摘要
[目的]研究不同密度间套遮阴对玉米和连钱草(Glechoma longituba)生长发育、产量及收益的影响。[方法]玉米密度采用随机区组设计,共设5个处理,3次重复,行距均为170cm,株距分别为49、30、22、17、14cm,即密度分别为1.20万、1.95万、2.70万、3.45万、4.20万株/hm2。连钱草的种植密度为15.95万株/hm2。[结果]玉米间套密度在1.95万～2.70万株/hm2时,连钱草的生长发育较好,且质量、产量和收益较高。[结论]该研究为解决既要满足连钱草的匍匐生长,又要满足其喜阴喜光习性的问题提供了科学依据,且为改变药农以栽培玉米为主而不是以种植药材为主的传统种药方式提供指导。
[Objective]The research aimed to study the effects of different inter-cropping density on growth,development,yield and income of Glechoma longituba and corn. [Method]5 treatments on corn were designed with 3 times repeated by the randomized block design,and the planting density were 1. 20 ×10^4,1. 95 ×10^4 -2. 70 ×10^4,3. 45 ×10^4,4. 20 ×10^4 plants per hectare respectively. The planting density of Glechoma longituba was 15. 95 ×10^4 plants per hectare. [Result]When the planting density of corn was 1. 95 ×10^4 -2. 70 ×10^4 plants per hectare,the growth ,development of Glechoma longituba was good,yield its quality,yield and income was high. [Conclusion]The study can provide scientific basis for solving the problems on meeting the creeping growth and shade-loving and light-loving simultaneously,and can provide guidance for changing the traditional planting way of herb.
