Problems solved by technology

[0005] The existing sandy soil farming still mainly uses traditional chemical fertilizers and farmyard manures. The application of these fertilizers can only meet the temporary nutrient requirements of crops, and continuous application is required to ensure that crops can grow on sandy soil, and their growth is also difficult. Difficult to compare with normal soil, lower yield
The application of conventional chemical fertilizers and farmyard manures in sandy soils cannot solve the problem of poor water and fertility retention in sandy soils, and the fertilizer efficiency is low
Moreover, the continuous application of a large amount of chemical fertilizers has also led to serious soil acidification. The pH value of the soil is mostly between 5 and 5.5 or even lower, which is easy to cause dead seedlings, seed rot, and also easy to cause diseases and insect pests; the chain reaction has caused a large number of pesticides to be used. , inevitably causing pollution to crops and the environment
Not only can not solve the problem of sandy soil, but aggravated the deterioration of sandy soil conditions
Although the side effects of farmyard manure are not as great as that of chemical fertilizer, its fertilizer effect is released slowly. It needs to be continuously applied or combined with chemical fertilizer application to keep crops growing on sandy soil. It has poor performance in improving sandy soil fertilizer and water retention. can't do anything about the problem

Abstract

The invention provides a sandy soil improver and belongs to the technical field of soil improvement. The sandy soil improver is prepared from the following components in parts by weight: 60 to 80 parts of bamboo fermenting product, 15 to 25 parts of humic acid, 1 to 8 parts of calcium superphosphate and 0.05 to 0.5 part of complex microbial inoculant, wherein the complex microbial inoculant is prepared from bacillus amyloliquefaciens, bacillus subtilis, bacillus licheniformis, bacillus mucilaginosus, bacillus latersprorus, photosynthetic bacteria, lactic acid bacteria, saccharomycetes and fermented filamentous bacteria. Tests show that after the sandy soil improver provided by the invention is applied, per unit area yield of crops planted in aeolian sandy soil is improved by 20 percent orabove, acid soil is changed into neutral soil, and granular structures of the soil is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a sandy soil improver and its application. Background technique [0002] Aeolian sandy soils are soils developed from aeolian sandy parent materials. Its main feature is that the soil mineral part is almost entirely composed of fine sand particles (0.25-0.05 mm in diameter); the stratification of the section is not obvious, only the A layer (leaching layer) and C layer (parent material layer) lack the B layer (sediment layer). stratification), severe wind erosion. Aeolian sandy soils are mainly found in temperate semi-arid, arid, and extremely arid grasslands, desert grasslands, and desert areas, and some are located on the seashore. [0003] The texture of aeolian sandy soil is coarse, and the fine sand grains account for more than 80-90% of the weight of the mineral part of the soil, while the content of coarse sand grains, silt grains and clay grains is very small. ...
