摘要
适宜的田间栽培模式有利于提高农田水分利用率和作物产量,以田间试验为基础,地下滴灌条件下将无膜移栽(NFTSDI)、覆膜移栽(WFT-SDI)和覆膜直播(FS-SDI)三种栽培方式棉花的生长和产量进行对比分析。结果表明:与WFT-SDI、FS-SDI处理相比,NFT-SDI棉花生育期仅比WFT-SDI多2 d,脱蕾铃率低,叶面积指数适宜,根系最长,为136 cm,有利于中部侧根系发育,对棉花根长发育和根冠长比增大有积极作用。在耗水量相当的情况下,NFT-SDI比FS-SDI、WFT-SDI棉花籽棉产量分别增加了0.57%和7.86%。
Appropriate field cultivation mode is beneficial to improve water use efficiency and crop yield.Based on the field experiment and under the conditions of subsurface drip irrigation,the growth and yield of cotton were compared by the three cultivation methods of transplan tation without film(NFT-SDI),transplantation with film(WFT-SDI)and the seeding with film(FS-SDI).The outcomes show that compa ring with WFT-SDI and FS-SDI treatments,NFT-SDI cotton growth process is only 2 days behind WFT-SDI.The Shedding rate of bud and boll is low,the leaf area index is suitable,and the longest root system is 136 cm,which is conducive to the development of central lateral root system,has a positive effect on cotton root length development and increase of root shoot ratio.In the case of equivalent water consump tion,NFT-SDI is increased by 0.57%and 7.86%respectively in cotton seed cotton production compared with FS-SDI and WFT-SDI.
