Compound fertilizer for stress-resisting yield increase of strawberries and preparation method of compound fertilizer

Abstract

The invention discloses a compound fertilizer for stress-resisting yield increase of strawberries. The compound fertilizer is prepared from the following raw materials in parts by weight: 20-30 parts of moisture-removing soil, 6-8 parts of glauconite powder, 40-60 parts of dry chicken manure, 3-4 parts of EM fungicide, 2-3 parts of pimacol, 4-6 parts of zinc sulfate, 6-8 parts of ferrous sulfate, 14-18 parts of silkworm excrement, 6-8 parts of calcium superphosphate, 12-16 parts of saw dust, 8-10 parts of lobster powder, 20-26 parts of sweet potato powder, 9-13 parts of soybean meal, 5-6 parts of crotalaria juncea, 5-6 parts of soil modifier and a proper amount of water. The fertilizer disclosed by the invention can be used for providing a lot of required materials for growth of strawberries by virtue of adding inorganic quick-acting fertilizers such as zinc sulfate, ferrous sulfate and calcium superphosphate, meanwhile, natural organic fertilizers such as chicken manure and silkworm excrement which are further added are decomposed to nutrients which can be absorbed by strawberries under the effect of the EM fungicide, and the beneficial microbial ecosystem in soil is improved, so that the development of strawberries is promoted. By adding pimacol, the resistance of strawberries to drought and plant diseases and insect pests is enhanced, the survival rate of strawberries is improved, and the purposes of low input and high yield are achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound fertilizer for increasing strawberry production against stress and a preparation method thereof. Background technique [0002] Strawberry is a perennial herb and a small berry with high economic value. Its fruit is soft and juicy, sweet and sour, delicious, rich in nutrition, beautiful in appearance and rich in aroma. Therefore, it is favored in domestic and foreign markets and is known as the "Queen of Fruits". ". At the same time, there is a strong demand for strawberry fresh fruit consumption in major large and medium-sized cities in China, and fertilizers are an important tool to improve the quality and output of strawberries. At present, there are no common special fertilizers for strawberries on the market, and the traditional inorganic fertilizers cannot fully meet the ratio of various nutrient requirements of strawberries, and will also cause soil compacti...

AI Technical Summary

Problems solved by technology

At present, there are no common special fertilizers for strawberries on the market, and traditional inorganic fertilizers cannot fully meet the ratio of various nutrient requirements of strawberries, and will also cause soil compaction, soil fertility decline, ecological damage, environmental pollution and agricultural pollution. A series of problems such as the decline in the quality of by-products do not conform to the principle of sustainable agricultural development
