摘要
为解决秋葵育苗中死苗的问题,以秋葵为试材,研究了在秋葵育苗过程中施用石灰对其幼苗生长发育的影响,结果表明,施用一定浓度的石灰能促进秋葵根系发育,提高根系活力、根系质量、根冠比、侧根数;能显著地增加秋葵幼苗的叶面积、植株高度和茎粗度。其中以采用4%的石灰均匀拌入土壤的方式效果较好,根系活力、根系质量、根冠比、侧根数分别较对照提高19.17%、62.86%、65.78%、67.27%、4.61%。
To solve the problem of okra seedlings of dead plants. This test with okra as experimental materials, study the okra in seedling of lime in the process of applying the seedling growth, the influence of the test results show that the use of a certain concentration of lime can promote okra root development, increase root activity, root weight, root cap ratio, lateral root number; Can significantly increase the okra seedlings leaf area, plant height and stem diameter. Of which 4% of uniform stir in lime soil effect is better.
