春耕与秋耕对草原土壤理化性质影响的研究

The influence of spring and autumn ploughing on physical andchemical characters of soil

分析了土壤理化性质及土壤含水率季节动态,研究了春耕与秋耕分别对草原土壤理化性质的影响。结果表明,秋耕地比春耕地更有利于维护草原土壤的理化性状,同时也更有利于作物的良好生长。因此,在草原干旱区开垦农田,应以秋耕为主要耕作方式。

This project was conducted to study the influence of spring and autumn ploughing on the physical and chemical characters of soil and the change of moisture content in farmland. The results showed that autumn ploughing was more beneficial to improve the physical and chemical characters of soil than spring ploughing. Therefore, autumn ploughing should be applied as a major pattern of cultivation in the farmlands in dry pasture regions.
