Abstract

The invention discloses a root cutting afforestation method of melia azedarach in a saline and alkaline land. The method comprises the following steps: (1) selection and preparation of land; (2) seminal root selection; (3) seminal root processing; (4) root cutting afforestation; (5) managing after the root cutting. The root cutting afforestation method provided by the invention is simple to operate and low in cost, and the survival rate of root cutting afforestation can reach up to above 90%, therefore the large area popularization of the melia azedarach can be beneficially realized.

Description

technical field [0001] The invention relates to a method for afforestation in saline-alkali land, in particular to a method for afforestation in saline-alkali land by cutting neem root. Background technique [0002] Neem is widely distributed in my country. It is a fast-growing, multifunctional and comprehensively utilizable tree species, and has broad development and utilization prospects. At present, the method of using neem afforestation is mainly for seedling afforestation, and seedling cultivation includes sowing seedlings, rooting seedlings, grafting seedlings, transplanting seedlings, etc., and then afforestation. The above-mentioned afforestation method has low survival rate, high cost and poor cultivation effect in saline-alkali land, and the final afforestation cycle is long, the survival rate is low, and it is not suitable for large-scale promotion. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the pres...
