3种耕作和播种方式对小麦群体建成和产量的影响

Effects of Three Tillage and Seeding Methods on Population Formation and Yield of Wheat

为探讨2BMXS-4/12智能免耕施肥覆盖旋播机对小麦生长发育和产量的影响,采用3种耕作和播种方式对不同处理的小麦单株性状、群体建成进行测定,分析了产量及其组成因素间的回归和相关关系。结果表明,与传统的耕作和播种方式相比,智能免耕施肥覆盖旋播机能增加小麦株高、茎蘖数、主茎叶片数和次生根,可以获取较高的籽粒产量、经济效益、产出投入比和成本利润率。智能免耕施肥覆盖旋播机具有智能化程度高、简单易行、省工省时省成本、提高经济效益等优点,是值得大力推广的一种机械和耕作播种方式,也符合河南省"十三五"重点推广的小麦耕播技术规划。

In order to explore the effect of 2 BMXS-4/12 intelligent tillage-free fertilizing and mulching rotary seeder on the growth,development and yield of wheat,the individual character and population formation of wheat under different treatments were determined by using three tillage and seeding methods.And the regression and correlation between yield and its components factors were analyzed.The results showed that compared with the traditional tillage and seeding methods,the intelligent tillage-free fertilizing and mulching rotary seeder could increase plant height,tiller number,main stem leaves and secondary rooting of wheat.It could obtain higher grain yield,economic benefit,output-input ratio and cost-profit ratio.The intelligent tillage-free fertilizing and mulching rotary seeder had the advantages of highly intelligent,simple operation,effort-,time-and cost-saving,as well as being able to boost economic benefit.It is a mechanical tillage and seeding method worthy of more extensive promotion.It also conforms to the wheat tillage and seeding technology plan popularized by the 13 th Five-Year Plan in Henan.
