Large-leave fast-growing locust tree nutrition plate seedling method

Abstract

The invention relates to a large-leave fast-growing locust tree nutrition plate seedling method. The method comprises the following steps of: (1) selecting a proper seedling period; (2) preparation work before seedling: preparing a plastic shed, preparing corresponding porous nutrition plates according to different mother root diameters, cutting the mother roots of fast-growing locust trees into root sections of certain lengths, cutting the mother roots with the diameters of over 5 mm into the root sections of 8 cm, cutting the mother roots with the diameters of 3 to 5 mm into the root sections of 10 cm, screening soil, drying the soil, and removing impurities from the soil; (3) cutting the mother roots: filling the soil, cutting the mother roots, spraying water, putting the mother roots on a frame, and keeping the temperature of the shed; (4) seedling management: keeping the humidity and weeding periodically; (5) transplanting: selecting a proper time, preparing a land, digging holes, spraying the water, transplanting, and spraying the water again; and (6) management after transplanting: keeping the humidity, weeding and performing the deinsectization. By the seedling method provided by the invention, the propagation coefficient of the mother roots can be improved; the seedling time can be shortened; the survival rate of the mother roots can be improved; the using amount of nitration soil is reduced; and the concentrated seedling unified management is facilitated.

Description

technical field [0001] The invention relates to the technical field of artificial seedling breeding and reproduction, in particular to a method for growing seedlings of fast-growing large-leaf locust locust trees in a nutrient tray. Background technique [0002] Big-leaf fast-growing locust tree is a deciduous tree of the leguminous Robinia genus, and it is a new type of feed tree species. The leaves of the big-leaf fast-growing locust tree are broad and large, the length and width of the leaves are 2-3 times that of common Robinia pseudoacacia, the leaf quality is thick, and the dry weight of a single leaf is 4-6 times that of common Robinia pseudoacacia. The leaves are odd-pinnate compound leaves, alternate and entire. The leaflets are 7-19 pieces, elliptic or oval, smooth and glabrous on both sides. The big-leaf fast-growing Sophora japonica is a unisexual flower, purple-red, in racemes, without stamens, and does not set seeds. It mainly uses seed roots for reproduction...

Problems solved by technology

[0007] In the process of rooting and breeding of fast-growing locust locust seedlings, some problems are often encountered. The first is how to use the thinner roots (3-5mm) of the lateral roots of the fast-growing locust locust tree. Second, in the north, during the Spring Festival The soil thaws relatively late, so how to increase the number of harvests of fast-growing Sophora japonica branches and leaves during the annual growth period
