在各级党委的正确领导下,在农业学大寨的群众运动中,鄂北岗地旧貌变新颜,已由过去水利设施少、单一旱作、畜力浅耕、不种绿肥,发展到今日的堰库成群,渠系成网,水旱作物并举,机畜深耕,大种绿肥,从而提高了土壤肥力和作物产量。在这些翻天覆地的变革中,我们以襄郜三队为基地(耕地面积915亩),和贫下中农相结合,对鄂北岗地提高土壤肥力的关键技术措施进行了生产和科研实践。 鄂北岗地位于我省西北部,年平均温度 Under the correct leadership of the party committees at all levels and in the mass movement of learning from Dazhai in agriculture, the old posts in northern Hubei Province changed their colors from the past with less water conservancy facilities, single dry cultivation, shallow plowing with animal power and no green manure to today Of the weir reservoirs, canal networks, water and rain crops simultaneously, animal plowing, large green manures, thereby increasing soil fertility and crop yield. In these earth-shaking changes, we have made production and scientific research on the key technical measures to improve soil fertility in Northern Hubei based on the cooperation of Xiang Tri-team (915 acres of arable land) and poor and middle peasants. North Hubei Kong is located in the northwestern part of our province, the annual average temperature
