1. Cultivation Management:
-
During the entire budding and shooting period of the grapevine, timely and thorough cultivation and loosening of the soil should be carried out in the vineyard. The depth of cultivation should be 15-20 centimeters, promoting the growth of grapevine roots. Strengthen soil cultivation for plants with weak root systems.
2. Weed Control:
-
In vineyards with heavy weed growth, weed control should be prioritized to reduce nutrient consumption. Weeding should be done manually, with the best results achieved during weed emergence and before seeding. Herbicides such as 41% glyphosate isopropylamine salt or 30% glyphosate can be used at a concentration of 80-120 grams per 30 kilograms of water, effectively targeting young weeds.
3. Fertilization:
-
Grapevines require a large amount of nutrients during budding and flowering, so timely fertilization is essential. Apply compound fertilizer (15-15-15) at a rate of 20-30 kilograms per mu, along with approximately 30 kilograms of phosphate fertilizer (adjust the amount according to the region and tree vigor), promoting growth and flowering. Foliar application or balanced water-soluble fertilizer is more effective during this period.
4. Shoot Thinning:
-
Shoot thinning should be carried out to approximately 50% after leaf unfolding, around 20 days later when the new shoots reach 10 to 20 centimeters in length.
5. Mulching:
-
Covering the ground under or slightly away from the grape rows with mulch and straw helps retain moisture, improve soil, and enhance the growth environment for the roots of grapevines.
In May, the beginning of summer brings hotter weather and increased chances of thunderstorms in some areas. Therefore, pest and disease control becomes even more crucial in hot and humid conditions.
