[0002] At present, chemical fertilizers such as nitrogen fertilizer, phosphate fertilizer, and potash fertilizer in traditional agricultural production can no longer meet the needs of modern agricultural development. Green, multi-effect, and pollution-free functional biological fertilizers are increasingly attracting the attention of agricultural authorities and practitioners, such as microbial fertilizers, amino acid fertilizers, and humic acid fertilizers. These biological fertilizer products can not only provide plants with rich organic nutrition and improve crop resistance, but also quickly supplement soil flora and stimulate soil activity; they are especially suitable for preparing various types of water-soluble fertilizers for modern efficient facility agriculture, which are convenient for drip irrigation, flushing, and foliar spraying, and the demand is constantly increasing. However, the existing products such as microbial fertilizers, amino acid fertilizers, and humic acid fertilizers have long cycles and small outputs, which cannot meet the huge demand, resulting in the generally high prices of functional biological fertilizers.

[0050] Application Example 1-23 The plant cell nutrients prepared in Example 1-23 were diluted 500 times with water to prepare foliar fertilizer.

[0051] Application Comparative Examples 1-4 The plant cell nutrients prepared in Comparative Examples 1-4 were diluted 500 times with water to prepare foliar fertilizer.

[0052] Performance Testing 1. For the plant cell nutrients in Examples 1-23 and Comparative Examples 1-4, the fermentation filtrate was taken for testing on the 15th, 20th and 30th days of fermentation. The test indicators were determined according to the physical and chemical indicators of plant enzymes for planting in "Plant Enzymes" (QB / T 5323-2018), including general physical and chemical indicators and characteristic physical and chemical indicators. The test results are shown in Tables 2 and 3.

[0053] 2. The prepared foliar fertilizer is used in a tomato plantation, and 10 tomato seedlings are applied to each group of examples or comparative examples. When the tomato seedlings are 15 days old, the nutrient solution prepared in Example 1 is diluted 50 times with water for the first spraying. The weight ratio of the foliar fertilizer to the tomato seedlings is 1:8. Thereafter, the foliar fertilizer is sprayed once every 10 days during the entire growth cycle, and is sprayed on the front and back sides of the leaves and the surface of the stems and the ground around the stems until the tomato fruits are ripe and harvested. A blank control group is set up, and the tomato seedlings in the blank control group are fully fertilized when they are planted. Conventional topdressing and manual weeding combined with biological drug pest management are carried out according to the growth conditions in the later growth.

[0054] During the entire growth period, the average plant height, average stem diameter and average number of fruits per plant of tomatoes were measured regularly, and the average weight of a single fruit was weighed after the tomatoes matured. The measurement results are shown in Tables 4 and 5.

[0055] 3. The inhibitory effect of plant cell nutrients on fungal diseases of crops was tested by the steel ring diffusion assay. The spores and hyphae of pathogenic fungi in a test tube were scraped off with 5 ml of sterile water, poured into 100 ml of potato culture medium cooled to below 45°C and shaken well. 12.5 ml of bacterial culture medium was added to each culture dish, and a stainless steel ring was placed in it after solidification. The diluted plant cell nutrients were added, and the size of the inhibition zone was measured according to the growth rate of different bacteria. The test results are shown in Table 6.

[0056] Table 2 By analyzing the data in Table 2 and comparing Examples 1-9 with Comparative Examples 1-4, it can be seen that adding animal tissue waste and molasses to the prepared plant cell nutrients is conducive to the accumulation of organic matter in the plant cell nutrients, and the organic matter content is high, which can be applied in foliar fertilizer to give crops more sufficient growth nutrients; in addition, its protease activity is also high, which is conducive to decomposing macromolecular organic matter into amino acids, polypeptides, etc. that are easily absorbed by plants. At the same time, the organic acid content in the comparative example is relatively large, so that the prepared plant cell nutrients are acidic, which is not conducive to the absorption of plant cell nutrients by plant leaves.

[0057] Table 3 By analyzing the data in Table 3 and comparing Example 2 with Examples 10-23, it can be seen that the meat-bone ratio in the animal tissue waste and the total content of cellulose, hemicellulose and lignin in the organic fiber raw material have a significant effect on the organic matter content in the prepared plant cell nutrients. Only when the weight ratio of meat to bone in the animal tissue waste is 7-15:1 and the total content of cellulose, hemicellulose and lignin in the organic fiber raw material is 45-65%, the organic matter content in the prepared plant cell nutrients is higher; after adding aromatic plants, the protease activity is significantly increased during the fermentation process, and the organic acid content is also significantly reduced, especially when the aromatic plant raw material is composed of mint, garlic, perilla and cornflower in a mass ratio of 10:8:7:5, the organic acid content is significantly reduced; during aerobic fermentation, the organic acid in the plant cell nutrients can be significantly reduced by controlling the oxygen content in the container; by controlling the water content of the fermentation substrate of anaerobic fermentation to 46-65%, the fermentation bacteria can promote the decomposition of the fermentation substrate and release more easily absorbable organic matter.
