Control group 1000 20.1 26.8~30.8
As can be seen from Table 2, the length of the main root of the plant of the experimental group is increased by 6.7cm compared with that of the average plant of the blank group, the yield per mu is increased by 15.06%, the harvested peppers of the experimental group are full and bright in color, and the harvested peppers of the blank group are in conditions of flat peppers, dark color and the like. The organic fertilizer disclosed by the invention meets the growth requirement of the peppers, can effectively improve the yield and quality, is beneficial to plant root growth, and has a remarkable effect on improving the physical and chemical properties of soil.
Example 3
The special vegetable compound fertilizer is prepared by mixing the following raw materials in parts by weight: 74 parts of horsefly manure (22.94 kg), 49 parts of wormcast (15.19 kg), 24 parts of black soldier fly pupa shell powder (7.44 kg), 5 parts of waste tea seed cake (1.55 kg), 8 parts of wormwood (2.48 kg) and 1.6 parts of premix (0.496 kg).
2. The preparation method comprises the following steps:
(1) Crushing kitchen waste, pulping, three-phase separating the prepared slurry, putting the slurry into a culture container, inoculating a corresponding number of black soldier fly larvae into a culture container A (a cement trench with the length, width and height of 3m, 2m, 0.3 m), inoculating a corresponding number of earthworm seedlings into a culture container B (a trench with the length, width and height of 10m, 0.4m, 0.25 m), and culturing for 10 days and 30 days respectively, wherein the culture container A is used for culturing residual black soldier fly adults and horsefly manure, and the culture container B is used for culturing residual earthworm adults and wormcast. The required horsefly manure and wormcast are obtained through separation.
(2) Air-drying the black soldier fly pupa shell powder, the waste tea seed cake, the wormwood, and grinding the black soldier fly pupa shell powder, the waste tea seed cake and the wormwood into powder when the water content is 30-50%.
(3) Mixing and stirring uniformly the powder of magnesium sulfate monohydrate, ferrous sulfate and boric acid according to the weight ratio of (15-30): (40-70): (1-3) to obtain the premix.
(4) Weighing the horsefly manure, the wormcast, the black soldier fly pupa shell powder, the waste tea seed cake powder, the wormwood powder and the premix according to parts by weight, pouring the mixture into a tank, uniformly mixing, adding an EM microbial inoculum, and further controlling the water content to be below 30% after aging for 10-30 days. And (3) drying and granulating the aged organic fertilizer at low temperature to obtain the special vegetable compound fertilizer, wherein the organic matters account for about 57.7% of the total mass, the humus accounts for about 12.6% of the total mass, and the total nitrogen, the total phosphorus and the total potassium account for about 5.6% of the total mass in the final special vegetable compound fertilizer according to the inspection and calculation result.
Comparative example 3
The same as in example 2 was found to be different in that the fertilizer was obtained by fermenting the same as in example 3 without the black soldier fly pupa shell powder and the spent tea seed cake.
Application example 3
And selecting cucumber planting areas with 3 mu of similar growth conditions in a bottle kiln town in Yuhang areas of Hangzhou city of Zhejiang province, and dividing the areas into a blank group, an experimental group and a control group.
Before 2-3 months of cucumber field planting, applying the special vegetable compound fertilizer of the example 3 as a base fertilizer for each mu of 2000kg; applying 2000 kg/mu of once-fermented pure pig manure organic fertilizer to the blank group; the control group was applied once with 2000 kg/mu of the fertilizer of comparative example 3. Other maintenance conditions and water and fertilizer management are implemented in the same manner according to practical conditions.
Cucumber growth characteristics of each treatment group were examined until cucumber growth matured as shown in table 3 below.
TABLE 3 cucumber growth Properties
Project Cucumber melon length (cm) Cucumber weight (g) Mu yield (kg)
Experimental group 24.4 147.3 7840
Blank group 22.6 140.5 7362
Control group 22.9 142.2 7637
As can be seen from table 3, the average cucumber length and height of the experimental group is increased by 7.96% compared with that of the blank group, the cucumber weight is increased by 4.84%, the cucumber weight per mu is increased by 6.49%, and the cucumber weight per mu is increased by 1.21% compared with that of the control group. The organic fertilizer disclosed by the invention meets the growing requirement of cucumbers and can effectively improve the yield and quality.
According to the embodiment, the special vegetable compound fertilizer provided by the invention can effectively improve the physicochemical property and biological property of soil, enhance the water retention, fertilizer retention and fertilizer supply capability of the soil, provide rich organic matters and comprehensive nutrient elements for crops, play a role in preventing insects and disease, and improve the crop yield and crop quality.
Although the foregoing embodiments have been described in some, but not all, embodiments of the invention, it should be understood that other embodiments may be devised in accordance with the present embodiments without departing from the spirit and scope of the invention.
