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 that has passed the acceptance of the land consolidation project will be further leveled to ensure that the soil particles are not larger than 5cm, and the small stones with a diameter larger than 5cm in the soil will be cleaned up.

[0061] 2. Implement accurate soil testing and fertilization

[0062] After the land consolidation is completed, according to the shape of the sorted field and the owner of the household, use the "S" or "diagonal" method to collect soil samples at 0-15cm level according to a sampling unit of 2-3 mu, and send them to institutions with testing qualifications for testing The content of organic matter, major and medium and trace elements in the soil; then analyze the soil fertility status of each sampling unit, and formulate the fertilization formula for the sampling unit field. When the crop is tobacco, nitrogen (N), phosphorus (P 2 o 5 ), potassium (K 2 O) The application rates are: 120-165 kg / hm...

Abstract

The invention discloses a method for rapid soil fertility in a land consolidation area. The method comprises the following steps: 1, consolidating soil surface; 2, implementing soil testing and fertilizing; 3; fertilizing lands with farmyard manure heavily; 4, planting, turning over and pressing leguminous green manure; 5, increasing the ratio and the number of times of chemical fertilizer topdressing; 6, adding biological agents. According to the invention, the problems that organic content is lower and fertility is inadequate in the soil of the land consolidation area are solved; nutrient loss caused by poor soil structure in the land consolidation area is reduced, so that the utilization rate of fertilizers is increased to reach the purpose of economic fertilization; through regulating the reasonable dosage and ratio of nitrogen, phosphorus, potassium and microelements, plants are enabled to obtain comprehensive and reasonable nutrients, and the yield-increasing potential of the plants can be most fully developed to improve economic returns.

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 o...
