【摘要】 为提高红肉火龙果间种马铃薯经济效益,研究红肉火龙果间种马铃薯中不同栽培模式对马铃薯产量、商品薯率、火龙果产量、中心可溶性固形物含量、总产值和纯收入的影响。结果表明:与火龙果桂香红间种的马铃薯品种兴佳2号产量达36 139.5 kg/hm~2,商品薯率达97.3%;桂香红产量达35 586 kg/hm~2,中心可溶性固形物含量达20%;与桂香红纯种相比,总产值增加52.7%,纯收入增加109.7%,土地当量比为1.13。更多还原

【Abstract】 In order to improve the economic benefit of red flesh pitaya intercropping with potato, the effects of different cropping patterns on potato yield, marketable tuber ratio, pitaya yield, central soluble solid content, total output value, and net income during red flesh pitaya intercropping with potato were studied. The results showed that the total output value was the highest and the economic benefit was the best in red flesh pitaya Guixianghong intercropping with potato variety Xingjia No.2. The yield of Xingjia No.2 reached 36 139.5 kg/hm~2 and marketable tuber ratio reached 97.3%, while the yield of Guixianghong was 35 586 kg/hm~2 and central soluble solid content was 20%. Compared with Guixianghong sole cropping, the total output value of Guixianghong intercroppong with Xingjia No.2 increased 52.7%, net income increased 109.7%, and land equivalent ratio reached 1.13.更多还原
