我县北部山区系大别山尾余脉,海拔200～600m的山区可耕面积约4万亩,传统的耕作制度为“芋、稻”二茬轮作,即春节前后栽一茬洋芋(马铃薯)至翌年端午节左右收起后当即抢播一茬中季稻谷,中秋节左右收割.尔后因山区气候渐寒,一直空闲至立春.为此,我们试拟利用中秋节后至春节的4个月空闲耕地栽培一茬平菇.经1988、1989两年的重复试验,亩投料(棉子壳)5000kg生物效率均达80%以上,亩获利3000元.不仅如此,经出菇后的下床废料,在栽洋芋前几天翻耕作底肥,洋芋明显增产.
The mountainous area in the northern part of the county is the tail vein of the Dabie Mountains, and the cultivated area in the mountains with an elevation of 200-600m is about 40,000 mu. The traditional farming system is “two-crop rotation” of “taro and rice”, that is, planting potato (potato) before and after the Spring Festival, After the Dragon Boat Festival the following year to close immediately after the grab a crop of mid-season paddy, harvest around the Mid-Autumn Festival .. Later because of the mountainous climate is cold, has been idle until the beginning of spring .To this end, we try to use the Mid-Autumn Festival to the Spring Festival 4 months Idle cultivated cultivation of stubble mushrooms .1988, 1989 two years of repeated tests, acres of material (cotton seed hull) 5000kg biological efficiency reached more than 80%, profit of 3,000 acres profit. Not only that, after getting out of bed after fruiting Scrap, a few days before planting potatoes as a base fertilizer, potato yield significantly.
