我区常年栽种200多万亩甘薯,其中春薯120多万亩。过去,春薯采用火炕育苗,全区每年需用煤8,000多万斤,约150多万元。且常因煤源缺乏、烧柴不足造成秧苗数量不够或推迟栽种时间,对春薯产量影响很大。有些社队采用塑料薄膜肥土育苗,解决了煤和柴的问题。但出苗少、出苗晚。针对上述问题,两年来,我们驻郑庄大队基点的同志和贫下中农一起进行了用土面增温剂育甘薯苗的试验,取得了一些成绩。土面增温剂是一种农田化学覆盖物。目前我区各社都能自己制造,用在甘薯育苗上,具有出苗齐、苗 My area planted more than 200 acres of sweet potato, of which more than 120 acres of spring potato. In the past, sweet potato nursery with kang, the region need more than 8,000 kilograms of coal each year, about 150 million. And often because of the lack of coal, firewood caused by lack of enough or delayed the number of seedlings planted, a significant impact on the yield of sweet potato. Some communes and teams use plastic film fertilizer soil nursery, to solve the problem of coal and wood. However, less emergence, emergence late. In response to the above issue, two years ago, comrades from the base of Zhengzhuang Brigade and poor peasants and peasants have conducted experiments on raising sweet potato seedlings with soil warming agents. Some achievements have been made. Soil warming agent is a farm chemical cover. At present, each district and I community can create their own, used in sweet potato nursery, with the emergence of Qi, Miao
