为了进一步探讨马铃薯全膜高垄侧播与糯玉米带状套种增产增收效果,为高产高效综合配套技术在甘肃省天水市秦州区高寒冷凉山区推广应用提供理论依据。通过采用马铃薯全膜高垄侧播(单种)、糯玉米全膜双垄沟播(单种)和马铃薯全膜高垄侧播与沟内单行点播糯玉米(带状套种)三种种植方式重复三次进行试验,其结果表明:马铃薯(克新2号)单种产量为31 290kg/hm~2,纯收入22 860元/hm~2。糯玉米(天润糯1号)单种产量为18 829.5kg/hm~2,纯收入17 617.2元/hm~2。两种作物套种克新2号产量为33 103.5kg/hm~2,纯收入25 580.3元/hm~2,天润糯1号产量为18 430.5kg/hm~2,纯收入26 488.8元/hm~2。
In order to further explore the effect of yield increasing and yield increasing on the side-sowing of potato with high ridge and waxy maize, and providing the theoretical basis for the popularization and application of high yield and high efficiency integrated supporting technology in cold and cold mountainous areas of Qinzhou District, Tianshui City, Gansu Province. The experiment was carried out by using three kinds of planting modes: potato all-film high ridge side sowing (single species), waxy maize whole film double ridge furrow sowing (single species) and potato whole film high ridge sowing and single row sowing waxy corn The results showed that the single yield of potato (Kexin 2) was 31 290kg / hm ~ 2 and the net income was 22 860yuan / hm ~ 2. The single yield of waxy corn (Tianrunnuo No. 1) was 18 829.5kg / hm ~ 2, and the net income was 17 617.2 yuan / hm ~ 2. The yield of Kexin 2 was 33 103.5kg / hm ~ 2, the net income was 25 580.3yuan / hm ~ 2, the output of Tianrunuo 1 was 18 430.5kg / hm ~ 2 and the net income was 26 488.8yuan / hm ~ 2.
