我场过去一直沿用湿砂埋藏法贮藏板栗,从11月下旬开始贮藏三个月左右,一般霉烂变质达15—20％。从1978年开始,我场在温砂埋藏的基础上,试用50％甲基托布津处理后再砂藏的方法,每年贮藏板栗约100斤,霉烂变质都在5％左右,栗实发芽率在98％以上,具体方法如下: 1.假藏(埋):板栗采收后1—2天内,用200倍50％甲基托布津液喷湿板栗,上下翻动,使之充分接触药液,喷后立即拌入三倍温砂,堆成2米宽、50—60厘米高的栗堆,上面盖一层温砂,以不见板栗为度,最外层盖塑料薄膜,以保持砂的湿度,如贮藏地过于干燥,地面应适当喷水。假藏后每 My field in the past has been used to store chestnut sand buried method, from late November to store about three months, the general rotten metamorphism of 15-20%. From 1978 onwards, based on the buried burial of warm sand, we tried the method of storing 50% thiophanate-methyl sand and then storing about 100 kg of chestnut every year. The rotten mildew was about 5% More than 98%, the specific methods are as follows: 1 false possession (buried): 1-2 days after chestnut harvest, 200 times 50% thiophanate methyl spray wet chestnut, flip up and down to make full access to the liquid spray Immediately after mixing into the warm sand three times, stacked into 2 meters wide, 50-60 cm tall chestnut heap, covered with a layer of warm sand, not to see the chestnut for the degree, the outermost plastic cover plastic film to keep the sand humidity, If the storage area is too dry, the ground should be properly sprinkler.
