棉花新品系“3292”具有高产优质、后劲足、不早衰、抗逆性强、适应性广等优点。1983年在荆州地区种植面积达30万亩以上。该品系特点是种子较大,出苗整齐,根系发达,苗势较强,叶较大,叶色较淡,营养物质运转较快。但是,苗期地上部分茎叶生长比较缓慢,进入盛蕾后,生长速度才明显加快。据1982年分阶段苗高调查,6月15日以前,主茎平均日生长量为0.37厘米,6月16日至7月15日,平均日生长量1.54厘米,7月16日至31日,日生长量达2.91厘米。苗期由于生长缓慢而对养分需要较少。据测定,苗期吸收的氮素只占全生育期吸收总量的5％左右,磷、钾素的吸收各占3％
New cotton line “3292” with high yield and quality, stamina enough, not premature, strong resistance, wide adaptability and so on. In 1983 in Jingzhou area planted area of 300000 mus of above. The characteristics of the line is a large seed, emergence neat, developed root system, strong seedling, leaf larger, leaf color lighter, faster nutrition. However, the growth of shoots and leaves of shoots in seedling stage was relatively slow. After entering Shenglei, the growth rate was significantly accelerated. According to the 1982 survey of seedling height in stages, before June 15, the average daily growth of the main stem was 0.37 cm. From June 16 to July 15, the average daily growth was 1.54 cm. From July 16 to July 31, Daily growth of 2.91 cm. Seedling needs less nutrients due to slow growth. It is determined that the nitrogen absorbed in seedlings only accounts for about 5% of the total growth during the absorption, phosphorus and potassium absorption of 3%
