Agricultural soil improvement biological fertilizer

Abstract

The invention discloses an agricultural soil improvement biological fertilizer which is characterized by including the following materials in parts by weight: 28-30 parts of urea, 5-9 parts of ammonium sulfate, 11-18 parts of potassium polymetaphosphate, 2-9 parts of chinaberry bark, 5-8 parts of loquat leaf, 2-8 parts of castanopsis fargesii sawdust, 1-6 parts of robur sawdust, 4-8 parts of magnesium phosphate, 5-11 parts of manganese hypophosphite, 12-24 parts of flax straw, 25-30 parts of hemp straw, 45-50 parts of sunflower straw and 0.01-0.03 part of bdellovibrio powder. The agricultural soil improvement biological fertilizer has good water absorption performance, good water retention properties, and comprehensive plant nutrition elements, and can improve the soil physical properties and restore soil fertility.

Description

technical field [0001] The invention relates to an agricultural soil improvement biological fertilizer. Background technique [0002] At present, the proportion of chemical fertilizers used in agricultural production is increasing day by day. Due to the effect of chemical fertilizers, soil humus is reduced and soil is hardened, resulting in reduced soil fertility and water retention performance. Therefore, in addition to increasing the amount of chemical fertilizers used , is also prone to drought, resulting in crop failure, so there is an urgent need for a fertilizer, which can not only increase the supply of fertilizers, ensure sufficient nutrients for plants, but also help soil water and fertilizer retention, which is conducive to the growth of crops. growth and ensure stable crop yields. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an agricultural soil improvement biological fertilizer. [0004] In order...

[0002] At present, the proportion of chemical fertilizers used in agricultural production is increasing day by day. Due to the effect of chemical fertilizers, soil humus is reduced and soil is compacted, resulting in reduced soil fertility and water retention performance. Therefore, in addition to increasing the amount of chemical fertilizers used , is also prone to drought, resulting in crop failure, so there is an urgent need for a fertilizer, which can not only increase the supply of fertilizers, ensure sufficient nutrients needed by plants, but also help soil water and fertilizer retention, which is conducive to the growth of crops. growth, to ensure stable crop yields
