Problems solved by technology

The Chinese patent application number 201010130907.1 discloses a method for mulching citrus orchard soil with straw. In this method, there is too little coverage with straw in the orchard, and it is impossible to control the weeds in the furrows of the fruit trees from spreading to the covered area. In addition, some fruit trees such as The plant height of blueberry trees is far less than that of citrus. Too thick coverage will affect the growth and yield of blueberries, and cannot meet the coverage thickness required by the patented technology, which will affect the weed suppression effect.
The Chinese patent with the application number 201310476335.6 discloses a method of ecological weeding. This method cannot remove all weed seeds, nor ca

Embodiment 1

[0026] A method for suppressing the growth of weeds in the newly planted field of blueberries of the present invention, the specific method is as follows:

[0027] Dig loose cultivated land first, add soil pH regulator (sulfur powder), clean up the weeds on the ground, and draw out the border surface 1 according to the requirements, and draw out the location of the cultivation hole according to the required row spacing (in order to cover the tarpaulin conveniently, it is required to The position of the row cultivation hole is in a straight line, and a 40*40*40 cm or 50*50*50 cm square blueberry cultivation hole is excavated), and then the cultivation hole is filled with nutrient soil (commercially available general-purpose nutrient soil), and the surface of the nutrient soil should be Lower than the surface, cultivate the blueberry seedlings 7 in the cultivation holes again, after the blueberry seedlings 7 have been cultivated, pour water for pressing, and then cover the cultiv...

Embodiment 2

[0031] A method for suppressing the growth of weeds in old blueberry plantation grounds of the present invention, the specific method is as follows:

[0032] Clear the weeds in the blueberry tree cultivation garden so that there are no weeds growing around each blueberry tree; hoe the blueberry cultivation land and kill the weeds. Remove the surface soil around the blueberry tree to a layer of soil with a thickness of 2 cm, and the cleared soil is piled up outside the cleared position and paved. According to the area and shape (100 cm wide square) on the border surface except for the soil removal area, cut the black one with a water permeability of 35.0L / s.m 2 , The ground cloth with a tensile strength above 860N is covered on the furrow surface. The cleared soil area around the blueberry tree is covered with the fertilizer formed by the mixed fermentation of 40% perlite, 52% fungus chaff and 8% rapeseed pod, and a layer of dry and fresh sawdust is covered on the top layer, a...

Embodiment 3

[0036] A method for suppressing the growth of weeds in a newly cultivated grape field of the present invention, the specific method is as follows:

[0037] Plow the cultivation land according to the requirements of viticulture, remove all weeds, apply basal manure, and ditch and ridge according to the row spacing. The width of the ridge is 80-100 cm, and the depth of the furrow is controlled at 40-50 cm. , Fill the nutrient soil in the cultivation hole, plant earthworms in it, and control the hole diameter at about 30 cm. Use black on the surface of the furrow block with a water permeability of 35.0L / s.m 2 , The ground cloth with a tensile strength above 860N is covered, and the furrow and furrow slope are covered with a PVC tarpaulin with a thickness of 0.3-0.4 mm. The edge of the black ground cloth is pressed under the tarpaulin, and piles are driven at the joint between the tarpaulin and the black ground cloth. Fix the tarpaulin and black ground cloth on the ground to ensu...

Abstract

The invention discloses a method for suppressing weed growth of fruit tree land. The method comprises the following steps: applying fertilizer containing no weed seed to fertilization areas of rest-balk block surfaces of the fruit tree land after weeds in the fruit tree land are cleaned up, coating non-fertilization areas of the rest-balk block surfaces with black ground cloth, and coating rest-balk furrows and rest-balk furrow slopes of the fruit tree land with tarpaulins, wherein the fertilization areas refer to areas of which the distances with fruit tree roots are not more than 100cm. According to the method disclosed by the invention, the fertilizer containing no the weed seed covers the fruit tree roots to play a dual role in suppression of the weeds and fertilization; the black ground cloth covers the non-fertilization areas of the rest-balk block surfaces to improve soil water permeability and air permeability, lower soil temperature and protect soil environment of fruit tree growth so as to facilitate the growth of the fruit tree roots and reduction of the cost; the tarpaulins cover the rest-balk furrows and the rest-balk furrow slopes, so that full-area coverage of the fruit tree land is implemented to prevent the weeds in rest-balk block peripheries from growing to rest-balk block areas, meanwhile, robustness and durability of the tarpaulins are utilized to achieve the effect of sustained weeding for multiple years by a one-time operation so as to reduce the labor cost of weeding operation.
