How to Plant Grapes for Good Profit
Grapes are a very common fruit in our daily lives, loved by many and cultivated by many. Of course, grape farmers hope to see profits every year, which is not impossible. If the following points are done promptly after the grape harvest, the profits for the next year are usually good.
Cleaning the Orchard
1. Cut off the diseased and dead branches, remove the diseased branches, fruits, and eggs, and burn or transport them out of the orchard for treatment.
2. Peel off the bark of old trees to eliminate the source of diseases and pests.
3. Spray a mixture of 5-degree lime sulfur and 0.2% to 0.3% laundry detergent on the branches, ground, cement pillars, and frames.
4. Deeply turn the entire orchard, burying the remaining branches, leaves, and fruits into the soil, which can kill some overwintering pathogens.
5. Clearing the weeds along the roadsides has a good effect on killing overwintering pests.
Strengthening Fertilization and Water Management
1. After grape harvesting, apply a high-nitrogen and high-potassium fast-acting fertilizer promptly, commonly known as "Ring Sun Fertilizer." Generally, apply 7.5-10 kg of urea and 5-7.5 kg of potassium fertilizer per mu.
2. For grape orchards with weak growth and poor soil fertility, apply 5%-10% of animal manure 2-3 times. At the same time, the base fertilizer should be applied in autumn promptly. The base fertilizer should be applied by October 20. Apply 500-1000 kg of biochar (or commercially available bio-organic fertilizer) per mu, or 2-3 tons of decomposed farm manure (such as cow dung, sheep dung, etc.), plus 30-40 kg of compound fertilizer.
Strengthening Branch Management
1. After grape harvesting, deal with secondary branches promptly. Generally, leave one primary secondary branch at the top of the main branch, 5-7 leaves at the top of the secondary branch, and 2-3 leaves at the top of the secondary branch.
2. For grape orchards with small spacing, high density, and poor maturity, quickly cut off 30%-50% of the smaller and less mature branches.
3. Strictly control the autumn lateral branches, such as "Red Earth," "Sunshine Rose," "Black Brad" and other easy-to-grow varieties and grape orchards. Use 98% liquid concentrate at 500-750 times, mixed with 21% Hefeng Boron 3000 times, spray 40-50 kg of liquid per mu, spray on the top of new shoots, every 15-20 days, spray 2-3 times.
Strengthening Pest and Disease Control
The main diseases after grape harvesting include downy mildew, black spot, brown spot, and powdery mildew, mainly affecting leaves. The main pests include cotton bollworm and oblique striped caterpillar moth.
1. To prevent and control downy mildew and black spot after harvesting, generally use 50% dimethomorph 2000 times, 40% flusilazole 8000 times, 5.7% abamectin 3000 times, and full-nutrition foliar fertilizer.
2. When controlling foliar diseases and pests is good, spray with a multi-dose Bordeaux mixture carefully, 250-300 kg of liquid per mu, every 15-20 days, spray 2-3 times.
Removing Rain Protection Film in Time
Grapes in Hunan are mainly planted in areas protected from rain. The light transmission rate of the遮光膜 is generally around 80%, and around 50% in the later stage. Moreover, Hunan has insufficient sunlight. Therefore, the rain protection film should be removed promptly after harvesting. Practice has shown that removing the rain protection film in time after grape harvesting increases the number of flower heads in the orchard by more than 30% compared to orchards where the film is not removed.
Okay, that's what I wanted to share with you today. To grow grapes profitably next year, it is necessary to promptly do the above few things.
