Conditioning method of grape acidic soil

Abstract

The invention belongs to the technical field of agricultural planting, and particularly discloses a conditioning method of grape acidic soil. The conditioning method comprises the following steps: (1) treatment of grape planting site soil: loosening the soil of the grape planting site, turning up uniformly, and flattening; spraying a water solution obtained by soaking plant ash, and turning up until the soil is just moist; (2) soil conditioning: after the soil in the step (1) becomes dry, uniformly spraying a soil conditioner on the soil surface, and turning up uniformly; and (3) fermentation process: after turning up uniformly, covering a mulching film on the soil, keeping for 1 month, removing the film, turning up the soil, and naturally airing for 3-5 days, thereby completing soil conditioning. The conditioning method effectively changes the acidic soil state of the grapes, increases the water / air permeability and nutrition of the soil, effectively inhibits the harmful bacteria in the soil, and greatly promotes the favorable development of grape planting.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of agricultural planting, in particular to a method for regulating grape-acid soil. [0003] 【Background technique】 [0004] In some areas of our country, it is hot and rainy, and the weathering is deep. Due to the heavy rain, most of the alkaline components in the soil are lost, and the acidic substances such as iron and aluminum that are not easy to lose are relatively accumulated. Due to the increase of aluminum, the soil is acidic or strong. acidic. The following factors can increase soil acidification: [0005] (1) With the discharge of automobile exhaust and industrial sulfur dioxide, air pollution is caused, and industrial acid rain is formed; [0006] (2) Long-term use of fertilizers, especially acidic fertilizers, such as superphosphate, potassium chloride and potassium sulfate, etc.; [0007] (3) Long-term spraying of acidic herbicides such as paraquat and glyphosate. [0008] For grape...

AI Technical Summary

Problems solved by technology

[0009] (1) The absorption efficiency of nutrients such as phosphorus, potassium, calcium, magnesium and molybdenum by grapes becomes lower, which easily causes nutrient loss or waste;

[0010] (2) The cation exchange capacity of the soil becomes lower, which can easily cause calcium and magnesium deficiency in grapes, and increase the probability of physiological diseases

[0011] (3) It is easy to cause soil compaction, resulting in less air and space in the soil, which is not conducive to root growth;

[0013] (5) Beneficial bacteria such as decomposing organic matter and transforming nitrogen, phosphorus and other elements, and beneficial organisms such as earthworms are not easy to survive, which will reduce the number and activity of beneficial organisms;

[0014] (6) The soil is easy to breed fungi and bacteria, which can easily cause root rot and aggravate the harm of nematodes

There are certain deficiencies in using these amendments to improve acidic soil, either the cost is high and it is a non-renewable resource, or it can change the acidity of the soil but at the same time increase the adverse phenomena such as soil compaction
