关于棉花种植密度,有的主张靠发挥单株增产潜力搞稀植大棵,有的注重发挥群体增产潜力搞小棵密植,还有主张既靠单株又靠群体.就实践而言,都有成功的高产实例.分析其原因,认为影响棉花密度的诸因素,可以分为基本稳定因素和不稳定因素两大类,基本稳定因素包括当地热量条件、播期、品种熟性等,这些因素实质上是一个棉花生育期对热量利用多少的问题;不稳定因素包括土壤肥力、水肥条件、管理水平等.
On the cotton planting density, and some advocates to play a single plant yield potential engage in thin planting big trees, and some pay attention to the potential to increase production of small groups engage in small densely populated, there are claims by both groups and by groups .In practice, there are Successful examples of high yield.Analysis of the reasons that the factors that affect the cotton density can be divided into two major categories of basic stability and instability factors, the basic stability factors include local calorific conditions, sowing date, varieties of maturity, the essence of these factors On the cotton growth period is the use of calories on the number of issues; instability factors include soil fertility, water and fertilizer conditions, management and so on.
