Although grape diseases and insect pests do not pose a hazard in March, they have also intensified breeding activities before the sprouting of the grapes and are ready for initial infestation at the time of germination. Therefore, in March, the following management is mainly carried out: When tying vines on top, the first thing to do is to make the vines evenly distributed on the surface of the rack. Keep the distance between the vines roughly equal, generally 20 to 25 centimeters on the same side. To avoid crossing, overlapping, dense crowding. When binding, pay attention to leave room for the growth of the branches, but also firmly attached to the frame, using a cross-shaped tie. Tied ropes are best made of materials that are not easily damaged by the tree, such as cloth, rice straw, hemp rope, or corn bran. After the clean garden disinfection and tying of the vines is completed, the old rough skin on the rough branches of the grapes shall be promptly scraped clean, together with the weeds, dead branches, dry leaves, and the debris of the new shoots left on the iron wire. , All cleared out of the park, burned or buried. When the grape winter buds are sprouting, the whole garden will be sprayed with drugs to completely clean the garden. The pharmaceutical selection gold helmet 52.5% chlorpyrifos cypermethrin EC 800 times + dazzling tornado 25% diflubenzuron WP 2000 times + top-good 10% Difenoconazole Or 70% RenoRTO 1000-fold mixture. You can also use 3 to 5 Baume degrees lime sulfur to eradicate the winter pathogens and pests in the vineyard. The spraying should be thorough and thorough, and the trees, floors, columns, and wire must be sprayed. Normally, the organic fertilizers such as soil miscellaneous fertilizers, circulatory fertilizers and chicken manure are mainly applied per acre, and a small amount of nitrogenous fertilizers is added. Mature fruit trees are usually applied with 50 to 100 kg of organic fertilizer plus 0.5 kg of urea, or 15 kg of diammonium phosphate. After the soil is loose, cultivating the orchard again, the cultivating depth of 5 to 10 centimeters is appropriate, after the cultivator is flat. Under the tree, it is better to cover the black mulch under the trees if conditions are suitable for warming and protecting the grapes. There are many advantages of the film coating. First, it can increase soil temperature, promote root growth, absorb more nutrients, and favor flowering results. Second, it can reduce soil surface water evaporation in the summer dry season, keep the soil moist, and help fruit development and expansion; Can inhibit the growth of weeds, reduce nutrient consumption, reduce the humidity in the park, reduce the occurrence of pests and diseases. The tree tray should be trimmed before coating, paying attention to the low height outside. When the film is covered, it must be compacted with earth pressure.

Before fertilizing and watering the sprouts, after the cultivating and cultivating the gardens, when the grape buds begin to enlarge, the scales are broken, and when the hairs are exposed, a fertilizer should be applied and irrigation should be performed immediately after fertilization. The purpose is to ensure the normal germination of bud eyes and the growth of new shoots.
