一、棉田耕整地机械化技术棉田耕整地机械化技术的核心是深耕、深松,熟土层要深翻,心土层要深松,耕作层深度应大于22厘米。土层深厚肥沃,质地疏松,才能使棉花吸足养料和水分,生长发育好,以利于高产和提高纤维品质。棉田耕整地机械化技术主要有三种形式:1.深耕机械化技术。该技术用铧式犁或圆盘犁实现翻土、松土和混土,以利于恢复土壤团粒结构,增强蓄水保 I. Cotton Field Tillage Mechanization Technology The core of cotton field tillage mechanization is deep plowing and deep plowing. The deep plowing should be deep plowing and the soil layer should be deep plowing. The depth of plowing layer should be greater than 22 cm. Thick and fertile soil, loose texture, in order to make cotton absorb enough water and nutrients, good growth and development, in order to facilitate high-yield and improve fiber quality. There are three main forms of cotton field mechanization technology: 1. Deep plowing mechanization technology. The technology with a plow or disc plow to achieve soil, loose soil and mixed soil, in order to facilitate the restoration of soil aggregate structure, enhanced water storage
