宁南山区红梅杏幼林间作茶用菊的适应性研究与初步评价

Study and Preliminary Evaluation on Adaptability of Intercropping Chrysanthemum for Tea in Hongmei Apricot Orchard in Southern Ningxia

通过在红梅杏幼林间作茶用菊对红梅杏生长量、林地土壤理化性质和对土壤酶含量的影响及茶用菊的适应性等进行研究。结果表明,红梅杏幼林间作茶用菊可有效提升红梅杏幼林地中层和深层土壤含水量,促进红梅杏幼树生长。间作茶用菊模式红梅杏树高、地径以及主分枝数比红梅杏纯林分别增加了8.25%、18.32%、18.18%,0~60 cm土壤有机质含量平均提高了13.58%,土壤酶含量有所提高。此外,间作茶用菊花可获得1100元/667 m2的纯收入。由此可见,红梅杏幼林间作茶用菊能有效促进红梅杏增产增收,具有一定的生态效益和经济效益。

In this paper,the effect of intercropping chrysanthemum for tea in Hongmei apricot orchardon growth,physical and chemical properties of forest soil and enzymecontent of soil and adaptability of chrysanthemum for tea intercropped in Hongmei apricot orchard were studied.The results showed that intercropping chrysanthemum for tea in Hongmei apricot orchard could effectively increase the soil water content in the middle and deep layers of the young red plum apricot forest to promote the growth of the young red plum apricot forest.Compared with the pure forest,the height,ground diameter and main branch number of the red plum apricot increased by 8.25%,18.32%,18.18%,respectively;soil organic matter increased by 13.58%;soil enzyme activity increased.In addition,net income of intercropping chrysanthemum for tea is 1100 yuan/667 m2.It is proved that intercropping chrysanthemum for tea can effectively promote crop yield and income,and has certain ecological and economic benefits.
