西藏拉萨河谷地区紫花苜蓿的刈割管理
Cutting management of Medicago sativa in the Lhasa river valley, Tibet
摘要
Abstract
Through systematic research of the cutting areas in the Lhasa river valley, dynamic models of Medicago sativa growth were structured to simulate and forecast the accumulation of dry matter and fresh forage of M. sativa in different cutting schemes. The effects of cutting times on accumulation of dry matter and fresh forage, height, dry weight/fresh weight ratio, nutrient component of M. sativa were studied and different cutting schemes were developed to suit different objectives. Cutting three times a year at branching for M. sativa pasture gave the maximum dry matter and best quality of M. sativa hay in the Lhasa river valley.关键词
