Grapes, as one of China's traditional fruit trees, have sweet and nutritious fruits, deeply loved by consumers. Grape cutting is one of the important methods of grape propagation and is a commonly used breeding method by grape growers. Mastering the correct method of grape cutting can help increase the success rate of propagation and cultivate healthy and high-quality grape trees. This article will introduce you to the correct method of grape cutting.
Choose the Right Time for CuttingThe best time for grape cutting is usually in spring and autumn. Spring cutting can be done from March to April, and autumn cutting can be done from September to October, when the temperature is suitable for the rooting of grape cuttings.
Select Quality Cutting Material1. Choose healthy grape branches without diseases and pests as cutting materials.
2. The cutting material should be selected from mature branches, with a diameter of 0.5-1.0 cm.
3. Choose branches from the current year to ensure the rooting ability of the cuttings.
Handle Cutting Material1. Cutting: Cut the grape branches into segments 15-20 cm long, each retaining 2-3 buds.
2. Disinfection: Disinfect the cut branches with 75% alcohol or 0.1% potassium permanganate solution to prevent infection.
3. Peel: Before cutting, use a knife to cut the lower end of the branch into a wedge shape to facilitate rooting.
Prepare Cutting Substrate1. Choose a substrate with good breathability and water retention, such as river sand, perlite, etc.
2. The substrate needs to be disinfected to prevent the growth of germs.
3. Mix the substrate evenly, with the moisture content controlled at 60%-70%.
Cutting Operation1. Insert the processed grape branches into the substrate, with a depth of about 3-5 cm.
2. During insertion, keep the branches upright to avoid tilting.
3. The density of cutting should be about 50-70 plants per square meter.
Management Measures1. Watering: After cutting, water thoroughly to keep the substrate moist.
2. Shading: In the early stage of cutting, shade properly to reduce temperature and water evaporation.
3. Weeding: Regularly remove weeds to keep the cutting environment clean.
4. Fertilizing: About 15 days after cutting, apply a compound fertilizer of nitrogen, phosphorus, and potassium to promote rooting.
Management after Rooting1. After the grape branches take root, gradually increase the light time to promote plant growth.
2. Pay attention to the prevention and control of diseases and pests to ensure the healthy growth of the plants.
Mastering the correct method of grape cutting can help increase the success rate of propagation and cultivate healthy and high-quality grape trees. In the actual operation, strictly follow the above steps and adjust the management measures flexibly according to local climate and soil conditions. With your efforts, you will surely cultivate the ideal grape trees.
