Description
Technical Field
The invention relates to the technical field of ecological corn fertilizers, in particular to a water-retaining and fertilizer-retaining molasses ecological corn fertilizer.
Background
The cultivation history of corn in China is about 470 years. At present, the sowing area of China is about 3 hundred million mu, which is second to rice and wheat, third to grain crops and second to America all over the world. It is widely planted in tropical and temperate regions of the world. The fertilizer is mainly farmyard manure and is auxiliary. In China, most corns are planted in hilly areas, the soil layer is thin, the fertility is low, farmyard manure is mainly organic fertilizer, the fertilizer contains rich nutrient components, the soil can be improved, the land utilization can be improved, and the fertilizer efficiency is longer. The fertilizer is a quick-acting fertilizer, and although the fertilizer also contains nutrient elements required by corn, the nutrient components are single compared with the nutrient components of farmyard manure. Meanwhile, other components are remained in the fertilizer in the application process, which is not beneficial to the growth of corn and the improvement of soil fertility. For foliar fertilizers, a plurality of domestic markets appear in recent years, most of the foliar fertilizers are hormones, and the second is a mixed type. The hormone is added with an artificial chemically synthesized plant growth regulator, has the functions of dividing plant cells and stimulating the growth of plants, is beneficial to certain plants, but cannot be used as a broad-spectrum type, is not suitable for young crops and is not suitable for perennial crops and seed-reserving crops. The mixed type is mostly the mixture of inorganic or organic compounds, certain nutrient components are added, the yield increasing effect is achieved on crops, but the disadvantages are that: most products have stink or pungent smell, the yield increasing effect is not obvious, the performance is not stable enough, the fertilizer efficiency is not strong enough, the using concentration is harmful to crops, the power for eliminating soil hardening is insufficient, the surfaces of attached plants are not durable after being sprayed, the plants are easy to evaporate or lose, and the disease resistance is not strong. And at present, the pollution is serious, heavy metal ions which can effectively prevent plants from absorbing the soil do not exist, and the fertilizer has single benefit and is not diversified.
Chinese patent document "a corn fertilizer (patent No. CN 105859490A)" discloses a corn fertilizer and a preparation method thereof, wherein the corn fertilizer comprises the following components in parts by weight: 40-45 parts of urea, 15-25 parts of humic acid, 15-25 parts of ammonium dihydrogen phosphate, 8-12 parts of potassium hydroxide, 7 parts of vinasse, 4 parts of zinc sulfate, 3-5 parts of sodium alginate solution, 0.5-0.7 part of yeast chromium and 4 parts of urease inhibitor.
In order to solve the general low-yield phenomenon caused by drought in corn planting areas in south China at present, a water-retaining and fertilizer-retaining molasses ecological corn fertilizer is provided.

Analysis of Experimental data
TABLE 1 maize growth traits
The investigation time of the growth traits of the corns is 6 months and 17 days, the corns stop pulling up, the thickness of the corns is basically kept consistent, and the number of the buds is changed slightly. As can be seen from Table 1, the plant height was 229.19cm at the highest, which is a control group, 205.60cm at the lowest, which is example 5; the diameter of the ground is 23.7 at the thickest, is example 2, and 23.07 at the thinnest, is example 1, and the other treatment diameters are not different, the number of bracts is 1.8 at the most, is example 1, and is 1.26 at the least, is example 2.
Table 2 shows the corn yield table
In the experiment, the fertilizer dosage of the control group 1 is 1.84 times of the treatment dosage of the design formula examples 1, 2, 3 and 4, the dosage of the example 5 is 1.75 times of the dosage of the design formula examples 1, 2, 3 and 4, and the cost of the two fertilizers is 20.5 yuan/90 m2, namely 151.9 yuan/mu.
The corn harvesting time was 8 months and 10 days, the cell average weight algorithm, the yield was calculated by converting the cell area to 90m2 and 667m2, and 422.62 is (57.03/90) × 667 for the control group 1 treatment. As can be seen from Table 2, the yields of control 1, example 2, example 3, example 4 and example 5 were 422.62 kg/mu, 553.19 kg/mu, 576.21 kg/mu, 387.78 kg/mu, 442.81 kg/mu and 272.54 kg/mu, respectively, at the same cost, the best treatment was example 2, the yield increased by 113.01% in comparative example 5 and the yield increased by 36.3% in comparative control 1.
The processing yield improvement difference of the example 1 and the example 2 is small compared with the processing yield improvement of the water-retaining agent, the discharge error causes and the content of the water-retaining agent is not large, and the water-retaining agent is expensive.
The results of the anova showed that the treatment in example 2 was 15-6-9, the organic matter was 15%, and the difference between the water retention agent and other treatments was significant, which was the optimal treatment. The design formulas of example 1, example 3 and example 4 are significantly different from example 5, but are not significantly different from the control group 1. The formula product designed in the time can be divided into three gradients, wherein the first gradient is 12-8-9, the second gradient is 12-8-5 and 12-8-15, and the third gradient is 22-0-5.
In addition, on the premise of equal quality, 12-8-5 and 12-8-15 are compared to find that the dosage of 12-8-5 is 1.84 times of the dosage of 12-8-15, namely the dosage is high in nitrogen and phosphorus but low in potassium, and the yield is not obviously different from that of 12-8-15, which indicates that the corn yield cannot be improved to a certain extent even if the corn is high in potassium.
To sum up the above
In the experiment, the optimal formula is 15-6-9 of the formula in example 1, 15% of organic matters are adopted, and the water-retaining agent is not required to be added in the subsequent production.
The formulation is able to achieve higher yields than other products when the initial design requirements of the experiment are met, i.e. when half of the amount of other products are applied.

After the natto bacillus sugar cane molasses alcohol waste liquid is subjected to drought treatment for 5 days, the average humidity of soil in a pot is 92%, plants in the pot are still green, and leaves are stiff; after 7 days of treatment, the average humidity of soil in the pot is 63%, the leaves of the plants in the pot are still dark green, but the leaves at the edges are slightly dehydrated and have softer touch. After the fish protein is subjected to drought treatment for 5 days, the soil humidity in the pot is 55%, the edges of the plants in the pot are dehydrated and yellowed, the touch feeling is soft and thin, and heart leaves still keep green; after 7 days of fish protein treatment, the humidity of soil in the pot is 38%, the leaves at the edge of the plants in the pot lose water seriously, and the leaves lose water when being dried up by touch, and only the heart leaves still keep dark green. After the sugar cane molasses waste liquid is treated by drought for 5 days, the soil humidity in the pot is 80%, the plant leaves in the pot are still green, the touch feeling of the edge leaves is slightly soft, the heart leaves are still very stiff, after the sugar cane molasses waste liquid is treated by drought for 7 days, the soil humidity in the pot is 51%, the edge leaves are soft, the touch feeling is single and soft, and the heart leaves are still green.
