玉米‖马铃薯抗旱栽培土壤含水量及产量效益研究
Effect of maize‖potato intercropping on topsoil moisture and yield benefits
摘要
Abstract
The field experiment was conducted to investigate the effect of maize‖potato intercropping on drought re-sistance in the Agricultural Technology Demonstration Base of Xuanwei city in 2014.The treatments include:T1,maize+ ditching + polythene mulch intercropping with potato;T2,maize + pitting + polythene mulch intercropping with potato;T3,maize + polythene mulch intercropping with potato;T4,maize monoculture with polythene;T5,potato monoculture.The results showed that mean soil moisture of treatment T1and T2in maize field were higher than that of treatment T4,as increased by 28.32% in 0~7.6 cm soil layer and 28.12% in 0~20 cm soil layer respectively.Soil moisture of treatment T1and T2in potato field were increased by 23.52% in 0~7.6 cm soil layer and 12.78% in 0~20 cm soil layer compared with treatment T5.Treatment T1and T2significantly increased the yield of maize and land e-quivalent ratio(LER)than treatment T3,the LER of T2(LER=1.20)was 10.52% higher than T3.关键词
