笔者近两年来,在7～8月用稻草进行大床栽培试验,周期25天左右,生物学效率达35～40%.现将其技术要点介绍如下:(一)稻草浸水选无霉变的稻草,用清水浸泡24小时,让草秆充分浸透使组织软化.捞起后用清水冲洗2～3次,自然沥干至含水量70%左右进行堆料.(二)稻草预堆按干草72%、棉子壳20%、糖5%、石灰粉3%、磷酸二氢钾0.1%的配比,先调棉子壳含水量为65%左右,然后铺一层稻草加一层棉子壳、糖、石灰粉堆料,最后将磷酸二氢钾用适量水溶解浇在草
The author in the past two years, 7 to August with straw bed cultivation test, the cycle of 25 days, the biological efficiency of 35 to 40%. The technical points are as follows: (A) rice straw soaked without mildew Straw, soaked in water for 24 hours, so that grass stalks fully soaked to soften the organization. After picked up with water rinse 2 to 3 times, naturally drained to a moisture content of about 70% for stacking. %, Cottonseed shell 20%, sugar 5%, lime powder 3%, potassium dihydrogen phosphate 0.1% ratio, the first tune cotton seed hull water content of about 65%, and then shop a layer of straw plus a layer of cotton seed shell , Sugar, lime powder pile material, and finally potassium dihydrogen phosphate dissolved in water with the right amount of grass
