1, planting red grapes, it is appropriate to choose fertile deep sandy loam or loose loam, ph value of 6,5 ~ 7,5, irrigation and drainage is excellent; seedling planting or direct insertion (seed strips) to build a garden, it is appropriate to hold a plant spacing of 1 m ~ 1,5 m, row spacing of 4 m ~ 5 m of small trellis planting; and hold a dragon stem-shaped pruning.
2, after planting, pay attention to watering and fertilization, into the efficacy of the period, to flood large fertilizer. As usual, the efficacy of the period of 5,000 kilograms of soil fertilizer per mu per year, and insert 500 kilograms of calcium sulfate. Annual fertilizer 3 times ~ 4 times, as usual before the bud (urea or diammonia 20 kg / mu), after the fruit (nitrogen fertilizer 20 kg / mu), fruit expansion period (potash 20 kg / mu), 20 days after harvest (three elements of compound fertilizer 20 kg / mu); each fertilizer unity watering, 20 days before the picking of water, the drought area, pay attention to watering the freezing water and water for sprouting. Another appropriate multiple extra-root fertilizer, starting in mid- to late August every 15 days unity spraying 0, 3% to 0, 5% urea, potassium dihydrogen phosphate or trace elements to promote fruit and branch maturation; ripening before the avoidance of spraying ethylene and other ripening production conditioners, or the fruit is not in good shape.
3, red grapes flowers and fruits pointing is the primary thinning inflorescence and fruit spike. Too large spikes, too small spikes, heteromorphic spikes should be held to remove, each spike as usual no more than 1000 grams per mu to maintain 2000 kg ~ 2500 kg is appropriate. Followed by centering and tying, the spikes should be liquidated, too long spikes should be pinched tip, so that the spikes neat and equal, the presentation of the second spikes should be removed in real time, and small grains, deformed also sparse, so as not to squander the nutrients. Fruit bean grain size when the bag, 1 week to 2 weeks before harvest to tear the bag in the lower part of the warping, in order to promote coloring.
4, the red mention because of the development of large quantities, it is appropriate to recover the trellis single stem double-armed shape pruning, short tips or short tips _ miscellaneous pruning. Planting of the previous development potential of good grapes can be cut to stay 2 ~ 3 full buds held flat stubble, the second year delayed vine is still 1 meter ~ 1, 5 meters long cut. Each plant to stay a main vine, each meter long main vine to save 3 to 4 efficacy branches, the former new shoots up to 30 cm to 40 cm when set the end of the tied trailing, to maintain 6 to 7 new shoots, of which there are 3 to 4 fruits, 2 to 3 for the nutrient branches. The center should not be too early, due to the variety of the center, the second and third tip of the development of weak, small leaves.
5, red grapes disease resistance is a little poor, the disease is mainly including mildew, black pox disease and anthracnose, insect pests are mainly red spider, aphids and so on. In order to "prevention-oriented, integrated prevention and control" of the basic, to real-time spraying prevention and control, especially in the rainy season to pay more attention to abnormal. The early spring of 5 degrees of stone sulfur is very important, pre-spray two half-volume Bordeaux solution, are the key method to prevent black pox, gray mold. After the fruit should pay attention to the control of white rot, anthracnose and other diseases. Every 10 days to 15 days, according to the morbidity environment, choose to spray equal amount of Bordeaux liquid or Kobo or Dasheng-M45 or Fumitsu or Fumitsu liquid, can also be used Bordeaux liquid or Fumitsu or Fumitsu liquid alternately to organize the spraying to prevent and control a variety of diseases. Later to pay attention to the prevention and control of downy mildew, can be sprayed with 40% aluminum diphosphate agent 200 times to 300 times liquid or 25% of the mefenamic acid 600 times liquid, such as heavy disease can be sprayed again every 5 days to 7 days.
6, red picking in batches, should not be picked in advance, or not only low sugar poor quality, and intolerant of storage. After picking real-time boxing, low-temperature career. After picking base fertilizer, watering, buried soil cold.
