我县近年来利用水田植棉的面积达到二万多亩,由于能针对水田土壤的特点,采取相应的栽培技术,使棉花单产不低于老棉地,有的头年种棉亩产就超过了百斤,最高的试验田,头年的单产达到220多斤。现就稻棉轮作中水田植棉的特点和植棉技术试作一全面的总结分析,以供参考。一、水改旱植棉的特点水改旱种棉花,由于土壤粘性重,板结渍通水,透性差,土温较低,土壤潜在养分高而分解释放较慢,因而对
In recent years, our county has used more than 20,000 mu of cotton paddy field area. Due to the characteristics of paddy soil, we can adopt appropriate cultivation techniques to make cotton yield not less than that of old cotton paddy field. A hundred jins, the highest experimental field, the first year of yields reached 220 kilos. Now rice paddy for paddy field in the characteristics of cotton and cotton technology trial for a comprehensive summary of the analysis for reference. First, the characteristics of water to change cotton plant drought cotton, due to heavy soil viscosity, plate junction water, poor permeability, low soil temperature, high potential soil nutrients and decomposition of slow release, and therefore right
