超宽膜棉花精量播种技术及经济效益分析

Analysis of super-wide film cotton precision sowing technology and economic benefits

针对北疆地区春季棉花播种后易发生降温、降雨、大风等倒春寒天气,影响棉花出苗和成长,导致棉花减产,给农户造成经济损失等问题,分析了4.4 m超宽膜棉花精量播种机械化技术,该技术较2.05 m常规膜种植技术增加采光面积22.3%,能有效提高地温,加快棉花生育进程,具有使棉花出苗快、出苗齐、现蕾时间早、结铃率高等优点。超宽膜棉花种植技术的推广与应用对实现棉花增产增收和提质增效具有重大的意义,其社会效益和生态效益显著。

After sowing cotton in spring of northern Xinjiang region,it is prone to cold weather such as temperature drop,rainfall and gusty winds,which affects the emergence and growth of cotton,leads to a reduction in cotton production and causes economic losses to farmers.Aiming at these problems,the mechanized 4.4m super-wide film cotton precision sowing technology was analyzed in this paper,compared to 2.05 m conventional film planting technology,this technology can increase the lighting area by 22.3%,this technology can increases the ground temperature effectively,promote the growth of cotton,promote the seedling and growth of cotton boll.The popularization and application of super-wide film cotton precision sowing technology has a significant meaning for increasing production,income,quality and efficiency of cotton,it also has significant social and ecological benefits.
