摘要

研究了平原高沙土地区合理种植、水旱轮作、合理轮耕和秸秆还田增肥改土技术对土壤理化性状的影响。结果认为"两旱一水

两年五熟"不仅产量高

而且土壤理化性状得以改善;水旱轮作可增加土壤黏粒含量

提高高沙土肥力水平;合理轮耕可充分发挥少免耕的优势

达到增肥、改土、省工的目的;通过稻麦留高茬和玉米秸秆还田

可直接提高土壤肥力

从而提高农作物产量。该试验与推广取得了明显成效

促进了生态农业良性循环。

Abstract

The effects of rational planting

the paddy upland system

rotational tillage and mulching corn straws on physical and chemical characteristics of soil with high content sands of plain area were studied. The results showed that the system of "twice upland aod one paddy

five times cereal cropping system in two years" could not only raise crop production

but also improve the physical and chemical properties of soil. The paddy upland system increased clay dispersion content and soil fertility. The rotation tillage

minimum tillage and non tillage practices were beneficial to improve soil fertility

increase soil properties and save man power. The mulching corn straws had very significant profit on raising soil fertility and crop yield. The experiment and its application were successful and may support a virtuous cycle of eco agriculture.
