Problems solved by technology

In recent years, due to the unreasonable use of chemical fertilizers, although crop yields have been increased in a short period of time, the imbalance of nutrient ratios in some farmlands in Shajiang black soil has been exacerbated, the farmland ecosystem has further deteriorated, and soil physical and chemical properties and soil microbial flora have been affected to varying degrees. damage, seriously affecting the sustainable development of regional agriculture, so it is not a fundamental solution

Embodiment Construction

[0018] A method for improving the sand ginger black soil field, realized by the following steps:

[0019] (1) Give full play to the role of existing ditches and other water conservancy drainage and irrigation facilities, and improve the water conservancy drainage and irrigation facilities.

[0020] (2) Return all crop stalks to the field.

[0021] (3) Increase the special organic fertilizer of sand ginger black soil to improve the soil physical properties of sand ginger black soil.

[0022] (4) Deep plowing and deep loosening of the soil to improve the crop's ability to absorb nutrients.

[0023] (5) Implementing the full amount of straw crops to the field not only has a good soil improvement effect in Shajiang black soil, but also has a significant increase in the yield of the next crop.

[0024] (6) Add more than 100 kilograms of commercial organic fertilizers to fully improve the physical properties of the Shajiang black soil field.

[0025] (7) Deep plowing and deep loo...

Abstract

The invention relates to an improvement method for soil, specifically to an improvement method for lime concretion black soil. the method overcomes the problems that water, nutrient, air and temperature of lime concretion black soil are in an unharmonious relationship and the level of fertility is low, etc. The improvement method for lime concretion black soil gives full play to conventional water-conservancy irrigation-and-drainage facilities such as irrigation canals and ditches in order to continually perfect water-conservancy irrigation-and-drainage facilities, carries out total returning of crop straw to lime concretion black soil field, increases organic fertilizer application in order to improve physical properties of lime concretion black soil, and carries out deep-plowing and deep-loosening on lime concretion black soil in order to increase nutrient absorption capability of crops. The improvement method for lime concretion black soil field provided by the invention uses a step of increase of organic fertilizer application to improve lime concretion black soil on the basis of a traditional improvement method for lime concretion black soil, so the problem that the improvement method for lime concretion black soil in the prior art cannot fundamentally achieve the objective of soil recovery is overcome and soil resources in our country are effectively saved; meanwhile, the improvement method has the advantages of low cost, convenient operation, high practicability, etc.

Description

Technical field: [0001] The invention relates to a method for improving soil, in particular to a method for improving sand ginger black soil fields. Background technique: [0002] my country is a large country with a population of 1.3 billion, and its per capita land resources are lower than the world average. However, we are still facing the irreversible situation of the decrease of cultivated land and the increase of population. The protection and rational development of land resources is a matter of today's benefit and achievement. In Qianqiu's career. In our country, as a soil resource, Shajiang black soil has an area of ​​about 60 million mu and has great potential. [0003] Shajiang black soil is one of the important low-yielding soil types in my country. It is mainly distributed in the Huanghuaihai Plain, with an area of ​​about 60 million mu. The Shajiang black soil distribution area has relatively rich light, heat, water and soil resources, and is an important comm...
