[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 shading with different densities on the growth, yield and yield of maize and Glechoma longituba. [Method] The density of corn was designed by random block design. There were 5 treatments and 3 repetitions with the spacing of 170 cm and the spacing of 49, 30, 22, 17 and 14 cm respectively, that is, the density was 12,000, 19,500 and 2.70 Million, 34,500, 42,000 plants / hm2. Even the planting density of Qiancao was 159,500 plants / hm2. [Result] When the intercrop density of corn was between 19,500 and 27,000 plants / hm2, the growth and development of Liannonggrass was better and the quality, yield and income were higher. [Conclusion] The study provided a scientific basis for solving the problem of both prostrate growth and gratification of hippophae rhamnoides, and it was a tradition to change the main way of cultivating farmers to cultivate corn rather than cultivate herbs Kind of medicine to provide guidance.
