研究腐殖酸颗粒肥在盐碱地棉花上的应用效果,结果表明:棉田施用腐殖酸可以降低棉田的次生盐渍化危害,对棉花生育期的影响较小,各生育期基本与常规栽培保持一致,伏前桃、伏桃成铃率接近,秋桃较常规栽培增加较多,达0.5个桃。同时,可增强棉株生长势,调节棉株早衰,纯收益增加1 634.94元/hm2,可在瘠薄地块及连作棉田作基肥深施推广使用。
The results showed that the application of humic acid in cotton field could reduce the secondary salinization damage in cotton field and had little effect on the growth period of cotton. The growth stages were basically the same as the conventional cultivation Consistent, Voltata peach, Fantasia boll rate close, autumn peach increased more than conventional cultivation, up to 0.5 peaches. At the same time, cotton plants can enhance the growth potential, premature aging cotton plant regulation, net income increased by 1 634.94 yuan / hm2, can be used in barren land and even cotton fields as a base fertilizer to promote the use of.
