Recently, grape has ushered in the listing period one after another. At this time, grasping the pre-marketing management is the key to ensuring fruit quality. Song Taiyu, a senior agricultural technician, said that the management during this period was mainly divided into water and fertilizer management, pest management, and fruit management.
Water and fertilizer management and fertilization: nitrogen, phosphorus, and potassium compound fertilizers are the main components of the age-resulting trees. The ripening fertilizer is applied when the fruit is close to maturity, and is usually sprayed with 0.3% potassium dihydrogen phosphate solution or root fertilizers of phosphorus and potassium.
Watering: If the soil is dry, water it in time to prevent cracking. During fruit ripening, the soil moisture should be reduced, and the water holding capacity should be maintained at 50% to 60% to increase the sugar content and storage resistance of the fruit.
Diseases and pests management Diseases: Downy mildew can be sprayed with 68% gold or mildew 600 to 700 times spray; white rot and anthrax can be sprayed with 10% of World 2000 times or 50% of carbendazim 600 to 800 times. .
Insect pests: The grape-winged moth mainly damages the leaves. It controls the adult spawning and newly-incubated larvae to kill the shoots. It sprays once every other month and sprays three times. Pharmacy can be used for selective pyrethroid pesticides, such as 20% speed killing 2500 times; scarabs mainly harm the fruit, in the adult pest period can be sprayed pyrethroid pesticide 2000 times for control.
When the fruit management fruit reaches the size of peas, small fruit pieces, inferior mixed fruits, malformed fruit, disease and fruit, dense fruit, and damaged grains are eliminated. After rinsing, the granules were even and uniform, with 60-80 grains per panicle. After fixing and fixing the fruit, it is necessary to spray an insecticide to kill the insecticide. After the solution is dried, use a high-quality double-layer paper bag to timely bag it.
