Reason: The land conditions in the vineyard are too poor, the nutrient supplement is not timely; the uncoordinated ratio of leaf and fruit leads to insufficient nutrient supply; the grape harvesting period needs the daily scientific care of boron and calcium to cause the deficiency.
Key points: Spraying foliar fertilizer from the spring and strengthening the daily management of the orchard can avoid the phenomenon of grape grain softness.
Measures: 1. After the summer, choose the wind-free and rain-free evening in the growing season, spray the leaf surface fertilizer with the grape leaf back shoots, take the medicine and fertilizer mixed spray with the new high-fat membrane mixed spray to control the volatile evaporation of the pesticide and prevent the rainwater from scouring. Enhance fertilizer efficiency and increase the control effect.
2. Scientific fruit control to control the load of vines, maintain a certain ratio of fruit to leaves, generally 22 leaves of a panicle is better, and pay attention to the selection of appropriate fertilizer application.
3. After 10 days of flowering, spray the strong fruit fertilizer and apply 500 grams of compound fertilizer to each plant. After spraying, watering the cover and spraying the grape on the leaf surface can promote the growth of young fruit and effectively increase the fruit. Invigorating vitality and achieving the effect of increasing production.
4. Apply nitrogen fertilizer after harvesting to prolong the life of the leaves, increase the nutrient storage of the tree, and apply nitrogen and post-harvest nitrogen supplementation after harvesting.
