How to produce large-grain red grapes that meet export standards? This is a concern for the majority of red grape growers. In the past five years, Meng Peng, a member of the China Grape Association, has learned from the management experience of California Red Grapes, and according to the requirements for exporting large and large grains, he has explored and summed up a set of new technologies for exporting large grain reds. This new technology mainly uses plant-derived cell fission activators, anti-inverse antidotes "Chibao" and "Bao Mei Ling", non-ionic efficient penetrants, and amino acid high potassium nutrient solution "multiple liquids". This set of new technologies was promoted in Weinan, Xianyang, Baoji, and Tongchuan in Shaanxi, and was also promoted in red cultivation planting demonstration areas in Yili, Xinjiang, Korla, Qingyang, Gansu, Dunhuang, Shanxi Taiyuan, Linyi, and Yuncheng. Basically reached the start of 12 grams of red grape, the average grain weight of 16-18 grams. The fruit growers have tasted the sweetness of applying this new technology. In order to help the red grape growers increase economic efficiency, the application of this new technology is now described as follows.
First, promote Meng technology
1. Purpose: To promote neat buds, consistent flowering, and enhance frost resistance.
2, the use of time: in the spring of excavated branches, the end of the wound flow, bud balls exposed green.
3, the use of concentration: Qibao 15,000 times + Bao Mei Ling 7500 times + more than 500 times the liquid + plus 2000 times, 15 kilograms of water consumption.
4. How to use: Sprinkle wet shoots on the ground, focusing on the bud base.
Second, elongated ear technology
1. Purpose: To substantially reduce artificially sparsely growing fruits and vegetables, to lengthen the ear, and to create space for fruit enlargement in the later period.
2, the use of time: 10-14 days before flowering, inflorescence 7-10 cm long is the best time.
3, the use of concentration: Qibao 30000-40000 times + must add 2000 times + more than 500 times the suction.
4. How to use: Spray the entire plant's spikes, stems and leaves evenly and carefully.
Third, the key to increase the particle technology
First time
(1) Time of use: After the flower is completely thanked, the cap is removed and the particle diameter is 3-4 mm (ie, the size of the match head is large).
(2) Use concentration: Baomeiling 7500 times + more than 500 times + more than 2000 times.
(3) Usage: Spray all the branches and leaves and focus on the ear. If the cap is neat, it can be added 15000 times.
Second time
(1) Use time: One week after the first time, the diameter of the particles is 4-6 mm, such as when the margin bean is large.
(2) Use concentration: Baomeiling 7500 times + Shiqibao 10000 times + 2,000 times + more than 500 times more liquid.
(3) Usage: Focus on wet ear. Within 2-3 days, it is best to spray more than 500 times.
3rd, third time
(1) Use time: The best time is when the particle diameter is 12 mm.
(2) Use concentration: Baomeiling 7500 times + Qibao 10000 times + 2000 times.
(3) Usage: Focus on wet or soaked ears. The leaves can be sprayed with 500 times more liquid, 1-2 times. If you can top phosphate and potassium fertilizers, the effect is better.
Fourth time
(1) Use time: It is best when the particles are 14-16 mm long after the last maceration.
(2) Use concentration: Qibao 7500-10000 times + 2,000 times.
(3) Usage: Focus on wet or soaked ears. The leaves can be sprayed with 500 times more liquid.
After this spraying, it is recommended that every 5-10 days, the entire plant should spray more than 500 times until it is harvested.
Fourth, pay attention to matters
1, before the day of spraying more than 9 o'clock in the day, the next day after 5 o'clock is cool and cool without wind. Spraying is strictly prohibited at noon high temperatures.
2. Both Qibao and Baomeiling are active biological preparations. Once the solution is opened, it must be used within the same day. It cannot be used overnight.
3. There are two preconditions for the use of this technology: First, it is necessary to strengthen water and fertilizer management, apply more organic fertilizer and phosphorus and potassium fertilizers, and make the tree stronger. The second is to strengthen the prevention and control of pests and diseases, so as to ensure the protection of leaves and flowers.
