耕作对健康耕层结构的影响及发展趋势
Effects of Tillage Model on Healthy Plough Layer Structure and Its Development Trends
摘要
Abstract
Soil cultivation is closely related to land productivity. Nutrient in plough layer is the key factor affecting the absorption and utilization of crop nutrients.Good plough layer structure is beneficial to the coordination of water,fertilizer,gas and heat.The depth of arable layer is related to tillage methods.Constructing good plough layer structure is conducive to crop growth and distribution.This paper reviewed both domestic and foreign researches regarding tillage models,which included conventional tillage,protective cultivation,rotary tillage,deep tillage,and so on.Based on the above research results,the effects of tillage models on the healthy soil layer construction were discussed from the soil bulk density,soil porosity,soil aggregates,infiltration of soil,soil heavy metals,soil respiration and the characters of root system.The deficiencies of current research were pointed out from several aspects such as tillage system,system positioning,tillage efficiency,suitable crop.In order to maximize the comprehensive production capacity of cultivated land resources and solve the contradiction between human being and land,this paper forecasted the development trend of ideal plough layer structure from four aspects:Cultivate patterns according to local conditions, the establishment of complex farming models, accelerating the research and application of new agricultural machinery, conducting systematic research of farmland microclimate environment.This will provide the theoretical basis and technical support for the optimal farming mode in agricultural production.关键词
