What fertilizer is good for pepper? High-yield fertilization technology for pepper
Pepper is a very common vegetable. Its consumption rate in our daily life is very high, and the proper consumption of some peppers has certain benefits to the human body. At present, it is planted in many places in China. However, when planting peppers, many people do not know what kind of fertilizer should be chosen, how to increase its fruit setting rate.
Nutritional characteristics of pepper growth
The pepper continuously absorbs nitrogen fertilizer from the early stage of growth to the harvesting stage, and there is a direct relationship between the yield and the amount of nitrogen absorbed. The spicy taste of pepper is related to the amount of nitrogen fertilizer, and the application amount will reduce the spicy taste. For dried chili, the nitrogen fertilizer should be properly controlled to increase the proportion of phosphorus and potassium fertilizer. If the amount of nitrogen fertilizer is too much, the vegetative growth is too strong, and the fruit will produce umbilical rot due to the inability to obtain calcium supply in time. In the early flowering period, it is necessary to control the nitrogen fertilizer. Otherwise, the plants are long and the reproductive growth is delayed.
As the plants continue to grow, the amount of phosphorus absorbed increases. However, the amount of change in absorption is very narrow, and the total absorption is about 1/5 of that of nitrogen. Insufficient phosphorus can cause falling buds and falling flowers. Phosphorus is an important factor in the development of flower buds.
Potassium is less absorbed in the early growth stage of pepper, and it increases after picking fruit. In the result period, if the soil potassium is insufficient, the leaves will show potassium deficiency, defoliation occurs, the fruit setting rate is low, and the yield is not high.
How can pepper be fertilized to produce high yield?
The amount of calcium absorbed is lower than that of tomato, and if it is insufficient, the umbilical rot of the fruit has been induced. Calcium is indispensable throughout the growth period.
At the initial stage of planting, the absorption of magnesium is less, and the absorption amount increases during the harvesting period. At this time, if magnesium is insufficient, the veins become yellow and become magnesium deficiency, which affects plant growth and fruiting.
When the pepper is deficient in boron, the color of the leaves is yellow, the growth of the heart leaves is slow, the xylem of the roots becomes black and rot, the growth of the roots is poor, the flowering period is delayed, and the flowers are unrealistic, which affects the yield.
Regardless of the time of the pepper, proper use of fertilizer is important. It is necessary to apply scientific fertilization. It is important to fertilize at what time and what kind of fertilizer you like. Especially during the period of reproductive growth and vegetative growth, you should not use it to avoid unnecessary trouble.
High-yield fertilization technology for pepper
Capsicum fertilization technology
1. Base fertilizer: 5,000 kilograms of chili per mu, 5000-8000 kilograms of organic fertilizer (pig manure, human waste, soil fertilizer, etc.), 25-50 kg of superphosphate and organic fertilizer, mixed with potassium sulfate 25 -30 kg. Apply 60% base fertilizer before the preparation of the ground, and apply 40% of the ditch when planting.
2, seedling: In the 11.3 square meter seedbed, apply 150-200 kilograms of organic fertilizer, apply 1-2 kilograms of superphosphate, and plow 3-4 times.
3, the dung water stable seedlings planted: Capsicum fruit above stems and leaves grow 3-4 knots, combined with watering to trace the perishable manure urine 2000 kg per mu. After half a month, the second amount is applied as before. Apply 1500-2000 kg of organic fertilizer or 40 kg of ammonium sulfate per mu.
4, foliar topdressing: pepper flowering results, can also spray 0.5% urea plus 0.3% potassium dihydrogen phosphate.
How to make peppers more fruit
1, temperature management. At this stage, the weather changes relatively large, from the high temperature of the previous period to the current ten-degree drop, the temperature drop is particularly fast. At this stage, one is to pay attention to the temperature, the key is to pay attention to the temperature difference. The pepper is in the fruit setting period, and the temperature to be mastered during the day is between 26-30 degrees and between 13-15 degrees at night. Because the pepper is in the fruit setting period, it is sensitive to the temperature requirements. We should adjust it according to the appropriate temperature of the pepper fruit setting period.
2. Water management. At this stage, it is necessary to properly control the water during the fruit setting period. According to the soil in the shed, the ground is already arid, and it needs a small water to be poured in the morning. After pouring the water, it is necessary to control the water, and then wait for the fruit to sit and then water. Now the soil dryness and humidity are OK, the greenhouse can control the water, and then wait for the fruit to sit and then water the fruit.
3. Promote differentiation. At this stage, it is in the fruit setting period. It is necessary to differentiate the flower buds and make the flower buds full.
How to water the pepper
1. First, during the flowering of the pepper seedlings, the watering should be properly controlled to avoid the occurrence of prosperous conditions and promote fruit setting. For most plants, after the fruit is set, the seedlings are finished, and the second watering is carried out to carry out the fertilization. The demand for fertilization is to use urea or human excrement, ditching and applying darkness, and then applying watering to the seedlings after fertilization.
2. Secondly, after picking the pepper, water it again. After the pepper enters the fruiting period, it should be watered for a week or so. Because it is easy to evaporate at this time, the seedlings must be kept moist with the watering method.
Common pests and control of pepper
1. Aphids. Remove weeds in and around the field and reduce the source of plutonium. It is best to eliminate aphids in the initial stage, which can be sprayed with 10% imidacloprid 1000 times solution or 1% barium 2000 times solution.
2, sassafras. Eliminate weeds and litter in the field and around it in time to reduce the source of insects. When the pest is found, it should be used in time. You can choose 15% broom WP 2000 times solution, 40% lycopene 1000 times solution, 75% gram emulsion 1500 times solution. The back of the young leaves and the tender stems of the upper part of the main spraying plant were sprayed once every 10 days, and sprayed continuously for 3 times.
There are also a lot of fertilizers that should be used for peppers. The fertilizers and fertilization techniques chosen at different times are different. If you want to make the peppers more fruity, you must do a good job in temperature and moisture management. Only by doing this can we ensure that the growth of peppers is better.
