玉米间作菊花脑高效栽培方法对玉米杂草的影响

研究了玉米间作菊花脑的高效栽培方法对玉米杂草的影响,以探究此间作方法对杂草的防效及间作经济效益,为在生产实践中进一步推广应用提供理论依据。结果表明,玉米菊花脑间作处理(T)较玉米单作处理(CK),玉米产量增加,每667 m2产值增加2496元,增收效果明显;间作处理的玉米维生素C、粗淀粉、可溶性糖、可溶性蛋白含量分别提高了41.7%、3.6%、6.2%、14.2%;在玉米各时期CK处理杂草发生种类和相对密度均高于T处理;玉米成熟期T处理防草效果最好,株数防效和鲜质量防效分别达87.64%和90.28%,有效减少杂草生长。综上所述,玉米间作菊花脑的高效栽培方法有效减少了除草剂的用量,菊花脑经济效益更高,能在保证玉米产量的同时,显著提高农民收入。

Effects of High-efficiency Cultivation Method of Maize Intercropping with Chrysanthemum nankingense on Maize Weeds

In this paper,the effects of high-efficiency cultivation method of maize intercropping with Chrysanthemum nankingense on maize weeds were studied to explore the control effect of intercropping method on weeds and economic benefits of intercropping,and provide theoretical basis for further popularization and application in production practice.The results showed that compared with maize single cropping treatment(CK),the maize production value of maize intercropping with C.nankingense treatment(T)increased by 2496 Yuan/667 m2,and the increase effect was obvious.The contents of vitamin C,crude starch,soluble sugar and soluble protein increased by 41.7%,3.6%,6.2%and 14.2%,respectively.The species and relative density of weeds of CK treatment were higher than those of T treatment at each growth stage of maize.The control effect of T treatment was the best at the mature stage of maize.And the plant number and fresh weight were 87.64%and 90.28%,respectively,which effectively reduced the growth of weeds.In summary,the high-efficiency cultivation method of maize intercropping C.nankingense effectively reduced the amount of herbicide,and the economic benefit of C.nankingense was higher,which could guarantee the yield of maize and significantly increase the income of farmers.
