良种繁育的主要任务,一是加速繁殖种子,二是保持良种种性。国内外实践证明,干贮种子在良种繁育中的应用,对保存种子生活力,保持良种遗传性,具有显著的成效;采用常温干贮法,还具有就地取材、不耗能源,成本低,方法简便,易于推广等特点.这对长江两岸地区,由于温度高,雨量和空气湿度也高,一般散装或袋装的种子,不过一年就会丧失其发芽率的情况下,此法极为适用。 The main task of seed breeding, first, accelerate the breeding of seeds, and second, to maintain good seed variety. The practice at home and abroad proves that the application of dry storage seeds in seed breeding has significant effect on preserving seed viability and maintaining heritability of seeds and has remarkable effects. Drying at room temperature also has the advantages of local materials, no energy consumption, low cost, The method is simple, easy to promote and so on.This method is very suitable for this area of ​​the Yangtze River due to high temperature, high rainfall and air humidity, the general bulk or bagged seeds, but one year will lose its germination rate .
