【摘要】 2007年在澧阳平原棉区,进行棉花不同育苗方式育苗效应的比较研究,结果表明:水浮育苗技术较传统的营养钵育苗技术在出苗率、株高、茎粗、鲜重和移栽成活率方面有很大的提高;基质育苗移栽成活率低于营养钵育苗,但其他方面较好.营养钵育苗技术耗工多,生产风险大,累计成本较高,与之相比,基质育苗和水浮育苗省种、省工、有利于劳力转移.更多还原

【Abstract】 Result as follow: the raising-in-water seedlings contain much exaltation in the rate of seedlings emergence, height, the stem diameter, the fresh weight and transplant survival rate in comparison with the traditional nutrition earthen bowl seedling. The matrix seedlings’ transplant survival rate is lower than that of nutrition earthen bowl seedlings, while other aspects are better. The traditional nutrition earthen bowl seedlings technique consume much more seeds and labor than seedlings without soil, and the production involves a higher degree of risk, the accumulation cost is higher too. By comparing with it, the matrix seedlings and the raising-in-water seedling are much more labor-saving, so it is advantageous to the labor force shifting, and heighten the net output value.更多还原
