为解决因受山谷寒风影响而引起的烂秧问题,我们设计了牛粪草酿热温床薄膜棚温室育秧,经多次试用和推广,效果好,受到群众欢迎。这一育秧法是利用牛粪草发酵过程中释放出来的热量提高薄膜棚温室的温度,不用燃料,节省烧火用工,大大降低温室育秧成本,还能育出好秧。我们于3月26日做的牛粪草温床,3月30日,床温升到 In order to solve the problem of rotting seedlings caused by the cold wind of the valley, we designed a seedling raising greenhouse with cow dung topping hot film greenhouse. After many trials and promotion, the effect was good and welcomed by the masses. This method of raising seedlings is to utilize the heat released during the cow manure fermentation to raise the temperature of the greenhouse of the film greenhouse without fuels, to save the cost of burning firewood, to greatly reduce the cost of greenhouse seedling cultivation, and to cultivate good seedlings. The cow dung hotbed we made on March 26, March 30, the bed temperature rose
