一、特征特性新彩棉2号适应南北疆早熟棉区种植,苗期出苗快而整齐,生长稳健;花铃期脱落少,铃期发育快,结铃集中;田间对枯萎病有一定抗性,较耐旱,后期有不早衰的特点。现蕾、开花集中,结铃性强,全株上、中、下部棉铃分布均匀。收获株数1.1~1.46万株/667米~2,单株成铃6~8个,衣分33%~35%,铃重5克,霜前花比例在90%~95%,高产、稳产,增产潜力较大。据农业部棉花品质监督检验测试中心 HVI900检测结果,纤维品质2.5%的跨长为29.43毫米,比强21.86cn/tex,马克隆值3.4,整齐度48.13%,伸长率为7.6%。二、栽培技术生育期127天左右,4月5~25日播种;苗期4月15~5月1日;现蕾期5月18~30日;开花期6月20~7月1日;吐絮期8月20~25日。三、播前准备
First, the characteristic characteristics XinCotton 2 to adapt to the cotton growing areas of northern and southern Xinjiang cotton planting, fast and neat emergence of seedlings, growth and stability; less flower shedding period, rapid development of bolls, bolls concentrated; field have a certain resistance to blight Sexual, more drought-resistant, there is no premature decline in the late characteristics. Budding, flowering, boll and strong, the whole plant, in the lower part of the cotton boll evenly distributed. The number of harvested plants was 1.1-14600 plants / 667m2, with 6-8 bolls per plant, 33-35% bolls, 5 grams boll weight, 90% -95% Increased yield potential. According to the result of HVI900 test by Cotton Quality Supervision and Testing Center of Ministry of Agriculture, the span length of 2.5% of the fiber quality is 29.43 mm, the specific strength is 21.86 cn / tex, the micronaire value is 3.4, the uniformity is 48.13% and the elongation is 7.6%. Second, the cultivation of 127 days growth period, April 5 to 25 sowing; seedling April 15 ~ May 1; budding May 18 to 30; flowering June 20 ~ July 1; Bolting flocculent August 20 ~ 25. Third, before sowing
