Example Embodiment

[0022] Embodiment Basically, a kind of fast fertilization method of newly remediation ground soil comprises the following steps:

[0023] (1) Optimization of land improvement: In hilly areas, excavators are used to open drainage ditches (60 cm wide and 50 cm deep) according to the original terrain. After the land is leveled, the water in the soil can drain naturally; the land consolidation in each area The loach-backed middle height is low on both sides, so that the water in the soil can drain naturally, avoiding continuous rainy weather or heavy rain, the rainwater cannot be discharged from the soil smoothly, resulting in poor growth or death of plants with accumulated water; Divided into small blocks, each small block has an average length and width of more than 20m, which is conducive to the operation of the excavator; in the process of optimizing leveling, the leveling depth reaches more than 40cm;

[0024] (2) Organic fertilization: spread organic fertilizer 1-2 tons / mu o...

Abstract

The invention belongs to the technical field of agricultural fertilization, and particularly discloses a fast fertilization method for newly-regulated soil, which includes the following steps: (1) optimizing the regulated soil; (2) organic fertilization; (3) biological fertilization: laying out earthworms according to 40-45kg/mu in each area after the step (2), watering 130-150kg/mu after stocking, covering rice straws with a thickness of 8-10cm, standing for 10-15 days, and carrying out biological fertilization by using the earthworms; (4) rotation and fertilization: adopting a sorghum and broad bean rotation mode in each area after step (3), and applying a compound fertilizer and a microbial fertilizer with strong soil fertility during sorghum planting; and (5) straw crushing and returning to the field: crushing the straws and returning to the field in each area in the step (4), and re-promoting the improved soil organic matters. The method is mainly used for agricultural fertilization and solves the problems of poor soil configuration, large difference in physical properties, non-uniform nutrients and unhealthy risks of soil quality in cultivated land after soil replacement in newly-regulated areas in the prior art.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilization, and specifically discloses a method for rapid fertilization of newly rehabilitated soil. Background technique [0002] With the acceleration of industrialization and urbanization, the number of cultivated land is decreasing, the quality of cultivated land is declining, and the reserve resources of cultivated land are insufficient. In order to develop the reserve resources of cultivated land, increase the area of ​​cultivated land, and improve the efficiency of land use, my country has carried out land consolidation work. Land remediation refers to the remediation of land damaged by inefficient use, irrational use, unused production and construction activities and natural disasters, and the improvement of land use efficiency, including land reorganization, land reclamation and land development. In my country, the combination of land consolidation and rural development, especial...
