| 摘 要： | 通过对水稻旱作覆膜条件下不同生长阶段的不同土壤水分控制指标对水稻生育性状及产量影响的试验研究 ,分析得出水稻旱作覆膜条件下的水分敏感期为拔节孕穗期。试验结果表明 :分蘖期、拔节孕穗期、抽穗开花期、乳熟期的适宜灌水下限分别为 70 %、85 %、80 %和 70 %。这为合理灌溉提供了可靠依据

| Abstract: | An field experiment was carried out for determining suitable soil moisture control index for dry farming rice mulched with plastic. Results shown that the critical stages for water application in dry farming rice are elongation stage and booting stage. It also can be concluded that the suitable lower limit of soil moisture are 70%, 85%, and 70% of field capacity for tillering stage, period from elongating to earring, and period from earring to milk stage respectively. |
