灌溉量对春小麦地上部分生物量积累及分配规律的影响
Effeet of Irrigation Quota on the Biomass Accumulation and Distribution of Spring Wheat
摘要
Abstract
A study was made on effects of different irrigation quota on the growth and yield of spring wheat in field conditions. The results showed that there was unfavorable to the biomass accumulation of plant height, leaf, leaf sheath and the spring wheat Ear-kernel under the 3000m3·hm-2 (1500m3·hm-2 less than comparison treatment). The growth and yield of spring wheat in spring wheat whole growth the water shortage was serious. There was high biomass accumulation under irrigation quota of 3600m3·hm-2 (900m3· hm -2 less than comparison treatment), but it declined in reproductive stage. The highest biomass accumulation under irrigation quota of 4200m3·hm-2 (300m3·hm-2 less than comparison treatment)during the period of wheat growth. Under the four irrigation quota the proportion of wheat biomass allocation is: The highest proportion of Ear-kernel, followed by stem and leaf sheath, the finally was leaf. In common years,fitting irrigation quota was 3900~4200m3·hm-2 and the biomass accumulation and distribution was the best reasonable.关键词
