Fast mature grape tube

When the grapes are ripe, more potassium fertilizer should be applied and phosphate fertilizer should be applied. Potassium fertilizer can use 0.3% potassium chloride or 0.4% -0.5% potassium dihydrogen phosphate, can also be used 1% of the ash leaching liquid foliar spray, the effect is good. If the load is too large, the yield is high, and the soil fertility is poor, fruit shrinkage will occur, and the ripening will be delayed. Therefore, appropriate topdressing of nitrogen fertilizer is still beneficial to improving the quality of fruits and promoting the growth of new shoots. At the same time, we must consider the fertility of the orchard and the climate characteristics of the year.

The ripening period of grape berry usually comes during the rainy season. Irrigation will affect the sugar content of the fruit, which will reduce the quality and cause the disease to spread. Low-lying plots tend to accumulate water during the rainy season, which is not conducive to grape maturation, and must be promptly drained after the rain to prevent flooding. All gardens need to be drained, but when autumn occurs in a special year, watering is still needed to ease the drought and ensure the normal maturation of the berries, but even Autumn drought does not water within 3 weeks before harvesting.
