Grape maturity management
1. The varieties of grapes picked in batches at different times are different. The maturity period is also inconsistent. Different measures should be taken according to different circumstances when picking. The mature grape surface has a shiny, transparent flesh with a thick layer of powdered cream. The taste of the food is tan. If the picking is too early, the acidity will be too high and the quality will be affected. If the picking is too late, the fruit will be very light and it will not be able to be stored and transported. Therefore, timely picking and batch processing are the key to ensuring grape quality. It's best to pick out after sunny morning dew. 2. Pay attention to drought prevention and cooling In the harvesting stage, in the event of long-term high temperature or no rain, fruit and leaves are easy to shrink, affecting plant growth and flower bud differentiation. Therefore, we can use the grass between the rows to reduce the ground temperature, and pay attention to timely and appropriate irrigation. Irrigation should adopt a ring-shaped furrow irrigation method, that is, digging a wide ditch around the canopy and pouring water into it. 3, timely application of "slim" fat grape ripening stage, it is the root growth of the second peak period, timely fertilization. This fertilizer accounted for 60% of the total fertilization for the whole year; fertilizers such as manure, compost, and pond mud are preferred. At the same time mixed with some urea, ammonium bicarbonate and other fast-acting fertilizers. Each acre of vineyards requires 3000-4000 kg of organic fertilizer, 30-40 kg of urea or 100-130 kg of ammonium bicarbonate. Fertilizer is applied first, organic fertilizer is applied first, then cover soil, and timely irrigation after fertilization. In addition, the trimming of the shoots should be stopped during the ripening period.
