How to achieve high yield of pepper? Introduction of high-yield fertilization technology for pepper
Pepper is a vegetable that people can't live without in daily life. Pepper cultivation covers all provinces and regions in the country. Many farmers will encounter many problems when planting peppers. But the most concern for farmers is the problem of pepper production. So how do you make chili? Can you produce high yields? You can't miss the high-yield fertilization technology of peppers! Fertilizer characteristics during the growth period of pepper: 1. Pepper is a vegetable with a large amount of fertilizer. For every 1000 kg produced, about 5.2 kg of nitrogen, 1.2 kg of phosphorus pentoxide, and 6.5 kg of potassium oxide are required. 2. The result from the initial flowering to the full bloom is the period of vegetative growth and reproductive growth of pepper, and it is also the period of absorbing most nitrogen, accounting for 34% of the total absorption; from flower to maturity, the demand for phosphorus and potassium is the most. , accounting for about 50% of the total absorption. Nitrogen fertilizer demand law: 1. 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. 2. Excessive application of nitrogen, excessive growth of nutrients, fruit will produce umbilical rot due to the inability to obtain calcium supply in time. 3, during the initial flowering period to control nitrogen fertilizer, otherwise, the plant is long, reproductive growth is postponed. The role of phosphorus and potassium: 1. Insufficient phosphorus can cause falling buds and falling flowers. Phosphorus is an important factor in the development of flower buds. 2. 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. Lack of trace elements: Capsicum has certain demand for trace elements such as calcium, magnesium, boron, zinc, etc., and pay attention to supplement during flowering. Prevention and control of pepper "three falling": 1. High temperature, rainy season, easy to fall, fall flowers, drop fruit. 2, to control the application of nitrogen fertilizer, small water and water, drought and temperature, and timely removal of rain. 3. Spray 300 times of borax solution during the Sheng Lei period to increase the fruit setting rate. 4. Spray 30ppm of the spirit and 1time of 150ppm of the anti-falling substance once before the arrival of the rainy season, and spray the potassium dihydrogen phosphate or zinc sulfate in combination. 5. Spray carbendazim or thiophanate (methylthiophanate) 800-1000 times solution. Re-application of base fertilizer: It produces 5,000 kilograms of chili per mu, 5000-8000 kilograms of cooked organic fertilizer, and 40-50 kilograms of potassium sulfate-type compound fertilizer (3*15). Apply 60% base fertilizer before the preparation of the ground, and apply 40% of the ditch when planting. Stabilize plant fertilizer and slow seedling fertilizer: 1. Apply 5 kg of urea as a fixed fertilizer before the planting. 2. After the pepper is slowed down, if the leaves are yellow, the seedlings are slow or not seedling, 5 kg of urea can be applied to the mu to promote the growth of the seedlings; if the seedlings are strong, they can not be fertilized. Always apply root fertilizer: 1. After the pepper is slowed down, spray 0.3% potassium dihydrogen phosphate and 0.6% urea solution every 10-14 days. 2. From the beginning of the break, add 0.2% zinc sulfate and 0.2% ferrous sulfate mixture to spray 1-2 times. 3. At the beginning of the flowering period, 0.2% borax or 0.1% boric acid solution is added twice. 4, full flower period, add 0.2% calcium nitrate 2-3 times. The introduction of high-yield fertilization technology for peppers has been completed, and it is a more comprehensive understanding of the cultivation of peppers. In fact, Xiao Bian wants to remind the farmers that whether it is planting vegetables or fruit trees, fertilizer is essential, and it is also a key factor in whether or not planting is high-yield, so be sure to pay attention to it!
