摘要
在海拔2 800m 的格尔木地区生产苜蓿种子取得了成功,11 300m^2三龄紫花苜蓿种子产量达到了556.7kg。试验进一步表明,在格尔木的特殊气候条件下,苜蓿植株高大、花荚数多、结实率高.不倒伏,病虫害少。野生授粉蜂的活动为种子生产创造了有利的条件.在适宜的栽培管理条件下,苜蓿生长良好,种子生产具有较大的潜力。
Alfalfa seed production got a great success in Golmu area with an elevation of 2800 meters and higher seed yield of 556.7kg was given in 11300 square meters.The results showed that under special climatic condition in Golmu,the alfalfa plant has much height,a great number of flowers and pods,high rate of podding,little lodging and pest.The wild bees for alfalfa seed pollination often contribute to seed producton in this area.Alfalfa grows well and has great potentiality in seed production under good culture and management practice.
