通过对水稻种子在不同温、湿度条件下进行周年贮存,探索出水稻种子在不同冷藏条件下其发芽率的变化规律。为水稻种子的低温贮藏选择合适的库温,同时也为科学安全贮藏水稻种子提供理论依据。1 材料与处理1.1 供试材料2009年生产的水稻种子:长粒香、A22、旱72冬季一般不在温室内保存越冬(塑纺织袋包装)。2010年春 Through the annual storage of rice seeds under different temperature and humidity conditions, the variation of germination rate of rice seeds under different cold storage conditions was explored. Select appropriate temperature for low temperature storage of rice seeds, and also provide theoretical basis for scientific storage of rice seeds safely. 1 Materials and Processing 1.1 Materials to be tested Rice seeds produced in 2009: Long grain, A22, dry72 Winter is generally not preserved in winter in the greenhouse (plastic woven bag packaging).
