不同栽培调控措施对马铃薯产量及效益的影响
Effects of Different Cultivation and Regulation Modes on Potato Yield and Benefit
【摘要】 通过播期、密度及栽培试验,分析不同播期、密度及栽培调控措施对马铃薯产量及效益的影响。结果表明,5月5日结合3 200株/667m~2播种,能够提高马铃薯产量和经济效益,2年平均产量达到1 517.5 kg/667m~2,产值为1 521.8元/667m~2;覆膜栽培方式平均产量为1 830.6 kg/667m~2,产值为1 831.7元/667m~2,较露地栽培方式提高270.6元/667m~2;马铃薯套种萝卜产值达到1 663.2元/667m~2,较不套种模式提高263.9元/667m~2。说明5月5日覆膜播种配套间套作栽培技术在甘肃省陇东地区能够促进马铃薯产量及经济效益的形成。
【Abstract】 The cultivation mode of sowing date, planting density, and cultivation and regulation modes on potato yield and benefit were investigated in this study. The sowing date of May 5 and the planting density of 3 200 plants/667m~2 improved potato yield and economic benefit, with the average yield reaching 1 517.5 kg/667m~2 and output value being 1 521.8 Yuan/667m~2. The measure of film mulching had an average yield of 1 830.6 kg/667m~2, and output value reached to 1 831.7 Yuan/667m~2, which increased 270.6 Yuan/667m~2 compared with that of open field. Potato intercropped with radish had the highest economic benefit, with an average of 1 663.2 Yuan/667m~2, increasing 263.9 Yuan/667m~2 compared with the control. The results suggest that sowing potato on May 5 in combination with film mulching and intercropping cultivation techniques could promote the formation of potato yield and economic benefit in the Longdong area of Gansu Province.
