Description

Technical Field

[0001] The invention relates to a method for preventing soil disinfection from harming grape trees when interplanting grapes and strawberries in a greenhouse, and belongs to the technical field of agricultural product and fruit planting. Background Art

[0002] In my country's greenhouse grape-producing areas, temporarily intercropping strawberries between rows of grapes for a single year is a common planting method. However, due to the serious problem of continuous cropping with strawberries, soil disinfection is necessary to maintain continuous strawberry cultivation on the same plot of land. While disinfecting soil in a facility where grapes are grown, soil disinfectants kill soil pests while also harming the grapevines. In mild cases, this can affect the normal growth and fruiting of the vines, while in severe cases, it can even kill the vines. Therefore, if intercropping strawberries with grapes in greenhouses is to become a sustainable, multi-year planting model, the harm to the grapevines caused by disinfectants during soil disinfection must be addressed. Summary of the Invention

[0003] In view of this, the present invention provides a method for preventing soil disinfection from harming grape vines when intercropping grapes and strawberries in a greenhouse, thereby preventing soil disinfectants from harming the grape vines when treating the soil.

[0004] A method for preventing soil disinfection from harming grape vines during intercropping of grapes and strawberries in a greenhouse, comprising:

[0005] S1. Building a single plastic greenhouse facility based on arch poles and central columns, and setting ventilation belts on both sides of the plastic greenhouse facility;

[0006] S2. In the plastic greenhouse facility, a horizontal grape trellis is constructed using the arch bars and center columns on both sides of the plastic greenhouse facility;

[0007] S3. Digging a planting ditch parallel to the plastic greenhouse facility on the inner sides of the left and right arch bars of the plastic greenhouse facility;

[0024] The present invention provides a method for preventing soil disinfection from harming grape vines during interplanting of grapes and strawberries in a greenhouse. The method avoids damage to grape fruits caused by exuded disinfectant gas by staggering the production of grapes and strawberries. The method improves the structure of the existing greenhouse and enhances the air circulation capacity in the plastic greenhouse facility, allowing harmful gases that may leak out during the disinfection process to dissipate in time. The method improves the structure of the grape racks in the greenhouse and keeps the grape branches and leaves as far away as possible from the soil that needs to be disinfected, thereby reducing damage to the grape branches and leaves caused by exuded disinfectant gas. Furthermore, the method rationally arranges the spatial arrangement of the grape vines and strawberry seedlings to create favorable conditions for the roots of the grape vines to grow outside the plastic greenhouse facility, thereby preventing overall damage to the grape root system caused by the disinfectant during soil disinfection. The method also removes the sealing layer in batches after the soil disinfection process is completed, thereby preventing a single large-scale release of exuded disinfectant gas, thereby reducing damage to the grape branches and leaves caused by the exuded disinfectant gas. The combined use of the above measures solves the problem of damage to grape vines growing simultaneously in the plastic greenhouse facility caused by the disinfectant during multi-year interplanting of greenhouse grapes and strawberries and soil disinfection in the strawberry planting area. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 The present invention is a flow chart of a method for preventing soil disinfection from harming grape vines when intercropping grapes and strawberries in a greenhouse. DETAILED DESCRIPTION

[0026] The present invention is described in detail below with reference to the embodiments, but the present invention is not limited to these embodiments.

[0027] like Figure 1 As shown, the present invention provides a method for preventing soil disinfection from harming grape vines when intercropping grapes and strawberries in a greenhouse, comprising:

[0028] Step 1: Build a single plastic greenhouse facility based on the arch pole and the center column, and set ventilation belts on both sides of the plastic greenhouse facility;

[0029] Among them, the shoulder height of the plastic greenhouse facility is 2.2m (set within the range of 2.1-2.3m), and the width of the plastic greenhouse facility is less than 10m; the length of the ventilation belt is the same as the length of the plastic greenhouse facility, and the width of the ventilation belt is greater than 1.5m. By improving the ventilation conditions of the plastic greenhouse facility, the subsequent disinfection of the planting soil of the strawberry seedlings is conducive to the timely dissipation of the infiltrated harmful gases and discharge from the plastic greenhouse facility, thereby avoiding the infiltrated gases from causing damage to the branches and leaves of the grape vines.

[0030] Step 2: In the plastic greenhouse facility, use the arch poles and central columns on both sides of the plastic greenhouse facility to build a horizontal grape trellis. The height of the horizontal grape trellis is greater than 1.8m, so that the branches and leaves of the grape vines are away from the ground, further avoiding the damage caused by the infiltration of soil disinfectant gas to the branches and leaves of the grape vines.

[0031] Step 3: Inside the plastic greenhouse facility, dig a planting ditch parallel to the extension direction of the plastic greenhouse facility on the inner side of the arch rods on the left and right sides of the plastic greenhouse facility; the horizontal distance between the planting ditch and the arch rod is 30 cm, the depth of the planting ditch is greater than 70 cm, and the width of the planting ditch is greater than 60 cm, which can create favorable soil conditions for the downward growth of the roots of the grape vines.

[0032] Step 4: Planting grapevines in the planting furrows can create favorable conditions for the roots of the grapevines to grow deep into the soil layer and out of the plastic greenhouse facilities, and can also provide as much land area as possible for planting strawberry seedlings, so that the strawberry seedlings are planted between the two planting furrows, and the planting cycle of the strawberry seedlings is from early September of each year to mid-April of the following year; wherein, the grapevines are selected from very early-maturing grape varieties or early-maturing grape varieties, and the main vines of the grapevines are set on the trellis surface of the horizontal grape trellis, so that the leaf curtains and fruits of the grapevines all grow on the trellis surface of the horizontal grape trellis, which can reduce the damage of the exudate gas to the branches and leaves of the grapevines when the soil disinfectant is used.

[0033] Step 5. After the grape fruits are picked each year, the soil in the strawberry planting area is disinfected. The grape fruit picking period is before mid-July each year to achieve staggered management of grapes and strawberries. The soil disinfection time in the strawberry planting area is from 15 days after the grape fruit picking to early September of the same year, which can create conditions for the grape vines to recover.

[0034] Step 6: When disinfecting the soil in the strawberry planting area every year, keep a distance of 45-55 cm between the disinfected area and the main trunk of the grape vine.

[0035] Step 7: After the disinfectant is applied to the soil, the disinfection area is covered and sealed, and all ventilation belts are placed in the maximum ventilation state during the disinfection process. After the disinfection is completed, the sealing layer is removed in batches; among them, after the soil in the strawberry planting area is disinfected, the sealing layer is removed at least twice, and the interval between the removal of two adjacent sealing layers is greater than 5 days.

[0036] Specifically, in this embodiment, the specific operations for soil disinfection in the strawberry planting area include: first, the disinfection area is 50 cm away from the main trunk of the grape vine (set within the range of 45-55 cm) to reduce the damage to the roots and main trunk of the grape vine when the soil disinfectant is used; then, the soil that has been used with the soil disinfectant is covered with a sealing layer, so that during the soil disinfection treatment, the treated soil is in a fully sealed state, reducing the infiltration of the soil disinfectant, and at the same time, the ventilation belts on both sides of the plastic greenhouse facility are completely open to create the best possible conditions for air circulation, so that harmful gases that may infiltrate can be dissipated in time; the sealing layer can be selected from ground film or greenhouse film and used alone, or the ground film and greenhouse film can be superimposed on each other and used; after the soil is disinfected, the sealing layer is removed twice or more, and the time for removing the two adjacent sealing layers is greater than 5 days, so as to reduce the amount of harmful gases infiltrated from the soil after each film removal, so that the infiltrated harmful gases can be discharged from the plastic greenhouse facility in time.

[0037] In the present invention, grape and strawberry production are staggered to avoid damage to grape fruits caused by seepage of disinfectant gas; the structure of the existing greenhouse is improved to enhance the air circulation capacity in the plastic greenhouse facility, so that harmful gases that may seep out during the disinfection treatment can be dissipated in time; the structure of the grape rack in the greenhouse is improved to keep grape branches and leaves as far away as possible from soil that needs to be disinfected, thereby reducing damage to grape branches and leaves caused by seepage of disinfectant gas; and, grape trees and strawberry seedlings are rationally spatially arranged to create favorable conditions for the roots of the grape trees to grow deep into the soil layer and out of the plastic greenhouse facility, thereby avoiding overall damage to the grape root system caused by disinfectant during soil disinfection treatment; and at the same time, the sealing layer is removed in batches after the soil disinfection treatment is completed, thereby avoiding a single large-scale release of seepage of disinfectant gas, thereby reducing damage to grape branches and leaves caused by seepage of disinfectant gas.

[0038] By using the above measures in combination, the problem of damage to grape vines growing simultaneously in the greenhouse caused by disinfectants during soil disinfection in the strawberry planting area when grapes and strawberries are intercropped for many years in the greenhouse can be solved.

[0039] The above descriptions are merely several embodiments of the present invention and do not constitute any form of limitation to the present invention. Although the present invention is disclosed as above in terms of preferred embodiments, they are not intended to limit the present invention. Any technician familiar with the present profession who, without departing from the scope of the technical solution of the present invention, makes slight changes or modifications using the technical contents disclosed above are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
