How to plant a good table tennis grape
Fujisawa vines have an average grain weight of 18-25 grams and a maximum grain weight of 40 grams. They are larger than table tennis and are therefore known as table tennis grapes. It is famous for its large scale, early maturity, high yield, and delicious taste. It has won 8 domestic gold medals and international gold medals, and has passed the acceptance of the National Spark Plan project. According to incomplete statistics, there have been tens of thousands of households with annual income of over ten thousand yuan in planting Fujiminto grapes, of which nearly 100 are farmers with annual income of over 200,000 yuan. The promotion of Fujiminori grape has become an important way to develop "two high and one excellent" agriculture in many areas and help farmers increase their income. To grow good Fujiminori grapes, to ensure that the fruit is large, high quality, high yield, high efficiency, cultivation and management must pay attention to grasp the following important links. New shoot management? Buds, shoots, toppings, and sub-shoots? Wipe off weak shoots and double buds in time after snow germination. When the inflorescence became apparent, it began to set the tip, eradicating the dense and stunted branches early, leaving strong branches so that large-grained grapes could grow. Topping should be done when there are 4 to 8 leaves on the inflorescence. After topping, except for the top apical shoot, 3 to 4 leaves were repeatedly picked and the rest of the auxiliary shoots left only 1 leaf topping. In order to control the production of grapes with large fruits and thin fruits for table tennis, the yield per acre must be controlled between 1,500 and 2,000 kilograms, and each strong branch can only retain one spike. One to three weeks before flowering, the spindles of the panicles and spikes were sparse and 3 to 6 spindles were removed. At the beginning of the flowering period, the tips of the spikes, 1 to 2 cm long, were removed. Immediately after the fruit set, the fruits should be thinned, and about 30 grains of fruit should be left in each ear. The fertilization will be poor, and the fruit protruding out of the fruit in the middle of the ear will be completely discarded, leaving the fruit with good fertilization and oval shape. Hormone treatment using grape swelling agent can increase fruit size by 20% to 50%, and the processing time is about 20 days after flowering. On sunny days, fruit picking should be carried out after 3:00 pm. It should not be soaked at high temperatures at noon. If rain falls within 6 hours after fruit dipping, the effect will be reduced. The management of fertilizer and water to create good fertilizer and water conditions is a guarantee for a good variety of large table tennis grapes. The correct approach is: after the fall, plunge the soil, apply 2500 kg of farmyard fertilizer and 100 kg of compound fertilizer per acre; apply 1 quick-acting nitrogen fertilizer 1 week before germination, apply 15 kg per acre; combine irrigation for 1 week after flowering Mushi 15 kg of compound fertilizer and 10 kg of potassium chloride, spraying 0.2% potassium dihydrogen phosphate two times at the same time; applying 30 kg of compound fertilizer per acre after fruit harvesting to restore the tree vigor. Disease Prevention and Control In the winter clearing garden, 1% of sodium pentachlorophenol was sprayed on the stems and the ground for thorough disinfection. The winter buds sprouted in the spring before they were green, and then sprayed with 0.5% sodium pentachlorophenol for disinfection. Spray bactericide to prevent blackpox before rain and after rain. In addition, the use of grape swelling agent after the whole bagging of the ear, can effectively prevent anthrax.
