本文通过对早熟陆地棉新陆早8号3年单株定点观察结果的分析，探索其生育规律及栽培技术。新陆早8号全生育期125天左右，所需≥10℃有效积温1691．2～1801．4℃，4月中旬播种，6月初现蕾，6月下旬开花，花铃期60．1～67.0天，单株成铃率35％，第1果节成铃率65％，内围中下部第1果节为优质结铃部位,8月下旬吐絮，吐絮畅快集中；生殖器官生育节奏表现为同位快于邻位，内围快于外围，吐絮快于开花，开花稍快于现蕾，落铃多于落蕾。新陆早8号最佳播期地膜棉4月10～20日，每666.7m2（旧制1亩，下同）留苗1.2～1．4万株，全层施肥，追施花铃肥，适期灌水3～4次，全生育期化调2～3次，中后期结合化调或治虫喷施叶面肥。7月中旬打顶，留果枝8～10台，株高控制在55～56cm为宜。
In this paper, we analyzed the fixed-point observation results of the early-mature upland cotton Xinluzao 8 and 3 years to explore its fertility and cultivation techniques. Xinluzao 8 full growth period of about 125 days, the required ≥ 10 ℃ effective accumulated temperature 1691. 2 ~ 1801. 4 ℃, sowing in mid-April, early June bud, flowering in late June, flowering period 60.1 ~ 67.0 days, boll rate per plant was 35%, the boll rate was 65% in the first fruit section, the first fruit node in the middle and lower middle section was the high quality boll site, For the same position faster than the adjacent position, faster than the outer periphery, boll flow faster than flowering, flowering slightly faster than budding, falling off more than falling buds. Xinluzao No. 8 best sowing date cotton film April 10 to 20, 666.7m2 (1 mu of old, the same below) 1.2 to 1.4 million seedlings, full-layer fertilizer, topdressing boll fertilizer, irrigation 3 to 4 times, the whole growth period of tune 2 to 3 times, combined with the transfer or pest control foliar fertilizer. Topped in mid-July, leaving fruiting branches 8 to 10 units, height control in 55 ~ 56cm is appropriate.
