为了节约人力物力,减少稻种资源种植过程引起的人为和机械混杂,提高保种质量,在解决3年轮换种植1次的基础上(《广东农业科学》1981,4),结合广东高温多湿的气候特点,继续进行稻种资源多年贮藏试验。材料是广东早造籼稻地方品种(早籼贮存难度比晚籼为大)。1976年将收获的2245个品种烘干至含水量少于10％,放置在有足量硅胶的干燥器内,常温贮存,至1983年早造田间播植时测定各品种的发芽率,与1978年收获的2084个品种,同样烘干至含水量少于10％,种子用塑料袋(内放硅胶)密封包装置铁皮箱
In order to save manpower and material resources, reduce man-made and mechanical mixing caused by the planting of rice seed resources and improve the quality of seed bred, on the basis of resolving the three-year rotation and planting once (Guangdong Agricultural Sciences, 1981,4), combined with the hot and humid Guangdong Climate characteristics, continue to carry out storage of rice resources for many years. The material is Guangdong early Indica rice varieties (early indica storage more late indica). 2,245 varieties harvested in 1976 were dried to a moisture content of less than 10%, placed in a sufficient amount of silica gel dryer, stored at room temperature until 1983, early planting field determination of the germination rate of each variety, and 1978 2084 varieties harvested in the year, the same drying to less than 10% moisture content, plastic bags with seeds (placed in silica gel)
