利用吐鲁番无霜期长,积温高的有利自然条件,充分发挥棉花株型的可塑性等生长特点,通过矮密早栽培技术,对棉花利用温度空间进行重新分配,可以实现棉花复播绿肥的耕作方式。当年棉花单产比传统稀植栽培提高10—15%,绿肥鲜草产量达到2.2—2.5吨。新的耕作方式对连作棉田、低产棉田可起到显著的土壤培肥和增产作用。
By utilizing the favorable natural conditions of Turpan frost-free period and high accumulating temperature, cotton plant type plasticity and other growth characteristics can be fully utilized. Through short and close planting techniques, redistribution of cotton using temperature space can realize the tillage mode of cotton compound green manures. In that year, the cotton yield was increased by 10-15% compared with that of the traditional sparse planting and the yield of fresh green manure reached 2.2-2.5 tons. The new farming methods can be used as continuous cotton fields, low-yield cotton fields can play a significant soil fertility and increase production.
