娄底地区积极推广地膜覆盖栽培西瓜技术,今年夺得了大丰收,对照试验表明,采用地膜覆盖技术的要高产20％以上,取得了较好的经济效益。双峰县甘棠乡冷水村村民朱富强二弟兄各种八分田的西瓜,日照、雨水、品种完全一样,哥哥朱富强覆盖地膜,第一轮收西瓜1600多斤,而弟弟朱善强没有覆盖地膜,只收西瓜900多斤,比哥哥少收600多斤。采用地膜覆盖栽培西瓜,不仅能增产,而且能抗病虫害、抗旱,还能增加糖份,去除杂味。采用地膜覆盖栽培西瓜,主要有如下好处:一是提高地温、防寒保苗。西瓜地覆盖地膜,一般可提高地温2—4℃,晴天有时可提高10℃以上。同时,还可保持土壤疏松、湿润、雨天不会造成土壤过湿和板结。二是提早座果,提高单产增加收入。覆盖地膜的西瓜比没有覆盖地膜的要提早2～7天收获。三是减少病菌传播,起着综合防病防虫作用。西瓜发病的重要条件是 Loudi actively promote film mulching cultivation of watermelon technology, this year won the bumper harvest, the control trial showed that the use of plastic film mulching technology to yield more than 20%, and achieved good economic returns. Shuangfeng County, Kom Tong Township, cold water village villagers Zhu Fuqiang brothers eight watermelon, sunshine, rain, all the same, brother Zhu Fuqiang cover plastic film, the first round of watermelon received 1600 kilos, while his brother Zhu Shanqiang did not cover the film , Only received 900 kilos of watermelon, brother less than 600 kilos. Watermelon cultivation using mulching film, not only increase production, but also resistant to pests and diseases, drought, but also increase the sugar to remove miscellaneous taste. Watermelon cultivation using mulching, the main benefits are as follows: First, improve ground temperature, cold seedlings. Watermelon to cover the plastic film, generally can increase the ground temperature 2-4 ℃, sunny sometimes can increase 10 ℃ above. At the same time, but also to keep the soil loose, moist, rainy days will not cause soil moisture and compaction. Second, early fruit, improve yields increase income. Watermelon covering the film than did not cover the film to be harvested 2 to 7 days earlier. Third, reduce the spread of germs, play a comprehensive anti-disease pest control. An important condition for the incidence of watermelon is
