我省是两熟棉区,棉花播种出苗阶段有前作荫蔽,棉田光、热、气、肥、水等条件均差,而且苗期田间管理也有一定的困难,容易造成缺苗或棉苗迟发。我省过去小麦茬与蚕豆茬棉花现蕾期一般比春花迟半月以上,产量仅为春花的70％。近年来推广棉田的早管经验后,两熟棉田的现蕾期比以前有所提早,产量也大大提高了。经验证明,棉花早发、早熟,显著比迟发、晚熟的增产。为了进一步提高棉花产量,必须在一播全苗的基础上,全面推广一播就管和壮苗早发的措施。

Our province is a double ripe cotton area, the seedling stage of cotton sowing is covered with shade before. The conditions of light, heat, gas, fertilizer and water in cotton field are poor. Moreover, field management in seedling stage also has some difficulties, which may lead to delayed emergence of seedling or cotton seedling . In the past, the stalks of wheat and stubble in our province were generally more than a half months later than that of spring, and the yield was only 70% of that of spring flowers. In recent years to promote the experience of cotton fields in early management, the budding period of two cotton fields earlier than earlier, the output has also greatly increased. Experience has shown that cotton is early-onset, early maturity, significantly more than delayed, late maturity of the yield. In order to further increase the cotton yield, we must comprehensively promote the dissemination of tobacco and seedlings on the basis of a broad-based seedlings and early measures for seedling growth.
