(Correspondent Li Fangfang) In spring plowing season, the most important agricultural material purchased by farmers is mulch. Plastic film used for agricultural ground cover can not only increase ground temperature, water, soil, fertilizer and improve fertilizer efficiency, but also kill weeds, prevent diseases and insects, prevent drought and waterlogging, inhibit salt and protect seedlings, improve near-ground light and heat conditions, etc. Features. However, if the purchased mulch product is unqualified, it will cause devastating losses to the crop. It is important to choose a good mulch film.

A farmer in Emin County, Mr. Zhang, bought 430 pieces of agricultural mulch film at an agricultural material shop, and planted 1,350 mu of corn. However, after the seedlings emerged, a wind blew, and the mulch was rotten by the wind, causing the drip irrigation belt to become a mess. All were damaged and the economic loss was serious. Zhang found Xinjiang Zhenguanda Agricultural Technology Co., Ltd. for loss identification.
The company assigned appraisers Chen Jinmei, Hasyetti Husayin, and Chang Shijuan to form an appraisal team to conduct on-site inspections and investigations on the appraisal site. Chen Jinmei, an agricultural technology extension researcher of the company, said that the corn mulch film involved There is a causal relationship between serious damage after encountering strong wind and unqualified mulch film quality.
So how to choose a mulch that is not easy to rot? Chen Jinmei said: At present, there are many types of mulch film on the market, and the quality is uneven. Farmers should pay attention to the following points when choosing mulch film:
1. According to national regulations, the thickness of the mulch film is 0.014 mm, the micro film is 0.008 mm, and the ultra-micro film is 0.005 mm. The use of mulch film below 0.008 mm is strictly prohibited.
2. Pull and test the mulch repeatedly. A good mulch film has good horizontal and vertical tension. Cut a small strip of mulch film, and it can be stretched 2-3 times when stretched without breaking.
3. Poke the hole with your hand. If the hole is round and has burrs, it means that the longitudinal and transverse tensile forces of the membrane are the same.
4. To purchase mulch, you must understand the qualifications and reputation of manufacturers and sellers, and inspect product quality inspection certificates and sales invoices.
Geogrid
The Geogrid including Polyester Geogrid, Fiberglass Geogrid, Steel Plastic Composite Geogrid and Plastic Geogrid.
The geogrid is a major geosynthetic material. Compared to other geosynthetic materials, it has unique performance and efficacy. Commonly used for reinforcement of soil structure or reinforcement of composite materials.
The uses of geogrid: It is suitable for embankment and embankment reinforcement slope protection tunnel wall reinforcement large airport parking lot wharf cargo yard and other permanent bearing foundation reinforcement.
The feature of geogrid:
The high strength creep can adapt to all kinds of environment soil, and can satisfy the use of high grade highway retaining wall.
It can effectively improve the locking and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.
More suitable for deep-sea operations, embankment reinforcement, fundamentally solve the other materials do stone cage due to long-term erosion by the sea caused by low strength, poor corrosion resistance, short service life and other technical problems.
It can effectively avoid the construction damage caused by the crushing and destruction of machinery and tools in the construction process.
