Use of Eupatorium adenophorum in high-yield walnut cultivation

Abstract

The invention relates to the use of Eupatorium adenophorum in high-yield walnut cultivation. In the invention, Eupatorium adenophorum plants are harvested from the flowering period in September to the mature period of the Eupatorium adenophorum each year and are transported to the lands covered by walnut trees in time; the Eupatorium adenophorum plants are used to cover the ranges of the crown projections at the root parts of the walnut trees and are compacted in a thickness of 6 to 8 centimeters; after the root parts of the walnut trees are covered by the Eupatorium adenophorum plants for one year, namely the covering materials are half rotted, the Eupatorium adenophorum together with autumn base fertilizer serves as an organic fertilizer source to be turned into soil; Eupatorium adenophorum plants are harvested and used for covering again; and by repeating like this, the Eupatorium adenophorum spreading hazard is avoided, and on the lands on which the walnut trees are planted, water is retained, soil is modified and organic fertilizer sources are increased. The invention has a good Eupatorium adenophorum spreading prevention effect, can promote the fruiting of walnut trees and increase the walnut yield, contributes to the prevention, control and use of forest harmful organisms and has a wide use prospect in production.

Description

technical field

[0001] The invention relates to the fields of agricultural prevention and control of forest weed damage and economic forest cultivation, in particular to the application of Eupatorium adenophorum in high-yield cultivation of walnuts. Background technique

[0002] Eupatorium adenophorum belongs to the Asteraceae family, Eupatorium genus, is a perennial herb, native to Mexico in the Americas, invaded my country around 1950, and has now spread to Yunnan, Guizhou, Sichuan, Guangxi and other provinces and regions, with an annual growth rate of about 30km The speed continues to advance northward. Now it has become one of the main forest grass damages in Yunnan Province. Eupatorium adenophorum mainly relies on its densely integrated biological characteristics and amazing reproductive ability to repel the growth of other plants. Where Eupatorium adenophorum grows, other herbaceous plants basically cannot grow and absorb a large amount of nutrients in the soil, thus s...

Examples

Embodiment Construction

[0010] Every September, before Eupatorium adenophorum blooms and the seeds are immature, the plants of Eupatorium adenophorum are collected by manual pulling or cutting. At this time, because the seeds of Eupatorium adenophorum are not mature, it can effectively prevent its spread At the same time, at this time, the soil moisture content is high and it is the period of basal fertilizer application in autumn. It can be combined with mulching after basal fertilizer application. After covering, it is beneficial to maintain the soil moisture content for a long time.

[0011] Collect Eupatorium adenophorum plants and wrap them into bundles, each bundle weighing about 20kg, and transport them to the walnut tree covering plot in time; use Eupatorium adenophorum plants as mulch in time, and evenly cover the projection range of the crown at the base of the walnut tree; when covering Eupatorium adenophorum is compacted to a thickness of 6-8cm, and the coverage area is not less than 4m 2...
