摘要
为了实现关中短季棉高产栽培 ,在夏棉春育 ,麦垅移栽 ,农膜全程覆盖的基础上 ,采取多因素综合试验 ,研究了麦垅移栽棉的不同密度与复硝钠、化肥施用量次与产量的函数关系。在前茬收获 662 5 .6kg/ hm2小麦的情况下 ,获得皮棉产量≥ 1 5 0 0 kg/ hm2农艺措施最佳组合 ,并进行了反馈试验和大田示范。经对不同植棉方式的经济效益和纤维品质比较 ,证明本研究是关中两熟高产的有效途径。
To realize high yield cultivation of short stage cotton in Guanzhong,the comprehensive test of multi factors was conducted on the basis of seeding nursing in spring,trans plant and membane cover during all stages for summer cotton.Regressive relationship between yield and densty,Fuxiaona and fertilization was studied and optional combinations of agronomic measures for 1 500 kg/hm 2 of limit yield were screened with 6 625.6 kg/hm 2 of wheat,the confirming tests and demonstrations were carried out.From the comparison of economic benefit and fiver quality of various plant pattens in cotton,the result was an effective way to high yield of two maturity cultivation in Guanzhong
