Embodiment 1

[0019] (1) The selected specification is 150g / m 2 The 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 in step (1) into a disc with a diameter about 1 cm smaller than the diameter of the seedling container, dig a hole in the center of the disc with a diameter of about 2 cm, and then cut the hole from the center to the edge of the disc. Cut off the radius for easy placement;

[0021] (3) Soak the disc prepared in step (2) in a solution of 15ml of 23.5% oxyfluorfen (guoer) EC + 10.8% of high-efficiency haloxyfop (Gaicao Neng) 10ml and 10L of water for 2 hours ,spare;

[0022] (4) Cover the disc of step (3) on the surface of the container after the hickory is sown and covered with soil. The hickory will emerge in about 30d to 40d, and there will be no weeds in the container, and the weed control efficiency will reach 98%.

Embodiment 2

[0024] (1) The selected specification is 120g / m 2 The 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 in step (1) into a disc with a diameter about 1cm smaller than the diameter of the seedling container, dig a hole in the center of the disc, the hole diameter is slightly larger than the diameter of the seedling, and then connect the center hole to the disc Cut a radius on the edge for easy placement;

[0026] (3) Soak the disc prepared in step (2) in 5ml of 23.5% oxyfluorfen (guoer) EC + 10.8% high-efficiency haloxyfop (Gaicao Neng) 5ml and 10L of water for 1 hour, spare;

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

Embodiment 3

[0029] (1) The selected specification is 150g / m 2 The 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 in step (1) into a disc with a diameter about 1cm smaller than the diameter of the seedling container, dig a hole in the center of the disc, the hole diameter is slightly larger than the diameter of the seedling, and then connect the center hole to the disc Cut a radius on the edge for easy placement;

[0031] (3) Soak the disc prepared in step (2) in 10ml of 23.5% oxyfluorfen (guoer) EC + 10.8% high-efficiency haloxyfop (Gaichoneng) 5ml and 10L of water for 2 hours, spare;

[0032] (4) The disk of step (3) is covered on the surface of the container of the bed seedlings, and 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...
