The prevention and treatment of grape sunburn

Hazardous features: When the fruit particles are sunburned, the fruit surface produces light brown near-round spots, the edges are not obvious, and the fruit surface first shrinks and then gradually sag, and the serious ear becomes a dried fruit. Tendons and shoots with young shoots that are not yet lignified can also suffer from sunburn injuries, causing tipping or wilting of the leaves.

Cause of the disease: Generally, infection occurs in the middle of June to early July (earing coloring and ripening period), and occurs mostly in the ears exposed to the sun. The reason is the lack of water in the tree and the lack of water supply in the fruit. When the water absorption in the root system is insufficient, the amount of leaf evaporation is large, and the osmotic pressure is increased, resulting in imbalance of fruit moisture, sunburn occurs. When roots or burning roots occur in the root system, sunburn may occur. Large grain varieties on the production are prone to sunburn. . In some cases, sunspots may appear in shades of the shoots and fruits as they are moved by cropping, toppings, and vines, or when the temperature suddenly rises.

Control methods: strengthen cultivation and management: appropriate deep fertilization, induce root groups to deeper development, increase tree vigor, and improve resistance to stress; appropriate dense planting, use scaffolding type, so that the ear is in a cool shade; prevent excessive waterlogging or over-fertilization Root phenomenon; in the high temperature onset of timely irrigation, adequate irrigation, evaporation, watering in a timely manner to reduce plant body temperature, avoid sunburn. Spraying and cooling: In the high-temperature weather after raining, apply 0.2% potassium dihydrogen phosphate solution or 5% ash leaching solution or 27% high-fat film emulsion 80-100 times to 2-3 times on leaves and ears. Has a certain preventive effect on sunburn.

Electric Over Blanket is similar to Electric Under Blanket, but a bit different.

Electric over blanket is used by covering human body to keep warm.

Normally electric over blanket is not recommended to be used during sleeping, as it might cause overheating, although it has the function of overheating protection.

Normally over blanket shuts off after 2 hours, for the sake of safety.
