河北省平泉县西坝乡无霜期为132天,年平均气温7.1℃,冻土层1.1米,在这样的环境条件下,可以实现周年生产。该乡二道河子村农民姚振平利用0.18亩海城式日光温室大棚,春节前生产芹菜、蒜苗、韭菜350多公斤,翌春生产黄瓜600多公斤。总计纯收入1300多元,他的做法是: 一、改海城式日光温室大棚前坡有支柱单层复盖为前坡无支柱双复盖这种大棚扩大了采光面,保温性能良好,一般比单层复盖提高温度3—5℃,因此为早育苗、早定植、提早上市打下了基础。实现了黄瓜1月11日育苗,2月17日定植,3月21日上市,产量产值上市期均占全县之首。为增加收入合理安排下茬,周年生产提供了条件(见图)。
Xiba Township, Pingquan County, Hebei Province has an frost-free period of 132 days with an annual average temperature of 7.1 ℃ and a frozen soil layer of 1.1 meters. Under such environmental conditions, annual production can be realized. The township two farmers Yao Zhenping Haizhu 0.18 acres of trees using light greenhouses, before the Spring Festival celery, garlic, leeks more than 350 kilograms, cucumber production next spring more than 600 kilograms. A total net income of more than 1300 yuan, his approach is: First, to change Haicheng greenhouse before the slope of a greenhouse with a single layer of cover for the front slope without strut double cover This greenhouses to expand the lighting surface, good insulation properties, the general ratio Single-layer coverage to raise the temperature of 3-5 ℃, so early nursery, early colonization, early listing laid the foundation. To achieve the cucumber January 11 nursery, February 17 colonization, March 21 listing, production and output value of the listing period accounted for the first in the county. In order to increase revenue reasonable arrangements for the next crop, the annual production of the conditions provided (see photo).
