我区常年植棉70万亩左右.回顾1968年以来的棉花生产情况,大体经历了三个时期.1968~1970年棉花采用直播,套种在以大元麦为主、麦幅占地35%左右的麦垅中,茬口好,亩产119.6斤.1971~1977年棉花前茬片麦面积大(50~60%),条播麦幅占地40~50%,腾茬季节迟,棉花产量下降,亩产为91.9斤.1978年以来棉花以育苗移栽为主,产量有所上升,亩产为102.4斤.为使棉花产量能持续增长,更好地发挥移栽棉增产优势,我们从棉花生产有关资料,分析了增产潜力.
The cotton planting area in our district is about 700,000 mu all the year round.Reviewing the cotton production situation since 1968, it has generally experienced three periods: 1968 ~ 1970, the cotton was broadcast live, Of the wheat stubble, stubble is good, 119.6 kg per mu .1971 ~ 1977 cotton stubble wheat area (50 ~ 60%), strip sowing an area of 40 to 50%, late season stubble, cotton production decreased, The yield per mu is 91.9 kg. Since 1978, the main transplanting of cotton to seedling has given rise to an increase of 102.4 kg per mu. In order to make the cotton yield continue to grow and give full play to the superiority of cotton transplanting cotton, Relevant information, analysis of the potential yield.
