地面塑料薄膜覆盖是农作物、园艺作物栽培采用的一项有效技术措施。根据云南昆明地区的气候情况,春季正处于干旱季节,日照强,常风多,蒸发量大,空气干燥。这对柑桔的萌发、开花、座果、落果和树体及幼果的生长发育有不同程度的影响。1983～1985年我们在昆明市富民县何光营2～7年生温州蜜柑桔园,先后共进行了一千三百多株地膜覆盖试验,获得了较好的效应。试验证明,不仅是提高土壤温度,减少土壤水分蒸发,且对柑桔幼树的座果率,成果率有提高,相应增加了产量,对新梢的抽发,树体的生长均有好的效应。
Plastic film covering the ground is crop, horticultural crop cultivation adopted by an effective technical measure. According to the climatic conditions in Kunming, Yunnan Province, the spring is in the dry season with strong sunshine, frequent winds, large evaporation and air-drying. This on the citrus germination, flowering, fruit, fruit and tree and young fruit growth and development have varying degrees of impact. 1983 ~ 1985 We Kunming Fumin He Guangying 2 to 7-year-old Wenzhou Citrus Orange Park, has conducted a total of more than 1,300 film mulching test, and achieved good results. Experiments show that not only to improve the soil temperature and reduce soil water evaporation, and the fruit-bearing rate of citrus young trees, the results have increased, a corresponding increase in yield, the shoot of the shoots are good growth of the tree body effect.
