Protected production of spicy (sweet) peppers, improved temperature conditions, and can adjust soil and air humidity, effectively avoiding the dangers of high temperature and high humidity, drought and flood. Through reasonable fertilization, artificially create the best environmental conditions for the growth of pepper, and prolong the result period, and obtain stable yield and high yield.
1. Cultivate strong seedlings Pepper and sweet pepper sowing and planting period, depending on the conditions of the protected area facilities. The breeding method and place of spicy (sweet) pepper are almost the same as those of tomato. The germination of peppers has strict requirements on water and bed soil. The bed soil is well ventilated, suitable for temperature and humidity, and rich in nutrients, which is a prerequisite for cultivating strong seedlings. Therefore, nutrient soil needs to be configured to meet the growth and development of seedlings.
Bed soil allocation method: 30% decomposed horse manure, 20% decomposed manure, 50% garden soil without seedlings, and 50g of diammonium phosphate per cubic meter of soil, evenly sieved, leveled畦, watering, sowing and covering the mulch.
When the seedlings have two leaves and one heart, the seedlings should be divided in time, and the nutrient soil method should be arranged before the seedlings to be the same as the seedbed soil. After the seedlings are warmed, the light is added and moisturized, which is very important for cultivating strong seedlings.
The standard of strong seedlings for rapid seedling cultivation of pepper: the seedling age of winter-spring or spring-cultivated pepper is 80~110d. From the physiological seedling age, the seedling height is 18~20cm, 9~13 true leaves, the leaves are dark green, the leaves are large and thick, the stems are thick and the stems are 0.6cm thick, and the big buds are not flowering. The root system is developed, with many roots and no disease.
2. Re-applying the base fertilizer pepper has strong adaptability to soil, sand, loam, clay loam, etc. can grow and develop, but the loam or humus soil with deep soil, loose and fertile soil, rich in organic matter, good permeability and permeability Suitably, a soil pH of 6.8 is most suitable.
Sweet peppers have similar environmental requirements to peppers but are less resistant to peppers.
Spicy (sweet) peppers are most difficult to smash. Before planting, they should first be disinfected in the shed and fertilized to prepare the land. The sorghum is sun-dried in time after the harvest. Combined with cultivated land, 667m2 is cooked to 30~40kg, evenly spread, 25~30cm deep, for squatting or ridge. It is advisable to choose a sunny day with a relatively high temperature and ditch the plant.
3. Skillful application of topdressing Controlling the temperature, humidity and nutrient ratio is the key to the management of peppers after planting. Peppers are warm, hi-fer, and hi-water, while at the same time resisting high temperatures, not being able to withstand fat and avoiding wetness. Pepper has a long growth period and is harvested several times. It must be ensured that there is sufficient nutrient supply during the growth period. In addition to the application of the base fertilizer, it is also necessary to pay attention to the top dressing. According to the growth law of the pepper and the characteristics of the fertilizer, the principle of diligent application should be adopted.
The first top dressing can be carried out 15 days after planting, in order to promote the early growth of the seedlings, the 667m2 of the water is applied with 10kg of urea or 750~1000kg of rare human waste. For the second time, when the pepper is swollen, 667m2 is applied with ammonium sulfate 15~25kg. For the third time in the peak period, another 667m2 of 20~25kg compound fertilizer or 40kg of decomposed bean cake. In the future, according to the growth of the plant and the soil fertilization status, the fertilizer should be chased once every 4 waters, and the compound fertilizer of 20 to 30 kg is generally applied at 667 m2, which can prolong the result period and prevent early decay.
In the early stage, the plants are still small, and it is necessary to pay attention to the application of chemical fertilizers about 10 cm away from the plants to prevent burning of the plants. When it is sealed in the later stage, it can be applied with water and fertilized with water.
In order to promote the development of the root system of pepper, combined with watering and topdressing, the soil should be cultivated in due course. In order to prolong the results period, combined with pruning, updating the results, reducing the results, timely watering and topdressing, and promoting new branches, can increase the fruit set rate and increase the yield at the peak of the second result.
