超级长绒棉,指绒长一又八分之三时以上,纤维细,强度高,可纺60支至200支细纱,最高可达400支,为高级棉纺织品的主要原料;也是汽车工业中纺帘子布的重要原料。过去在长江流域试种这些高品质棉种的问题,是成熟迟、产量低。1954—1958年,5年来,长绒三号在南京试种,每亩平均产籽棉117斤,霜前花占55%。苏联的埃及棉类型以及埃及的长绒棉品种,在南京试种的生育情况也不比长绒三号好,角斑病重,产量更低,品质也不如长绒三号细长色白。长绒三号的皮棉产量,在南京种植一般仅为岱字棉的四分之一至三分之一,因此,长绒三号的成熟期与产量,没有显著改进以前,在长江流域大面积栽培,是不够条件的。现在
Super long-staple cotton, finger length of one and more than three o’clock, fine fibers, high strength, spinning 60 to 200 spun, up to 400, the main raw material for high-grade cotton textiles; also the automotive industry An important raw material for spinning cord fabric. In the past, the problem of testing these high-quality cotton varieties in the Yangtze River valley was delayed and low in yield. In 1954-1958, over the past five years, Longrong No.3 has been planted in Nanjing with an average yield of 117 pounds of seed cotton per acre and a pre-frost flower of 55%. The Egyptian cotton type in the Soviet Union and the Egyptian long-staple cotton varieties are not better than the cashmere varieties grown in Nanjing. The angular leaf spot is severe and the output is even lower. The quality is not as good as that of the slender white color of Longmao No.3. Lint three lint yield, planted in Nanjing is generally only one-fourth to one-third of Dai cotton, therefore, the maturity and yield of plum three no significant improvement Previously, in the Yangtze River area Cultivation is not enough conditions. just now
