Grape Standard Demonstration Park Management Experience

1. Re-applying organic fertilizer, growing season auxiliary compound fertilizer

The park is heavily invested, and fertilization is still not sloppy in the case of high fertilizer prices. After harvesting in autumn, timely application of 2,000 tons of decomposed chicken manure + 100 kg of crop straw + 100 kg of lotus brand compound fertilizer + 50 kg of urea; 100 kg of compound fertilizer before harvesting in the next year of germination; 25 kg of urea; fruit expansion period and coloring period Apply 50 kg of compound fertilizer + 50 kg of potassium sulfate. In addition, foliar fertilizer has been added many times.

2, implement the management of the branches and labors, reduce the inefficient consumption, and advocate the short-tail pruning on the pruning. There are no more than 10 female branches on each tree, and 2-4 buds are left on each mother branch. Thus, the second year When the buds sprout, the number of germination is small, the consumption of storage and nutrients is small, and the nutrients are concentrated to supply the result branches. When the summer shears, each main vine is fixed on the shelf, and the rest are not tied to the natural droop, which not only saves labor, but also inhibits the polar growth of the branches and improves the utilization of light energy. Because the branches are drooping, the branches and leaves block the ears, and also play a role in preventing sunburn.

3. Scientific management of ear

1 fixed spike. The large tree leaves about 10 ears per plant. When the ear is fixed, the excess inferior ear that is not well developed, and the secondary ear and some branching ears on each ear are removed.

2 use of growth regulators. 10-15 days before flowering, the flower ear can be elongated with the flowering inflorescence, and the fruit can be effectively increased by using Yiguoling 15-20 days after flowering.

3 All fruit bags are implemented. The use of high-quality large fruit bags, red earth grape branches and vertical cracks do not use old bags and newspaper bags to ensure that the fruit surface is clean and bright.

4. Prevention and control of pests and diseases, prevention and control

The prevention and control of pests and diseases is mainly based on prevention, mainly using protective agents, and rarely using therapeutic agents. In the prevention and treatment of leaf protection, we mainly use mancozeb and Bordeaux mixture, etc., and mainly use azoxystrobin in the protection of fruit and disease. After bagging the fruit, use an equal amount of Bordeaux mixture every 15-20 days to prevent downy mildew.
