一、技术背景丘陵旱地套作小麦种植面积占我省小麦种植面积的绝大部分,然而,随着该区域农村主要劳动力的大量转移,农业生产劳动力短缺,人工劳动力成本大幅度增加,以往的精耕细作已不再适应当前农村劳动力结构现状。小春生产出现滑坡,种植粗放,套作小麦有效穗常不足10万/亩,亩产在200kg/亩左右徘徊,个别地方甚至出现小春这一季耕地撂荒的现象。 First, the technical background Hilly dryland intercropping wheat acreage accounted for most of the province’s wheat acreage, however, with the transfer of major rural labor force in the region, the shortage of agricultural production labor, labor costs increased significantly, the previous intensive work No longer adapt to the current rural labor force status quo. In the early days of the Spring, there were landslides and extensive planting. The earliest effective per hectare of wheat was often less than 100,000 mu, and the mu production was hovering around 200 kg / mu. In some places, there was even a shortage of cultivated land in the spring of this year.
