为了观察移栽棉的增产效果及其对田间水分条件的要求,1974～75年在大田中固定地段,与直播棉进行比较。现简结如下: 一、试验情况及气候条件用地8～10亩,前茬玉米,冬前深翻(1～1.2尺深),结合亩施土粪1.2万斤。春季结合浅耕亩施油渣60～100斤、过磷酸钙100斤。播前蓄水灌溉,耙耱保墒。供试品种:1974年陕棉401,3月18日育苗,4月23日移栽;1975年鄂岱棉,3月20日
In order to observe the yield-increasing effect of transplanting cotton and its requirement on the field moisture conditions, the fixed field in 1974-75 was compared with live cotton. Now summarized as follows: First, the test conditions and climatic conditions 8 to 10 acres of land, before the crop of corn, deep winter before turning (1 ~ 1.2 feet deep), combined with Mushi soil dung 12,000 pounds. Combined with shallow tillage in spring spring oil residue 60 to 100 pounds, superphosphate 100 pounds. Pre-sowing irrigation, rake 耱 soil moisture. Test varieties: Shaanxi and cotton in 1974 401, March 18 nursery, April 23 transplanting; E Tei cotton in 1975, March 20
