在植物生理、生态以及大田农作物生产科学研究中,常常需要对所研究的特定植物群体、种群、群落生物量的年、月或旬、周变化进行测定,以估算出植物群体的原初生产力。经典的一些方法,如干重法、抽样收获法,严格地说是非连续性的和破坏性的,而且操作繁锁,时耗很大,不适宜对大数量、大范围以及特殊环境中的植物群体生物量进行测定。本文介绍一种国外新近发展起 In the plant physiology, ecology and field crop production sciences, it is often necessary to determine the annual, monthly, or ten-day and weekly changes in the biomass, plant population, and community biomass of the study population in order to estimate the primary productivity of the plant population. Some of the classical methods, such as dry weight method, sampling method, strictly speaking non-continuous and destructive, and cumbersome operation, time-consuming, not suitable for large quantities, large areas and plants in special environments Population biomass was measured.
