板栗靠果实种子繁殖,果实含水量较高,没有经过杀虫的种子,在温度、湿度高的地方,存放20多天,就有30％左右的种子被虫损失发芽力,而这些损失的种子,外表又不易看出,待播种后才知道生长不出,已无法挽回。杀虫的办法:①高温浸种法:把板栗种子放入60℃高温的水中浸泡10—15分钟,然后捞出摊开,虫可大部杀死。②药剂处理:将采回的板栗种子(一般是11月上甸进行),先放入80—90℃高温的水中浸泡1—2分钟,动作要迅速,浸泡时间最多不能超过5分钟。再用0.1％的甲胺磷溶液 Chestnut seed breeding by fruit, fruit moisture content is higher, no insecticidal seeds, in the temperature, humidity, place more than 20 days, about 30% of the seeds lost germination by insects, and the loss of seeds , The appearance is not easy to see, to be sown after we know that growth can not be recovered. Insecticidal approach: ① high temperature soaking method: the chestnut seeds into the water temperature of 60 ℃ soak for 10-15 minutes, then remove and spread out, the worm can kill most. ② Pharmacy Treatment: The recovered chestnut seeds (usually carried on the Austin in November), first into the 80-90 ℃ high temperature water for 1-2 minutes, the action should be prompt, soaking time can not exceed 5 minutes.
