After the spikes are adjusted, the spikes are clearly elongated. Before or after sunny noon, the deputy panicles are removed and the spike tips are removed. Approximately one-fourth of the ear length is eliminated to concentrate nutrients, increase fruit setting rate, and prevent loosening of the ear. When the young fruit grows to the size of the soy bean, it is necessary to remove small and dense grains in time and increase the uniformity of the fruit.
After the ear of flowers has been flowered, ears can be treated with 25-50 mg/kg gibberellic acid solution or 10 mg/kg grape special swollenin liquid solution at the flowering stage and about 10 days after flowering.
The specific method is: use a wide-mouth container to hold the liquid, and then dip the whole grape into the liquid. The peony should be taken before 10 o'clock in the morning or after 3 o'clock in the afternoon. After this treatment, it can promote grape fruit enlargement, mature about 5 days in advance, and increase the rate of seedlessness.
The new shoots on the tied vines are about 30 centimeters long. When the base is semi-woody, the vines must be tied at the right time. When putting on the shelves, it is necessary to perform detailed operations to prevent damage to spikes and shoots, and to arrange them evenly. With a "8"-shaped buckle of fiber knots, the new vines will be fixed on the iron wire. When the new vine grows, it is fixed on the second and third wires in multiple stages. When tying vines, it is important to note that the vines must not be tied upright. They must be in the same direction as the wire and obliquely placed on the shelves. They are arranged in a large “s†shape.
After the summer shoots have been adjusted and the results have been picked up, the shoots of the summer shoots can be sprouted (secondary shoots). The result is that the two shoots are tipped, leaving 4 leaves to pick the heart, and the remaining summer shoots are all erased. . The second shoot shoots a secondary shoot again (three new shoots), leaving only one top shoot, leaving 4 leaves topping and all other wipes. After four new shoots or multiple new shoots, they are still treated in this way.
Before topdressing and watering facilities begin to heat up, they should be poured once. Afterwards, watering should be properly controlled to reduce injury and help strong seedlings. After the winter buds germinate, when the shoots reach 5-10 cm in length, they can be poured under the mulch, combined with watering, and topped with 50 kg/mu of organic fertilizer. Watering should be done on a sunny day in the morning, and the tuyere should be properly vented to prevent disease. When young fruit grows to the size of mung bean, it can lift the mulch between rows, excavate a 20-cm deep fertilization ditch, and chase the decomposed manure 1000kg/mu + potassium sulfate 20-30kg/mu. note. Every time watering and topdressing should be done in the early morning of the sunny day and open the tuyere operation, it should be carried out in an interlaced manner. After 3-4 days, the remaining rows should be watered and fertilized.
After germination of the top dressing, one week before flowering, 7-10 days after flowering, and the young fruit expansion period, the combination of disease prevention and insect repellent administration is required. Spray 300 times Guouoan + 150 times brown sugar + 250 times potassium nitrate + 400 times glucose. Calcium acid + 300 times magnesium sulfate + 5000 times organic silicon mixture improves the drought resistance, antifreeze, and anti-drug resistance of grapes, enhances photosynthetic efficiency, promotes new roots, and improves fruit setting rate, yield, and quality. After the fruit grows to the size of soybean, in order to increase the yield and quality, it is necessary to strengthen the top dressing and combined with prevention and treatment. Spray 250 times potassium nitrate + 100 times fermented milk + 400 times calcium gluconate + 300 times magnesium sulfate every 10 days. +300-500 times the amount of tea saponin + 5000 times the silicone mixture, sprayed 3-5 times.
To increase the yield and quality of grapes by adding carbon dioxide gas fertilizer, from the time of flowering to the ripening of grapes, carbon dioxide gas fertilizer should be added at about 9:00 am every day.
