采用植物生长分析法 ,研究了北疆高产( 1 80 0 kg· hm- 2 )棉花干物质积累与分配、叶面积指数、净同化率、相对生长率、群体生长率的动态变化规律 ,分析了北疆公顷产 1 80 0 kg高产棉花物质生产的特点 ,提出了各生育时期有关干物质生产分配的生理指标
The dynamic changes of dry matter accumulation and distribution, leaf area index, net assimilation rate, relative growth rate and population growth rate of high yielding (180 kg · hm-2) cotton in northern Xinjiang were studied by using plant growth analysis. The characteristics of production of high-yielding cotton with a yield of 1 800 kg ha in the northern Xinjiang were put forward. The physiological indicators of the distribution of dry matter production in each growth period
