How to manage newly planted grape seedlings
Grapes are a common fruit with a pleasant taste, and they are becoming more expensive in the market. Now, many farmers can grow grapes in their fields. How do we manage the newly planted grape seedlings? Next, I'll teach you!
Tree Management
No matter when planted, in spring, summer, or autumn, when the tender branches grow to about 10 centimeters, select only one strong branch per plant, and eliminate the excess tender branches by pressing them against the root. When the seedlings grow to about 20 centimeters, they must be tied to the first wire on the ground with a tie-down to ensure they grow upright and avoid being blown down by the wind. When the seedlings reach 1.2 meters in height, the vigorous plants will be pinched off. Before and after pinching, remove the secondary branches growing below 50 centimeters from the ground on the main vine. The remaining secondary branches should be pinched repeatedly with 1-2 leaves. The extending branch at the top of the main stem can be pinched twice, with a length of 0.3-0.5 meters, and all secondary branches can be pinched repeatedly with 1-2 leaves; later, ineffective growth and consumption are transformed into effective accumulation, which thickens the main stem, increases the degree of lignification, expands the root system, and lays a solid foundation for safe overwintering and vigorous growth in the second year.
Fertilization and Water Management
1. To promote vigorous growth of the plants and early formation, early fertilization should focus on nitrogen fertilizer, supplemented by organic fertilizer. Starting from June 1st, depending on the weather conditions, water the plants under the film every 10-12 days, without leaving any empty water, using dung or water-soluble fertilizers and urea fermented in a septic tank. Spray a urea solution on the leaves every 15 days. Initially, the fertilizer concentration should be low, and as the plants and roots grow, the fertilizer concentration and amount of water can be gradually increased.
2. In the later growth stage, that is, after the end of July, to accumulate high nutrients in the plants, increase the root system, make the main vines plump, and improve the lignification of the branches, it is necessary to control growth. At this stage, it is recommended to supplement nitrogen fertilizer, apply an appropriate amount of phosphorus and potassium fertilizer at the roots, spray phosphorus and potassium on the leaves every 10-15 days, and reduce the frequency and amount of watering, or even stop watering.
Autumn Pruning
1. To minimize ineffective growth and consumption, autumn pruning or pruning of the seedlings planted in the same year should be done promptly, which means removing all tender branches and small leaves (secondary branches more than twice and leaves less than half the size of normal leaves), leaving only the thick branches and large leaves.
2. When harvesting in winter, the main vines over 1 meter high should be cut where the branches are mature and the cut thickness is 1 centimeter; for main vines about 1 meter high, they should be cut at the mature part, with a cut thickness of 0.8 centimeters; and for main vines below 0.5 meters high, they should be pruned 3-5 full eyes above the ground. After the main branches are cut, all secondary branches are cut.
