摘要
本文对红豆草的干物重、青干比、生长率、叶面积系数、净同化率和光能利用率等生物量特征值作了分析研究,从其内在的变化规律和它们之间的相互关系以及气象条件对其影响的结果中,得出盛花期为刈草最佳阶段,并提出了提高刈草量的关键措施。这对指导生产,提高产量和质量将起重要作用。
An analysis has been made on the characteristic values of biomass of Onobrychis viciaefolia, including weight of dry matter, ratio of green mass to dry mass, growth rate, leaf area index, rate of net assimilation, and efficiency for solar energy utilization. Based on the dynamics of various, their relationships with each other, and the effects of climatic conditions on them, it is concluded that the peak flowering period would be the best season of the grass harvest, and the key measures have been suggested to increase the grass yield.
