华中地区,秋季多雨,影响棉花成熟期延迟,致部分棉籽不能充分成熟,发芽率较低,尤其是岱字棉15号此种现象更为普遍;根据苏联先进经验:晒种可提高棉籽发芽率,提早成熟期;本所1954年试验:室内发芽及苗期观察结果,以晒种四、五十小时效果较好;(该试验7月中旬为积水淹没,无後期结果。)为继续探寻晒种处理的具体技术措施及其对岱字棉15号的生育影响,以便确定晒种在本地区的使用价值,提供推广应用的参考,特又於1955年进行本试验。
In central China, rainy autumn, affecting the delay of cotton maturity, resulting in part of the cottonseed can not fully mature, germination rate is low, especially Dai word cotton 15 this phenomenon is more common; advanced Soviet experience: drying seed germination rate can improve cottonseed , Early maturity; the 1954 test: the indoor germination and seedling observation results to sunburn four or fifty hours better; (the test in mid-July for the flooding, no later results.) To continue to explore The specific technical measures of drying and processing and their impact on the Dai Zi Cotton 15 in order to determine the sunburn in the use value of the region to provide a reference for the promotion and application, especially in 1955 for the test.
