Problems solved by technology

Controlled-release fertilizers have beneficial effects such as reducing nutrient loss, increasing fertilizer utilization efficiency, improving soil structure, increasing yield, and improving crop quality. However, the current special slow-release fertilizers have only one nitrogen release peak, which is not suitable for different growth periods of crops. growth demand, which may easily lead to low fertilizer use efficiency and slow increase in crop yield
At the same time, this type of fertilizer is mainly invented for the release rate of fertilizer nutrients, without taking into account the loss and volatilization of those released nutrients that are not absorbed by plants
[0004] In addition, the price of special controlled-release fertilizers currently on the market is relatively high; the nutrient distribution ratio of products is poorly targeted; there are few special controlled-release fertilizer products for medium and low value-added crops such as vegetables and grains, and the fertilizer effect is average.

Abstract

The invention provides a controlled-release organic fertilizer. The controlled-release organic fertilizer is characterized by comprising the following raw materials in parts by weight: 20 to 40 parts of germ bran, 0.05 to 0.2 part of a composite microbial agent, 3.3 to 3.7 parts of urea, 0.8 to 1.2 parts of monoammonium phosphate, 2.3 to 2.7 parts of potassium chloride, 0.2 to 0.5 part of Brassinolide, 1 to 3 parts of Polyacrylamide, 2 to 6 parts of humic acid and 2 to 5 parts of furfural residue. The controlled-release organic fertilizer provided by the invention has the advantages of low production cost, strong pertinence, water retention, nutrient preservation, and good nutrition control effect.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a controlled-release organic fertilizer. Background technique [0002] The main defect of quick-acting chemical fertilizers is that the nutrient supply pattern is not consistent with the nutrient absorption of crops (including vegetables), and cannot meet the high-intensity demand for nutrients in the stage of rapid biomass accumulation of crops. Reasonable) lead to relatively low fertilizer utilization efficiency of current plants (such as stem vegetables) and increase the risk of environmental pollution. [0003] Controlled-release fertilizers are fertilizers that delay the initial release of nutrients by various regulatory mechanisms, prolong the effective period for plants to absorb and utilize their effective nutrients, and make their nutrients release slowly or controlledly according to the set release rate and release period. Controlled-release fertilizers hav...
