广东地处亚热带,全年气温高、湿度大,稻谷在贮藏过程中,容易生虫、发热、霉变,给谷物安全贮藏带来很大困难。采用化学药剂杀虫的方法,对抑制虫、霉有一定效果,但每年要熏蒸2—3次,保管费用高。同时,较长期使用药剂,使仓库害虫产生不同程度的抗药性,使用药量要有所增加,如防护不慎,容易造成种子污染。在通常情况下,稻谷种子的发芽力只能保持一年至一年半,如果贮藏条件不好,保持时间还会缩短,造成生产用种的困难。因此,种子寿命及其延长方法的研究,一直成为种子学
Guangdong is located in the subtropical zone with high temperatures and high humidity throughout the year. Rice is prone to pests, fever and mildew during storage, which poses great difficulties for the safe storage of cereals. The use of chemical insecticide methods to inhibit insects, mold has a certain effect, but fumigation 2-3 times a year, keeping costs high. At the same time, longer-term use of pharmaceutical agents, so that the warehouse pests have different levels of resistance, the use of drugs to be increased, such as carelessness, likely to cause seed pollution. Under normal circumstances, the germination power of rice seeds can only be maintained for a year to a year and a half, if the storage conditions are not good, keep the time will be shortened, resulting in difficulties in the production of species. Therefore, the study of seed life and its extension method, has become a seed science
