The non-nuclear cultivation of grapes is based on the combination of good viticulture techniques and the treatment of grapes without twigs to soften or abrogate the fruit of the original large-grained grape fruit, making it large-grained, early-maturing, seedless, and productive. High-quality, disease-resistant purpose. The effect of using grapevines is: 1. High coreless rate and correct use of 100% coreless rate. 2. Mature dry can be matured 7 to 10 days earlier than conventional cultivation under the same yield. 3. The fruit set rate of high spike setting percentage was about 95%. 4. The quality of the non-nucleated grape was low, and the taste of the fruit was significantly better than that of conventional cultivation. The sugar content of the fruit was 2 degrees higher than that of conventional cultivation. 5. The increase in output can obviously increase production by 30-40% under the next normal year. 6. Commercial high-treating ears have beautiful ear shape, tight spikes, uniform particle size, no granules, and maturity. 7. The disease resistance of the plant is stronger than that of conventional cultivation. The ear is basically disease-free and the branch can mature 7-10 days earlier. The biggest difference between the techniques of denuclearized cultivation of grapes and conventional cultivation techniques is that conventional cultivation requires tree vigor and high fruit setting rate. No branching cultivation does not require pollination, but it requires sufficient tree nutrients and strong tree vigor. This can ensure high fruit setting rate, high seedless rate, too fast fruit filling, and early maturation. Before the use of non-nuclear penalties, production and management must be performed according to the denuclearization cultivation technical indicators, otherwise the use of non-nuclear agents will not be effective. One, non-nuclear agent treatment method Nuclei agent treatment can be divided into two treatment methods and one treatment method. The first treatment of the two treatment methods is from 3-7 days before the first flowering to the first flowering. The second treatment is 3-5 days after the 90% flowering (ie the fruit is sorghum grain Large-time) processing, generally with the first processing interval 7-10 days. One time treatment method 90% after flowering 10 days after flowering. Compared with the two treatment methods, the one-time treatment method was more resistant to storage and transportation, and the fruit was larger than the two treatments, but the taste was slightly worse than that of the two treatments, and the total yield was lower than that of the two treatments; the non-nuclear rate of one treatment was less. Up to 90-95%, two-time non-nuclear string up to 100%. Second, the application of non-nuclear agent treatment technology on grape plant management requirements 1 production capacity of 1500 kilograms per year of suburban gardens, more than the top date of the purpose. 2. The remaining amount of ribs leaves 11 sticks per plane. Does not include renewal shoots of budding buds. That is, 1 meter long main vine leaves 5-6 branches, leaving 2 branches in each of 3 branches and 1 branch as vegetative branch. 3. The amount of fruit left 15-20 seeds per plant, single panicle weight to 750 grams -1250 grams is better. 4. Leaf retention leaves (strong twigs) were picked up 3 to 5 days before flowering. The best leaves for each leaf were guaranteed 9-lo slices, with an average of 22 leaves for the growth of 1 ear. All kinds of branches on the axillary shoots left a leaf 'topping heart, the top of the top of the sub-tip to leave 2-3 leaves topping heart, all the secondary shoots occurred after the eradication. 5. Ear plastic surgery About 3 days before treatment with a non-nuclear agent, the inflorescence cut from the tip of the spike to 1/3 to 1/4 of the whole panicle, and the tendril and deputy panicle were all removed. 6. Fertilization can be simplified to two top dressings. The first time after the grapes are ten, when the soil temperature is 10-20 centimeters, the soil temperature is stable at 12 degrees, and the available N fertilizers, such as urea and ammonium nitrate, are 50-75 grams per plant. , 50 grams of potassium sulfate, phosphorus gram grams; the second time in the end of June - early July application, no nitrogen fertilizer, phosphorus, potassium fertilizer with the first time. Something may be applied as usual 5-6 times fertilizer. 7. Pruning was performed using dragon dry shaping, short tip pruning (2-3 buds per branch), and branch group culture combined with single branch regeneration and double branch regeneration. With the above management methods, the fruit set rate can be high, the seedless rate is high, and the spikes are tight; no size, early maturity.
