Special water-soluble fertilizer for seedlings, and preparation method and application thereof

Abstract

The invention relates to a special water-soluble fertilizer for seedlings, which contains major elements, secondary and minor elements, fulvic acid, rootone, Toosendanin, synergistic phosphorus, surfactant and water, wherein the major elements are metered by N, P2O5 and K2O; the secondary and minor elements are Mg, Fe and Zn; the N, P2O5 and K2O are supplied by urea, potassium dihydrogen phosphate and potassium nitrate; and the Mg, Fe and Zn are supplied by magnesium sulfate, ferrous sulfate heptahydrate and zinc sulfate. The special water-soluble fertilizer for seedlings comprises the major elements, secondary elements, minor elements and beneficial elements required by seedling growth, and can enhance the seedling transplanting survival percent and the leaf chlorophyll content. The special water-soluble fertilizer for seedlings can promote the development of the root system, enhance the quantity and weight of the root system, increase the seedling weight and reduce the pest incidence rate.

Description

technical field

[0001] The invention relates to the field of water-soluble fertilizers, in particular to a special water-soluble fertilizer for seedlings, and more specifically to a special water-soluble fertilizer for seedlings containing azadirachtin, a preparation method and application thereof. Background technique

[0002] With the improvement of people's living standards, the attention to the ecological environment is becoming more and more urgent. It is one of the important measures to improve the quality of the ecological environment and promote the coordinated development of the economy, society and environment by making full use of idle land such as barren hills and slopes, road sides, villages, and communities to carry out landscaping, tree planting, and increasing the green area. However, in the process of seedling production in my country at present, there are few systematic studies on seedling root promotion and fertilization technology. People are very blind t...
