摘要
研究结果表明 ,在南疆兵团植棉农场 ,现行棉花施肥水平已能满足超高产 (皮棉 30 0 0kg·hm-2 )对大量元素的需求 ,限制产量提高的因子已不再是施肥量 ,应从微量元素施用、改善施肥方法及提高精细栽培水平方面入手。一般肥力水平的条田有实现超高产的可能 ,但若要持续高产、稳产 ,须培肥地力以增加或保持土壤较高的基础肥力。
It was a primary idea that the currently fertilized level needs demand for dominating elements of super high yield cotton in the farms of South Xinjiang. The quantities of fertilization were not a limitative element to increase yield. To further increase yield, it is more important to use fertilized microelement and improve fertilizing ways and culture measures. Fields with average fertility can gain super high yield. To continual keep high yield and steady yield, foster fertility, increase or retain higher fertility are necessey.
