaged, the damage degree of the plant diseases and insect pests is increased, and the sugarcane is not used in the yield and the ecology is damaged. Therefore, the combination of the ecological planting and the ecological planting of the sugarcane field is a production mode which realizes the common development of the planting industry and the breeding industry, improves the utilization rate of the resources of the sugarcane field, protects the ecological environment of the sugarcane field and has huge production potential, social market demand and green development prospect.
The invention patent application CN 105265381A discloses a method for raising chickens under sugarcane, which is to build a chicken farm in a forest land close to a sugarcane field, and when the sugarcane grows to a certain height, the chickens are raised according to a certain density. By reasonably planting the sugarcane and timely stocking chicken flocks with certain density in the sugarcane field, weeds can be removed, pests are eliminated, the production cost of raising the chicken and the sugarcane is reduced, excrement discharged by the chicken flocks can become organic fertilizers of the sugarcane, the application of chemical fertilizers and the organic fertilizers is reduced, and the sugarcane yield is increased. The invention patent CN 105454164B discloses a method for raising chickens among sugarcane rows, which comprises the following steps: arranging a henhouse beside a sugarcane field, and captive breeding chicken seedlings; planting the sugarcane, wherein the row spacing of the sugarcane planting rows is 110-130 cm; collecting chicken manure in a chicken house, mixing the chicken manure with a leavening agent, corn flour or rice bran, and fermenting to obtain fermented chicken manure as a planting fertilizer for sugarcane; in the sugarcane elongation period, after intertillage and heavy accompanying, the capacity of 45-55 chickens per mu in the henhouse is put in the sugarcane rows; after the sugarcane is harvested, the sugarcane leaves are burned, the perennial sugarcane management is carried out, intertillage hilling is carried out in the later tillering stage, and then the planting and breeding cycle of the next round can be continued. By adopting the technical scheme of the invention, the inter-row space of the sugarcane is fully utilized to raise chickens, so that foraging, resting and entertainment places are provided for the chickens, the quality of the local chickens is improved, the soil fertility is also improved, the weeds are inhibited from growing, the root diseases and insect pests are reduced, the ineffective tillering is inhibited, the yield of perennial sugarcane in the next year is increased, and the income of the unit area of the sugarcane field is increased.
Although the two patents disclose an ecological mode combining sugarcane field planting and breeding, the sugarcane-chicken planting and breeding mode is single, the operation of the mode still needs to be maintained only by investing more materials and cost, more wastes are generated, for example, a great amount of sugarcane tail tips are generated during sugarcane harvesting, if the tail tips are not treated, the environment of the sugarcane field is negatively affected by the great amount of sugarcane tail tips, and if the sugarcane tail tips are simply burnt into carbon or smashed and buried into soil, the economic benefit is extremely low. Therefore, the ecological modes disclosed by the two patents are more suitable for small-scale sugarcane fields, and the benefit of the ecological modes for large-scale sugarcane fields is not high; moreover, the mode of sugarcane continuous cropping all the year round also easily causes soil fertility reduction and serious pest and disease damage. Therefore, an ecological circulation system which is lower in cost, better in benefit and suitable for large-scale popularization is urgently needed to be developed, so that the planting and breeding ecological mode of the sugarcane field is more perfect.

1. the method of the invention is adopted to plant the sugarcane and the corn in the sugarcane field, and the pig, the chicken and the hermetia illucens are bred beside the sugarcane field, so that the sugarcane field and the henhouse and the pigsty beside the sugarcane field basically realize self-sufficiency, no waste is generated, no pollution is caused to the environment, the sugarcane, the chicken and the pig have high yield and good quality, the requirements of pollution-free products are met, and the economic benefit is good. The land utilization and the land cultivation are combined, the land capability is protected and improved, the ecological environment pressure is relieved, and a new thought and a new way are provided for promoting the sustainable development of the sugarcane industry.
2. In the invention, the corn is planted in the sugarcane field in the early growth stage of the sugarcane, so that the utilization rate of the land can be improved, the income of a planter can be increased, the positions for planting the sugarcane and the corn are changed after the sugarcane field is renovated every time, the crop rotation of the sugarcane and the corn can be realized to a certain extent, the soil environment is improved, and the total nitrogen, the available phosphorus, the catalase, the urease and the bacteria of the soil are increased. According to the invention, the first generation of sugarcane stems planted by the sugarcane tissue culture seedlings are adopted, and the sugarcane stems are cut into single-bud stem sections or double-bud stem sections to serve as sugarcane seeds of single-plant sugarcanes, so that the healthy sugarcane seedlings have the advantages of high growth speed, strong tillering force, high stem forming rate, high yield, less seed consumption and the like, and the defect of low sugarcane yield caused by degeneration of sugarcane seeds can be reduced by newly planting the healthy sugarcane seedlings in a sugarcane field; the perennial root sugarcane can be used for reseeding, and due to the high growth speed, the influence of the perennial root sugarcane and silage corn on growth can be avoided, and the age limit of the perennial root sugarcane can be prolonged. Because the shading phenomenon is easily formed in the sugarcane field, if the sugarcane or corn seeds are directly planted at the seedling lacking position when seedlings are lacking in the sugarcane field, the growth of the reseeded seedlings is delayed compared with the original newly planted seedlings, and the reseeded seedlings are easily suppressed by the original newly planted seedlings. When newly planted sugarcane or corn is replanted, the sugarcane seedlings or corn seedlings in the outermost rows or columns on the periphery of the sugarcane field are transplanted to the internal seedling shortage position for seedling replenishment, the survival rate of the transplanted sugarcane seedlings and corn seedlings is high, the growth period of the transplanted sugarcane seedlings and corn seedlings is the same as that of the sugarcane seedlings and corn seedlings in the same row, and the problem that the replanted seedlings are pressed by the early-stage newly planted seedlings can be effectively avoided; and around the sugarcane field, because of the shade-free phenomenon, new corn seeds are sown, the growth of the new corn seeds is not influenced by the new seedlings planted in the early stage, only the harvesting period is different from the new corns planted in the early stage, the new corns are directly reserved, the harvested corn is used as the seeds for planting the corn in the second year, and the phenomenon that the corn in the second year is lack of seeds can also be compensated.
3. According to research, the fresh sugarcane tail tips contain 71.9 percent of water and 28.1 percent of dry matter, and the dry matter contains 7.13 percent of crude protein, 3.56 percent of crude fat, 32.45 percent of crude fiber, 51.44 percent of floating nitrogen extract and 5.42 percent of mineral matter. The invention takes fresh sugarcane tail tips or silage prepared from the fresh sugarcane tail tips as pig feed, thereby not only solving the environmental problem caused by the sugarcane tail tips, but also improving the economic benefit caused by the treatment of the sugarcane tail tips. The silage whole-plant corn is rich in nutrition, contains rich protein, mineral elements and vitamins, contains isoflavone substances and multiple growth and reproduction factors, also contains a large amount of crude fibers, and can be added into pig feed by taking the silage whole-plant corn as a feed raw material, so that the feed conversion rate can be obviously improved, the growth performance of pigs can be improved, and the lean meat percentage of pork can be improved. Compared with other feeds, the sugarcane tail tips and the silage whole-plant corn can also greatly reduce the pig raising cost and increase the income of farmers. The silage corns are planted in the sugarcane field in the early growth stage of the sugarcane, the growth period of the silage corns is short, the growth of the sugarcane is not influenced, and the whole silage corns can be harvested in the middle growth stage of the sugarcane to be used as the pig feed so as to make up the phenomenon that the pigs cannot be fed with the feed before the sugarcane is harvested.
4. The silage corn and the sugarcane tail tips are cut short and crushed and then sprayed with microbial liquid for processing to prepare silage, and a plurality of beneficial bacterial groups in the microbial liquid can absorb a large amount of organic nitrogen and inorganic nitrogen which are difficult to utilize by pigs in the silage corn and the sugarcane tail tips so as to convert the organic nitrogen and the inorganic nitrogen into mycoprotein with high nutritional ingredients. The microbial bacteria can produce a large amount of protease, lipase, amylase, cellulolytic enzyme and the like in fermentation, and various enzymes can degrade complex organic matters in the silage corn and the sugarcane tail tips, so that digestion and absorption are promoted, and the utilization rate of the feed is improved. The beneficial bacteria enter intestines and stomach of the pig along with the feed, and can enhance the immunity of the pig and reduce the occurrence of diseases. The fermentation conversion treatment of the sugarcane tail tips or the silage corns by using the microbial bacteria can reduce the content of crude fiber in the sugarcane tail tips or the silage corns by times than that of unfermented fibers and improve the content of crude protein by times than that of unfermented fibers. The silage is sour and fragrant in smell, soft and juicy, good in palatability, rich in nutrition, beneficial to long-term storage, and capable of guaranteeing the requirement of pig feeding on the feed when no fresh feed source exists.
5. The black soldier fly is used for treating the excrement of the pigs and the chickens, and the black soldier fly can efficiently convert organic matters in the excrement into protein components of the black soldier fly, so that excrement accumulation and excrement odor are reduced, houseflies are prevented from breeding, and the excrement is loosened and is more suitable for being used as a fertilizer; the hermetia illucens can also degrade harmful substances and pathogenic bacteria in excrement, so that the excrement is really harmlessly, resourcefully and decreasingly changed, the ecological environment is improved, and the development of low-carbon environment-friendly green agriculture is promoted. Before utilizing black soldier fly to handle the excrement and urine of pig and chicken, utilize EM fungus, broken wall enzyme earlier to handle excrement and urine, the cell wall that can quick enzymolysis organic matter, with excrement and urine fermentation degradation to the degree that does benefit to black soldier fly larva and get the food, need not to add other nutrients, can utilize the nutrient composition synthetic protein and the fat in the excrement and urine fast when black soldier fly inoculates to on excrement and urine. Because the time from the eggs to the pupae of the hermetia illucens is very short, when a large amount of excrement needs to be treated, the excrement is treated by the hermetia illucens alone, and the degradation effect is limited; utilize EM fungus, broken wall enzyme and heisui river horsefly to handle excrement and urine jointly, the effect of handling is better, efficiency is better, and EM fungus, broken wall enzyme exist and both accelerated faecal degradation, also promoted heisui river horsefly's growth. EM bacteria and wall-breaking enzyme exist in excrement all the time, the excrement containing the EM bacteria and the wall-breaking enzyme is prepared into a bio-organic fertilizer, and the EM bacteria and the wall-breaking enzyme enter soil along with the application of the bio-organic fertilizer, so that the number of microorganisms in the soil can be increased, germs can be inhibited, the soil can be improved, and the absorption and utilization of sugarcane and corn on the bio-organic fertilizer can be promoted. The addition of ferrous sulfate in the feces is also beneficial to reducing the odor generated in the feces treatment process. Each generation of hermetia illucens screens partial strong hermetia illucens to lay eggs so as to hatch a new generation of hermetia illucens larvae, enough hermetia illucens are guaranteed to be available for processing continuous excrement, and the screened new generation of hermetia illucens has stronger capacity of processing the excrement and producing protein feed. Adding biological carbon into the excrements treated by the hermetia illucens, wherein the biological carbon can absorb partial moisture, so that the humidity of the excrements is reduced, and then, the mixture of the excrements and the biological carbon is dried under the low-temperature condition, so that the preservation of the biological organic fertilizer is facilitated, and the activities of EM (effective microorganisms) and wall-breaking enzymes are maintained.
