摘要
以“苏玉 9号”为试材 ,研究了多熟制春玉米覆膜移栽的生态效应、植株生长特点及其对产量的影响。结果表明 :覆膜移栽可改善土壤的生态环境 ,提高土壤温度、降低土壤容重、增加土壤的含水量 ;促进玉米的生长发育 ;提早成熟 ,增加产量。
Su Yu 9 maize variety was selected to analyze the effects of spring maize transplanting with plastic film mulching on soil ecological effect, plant growth characteristics and the yield The results showed that transplanting spring maize with plastic film mulching could improve the ecological environment of soil , increase soil temperatures and soil water contents, decrease the soil bulk weight,promote the growth and maturation of maize, and increase the output
