通过试验及其结果的生产反馈验证,并经方差分析和多重比较,得出江西不同生态土壤类型对棉花八个性状影响的一般规律,即:湖积粘土棉地棉花生育期较长,后劲足;湖积土中壤区棉花株高较其它土壤类型矮;麻砂泥土中壤区棉花实行营养钵育苗移栽的单株成铃数和单铃重高于直播棉,而衣分、产量则与种植密度相关性很大。从而提出生产上应根据不同生态土壤类型采取相应的对策,以提高棉花的产量和品质。
Through the test and the result of the production feedback verification, and by analysis of variance and multiple comparisons, the general rules of different ecological soil types on the eight traits of cotton in Jiangxi Province were obtained: cotton lacustrine clay cotton has a long growing period and sufficient stamina . The cotton plant height in mid-loamy soil was shorter than that in other soils. The boll number and single boll weight per plant of transplanting cotton seedlings in medium-sand soil were higher than that of direct-seeded cotton, Relevant to the planting density is very large. It is suggested that the production should be based on different types of ecological soil to take appropriate measures to improve cotton yield and quality.
