摘要
通过多点试验,筛选出适于我市春育夏栽的棉花品种中12,明确了4月5～15日为最佳育苗播种期,5月30日～6月5日为移栽适期,最适苗龄40～50天。对大苗移栽棉花使用缩节胺进行化控时,应根据天气旱涝、棉株长势,酌情确定喷施量和喷施时期,以免影响棉株正常生长,导致减产。
Through repeated spot experiment, the cotton cultivar Zhong No 12 suited for Xinxiang was selected which can be breeded in Spring and planted in Summer . The optimum breeding data were obtained from 5 to 15 in April and the optimum transplanting time was from May 30 to June 5. The best seedling age was 40-50 days. According to the climate and growth state of cotton, spraying amount of Pix and spraying data were modified if chemical control can be used for the transplantign cotton seedling growth.
