郑杂棉4号套作小麦双丰技术研究

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8 380.5元/hm~2,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。

Study on Bumper Harvest Technology of Zhengzamian No.4 Interplanting Wheat

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 .
