The actual application effect of various crops in various regions proves that the monopotassium phosphate has a plurality of excellent effects of remarkably increasing both production and income, improving quantity and optimizing quality, resisting lodging, resisting diseases and insect pests, preventing and treating premature senility and the like, and has the effect of overcoming the insufficient nutrition caused by the reduction of the aging and absorption capacity of the root system in the later growth period of the crops.
Compound sodium nitrophenolate: has the functions of promoting cell protoplasm flow, improving cell activity, accelerating plant growth and development, promoting root growth and seedling strengthening, protecting flower and fruit, bearing fruit and expanding, improving yield, enhancing stress resistance and the like.
Biological agent: the function is as follows: the soil fertility is improved, organic and inorganic nutrients in soil are activated, the fertilizer efficiency is improved, the crop circulation is promoted, the long-acting absorption and utilization are realized, and the roots are increased, the seedlings are strengthened and the fruits are full; improving soil, improving soil aggregate structure, eliminating hardening, improving water and fertilizer retention capacity, and resisting drought, stress, cold and lodging; the soil conditioner can be used continuously, and can improve the micro-ecological environment of soil. Eliminate soil hardening, neutralize pH value and reduce heavy metal and salt and alkali toxicity in soil.
Plant growth regulator: a plant growth regulator is a kind of agricultural chemicals for regulating plant growth and development, including artificially synthesized compound and natural plant hormone extracted from organism. Its existence can influence and effectively regulate and control the growth and development of plants, including a series of plant life processes from cell growth, division, rooting, germination, flowering, fructification, maturation and abscission.
1. Selecting the dosage of the plant growth regulator: the results are shown in Table 1.
TABLE 1
As is clear from Table 1, no plant growth regulator was used, and a disease and insect pest phenomenon occurred. When the using amount is too large, the growth condition of the plants is not obviously improved, so that 10-15 parts of the plant growth regulator is preferably selected comprehensively.
The water-soluble fertilizer of the present invention and a commercially available water-soluble fertilizer were applied to a test field of the same soil in the same amount, respectively, using the commercially available water-soluble fertilizer as a control group.
