郑杂棉4号套作小麦双丰技术研究

摘要

Objective] To explore the bumper harvest technology of Zhengzamian No.4 interplanting wheat.[Method] The contrast experiment between Zhengzamian No .4 interplanting wheat planted by 4-1 type and the same area of single cotton was conducted in Zhongmou Yellow River beach and Xushui testing ground, and a comparative analysis between Zhengzamian No.4 interplanting wheat and the same area of single cotton was done in the comprehensive performance, yield and economic benefit.[Result]The experimental results showed that Zhengzamian No.4 inter-planting wheat could relieve plant diseases and insect pests and was good for emergence of all seedlings; the average yield of single cotton was higher than that of the cotton in Zhengzamian No .4 interplanting wheat; The economic benefit of Zhengzamian No .4 interplanting wheat was 8 380.5 yuan/hm2 more than that of single cotton.[Conclusion]The interplanting mode can improve land utilization, realize continuous produc-tion of wheat and cotton throughout the year , and provide a reference for wheat and cotton production .%[目的]探索郑杂棉4号套作小麦的双丰技术。[方法]在中牟黄河滩地和须水试验场，以相同面积的郑杂棉4号套种小麦与单茬棉花设置对比试验，麦棉套种按照4－1式种植，并对郑杂棉4号套种小麦与单种棉花的综合表现、产量、经济效益进行对比研究。[结果]郑杂棉4号套种小麦可减轻病虫为害，利于一播全苗；单种棉花平均产量高于郑杂棉4号套种小麦产量中棉花产量；郑杂棉4号与小麦套作较单茬棉花种植经济效益提高了8380．5元／hm2，增益显著。[结论]此套种模式提高了土地利用率，实现了全年麦棉持续生产，为棉麦生产提供了一定的参考。
