Rational fertilization is mainly based on organic fertilizer, supplemented by inorganic fertilizer. It should be applied sooner or later before mid-October to mid-November. Mainly based on decomposed farmyard manure, supplemented by chemical fertilizers. Generally, 3,000 to 4,000 kilograms of organic fertilizer per acre, 10 to 15 kilograms of potassium fertilizer, and 30 to 40 kilograms of phosphate fertilizer can be used to promote the germination of grapes.
Spraying protective leaves strengthens the prevention and control of diseases such as powdery mildew, rust and downy mildew. Combined with disease control, 0.3% urea plus 0.5% potassium dihydrogen phosphate can be used as root dressing, which can protect the leaves and promote the ripening of the branches, so that the leaves are normally physiologically defoliated.
After clearing the whole Qingyuan grape, the field and the rotten fruit and the deciduous diseased leaves will be completely removed, and the germination will be concentrated in the garden to reduce the source of the disease. After the clearing of the garden, the sulphur mixture of Bamei 3 to 5 degrees will be used for the surface and the ground. At the same time, it is sprayed and thoroughly cleaned.
Plastic trimming can adjust the tree structure of grape plants by plastic trimming, balance the relationship between branch growth and fruit growth, make the branches on the rack evenly distributed, and maintain good ventilation and light transmission conditions. For the plastic planting of the grape plant, it is generally selected after the natural leaves of the grape plant are started for 2 weeks. In the area where the soil is not required to be buried, the pruning time can be continued until the plant begins to grow in the second year.
Prevention and control of pests and diseases after pest control can ensure the growth of the tree body and reduce the source of the disease in the next year. White rot, downy mildew, anthracnose, etc. can be used alternately with carbendazim, methyl thiophanate and the like. After the winter cut, the branches will be cut out and taken out of the countryside. After 4 to 7 days, use 3 ° C ~ 5 ° C stone sulphur mixture to kill the insects once in the garden to eliminate the source of pests in the leap year.
