甘蔗种植深耕深松技术应用效果试验

Effects of applying deep plowing and scarification techniques in planting sugarcane

甘蔗种植深耕深松技术是甘蔗优质高产、抗旱抗寒、抗倒伏、保水保肥栽培的重要措施之一。2005年对蔗地进行拖拉机深耕深松与牛耕对比试验，结果表明：使用48KW中型拖拉机悬挂深耕犁、深松机进行深耕深松作业，甘蔗出苗率比牛耕提高19．3％，分蘖率提高28．9％，根数增多3．8条／株，根长增21．1cm，根重增19.8g，土壤含水量增加0．5％～1．5％，干旱时达1．7％；每公顷增产原料蔗18．15t，增值4719元。

It is one of important measures to get high yield and quality, resistance to drought, cold and lodging, proper water--conservation and fertilizer-maintenance by taking deep plowing and scarification in sugarcane cultivation. In 2005, deep plowing and scarification by tractor were conduced compared with plowing by cow. The resuits showed that the seedlings emergence rate was increased by 19. 3%, the tillering rate was increased by 28.9%, the roots per plant increased 3.8 and the root length increased by 21.1cm, and the root weight increased 19.8g. In addition, the water content in soil increased by 0. 5%-1. 5% under normal condition or 1.7% during the drought. The cane yield was increased by 18. 15t/hm^2 with 4719 RMB when the land was deeply plowed by 48 KW medium type tractor.
