Paper on pepper planting technology 1 pepper planting technology
[Abstract] Pepper is an indispensable condiment on people's table. In the new century, with the increasing market demand for peppers, pepper cultivation has become an important way for farmers to get rich. Pepper planting in Liaoning has a long history with excellent yield and quality. Based on the actual situation of pepper planting in Liaoning, this paper mainly analyzes the pepper planting technology, hoping to help improve the yield and quality of pepper.

Pepper is a favorite vegetable and condiment of China residents, and it is especially popular in some areas. Pepper is rich in various nutrients and has high medicinal value, among which the content of vitamin C is 4-7 times that of ordinary vegetables. Pepper, as a condiment, has the functions of stimulating appetite, invigorating spleen, stimulating appetite and helping digestion, and also has the important functions of dispelling cold and dampness, promoting blood circulation and removing blood stasis. In recent years, with the continuous adjustment of agricultural industrial structure, the planting area of pepper is on the rise, breaking the traditional planting mode, farmers have obtained higher economic income and greatly promoted the regional economic development.
1 Do a good job in seedling raising.
1. 1 seedling nutrient soil configuration.
The allocation of nutrient soil in nursery should be comprehensive, scientific and reasonable. Generally, one side of human and animal manure, 2.5 kg of calcium superphosphate, 0.5 kg of potassium sulfate and 0.5 kg of diammonium are needed, and then 1 bag of biological soil inoculant is added. After the nutrient soil is mixed evenly, it is wrapped with plastic film for closed fermentation, and then it is mixed with screened fine soil and fertilizer for use.
1.2 Soil preparation and sowing
Tidy up the ground in the shed, then spread a layer of 2-3cm thick plastic benzene board on the nursery ground, cut the two sides with soil to a height of 3-5cm, then spread a layer of plastic film on the board, evenly spread a layer of pebbles with a thickness of 2-3cm on the film, then spread a layer of straw, and finally evenly spread the prepared nutrient soil on the straw. Irrigation can start from the pebble bed, not directly into the border. After this work is completed, sow directly at the border, sowing 2-3 seeds per hole. After emergence, leave 1-2 seedlings, if more than 2 seedlings are left, pull out the weak seedlings and ensure 500 seedlings per square meter. After sowing, cover the seeds with a layer of soil 1 cm thick. The main cover should be gentle, not compact. Control the temperature of seedbed, with the temperature not lower than 12 degrees at night and not higher than 30 degrees during the day.
1.3 do a good job in seedling management.
Nutrition supply should be done well in pepper seedling stage. Drug control should be carried out three times throughout the seedling stage. First, when the seedlings grow to two leaves and one heart, the seedlings begin to differentiate into flower buds. At this time, the mixed solution of 1000 times of Tianda 2 1 16 Zhuangmiaoling +3800 times of Tianda 99% Zhan Mu Soder +3000 times of Tianda silicone+150 times of brown sugar should be selected to supplement the nutrition of seedlings and stimulate the vitality of seedlings. Spraying brown sugar mixture 800 times every half month, daily dosage 2 1 16 Zhuangmiaoling+1000 times daily dosage Yufeng +3000 times daily dosage silicone+150 times. Spraying 600 times of Qiangmiaoling +0 16 times of 75% chlorothalonil+3,000 times of silicone+150 times of brown sugar mixture before transplanting.
2. Do a good job of transplantation
2. 1 Make preparations before transplanting.
Be sure to do a good job of soil preparation and fertilization before transplanting. Before the land is thawed in the previous year, deeply cultivate the land for about 20-25cm, so that the land can collect rain and snow in winter to ensure the water content of transplanting in the next year. After the soil is thawed in spring, firstly, the human and animal manure is evenly spread on the soil surface, and then the rotary tiller is used for rotary tillage and ridging. Combined with soil preparation, fully decomposed chicken manure 1 m3, cow and horse manure1-3m3, 7.5kg of magnesium sulfate, 75kg of calcium superphosphate, 20kg of potassium sulfate and 8- 1 bag of soil inoculant are applied per mu, and then ridging is carried out, and a big ridge with a height of about/kloc-0 is made every other meter.
2.2 to do a good job of transplantation
Transplanting can be done in early May, and it will be done in early May. Before transplanting, it is forbidden to irrigate in greenhouse or open field 3-5 days before transplanting, so as to avoid lowering the ground temperature and not promoting the growth of root system. Before transplanting, if the soil moisture is poor, it can be irrigated one week in advance, and then covered with plastic film to raise the ground temperature, and seedlings will be raised in dry soil, so that seedlings will quickly absorb the water in the soil after transplanting in the open field, and the slow seedling period is short. During transplanting, the roots of seedlings must be coated with drought-resistant rooting agent. The main operation method is to dip the roots quickly after pulling out the seedlings, which can promote the root growth of the seedlings, take root quickly and delay the seedlings quickly. It has strong drought resistance and can resist external freezing injury.
2.3 Reasonable close planting
Pepper planting must be closely planted, one row and two rows, the row spacing should be kept at about 30 cm, the plant spacing should be kept at 25 cm, and about 5000 plants should be planted per mu. In the process of transplanting, the seedlings are transplanted into pre-dug planting holes, and then watered and covered with soil. When watering, the water temperature should be controlled at about 15 degrees, and each plant should be watered at about 200ml, so that the pepper seedlings can be delayed on the same day and the survival rate is high.
2.4 Scientific medication
In order to improve the resistance of seedlings after transplanting, it is necessary to spray 1000 times of Dayufeng (15g) +600 times of Dayufeng (2 1 16 Zhuangmiaoling (1 bag)+/kloc without rain. Spray 99% hymexazol 1 bag, or 75% chlorothalonil 20g, or 60% Baitai 1 0/5g, or 64% Dubangke 20g+ Tianda 21kloc-0/6 Tegua/kloc. If pests appear continuously, it is necessary to add 7 grams of 2% avermectin+15 grams of 25% diflubenzuron.
3 do a good job in the management of pepper in the later stage
Do a good job of supplementing fertilizer in the later stage. In the later stage, topdressing outside the roots can be used, and trace fertilizers such as 0. 1% urea and 0.2%-0.3% potassium dihydrogen phosphate can be used. When each red pepper grows to 60%-75%, harvest. When harvesting, pull up the whole plant, tie it into small bundles every 3-6 plants, and put it in the shade to dry. After all the peppers are dried, they are picked, stored, graded and sold.
