Method for transplanting sprout stocks of zelkova serrata

Abstract

The invention discloses a method for transplanting sprout stocks of zelkova serrata, belonging to the field of plantlet culturing. The method comprises the steps of (1) deeply ploughing soil in winter, applying a thoroughly decomposed organic fertilizer, preparing the soil to realize the purposes that a seedbed is 1.0-1.2m in width and 30-40m in height, and disinsecting and weeding the seedbed; (2) during the last ten-day period of the April and the first ten-day period of the May, transplanting the sprout stocks when the sprout stocks of the zelkova serrata grow to be with two leaves and one core respectively, or grow to be with 6-10 leaves, and the roots of the sprouts are 3-5cm in length, lifting the sprout stocks and the transplanting; (3) erecting a sunshade net on the seedbed after the transplanting, and managing after the transplanting. According to the method, the sprout stocks are transplanted according to the characteristics of the seedling period of the zelkova serrata, the defects of low emergence rate of the sowing seedlings and irregular emergent seedlings can be compensated by adjusting the breeding state of the plantlets, the strong seedlings of the zelkova serrata are cultured, and the demands of the society on the zelkova serrata can be met.

Description

technical field [0001] The invention relates to the field of nursery stock cultivation, in particular to a method for transplanting beech sprouts. Background technique [0002] Beech is an arbor tree species of the genus Beech in the family Ulmaceae, and it is a national second-class key protected plant. It is widely distributed in our country and grows fast. It is a precious hard broad-leaved tree species. Now beech trees are often used for road greening, because beech trees are resistant to smoke and dust, anti-pollution, and have a long lifespan, so they are favored by people. [0003] However, the growth of zelkova is relatively slow at the seedling stage, and it gradually accelerates after 6 to 7 years. The cultivation at the seedling stage is very critical. The density of the seedlings cannot be controlled by the traditional live seeding in the field, which will lead to uniform growth quality of beech trees, poor tree shape, strong tap roots of seedlings, underdevelo...

Problems solved by technology

[0003] However, the growth of beech trees in the seedling stage is relatively slow, and it will gradually speed up after 6 to 7 years. The cultivation in the seedling stage is very critical.

The density of the seedlings cannot be controlled by the traditional live seedlings in the field, which will lead to uniform growth quality of beech trees, poor tree shape, strong tap roots of seedlings, underdeveloped fibrous roots, and affected survival rate.
