1991~1993年通过试验和调查研究表明,移栽棉采用“一壮、二促、三控”全程化调技术,有利于促根壮苗,早发稳长,定向诱导各器官的生长发育,塑造高光效株型,改善蕾铃的营养条件,对促进早熟高产优质具有明显作用。棉花每公顷增产112.5~157.5kg,较对照增产15.08%~21.45%;结铃期喷施叶面肥可增产6.12%~8.98%。同时,初步研究了棉花全程化调的形态指标,为生产上合理化调提供了科学依据。
From 1991 to 1993, experiments and investigations showed that transplanting cotton used “one strong, two boosts and three controls” to regulate the whole process, which was good for root growth and seedling growth, early onset and steady growth, and directional growth and development of various organs. Shaping light-efficient plant type, improve the nutritional conditions of the buds, to promote high yield of early maturity has a significant role. The yield of cotton increased 112.5 ~ 157.5kg per hectare, 15.08% ~ 21.45% higher than that of CK. The foliar application of boll irrigation could increase the yield by 6.12% ~ 8.98%. At the same time, the preliminary research on the morphological index of cotton whole process has provided a scientific basis for rational adjustment of production.
