江苏省北部淮阴专区,最近二年才开始植棉。一般对棉花栽培技术,尚感生疏。尤其缺乏播前种子处理的技术,因而常引起出苗迟、缺苗多的现象,如本场1951年采用群众习惯用的冷水浸种8小时(一夜)方法处理棉籽,结果因天雨耽误了播种,棉籽在家里出了芽,不能再用。1952年未经处理就播种,结果迟达20天才出苗,造成严重的缺苗和迟熟现象,因此,保证早出苗、不缺苗已是本地区棉花生产上的一大问题。1953年,本场在这方面作了对比试验,结果证明以“晒种——温汤浸种”法处理的棉籽,不但提早出
Huaiyin area in northern Jiangsu Province, the last two years began to plant cotton. General cotton cultivation techniques, still feeling unfamiliar. In particular, the lack of pre-sowing seed treatment technology, which often caused by late emergence, lack of seedlings and more phenomena, such as the market in 1951 with the public habit of using cold water soaking 8 hours (overnight) method of treatment of cottonseed, the result of delayed rain sown, Cottonseed sprouts out of the house and can not be used anymore. Sown in 1952 without treatment, the result of as late as 20 days before emergence, resulting in serious lack of seedlings and late maturity, therefore, to ensure early emergence, no shortage of seedlings is the cotton production in the region a major problem. In 1953, the field made a comparative test in this regard, the results show that “drying kind - warm soup soaking seed” method of treatment of cottonseed, not only early out
