笔者在几年的栽培和辅导生产中,逐步摸索出一种简便易行的预处理陈旧棉籽壳的办法。现介绍如下: 第一步是晒料。在播种前一个星期,将棉子壳在太阳底下曝晒3—4天,晒时可掺进1％的石灰粉。晒后趁热堆起来,并覆盖薄膜放置2—3天。这样可以杀死部分杂菌和虫卵。第二步是堆制发酵。具体作法是:料晒后按每100公斤干料加进石灰粉2％(如晒料时已加石灰,这时可适当少一些)、多菌灵0.2％、料水比为1:1.2～1.4,充分拌匀后堆积起来,堆宽1.5米,高1.2米,长不限,顶部呈龟背型,堆好后四周拍紧,料堆 The author in a few years of cultivation and counseling production, and gradually find out a simple and easy way to deal with the old cotton seed hulls. Now introduced as follows: The first step is drying material. One week before sowing, the cotton seed shell is exposed to the sun for 3-4 days, and the sun can be mixed with 1% lime powder. After the sun hot piled up, and cover the film placed 2-3 days. This can kill some bacteria and eggs. The second step is to stack fermentation. Specific approach is: After the sun drying material per 100 kg of lime powder added 2% (such as sunburn has been added lime, then less appropriate), carbendazim 0.2%, water ratio of 1: 1.2 ~ 1.4, fully mixed and stacked up, heap width of 1.5 meters, 1.2 meters high, not limited to the length of the top Turtle-type, four weeks after the heap tight, material pile
