| 摘 要： | 在半干旱地区玉米采用麻地膜覆盖栽培与普通地膜覆盖栽培、常规栽培进行了田间应用效果试验,研究了麻地膜覆盖栽培对土壤理化性状、土壤温度、土壤持水量、玉米生长及产量等的影响。结果表明,麻地膜覆盖栽培比常规栽培生育进程加快,株高和叶面积系数增加,根干重减少,水分利用效率增加,产量增加8.42%。麻地膜覆盖栽培经济效益低于常规栽培。

| Abstract: | The field experiment on hemp-plastic mulching cultivation,normal plastic mulching cultivation and usual cultivation of maize in semi-arid area was carried out.Through the experiment,effect of hemp-plas- tic mulching cultivation to soil physical and chemical properties,soil humidity,soil water content,growth and yield of maize was studied.The results showed that cultivating maize with hemp-plastic mulching could hasten the growth stage,increase maize plant height and leaf area index,decrease the dry weight of maize root,in- crease water utilization efficiency and increase maize yield by 8.42% compared with usual cultivation.However, the economic profit for hemp-plastic mulching maize was lower than that of usual cultivation. |
