一、早收灭茬整地:小麦收后复种洋芋,一季两作,土壤养分消耗量大,两作之间又无休闲养地时间,因此要在时间上下功夫,力争一个“早”字。小麦在蜡熟末期就立即收获,收获后堆垛晾晒待碾,为复种洋芋抢时间。麦收后立即灭茬深耕整地、耕翻、耙耱连续操作,使土壤达到松、平、软、绵的要求。 二、选用良种:麦后复种应选用植株生长健壮,块茎膨大快,养分积 First, stubble stubble early Land preparation: Wheat after the reclamation of potato, a quarter for two, soil nutrient consumption, there is no leisure time between the two for the time, so in time to work hard and strive for an “early” word. The wheat is harvested immediately at the end of the wax ripening period, and the stacks are dried to be grind after harvest to grab the time for multiple breeding. Immediately after harvest wheat stubble plowing plowing and plowing, plowing, raking 耱 continuous operation, so that soil to pine, flat, soft, cotton requirements. Second, the selection of elite: After the wheat should be selected plant growth robust, tuber expansion fast, nutrient accumulation
