本文根据雹灾棉不同受害程度，选择了几种受害类型，对棉花生育状况进行了调查，结果表明，以“有头有叶”类型恢复生长最快，一般灾后１０天左右即可恢复生长；“光杆棉”类型恢复生长最慢，需一个月左右才开始现蕾，基本上无霜前花。产量以“有头类型”最高，其次为“无头有叶型”，“光杆型”产量最低，产量差异经方差分析达极显著水平。本研究对不同田头方式也进行了生育调查和产量测定，结果以“有残叶留双头”产量最高，其次为“光杆留双头”，“光杆留单头”最低．通过对不同受害类型雹灾棉产量调查，认为：（１）全部光杆，表皮砸烂的受害棉田应尽早进行翻种；（３）断头率在７０％～９０％，有部分残叶，大多数有生长点的棉田，尽量不要翻种，通过精细管理，籽棉产量可达１５００～２２５０ｋｇ／ｈｍ２，（３）断头率在４０％～７０％，叶片残留较多的棉田，通过管理，能迅速恢复生长，可获得３０００ｋｇ／ｈｍ２以上籽棉产量，一般不宜翻种。
In this paper, according to the different degree of victims of hail disaster cotton, several victim types were selected and the fertility status of cotton was investigated. The results showed that the growth was fastest with the “head and leaves” type, and the growth was recovered after about 10 days after the disaster. Light pole cotton “type recovery growth slowest, it takes about a month to start the bud, basically no frost before the flower. The yield was highest with ”head type“, followed by ”headless leaf type“, ”light rod type“ with the lowest yield, and yield difference by ANOVA reached extremely significant level. In this study, fertility surveys and yield tests were also conducted on different fields. The results showed that ”double leaves with residual leaves“ had the highest yield, followed by ”double leaves with light leaves“ and ”lowest light leaves with single leaves". According to the survey of hail-crop yield in different types of victims, it is considered that: (1) The damaged cotton seedlings with all bare rods and epidermal cells should be transplanted as soon as possible; (3) The rate of decapitation is between 70% and 90% The growth point of the cotton fields, try not to seed, through fine management, seed cotton production up to 1500 ~ 2250kg / hm2, (3) breakage rate of 40% to 70% leaves more cotton fields, through management, can quickly Restore the growth, can be more than 3000kg / hm2 seed cotton production, generally should not turn over.
