Special fertilizer capable of improving soil structure for lotus root

Abstract

The invention discloses special fertilizer capable of improving a soil structure for lotus root. The special fertilizer is prepared from the following raw materials in parts by weight: 60 to 80 partsof ammonium nitrate, 50 to 60 parts of potassium polyphosphate, 20 to 40 parts of potassium chloride, 10 to 20 parts of ammonium phosphate, 15 to 25 parts of trace element fertilizer, 0.4 to 0.8 partof sodium naphthalene acetate, 4 to 8 parts of compound protein, 20 to 30 parts of diatomite, 6 to 10 parts of talcum powder, 8 to 14 parts of attapulgite, 20 to 30 parts of a coating agent and 90 to100 parts of water. The compound protein is prepared by adopting the following process: uniformly mixing house-flies larva protein, peanut protein and a formaldehyde solution; adding a sodium hydroxide solution for stirring; adding chitosan and melamine for continuously stirring, raising the temperature, stirring and cooling to obtain the compound protein. The special fertilizer disclosed by the invention can be used for adsorbing metal ions in the soil, contains various nutritional ingredients needed for the growth of the lotus root as well as has a good slow release effect and obvious effects of promoting roots and strengthening seedlings, activating the soil, increasing the yield and improving the quality; the production of the lotus root is greatly increased.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special lotus root fertilizer for improving soil structure. Background technique [0002] Because the lotus root planting process often needs to maintain different water levels, the water in the lotus pond is often retracted and released, causing many nutrients to dissolve in the water and lose with the flow of water. On the one hand, it is a great waste, and at the same time, it causes serious water damage In order to solve the problem of soil pollution, when planting lotus root, the suitable planting environment should be a thin mud rich in organic matter, good soil circulation performance, sufficient nutrients and easy absorption by the root system, and the soil should not be hardened. [0003] Nutrients are easy to lose and frequent fertilization is required, and the absorption effect of lotus root is limited, resulting in the increase of inorganic ions in the soil, res...

AI Technical Summary

Problems solved by technology

[0003] Nutrients are easy to lose and frequent fertilization is required, and the absorption effect of lotus root is limited, which leads to the increase of inorganic ions in the soil, resulting in soil compaction, which is not conducive to the growth of lotus root. The soil is very deep, which will not only affect the artificial harvest, but also the compacted soil is not conducive to the absorption of nutrients by the root system, resulting in a reduction in lotus root production
