露天散装粮堆密闭储藏是露天储粮的一个新项目。近年来粮食不断丰收,露天储粮成了解决仓容不足的主要储粮方法。露天存粮由于受外界温、湿度的影响较大,易受害虫的感染,易遭鼠雀的危害。露天粮难存的矛盾十分突出。为了解决露天存粮难的问题,在省、地粮食局的安排下,我们对露天粮堆进行了薄膜密闭储粮试验。经过一年的试验,已取得初步成效。现将试验情况报告如下:一、试验原理:露天散装粮堆密闭是借薄膜密闭防止虫害的感染;利用糠壳的隔热性好,保暖性强,传热性差的特点,防止上层粮食结露。1.塑料薄膜密闭解决虫害感染:
Open-air bulk grain storage Closed storage is a new project of grain storage. In recent years, continuous harvest of grain, open grain storage grain storage capacity has become the main method of grain storage inadequate. Open-air food due to the outside world due to temperature and humidity greater susceptibility to pest infections, susceptible to rat harm. The contradiction of open food is very prominent. In order to solve the problem of storing grain in open air, under the arrangement of the provincial and prefectural grain bureaus, we conducted a film-sealed grain storage test on the open-air grain piles. After a year of testing, preliminary results have been achieved. Now the test report is as follows: First, the test principle: open bulk bulk reactor is closed by film to prevent pest infection; the use of bran shell insulation good, warm and strong, poor heat transfer characteristics to prevent the upper grain dew . 1. plastic film closed solution pest infection:
