Method for improvement of acidic soil of wheat field and wheat cultivation method capable of increasing yield

Abstract

The invention discloses a method for improvement of acidic soil of a wheat field and a wheat cultivation method capable of increasing the yield. The invention aims to solve the technical problems, which are caused by soil acidification, in grain yield and safety. Through supplementary action of multiple technical measures, the pH value of the soil can be improved significantly, and the level of soil fertility can be improved, wherein the technical measures include adoption of a conditioning agent, preparation of reasonable nitrogen fertilizer, phosphate fertilizer and potassium fertilizer which are organic fertilizer and chemical fertilizer, combined application of deep ploughing and deep turning and reasonable selection of fertilizer types; the invention aims to provide the method for improvement of acidic soil of the wheat field and the wheat cultivation method capable of increasing the yield, and the methods need to be suitable for the Henan region, so that the acidic soil of the wheat field is improved, stable production and yield increase of wheat in the region are achieved, and the food security in China is ensured.

Description

technical field [0001] The invention relates to the technical field of wheat production, in particular to a cultivation method for improving acidic soil in a wheat field and increasing wheat production. Background technique [0002] At present, highly intensive modern agriculture is facing more and more serious problems of soil acidification. Soil acidification refers to the process in which the pH value of the soil decreases continuously and the exchangeable acid of the soil increases continuously. It is a natural process accompanied by the occurrence and development of the soil. It mainly produces hydrogen ions (H + )drive. Studies have found that the causes of soil acidification are complex and diverse, including both natural factors and more complex and frequent human activities. The causes and mechanisms of soil acidification in different regions are also different, and long-term and in-depth investigations and experimental studies are needed. Only then can a targeted...

Problems solved by technology

[0004] ①Soil fertility weakens: because the macro and micro elements in the soil such as N, P, K, Ca, Mg, S, Si, B, Mo are most effective when the soil pH is 6.0-7.0, and their effective ② Changes in the microbial community in the soil: bacteria and actinomycetes in the soil are more suitable for neutral and slightly alkaline environments; in strongly acidic soils, nitrifying bacteria, nitrogen-fixing bacteria, silicate bacteria, phosphorus bacteria etc. are inhibited, thereby inhibiting the conversion of N, P, K, S, Si, etc.; acidification will increase the activity of metal elements in the soil, which will have a toxic effect on crops; on the other hand, the deposition of acidic substances will reduce the enzymes in the soil activity; ③Increased content of aluminum ions in the soil: because the activity of aluminum ions increases under strong acidic conditions, and too much aluminum ions will cause poisoning to plants; h + 、Al 3+ Mainly, base ions are leached, clay minerals are altered, aggregate structure disintegrates, soil physical properties deteriorate, and soil buffering capacity decreases

This situation seriously threatens the security of food production
