Wanting to Improve Grape Benefits for the Next Year
Main content introduction: Let's explore the topic of improving grape benefits for the next year related to flower cultivation. Here's what you need to know.
Wanting to Improve Grape Benefits for the Next Year
Grapes are a very common fruit in our daily lives, loved by many and cultivated by many. Of course, grape farmers hope to achieve benefits every year, which is not impossible. If the following points are done promptly after grape harvest, the benefits for the next year will usually be good.
Cleaning the Garden
1. Cut off the diseased and withered branches, remove the diseased branches, fruits, and eggs, and burn or transport them out of the garden for treatment.
2. Peel off the bark of old trees to eliminate the root causes 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 framework surfaces.
4. Deeply till the entire garden, turning the remaining branches and fruits into the soil, which can kill some overwintering pathogens.
5. Removing roadside weeds can effectively kill overwintering pests.
Strengthening Fertilization and Water Management
1. After harvesting grapes, apply a high-nitrogen and high-potassium fast-acting fertilizer, commonly known as "circular sun fertilizer." Generally, apply 7.5-10 kg of urea and 5-7.5 kg of potassium fertilizer per mu.
2. For grape gardens with weak growth and poor soil, apply 5%-10% of animal manure 2-3 times. Also, the base fertilizer should be applied in autumn in a timely manner. The base fertilizer should be applied by October 20. For each mu, apply 500-1000 kg of biochar (or commercially available bio-organic fertilizer), 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 harvesting grapes, promptly deal with secondary branches. 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 gardens with small spacing, high density, and poor maturity, quickly cut off 30%-50% of the smaller, poorly matured branches.
3. Strictly control autumn lateral branches, such as "Red Earth," "Sunshine Rose," "Black布拉德" varieties and grape gardens. Use 98% liquid concentrate 500-750 times, add 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 Disease and Pest Control
The main diseases after grapevines face after harvest include downy mildew, black spot, brown spot, and powdery mildew, mainly affecting leaves. The main pests are cotton bollworms and oblique-striped nocturnal moths.
1. To prevent downy mildew and black spot after harvest, generally use 50% dimethomorph 2000 times, 40% flusilazole 8000 times, 5.7% abamectin 3000 times, and full-nutrition foliar fertilizer.
2. When foliar disease and pest control is good, spray carefully with multiple doses of Bordeaux mixture every day, spray 250-300 kg of liquid per mu, every 15-20 days, spray 2-3 times.
Timely Removal of Rain Protection Film
Grapes in Hunan are mainly planted in areas protected from rain. The light transmission rate of the shading film is generally around 80%, and about 50% in the later stage. Additionally, Hunan has insufficient sunlight. Therefore, the rain protection film should be removed promptly after harvest. Practice has shown that in grape gardens where the rain protection film is removed promptly after harvest, the number of flower heads increases by more than 30% compared to gardens where the film is not removed.
Alright, that's what I wanted to share with you today. To grow grapes with good benefits next year, you also need to do the above things promptly.
