为研究供水量对绿豆的影响,确定适宜绿豆苗期生长的水分条件,在绿豆生长季节模拟降水量设4种不同供水量处理,测定绿豆苗期生长形态指标和各器官干物质积累。结果表明,供水量不足时,绿豆株高降低,叶片减少,地上部、地下部和总生物量均降低;绿豆虽然比较耐旱,适当增加供水量有利于苗期生长,综合长势和生物量,绿豆生长季节降水量350 mm比较适宜,绿豆地上部与地下部生长协调,各器官物质分配合理,为绿豆进一步分枝、结荚等生殖生长和提高经济产量奠定基础。
In order to study the effect of water supply on mung bean and to determine the suitable water conditions for the growth of mung bean at seedling stage, four different water supply treatments were set up to simulate the precipitation in the mung bean growing season, and the growth morphological indexes and dry matter accumulation of each organ were measured. The results showed that when the water supply was insufficient, the plant height of mungbean decreased, the number of leaves decreased, and the aboveground part, underground part and total biomass decreased. Mungbean was more tolerant to drought and suitable water supply increased the seedling growth and comprehensive growth and biomass, The growth of mung bean during the growing season is more suitable for 350 mm. The growth of mung bean is coordinated with the growth of the lower part of the ground and the distribution of the materials in various organs is reasonable. This will lay the foundation for further growth and yield increase of the mung bean.
