全膜双垄沟播蚕豆套种板蓝根是甘肃省临洮县农业技术推广部门在推广旱作技术过程中,经过试验示范筛选出的一项高效栽培技术模式。该模式规避了当地干旱少雨不利出苗,秋季雨水过多造成沤根、烂根,与小麦等密植作物套种共生期长不利于产量形成等缺陷,进一步挖掘了耕地增产潜力,提高了种植效益,增加了农民收入。该模式2014年蚕豆平均亩产340 kg,板蓝根平均亩产根量390 kg,合计亩收入在2 500元以上,经济效益较好,当地农民乐
Full film double furrow sowing broad bean intercropping Banlangen is Linqu County, Gansu Province agricultural extension unit in the promotion of dry farming technology, after screening through the demonstration of an efficient cultivation technology model. This model avoids the disadvantage of unfavorable emergence of drought and rainfall in the local area and the prolonged symbiotic growth of dense root crops like rotten roots, rotten roots and wheat, which is not conducive to the yield formation and other defects in the autumn. It further excavated the yield potential of cultivated land and increased the planting efficiency and increased Farmers income. In this model, the average yield of Vicia faba in 2014 was 340 kg, and the average yield of Radix isatis was 390 kg. The total mu income was over 2 500 yuan, and the economic benefit was better.
