Problems solved by technology

Long-term use of inorganic chemical fertilizers by people can easily lead to a decrease in soil fertility, which not only destroys the acid-base balance of the soil, but also causes problems such as soil compaction and salinization; the nitrate content in agricultural products exceeds the standard and the quality deteriorates
Using organic fertilizers (mainly traditional farmyard manures) to replace inorganic fertilizers to produce pollution-free agricultural products has the advantages of improving soil fertility and crop quality, but the disadvantages of organic fertilizers are slow fertilizer efficiency and little increase in crop yields. If you want to To increase production, it is necessary to greatly increase the application of organic fertilizers
However, due to the limited organic fertilizer resources, it is far from meeting the needs of modern agricultural development, especially for melon, fruit and vegetable crops.

Abstract

The invention discloses a seaweed fertilizer with a stress resistance function. The seaweed fertilizer with the stress resistance function is prepared by the following raw materials by weight: 100-150parts of seaweed residue, 20-40 parts of cassava residue, 10-15 parts of wormcast, 0.3-0.5 parts of a fermentation preparation, 0.2 parts of a fermentation accelerant, 50-90 parts of a nitrogen phosphorus and potassium fertilizer, 20-40 parts of attapulgite, and 2-4 parts of dispersive aggregate. The seaweed fertilizer with the stress resistance function has the characteristics of rational formula, balanced nutrition, and obvious ecologic and economic benefits, and is capable of adequately satisfying the nutrient renewal of crops, expressing the efficacy of the fertilizer in the maximum degree, improving the yield, and improving the quality.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a seaweed fertilizer with anti-stress effect. Background technique [0002] Chemical fertilizers (referred to as chemical fertilizers) include two types of inorganic fertilizers and organic fertilizers; in terms of form, they can be divided into two types: solid fertilizers and liquid fertilizers. Fertilizer plays a significant role in increasing crop yield and is an indispensable production factor in modern agriculture. People's long-term use of inorganic fertilizers can easily lead to a decrease in soil fertility, which not only destroys the acid-base balance of the soil, but also causes problems such as soil compaction and salinization; the nitrate content in agricultural products exceeds the standard and the quality deteriorates. Using organic fertilizers (mainly traditional farmyard manures) to replace inorganic fertilizers to produce pollution-free agricult...
