摘要
湖南棉花高产栽培技术体系形成于80年代末,90年代初臻于完善、配套,并以技术标准的形式在全省棉区推广应用.其技术体系的基本框架为:适时播种(4月10~25日)——育苗移栽,促壮苗早发(5月底6月初现蕾,8月20日左右吐絮)——宽行稀植(行距80~100cm,密度37500株/hm2),大棵壮株(单株成铃27个以上)——全程调控(肥促化调为主)——主攻秋桃(占总铃数的50%左右),单产1500~1875kg/hm2.
The technical system of high yield cotton culture in Hunan province was established at the end of 80s and perfected in the beginning of 90s. The technical standards of the system have been spreaded and prictised in the cotton growing area of the province,which sowing at poroper time (during April 10 ̄25th)to prevent the seeds from rotting or the seedlings from dying,cultivating the seedlings and transplanting to raising sturdy seedlings,thin transplanting (row space between 80 ̄100 cm,desity about 37 500 plants per hm 2),regulating the whose growing stages,increasing the ffruiting rate (about 50% of the all bolls) and yielding at 1 500 ̄1 875 kg per hm 2.
