2. Spray 80% carbendazim 1500 times +10% imidacloprid 3000 times + high-efficient halothrin 1500 times to control Tenebrio molitori, Pyriacidae, Konzerthai, green-blind stink bug, black spot disease and so on.
3, spraying high-quality calcium fertilizer.
Six, flower bud physiological differentiation period (from late May to early June)
1, summer trim. Weed out excessively thin branches, competing branches, and saw branches.
2, prevention and treatment of fleas, pear hibiscus, green-blind staghorn, Cornell whitefly, black spot and so on. Spray 1.8% avermectin 5,000 times + 1500 times, and M-45 800 times.
3, foliar spray quality leaf fertilizer.
7. Fruit enlargement period (mid-June)
1, top-dressing watering. Mu topdressing pure nitrogen, phosphorus, potassium each 10 kg, timely watering after top dressing.
2. Prevent and control whitefly, mealworm, pear hibiscus, red and white spiders, and diseases. The agent can be used 3000 times 10% imidacloprid + M-45 800 times.
3, foliar spray quality leaf fertilizer.
Eight, fruit rapid expansion period (in late June - mid-July)
1. Control of Cornel mealybugs, yellow mealworms, red and white spiders, pear leaf rust, roundworm, black spot, etc. Available: 1500 times for Lethburn +15% for 哒螨 3000 times + 1000 times for Musteley.
2, foliar spray fertilizer. Spray amino acid liquid fertilizer or potassium dihydrogen phosphate 300 times.
3, timely watering when the weather is dry. The rain will drain in time.
Nine, fruit harvest period (July-August-August)
1, the fruit harvest. Batch harvesting in batches in time, strict grading, and ensuring quality.
2, foliar spray potassium dihydrogen phosphate 300 times.
3, control Tenebrio, Cornell mealybugs and so on. It is possible to use 1500 times more efficient hydropermethrin and 1000 times more carbendazim.
4. After the fruit is harvested, apply base fertilizer and water. Timely prevention of pests and diseases. Mushi fermented organic fertilizer 5000 kilograms, and add 20 kg of pure nitrogen, phosphorus, potassium, timely watering. Foliar spraying urea 300 times 1-2 times.
Ten, nutrient accumulation period, dormant period (September-October end) Prevention of pests and diseases, can be used Sulphur Suspension 300 times + 1000 times. Clear the dead branches, fallen leaves, diseased fruits, and weeds in the park.
