How does pepper planting achieve high yields? Key points of high quality and high yield cultivation techniques of pepper
The theme of this article about pepper planting technology brought to you by Huinong.com is the summary of pepper planting technology and drug use. Therefore, there is a need for vegetable farmers to take reference. This article not only talks about pepper planting technology, but also talks about it. The prevention and treatment of common diseases of pepper.
First, field management
Drought resistance
Pepper is afraid of drought and is afraid of it! (Arid is easy to induce poisonous diseases, when the water is flooded for several hours, the plants will die and die)
When you water the water, you should pay attention to it.
At first glance, if you see that the pepper leaves are not severely wilted at noon, it means that the soil is not dry, and there is no need to water; if it is severely wilting, you should pay attention to it when watering. First, watering the weather. (Note: Before the rain Can not water), the second is to water the small water to prevent water from falling and causing the leaves to fall.
In the field, water should be drained in time to ensure that there is sufficient water and no harmful effects.
Cultivating weeding
In the post-rain, after watering or when the soil is found to be knotted, it is necessary to timely cultivate the loose soil, which can promote the development of the root system of the pepper and improve the nutrient absorption capacity.
Note: After the cultivating, the ground should be leveled to prevent the water from being blown away by the wind and lose the humidity of the pepper growth.
Second, fertilization management
Use foliar fertilizer
During the fruit setting period, 0.3% to 0.4% potassium dihydrogen phosphate solution can be sprayed and sprayed once every 7 days. When combined with pest control, it can effectively prevent falling flowers and fruits and reduce pests and diseases.
Note: Calcium deficiency in the acidic soil solution in the southern region can be appropriately sprayed with calcium foliar fertilizer to prevent and control umbilical rot caused by calcium deficiency.
Early onset of umbilical rot caused by calcium deficiency
In the absence of magnesium, use 0.5% to 1% magnesium nitrate solution, spray once every 5 to 7 days, and spray 3 to 5 times.
Capsicum magnesium deficiency symptoms
Timely topdressing
Time: Evening
Location: 15 cm from the root
Principle: a small number of times
The first top dressing: after most of the peppers are placed in the fruit, when the second water is poured, the key fertilizer is combined with the key
Top dressing after the first time: After each fruit harvest, combine with watering and topdressing once.
Fertilizer type: high nitrogen and high potassium fertilizer (such as urea, potassium sulfate)
Note: When pepper is used as fresh pepper, the top dressing should be applied with nitrogen fertilizer, but it should not be excessive. When pepper is used as dried pepper, after the fruit is red, the nitrogen fertilizer and potassium fertilizer are added.
Third, disease prevention and control
Easy to occur during picking
Viral diseases, epidemics, anthracnose, gray mold, scab, blight, soft rot, black spot, cotton rot. Tobacco budworm, aphid, whitefly, and leafy fly (ghost character).
Reminder:
Do a good job in the management of pepper picking, pay attention to watering and fertilization, can improve the output, ensure the quality of the effect, greatly improve your income!
