Soil changing method for solving continuous cropping obstacle problem of mountain pseudostellaria root planting

Abstract

The invention discloses a soil changing method for solving the continuous cropping obstacle problem of mountain pseudostellaria root planting. The soil changing method comprises six steps as follows: stand condition improvement, soil improvement, first-year planting soil treatment, second-year planting soil treatment, third-year planting soil treatment and recycling. Quicklime, farmyard manure and humus soil are used for performing nutrition improvement on soil, and the soil fertility can be enhanced while the soil is disinfected, so that factors such as the continuous cropping obstacle and the like caused by soil nutrient imbalance, organic matter content insufficiency and the like can be effectively eliminated; after ridge soil is treated with the method, sections or residues, left in the soil, of pseudostellaria roots can be reduced, planting soil used every year is renewed and can be recycled, the continuous cropping obstacle is overcome, and continuous cropping of the pseudostellaria roots in the same area is realized.

Description

technical field [0001] The invention relates to a method for solving the problem of continuous cropping obstacles in mountainous areas, in particular to a soil replacement method for solving the problem of continuous cropping obstacles for planting Pseudostellaria chinensis in mountainous areas. Background technique [0002] Crop planting, due to long-term cultivation of the same crop, is subject to factors such as the limitation of the crop and the imbalance of land nutrition, insufficient organic matter content, excessive salt accumulation, or poisonous secretions or residues left by crops in the soil, often resulting in " Continuous cropping obstacles", the use time of a piece of land must be limited by fallow due to continuous cropping obstacles, and can only be planted by planned rotation of different crops or reclaiming new land. Pseudostellaria Pseudostellariae is the dry root tuber of Caryophyllaceae ginseng, and it is the main economic crop in Zherong, Fujian and ot...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome factors such as limited arable land, driven by economic interests, and planting conditions. With continuous cropping in the planting area, the plant growth is poor, the quality and yield of Pseudostellariae Radix Pseudostellariae are greatly reduced, and continuous cropping obstacles are becoming increasingly serious. The crop rotation method is not feasible for large areas of water-deficient mountainous areas, and the continuous cropping obstacles are very serious. It provides a soil replacement method that can effectively solve the problem of continuous cropping obstacles in mountainous areas.
