Example Embodiment

[0018] Example 1

[0019] (1) Choose a specification of 150g / m 2 Black non-woven fabric made of polypropylene PP is a grass-proof material;

[0020] (2) According to the diameter of the seedling container, cut the material of step (1) into a disc with a diameter of about 1cm smaller than the diameter of the seedling container, dig a hole in the center of the disc with a diameter of about 2cm, and then move the center hole to the edge of the disc. Cut at the radius for easy placement;

[0021] (3) Soak the disc prepared in step (2) in a solution of 23.5% oxyfluorfen (Gore) EC 15ml + 10.8% high-efficiency fluroxypyr (Gychoenen) 10ml plus 10L of water for 2h ,spare;

[0022] (4) Covering the disc of step (3) on the surface of the container after sowing and covering the thin-shell pecan, the seedling of the thin-shell pecan is about 30-40 days, there is no weed in the container, and the weed control efficiency reaches 98%.

Example Embodiment

[0023] Example 2

[0024] (1) Choose a specification of 120g / m 2 Black non-woven fabric made of polypropylene PP is a grass-proof material;

[0025] (2) According to the diameter of the seedling container, cut the material of step (1) into a disc with a diameter of about 1 cm smaller than the diameter of the seedling container, dig a hole in the center of the disc, the diameter of which is slightly larger than the seedling ground diameter, and then move the center hole to the disc Cut a radius at the edge for easy placement;

[0026] (3) Soak the disc prepared in step (2) in 5ml of 23.5% oxyfluorfen (Gore) EC 5ml + 10.8% high-efficiency fluroxypyr (Gychoenen) 5ml plus 10L of water for 1h, spare;

[0027] (4) Covering the disc of step (3) on the surface of the container of the seedlings with the germination soil for more than 60 days, the weed control efficiency is 98%.

Example Embodiment

[0028] Example 3

[0029] (1) Choose a specification of 150g / m 2 Black non-woven fabric made of polypropylene PP is a grass-proof material;

[0030] (2) According to the diameter of the seedling container, cut the material of step (1) into a disc with a diameter of about 1 cm smaller than the diameter of the seedling container, dig a hole in the center of the disc, the diameter of which is slightly larger than the seedling ground diameter, and then move the center hole to the disc Cut a radius at the edge for easy placement;

[0031] (3) Soak the disc prepared in step (2) in 10ml of 23.5% oxyfluorfen (Gore) EC 10ml + 10.8% high-efficiency fluroxypyr (Gychoenen) 5ml plus 10L of water for 2h, spare;

[0032] (4) Covering the disc of step (3) on the surface of the container for holding bed seedlings, the weed control efficiency is 95%.

Abstract

The invention discloses a method for preventing and controlling weeds of container nursery and belongs to the technical field of forest cultivation. The method comprises the following steps: (1) preparing a weed-preventing material; (2) preparing; (3) soaking; and (4) covering. The rate for preventing and controlling weeds of container nursery reaches up to 95% or above according to the method.

Description

technical field [0001] The invention relates to a method for cultivating woody plants, in particular to a method for controlling weeds in container seedling cultivation. Background technique [0002] Container seedling cultivation is a seedling production technology widely used in various countries in the world today. It uses various containers to fill the prepared nutrient soil for seedling cultivation. It has the advantages of not being restricted by seasons, high survival rate of afforestation, short seedling period after afforestation, and fast growth. , especially suitable for cultivating tree species with low transplant survival rate, and container seedlings can be widely used in afforestation in areas with poor site conditions such as drought and barren. [0003] Weed damage is the main problem faced in the cultivation of seedlings. Weeds not only compete with seedlings for water, nutrients and light, but are also the source of breeding diseases and insect pests, hind...
