1, base fertilizer vineyard fertilization in the most important part of the fall into, from the grape harvest to the soil before freezing can be carried out, practice has proved that the earlier the base fertilizer is applied in autumn, the better. Hedgerow garden can be opened in rows of 60 cm deep, 40?50 cm wide fertilizer ditch; trellis can be opened under the frame ditch, open ditch can not be too close to the tree, so as not to hurt the roots affect the growth. Per mu of rotting organic fertilizer 1500?3000 kg, with fast-acting fertilizers, such as "Mason" compound fertilizer 18-12-18 potassium magnesium sulfate 75?100 kg, a layer of fertilizer a layer of soil in order to fill the ditch. The amount of base fertilizer application accounted for 50?60% of the year, organic fertilizer should be applied in the base fertilizer in all.
2, soil fertilizer used in the growing season of grapes, generally 2?3 times per year. The first time in the early spring buds began to expand, when the buds are differentiating, the new slightly will soon begin to grow vigorously, you can choose "Mason" compound fertilizer 32-6-12, 34-0-16 for fertilizer, the youngest age, the youngest age, the youngest age, the youngest age, the youngest age, the youngest age, the youngest age, the youngest age. -16 fertilizer, young garden mu Shi 20?25 kg, adult garden mu Shi 40?50 kg; the second time in the flower after the early expansion of young fruits, the fertilizer can not only promote the expansion of young fruits, but also conducive to the differentiation of flower buds. You can choose "Meisheng" compound fertilizer 18-12-18 potassium magnesium sulfate, young garden mu Shi 30?35 kg? The third time in the early fruit coloring, can choose "Meisheng" compound fertilizer 18-12-18 potassium magnesium sulfate, young garden mu applied 20?25 kg? The adult garden Mu Shi 40?50 kg.
3, foliar spraying Foliar spraying can quickly supply the nutrients needed for the growth of grapes, generally can be divided into 4?5 times, the first time in the flowering period, to nitrogen and boron fertilizers (to promote the growth of new shoots and bud differentiation). Young fruit spray 2?3 times (to improve the fruit set rate), before July to nitrogen fertilizer, after July to phosphorus, potash fertilizer (to improve yield, improve quality), near ripening spray potash, calcium fertilizer and amino acids, rare earth foliar fertilizers (to improve the performance of storage and transportation). Spraying concentration should be 0.1%?0.5%.
