Embodiment Construction

[0013] A method for raising seedlings by cuttings of black locust, the method comprising the steps of:

[0014] 1) Prepare the nursery ground, mix organic fertilizer, phosphate fertilizer, and potassium fertilizer evenly at a weight ratio of 40:1:1, apply the whole layer of the soil, and then cultivate the land at a depth of 30-35 cm. After plowing the land, harrow the ground ;

[0015] 2) Collect cuttings, collect 1-2 year old branches from the female parent of Robinia pseudoacacia, and cut them into spikes; the spikes are the middle and lower parts of the collected branches, the length is 15-20cm, the thickness is not less than 0.5cm, and there are 2-4 pieces Buds, the upper incision is 0.5cm away from the first bud, and the lower incision is 1cm away from the bottom bud; the seedlings need to be stored at a temperature of -5°C to 5°C;

[0016] 3) Pre-treatment of cuttings, use pentachloronitrobenzene mixture to sterilize the nursery ground, use ABT rooting powder to soak t...

Abstract

The invention aims to provide a seedling raising by cutting method for robinia pseudoacacia. The method comprises five steps of 1, preparing a seedling raising field, 2, collecting cutting branches, 3, preprocessing of the cutting branches, 4 cutting, and 5, cutting postprocessing. The seedling raising by cutting method is simple in step and low in cost, can effectively improve the survival rate of the robinia pseudoacacia, has no harsh demands on seedling raising environment and greatly reduces the seedling raising cost, and the seedling raising survival rate per mu is as high as 95%.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a method for cultivating black locust seedlings by cuttings. Background technique [0002] Black locust is an important tree species for afforestation, especially in the northern region, black locust accounts for a large proportion of forest tree species. The root of black locust is very strong, which is of great significance to the development of natural forestry and the expansion of forest resources. However, the rate of black locust seedlings now It is not high, which greatly restricts the popularization and planting of black locust, and has caused great difficulties to the afforestation in the northern region. Contents of the invention [0003] The purpose of the present invention is to provide a method for cultivating black locust seedlings by cuttings, which solves the problem of low survival rate in the existing methods for cultivating black locust seedli...
