麦后直播棉花由于晚播迟熟,常使产量不稳定,品质受影响,为了达到早熟、高产、优质的要求,我们1977年在校内(武昌)校外(天门)进行了高密度丰产栽培试验和品种、密度、施肥量三因素,三水平正交试验。丰产试验(天门)面积一亩,土质油沙(沙性重),前作小麦,品种早红,亩产550斤。棉花供试品种为74—101优系,实际密度12500株、亩产126.6斤皮棉,10月25日前收花量占
Post-wheat live broadcast of cotton due to delayed late maturing, often yield instability, the quality of affected, in order to achieve early maturity, high yield, high quality requirements, we in 1977 (Wuchang) outside the school (Tianmen) conducted high-density and high yield cultivation trials and Variety, density, fertilizer three factors, three levels of orthogonal test. High yield test (Tianmen) an area of ?? acre, soil oil sand (sand weight), before the wheat, red early varieties, yield 550 pounds. Cotton varieties tested 74-101 excellent lines, the actual density of 12,500, 126.6 kg of lint per mu, before October 25 revenue accounted for
