板栗常因栗实象等害虫为害,或因贮藏条件不当引起大量腐烂,损失严重。过去,采用冷藏、C_0~(60)r辐射处理办法虽好,但因设备昂贵,难以推广。用二硫化碳、溴甲烷熏蒸,又不安全。因此,选用对板栗贮藏性无损害的磷化铝熏蒸剂进行杀虫试验,并进一步探讨板栗对贮藏保鲜的适宜条件。 材料和方法 一、不同药剂处理的贮藏试验 1984年供试材料是成熟度较差的中、晚熟混合品种,试验数量为380公斤。经过三种药剂熏蒸处理,果内幼虫全部杀死。药剂规格:52％磷化铝,每片(3克重)含有效
Chestnut chestnut instar often due to other pests, or due to improper storage conditions caused a large number of decay, serious loss. In the past, the use of refrigeration, C_0 ~ (60) r radiation treatment is good, but because of expensive equipment, it is difficult to promote. With carbon disulfide, methyl bromide fumigation, not safe. Therefore, the selection of chestnut storage-free aluminum phosphide fumigation insecticide test, and to further explore chestnut suitable storage conditions. Materials and methods First, the storage of different pharmaceutical treatment test 1984 test material is less mature, late-maturing hybrid varieties, the test number of 380 kg. After three agents fumigation, fruit larvae all killed. Pharmacy Specifications: 52% aluminum phosphide, each tablet (3 grams) containing effective
