Problems solved by technology

[0004] The Ministry of Land and Resources promulgated the "Standards for Land Development and Consolidation" in 2000. The standard stipulates the general principles, content, procedures, methods and basic requirements for the planning of land development and consolidation projects, as well as the principles, content and technical requirements of project design. However, the standard There are no technical measures involving rapid fertilization of the prepared soil and improvement of soil productivity

Embodiment 1

[0059] 1. Soil surface finishing

[0060] The land after the acceptance of the land consolidation project will be further leveled to ensure that the soil block particles are not larger than 5cm, and the small stones with a diameter of more than 5cm in the soil shall be cleaned up.

[0061] 2. Implement accurate soil testing and fertilization

[0062] After the land consolidation is completed, according to the shape of the consolidation field and the owner of the household, the "S" or "diagonal" method is used to collect soil samples of 0-15 cm layer according to a sampling unit of 2-3 acres and send them to a qualified institution for testing The soil organic matter, large and medium-trace element content; then analyze the soil fertility status of each sampling unit, formulate the fertilization formula of the sampling unit field, when the crop is tobacco, nitrogen (N), phosphorus (P) 2 O 5 ), potassium (K 2 O) The application rate is: 120-165kg / hm 2 , 120-165kg / hm 2 , 375-450kg / hm 2 ...

Abstract

The invention discloses a method for rapidly fertilizing soil in a land consolidation area, which comprises the following steps: 1. Soil surface finishing; 2. Implementing soil testing and fertilization; 3. Reapplying farm manure; 4. Planting and overturning leguminous green manure; 5. Increase the proportion and frequency of topdressing with chemical fertilizers; 6. Add biological agents. The invention solves the problems of low organic matter content and insufficient fertility in the soil of the remediation area. Reduce nutrient loss due to poor soil structure in the remediation area, thereby increasing the utilization rate of chemical fertilizers to achieve the purpose of economical fertilization. By adjusting the reasonable amount and proportion of nitrogen, phosphorus, potassium and trace elements, the crops can get a comprehensive and reasonable nutrient supply, maximize the potential of crop production and improve economic benefits.

Description

technical field [0001] The invention relates to a soil fertilization method, in particular to a method for rapid soil fertilization in a land consolidation area. technical background [0002] Land consolidation refers to the comprehensive improvement of fields, water, roads, forests, and villages by taking various measures to improve the quality of cultivated land, increase the effective area of ​​cultivated land, and improve the agricultural ecological conditions and ecological environment. As an important means of coordinating the relationship between man and land and realizing the optimal allocation of land resources, land consolidation is the foundation and guarantee for the development of modern agricultural construction, and it is also an important means of improving the quality of cultivated land in our country. [0003] In the process of land consolidation, due to the adoption of engineering improvement measures, the plow layer soil is destroyed or buried, and the or...
