移栽地膜棉的增产机理是“增温、增光、保肥、调墒”,重点是利用好增温、增光的有利条件,延长有效开花结铃期。其生长发育特点是“生育早、发棵快、果节多、有效开花结铃期长、容易早衰”,通过几年的试验示范,移栽地膜棉可增产1~2成,是继80年代直播改移栽以来的又一次重大的栽培技术改革,显示了大幅度增产的潜力。本文总结了移栽地膜棉的生态生物学效应及相应的栽培配套技术。
Transplanting cotton membrane cotton yield-increasing mechanism is “warming, adding light, fertilizer, adjust soil moisture,” the focus is to make good use of temperature, light conditions, to extend the effective flowering period. The characteristics of its growth and development are “early growth and fruiting fast, fruiting section, effective flowering period long, easy premature aging,” After several years of experimental demonstration, cotton transplanting cotton yield 1-2 can be increased, following the 1980s Another major cultivation technology change since the live broadcast of the transplanting shows the potential for a substantial increase in output. This paper summarizes the ecological and biological effects of transplanting cotton membrane and corresponding cultivation techniques.
