Why do grapes rot?
Grape rotten fruit is mainly caused by the damage of white rot, which occurs in the country's production areas. White rot is one of the important diseases of grapes. The fruit loss rate is generally 10-15%, and serious losses can be more than 60% or even lost.
White rot is a disease of high temperature and high humidity: it is most likely to occur at temperatures between 25-30°C; when the vineyards are poorly drained after rain, the soil is highly viscous, it is easy to form such diseases; the incidence of disease is generally in July-August Rainy season.
Precaution:
1. Variety selection: It is necessary to select varieties with strong disease resistance, high yields and popular markets.
2. The result is high: The vineyard with serious white rot must allow the grapes to be more than 50 cm above the ground, which can greatly reduce the incidence rate.
3, strengthen management: First, when the winter cut, completely remove the residual branches, residual fruit, burned in time; second, deep-turning soil in winter; third is to spray the new high-fat film diluent phase by stage from the bud to improve the body's absorption of water and fertilizer And use it to improve its ability to resist natural disasters and increase its tree potential. The fourth is scientific use of fertilizer, a reasonable amount of leaves and fruit retention, do a good job of drainage ditch clearance, timely weeding, improve ventilation and transparency, enhance plant resistance to disease.
4, isolation and disease. After the occurrence of white rot, it is generally not easy to cure, but methods such as isolating the disease can be used to cut the diseased fruit and the surrounding fruit together, so that the uninfected grape can be effectively protected.
5. Chemical control: In the early stage of disease, new fungicides such as azoxystrobin or azoxystrobin, pyraclostrobin, and new high-fat lipid film can be sprayed and sprayed once every 10 to 15 days to prevent and treat in rainy season. 3~4 times.
Pavement marking tape
Descriptions: Preformed reflective marking tape is embedded into micro reflective glass beads both on surface and body and has a durable,reflective and skid-proof effect. It's coated with special fiberglass reinforced ahesive, has super strong bond do different surfaces. It's designed to stripe asphalt parking lots,roads, bike paths and any other area where the road will subject to heavy traffic flow and high visibility delineation is needed. It has following features.1.Reflective marking tape takes double layer compound structure and is characterized by high skid-resistance, excellent reflective visibility, vibrant color and the like. Furthermore, it can be made into different kinds of marking belt, arrowhead, word, and pattern.
2. Both of these two types can be quickly and easily applied to clean, dry, asphalt or concrete surfaces
3. High retro.-reflectivity all day long, anti-skid, high tensile, strong weather resistance, easy application.
Performance Life:
The performance life of pavement markings will depend on the following:
Traffic conditions; Snow removal practices; Pavement surfaces; Application techniques.
It is recommended that each customer thoroughly evaluate our Pavement Marking Tapes under the conditions in the specified location. While experience has shown that when properly applied, these materials are highly effective traffic control devices, our Technologies makes no generalized performance claims.
