茶树是我省的主要经济作物,对磷素营养要求较高。据调查我省绝大部分的茶园土都普遍存在着缺磷现象,对茶树的生长、茶叶的品质产生了不良的影响。VA菌根菌能与茶树的幼根形成共生体,能增进茶树的吸磷作用,促进茶树生长。为了节约磷肥,充分发挥菌根对茶树的增产效应,本试验就菌根菌在不同施磷水平下对茶树生长的影响进行了研究。 Tea tree is the main economic crops in our province, higher requirements on phosphorus nutrition. According to the survey, most tea plantations in our province are generally lack of phosphorus, the growth of tea, the quality of tea had a negative impact. VA mycorrhizal fungi can form symbiosis with the young root of tea tree, which can enhance the phosphorus uptake of tea tree and promote the growth of tea tree. In order to save phosphate fertilizer and give full play to mycorrhizal yield-increasing effect on tea plant, the effect of mycorrhizal fungi on the growth of tea plant under different phosphorus application was studied in this experiment.
