摘要
1985—1988年,在嫩江农科所内对玉米覆膜栽培和露地栽培采用对比法,通过小区和盆栽试验研究的结果表明,地膜覆盖具有保墒、蓄水、调水、省水及改善土壤生态条件和理此性质,增强土壤蓄水能力,充分利用自然降水,促进玉米根系及地上部的生长发育,提高降水有效利用率的作用。玉米地膜覆盖栽培增产幅度大、经济效益高,适应范围广,在旱地玉米生产中具有广阔的发展前景。
The comparitive experiment of maize cultivation with plastic film coverand in the open field was conducted in Nenjiang Institute in 1985-1988.Theresults obtained through plots and pot cultivation showed that maize cultivatedwith plastic film cover has remarkable function to preserve moisture,retainwater,regulate water and save water,improve soil ecological conditions andphysical and chemical properties,increase soil ability to store water,makefull use of natural rainfall water,promote the development of maize root systemand the ground parts and raise water use efficiency.Maize cultivated withplastic film cover has a yield increase by a wide margin with a better economicreturn.Also,maize cultivated with plastic cover has a wide adaptable rangeand holds great potential for maize cultivation in rainfed lands.
