What are the benefits of using grass-proof cloth on a large area in the dragon fruit base?

In recent years, as the demand for dragon fruit has continued to rise, the price has risen all the way, and the planting area of ​​dragon fruit has continued to increase, and large-scale dragon fruit bases have continued to emerge in several southern provinces. What follows is the problem of weed treatment in the dragon fruit base. As consumers are more sensitive to the drug residues of fresh fruits, the method of spraying herbicides has long been abandoned in the treatment of weeds, but artificial The cost of weeding continues to rise and the efficiency is low, and the emergence of grass-proof cloth has just solved this problem. Weed-proof cloth mulch has become the first choice for many dragon orchards to control weeds. Although its initial investment is relatively high, one-time investment will benefit for many years. Recently, the National Intermediate Agronomy Teacher of Shouguang Caiyuan Plastic Industry Co., Ltd. was invited to analyze the application characteristics and precautions of grass cloth for the dragon fruit people.

The cultivation of dragon fruit on hundreds of thousands of acres of land is nothing new in the south. However, the large-scale planting of dragon fruit will also face a sharp increase in the cost of various planting links, including labor, fertilizers, pesticides, equipment, etc., which require more scientific and more refined management and use to effectively improve economic benefits.

Weeds are one of the important factors that endanger the growth of dragon fruit. Weeds will not only snatch pitaya fertilizer, but also provide parasites for various pests. At present, most of the small pitaya bases in my country use artificial weeding and chemical (herbicide) weeding, and some bases use plastic mulching weeding technology.

However, the labor and material resources of artificial weeding are relatively large; the cost of chemical (herbicide) is low, but long-term use will cause environmental pollution, destroy the ecological balance, and affect the yield and quality of agricultural products; the cost of mulching weeding is low, and there is ventilation in practical applications Poor performance, resulting in damage to the roots of some crops, and the mulching film is easy to tear and difficult to degrade, with low recycling rate and short service life.

The widespread use of grass-proof cloth in the dragon fruit base has been the past two years. Weed-proof cloth, also known as weeding cloth, gardening ground cloth, etc., is woven from narrow strips of polypropylene (PP) or polyethylene (PE) material, and is specially added with anti-aging agents such as anti-ultraviolet rays. The color is mainly Black, as well as white, green, brown, etc. It has the characteristics of abrasion resistance, UV resistance and mildew resistance.

Now the grass-proof cloth used on the dragon fruit base is mainly black, preferably 18-2 mesh. Compared with other covering materials such as mulch film, the grass-proof cloth has good water permeability, good air permeability and good moisture retention effect. It can effectively inhibit weeds for a long time, thereby reducing production costs, improving production efficiency, and improving crop quality and yield. Production has important value.

The following is a simple summary of the advantages of using grass-proof cloth:

1. Control weeds

The grass-proof cloth can block the photosynthesis of the grass by shading, and realize the physical weeding without damaging the roots. It can solve the problem of weeding for three years by laying it at a time. Especially in hilly and mountainous areas, where the ground is uneven and there are many stones, it is difficult to realize weeding measures such as mulching film, growing grass, and artificially. The grass-proof cloth shows great advantages in controlling weeds.

2. Maintain soil moisture

The grass-proof cloth mulch hinders the vertical evaporation of soil water, increases the resistance of water evaporation, allows water to migrate horizontally, and effectively inhibits the ineffective evaporation of soil water. Under the condition of no precipitation, the mulching with grass-proof cloth can effectively increase the soil moisture content in the soil layer at 5cm, 20cm and 40cm by about 13-15%.

3. Prevent the loss of water, soil and nitrogen

Soil nitrogen, especially inorganic nitrogen, exists in a large amount in the soil solution. When the rainfall is large, surface runoff is formed under the washing of rainwater, nitrogen is lost with the runoff, and the soil is also severely eroded. Slope land with high vegetation coverage can effectively reduce soil erosion due to root fixation, but a large number of weeds and other vegetation in cultivated land are removed, and soil and water are easily lost. Laying grass-proof cloth can avoid the direct erosion of the soil by rainwater, maintain the water and soil, prevent the loss of nitrogen, and protect the ecological environment.

Fourth, keep the ground clean

The grass-proof cloth has enough water permeability to ensure that the accumulated water on the ground is discharged quickly in rainy days, prevents rainwater from accumulating on the surface of the grass-proof cloth to form puddles, and also avoids muddy, so as to keep the ground clean after rain, which is convenient for walking and working.

5. Improve nutrient utilization

In agricultural production, the use of grass-proof cloth can maintain proper plant rhizosphere soil moisture, promote root development, and help crops absorb nutrient elements in the soil. At the same time, the suppression of weeds by the grass-proof cloth greatly reduces the competition for soil nutrients by weeds, so that crops can obtain more sufficient nutrients.

Six, pest control

In agricultural production, many pests use weeds as their habitats. The use of grass-proof cloth can effectively control weeds and reduce the source of pests and diseases. The use of wed-proof cloth can also effectively control the pests that live in the soil such as moths, reduce the application of pesticides, help increase crop yields, improve the safety and commercial properties of agricultural products, and meet the country’s need to create vegetable, forest and fruit standard gardens. Production demand. Compared with mulching film, grass-proof cloth has better air permeability and can effectively avoid root rot in the use of mulching film.

7. Increase crop yield

The use of weed-proof cloth for weeding in agricultural production provides a suitable growth environment for crops, and greatly improves the utilization of nutrients, which is conducive to the improvement of the quality of crop products and the increase of yield.

8. Low cost of comprehensive weed control

The service life of grass-proof cloth has always been our most concerned issue, and the length of service life is related to the final use cost. Generally speaking, the service life of grass-proof cloth varies from 3-5 years depending on the material (new material or recycled material), climate, light, etc. From the perspective of use and environmental analysis, its service life can be divided into two types: outdoor use and indoor use in greenhouses:

Open-air use: 3 years to 5 years. This kind of weed-proof cloth is generally used in open-air economic crops or orchard planting. Due to long-term outdoor wind and sun, the anti-aging ability will be greatly reduced.

Indoor use in greenhouse: 5-8 years. Because it is used indoors, it is the opposite of outdoor use. The influence of sunlight and wind is very small, and the anti-aging ability will be fully displayed. The minimum service life is 5 years.

Precautions for use:

If you don't put the grass cloth on the ground, everything will be fine. If you don't do it well, the effect will be discounted. Use grass-proof cloth on a large area of ​​the dragon fruit base. After laying, the two sides should be compacted with soil, the joints should be overlapped 5-10 cm, and fixed with ground nails or other materials every 1 meter, and pay attention to regular inspections to ensure that the edges are firmly fixed , To prevent being lifted by strong winds; to control rodents and other small animals infestation, to prevent the weed cloth from becoming its habitat, thereby harming plants and fruits; to keep the surface of the weed cloth free of soil to prevent weeds from growing on the surface of the weed cloth and rooting Penetrate damage to the fabric; manually pull out the weeds at the opening of the grass-proof fabric.
