摘要
研究了黑色液膜喷施量对冬小麦土壤墒情及产量的影响。结果表明：随着液膜喷施量的增加,土壤保墒保温效果比较明显;冬小麦可提前1～2 d出苗,出苗整齐,冬前分蘖和干物质积累较多,增产作用显著。综合各处理产量、生育指标和经济效益分析,喷施液膜量以600 kg/hm^2效果最好。
The results of Film of black spray volume of soil moisture and winter wheat yield showed ： With the film spraying increase, in the amount of soil moisture-retaining insulation relatively effective, advanced 1-2 days emergence, Emergence neatly, before winter tillering and dry matter accumulation of more, output significantly. Comprehensive handling of the production, reproduction and economic analysis, we think that spray liquid membrane volume 600 kg/hm^2 is the best results.
