Problems solved by technology

[0003] The traditional propagation method of neem tree is to use neem seeds for sowing and propagation. Although the operation technology requirements are not high and the seedling rate is relatively ideal, it cannot completely retain the excellent traits of the female parent and cannot be used for the breeding of improved seedlings.

Embodiment 1

[0029] The invention provides a method for raising seedlings by cuttings of neem fine root segments, comprising the following steps:

[0030] Prepare the cuttings: choose a strong neem tree that grows vigorously and is free from diseases and insect pests, dig out the root system with a thickness of 0.3~0.5cm about half a month after the leaves fall in winter, and quickly bring them back indoors, and cut off the fine roots at the end of these thin heels , cut into 8-10cm long sections, the upper incision is flat and round, the lower incision is horseshoe-shaped, and the incision is smooth, after that, 20 pieces are bundled into a bundle, and sand storage is carried out for 60 days by the open field mixed river sand lamination irrigation method;

[0031] Cutting pretreatment: Soak the fine root section cuttings after sand storage with 600ppm carbendazim and 600ppm naphthaleneacetic acid aqueous solution for 20h;

[0032] Cutting: choose to cut after 3 p.m. in mid-March. When cut...

Abstract

The invention relates to a method for cutting seedling raising of a fine root section of chinaberry. The method comprises the following steps of preparing cuttings; pre-treating the cuttings after sand storage; cutting; managing after the cutting. The method for cutting seedling raising of the fine root section of the chinaberry is simple and reasonable in cultivation steps, is easy to grasp, caneffectively improve the excellent clonal reproductive coefficient of the chinaberry, and is fast in seedling raising speed and low in the cost. In addition, nutrition cup seedlings are convenient to transplant, and the survival rate of the seedling raising is as high as 96%, which can effectively promote the development of the chinaberry industry.

Description

technical field [0001] The invention relates to the technical field of forest tree seedling cultivation, in particular to a method for cultivating neem tree seedlings by cutting fine root segments. Background technique [0002] Neem is an excellent native tree species in my country. It grows fast, has excellent materials, beautiful tree shape, beautiful branches and leaves, and elegant and fragrant flowers. It is an excellent tree species for fast-growing materials and landscaping; It is one of the broad-spectrum botanical pesticides with high efficiency and low toxicity; Neem is also a good nectar source plant, and its fruit is an industrial raw material for oil extraction and wine making; With vigorous development, the demand for strong seedlings of Neem tree is also increasing. [0003] The traditional propagation method of neem tree is to use neem seeds for sowing and propagation. Although the operation technology requirements are not high and the seedling rate is relativ...
