How to plant colorful pepper planting techniques and matters needing attention

Colorful pepper is a variety introduced and cultivated from abroad in our country. At present, it is distributed in many places in our country, and it is a kind of common plant. Colorful peppers are rich in colors, such as purple, red, yellow, green and so on, which are highly ornamental and edible, so they attract a lot of people to plant. Before planting, let's take a look at its planting technology.

How to grow colorful peppers

On the basis of planting as shallowly as possible, on the basis of planting as shallowly as possible, the root system of colorful pepper is washed higher than the ground and the unearthed part of the root system is exposed. Do not plant deeply when transplanting as shallowly as possible. if you raise seedlings with a nutrition bowl, when planting, you should expose the bowl body to the ground.

Planting techniques of colorful Pepper

1. Sowing and raising seedlings. Spring planting uses plastic film to raise seedlings in the middle and last ten days of March, which requires the ground temperature to be stable above 10 degrees. Summer seedlings are raised from late April to early May. Soak the seeds in warm water before sowing to promote germination, sow on demand when the white bud tip is exposed, sow 3 grains in the hole, and cover with 2 cm thick moist soil. The nursery bed should be selected in the leeward direction, the bed width is 1 meter, and the bed surface is covered with 20 cm thick fertile fine soil, leveling the bed surface, filling enough water to infiltrate into the soil layer, sowing buds and covering a layer of fine sand at the same time. Finally, spread a layer of plant ash evenly and build an arch shed with bamboo bracket. the arch shed is 25 cm above the ground and sealed with plastic film. when the seedlings grow to 3 true leaves, uncover the film and ventilate according to the weather conditions to prevent the seedlings from being injured by strong light, and at the same time, the distance between the seedlings should be 4 cm. In addition, Kangkuning or chlorothalonil should be added at the same time 0.5% potassium dihydrogen phosphate at the seedling stage and sprayed evenly for 3 times to prevent early defoliation.

2. Ground preparation and transfer. When the seedling grows to 5 true leaves, it can be transferred. The field must apply sufficient base fertilizer and apply 1500 kg of animal manure, 25 kg of phosphate fertilizer, 10 kg of urea or 40 kg of ammonium bicarbonate every 667m2. Large and small seedlings should be transferred separately, narrow row 40 cm, wide row 60 cm, plant distance 35 cm, thin ground late-loaded colorful pepper plant distance 25 cm.

Matters needing attention in planting colorful Pepper

After load transfer, it should be moisturized with enough water, 15 kg of urea should be used for every 667 square meters at the beginning of flowering, and fruit-protecting fertilizer should be applied again in July to ensure that there is no premature senility in October. The plant should be combined with weeding, loosening the soil and cultivating the root before sealing the ridge, so as not to hurt the root deeply. Watering during high temperature and drought, dig ditches in the field. Prevent stagnant water from falling leaves, flowers and fruits. In order to prevent the harm of disease, broad-spectrum fungicides such as benzen zinc and carbendazim can be used in combination with insecticide. at the same time, plant activin and high yield can be evenly sprayed on the opposite side of leaves.

Diseases and insect pests of colorful pepper and their control

1. Whitefly. Whitefly is currently one of the most difficult pests to control. Now yellow board trapping and chemical control are commonly used. When the whitefly is serious, it can be irrigated with 3000 times Amelo. The effect can be maintained for about 2 months after root irrigation. Can also be used once net, deltamethrin, cypermethrin and other agents.

2. Epidemic disease. Control method: soak the seeds with 1000 times metalaxyl solution for 2 hours, then raise seedlings with disease-free new soil to prevent the seeds from carrying bacteria. Use high border planting to avoid stagnant water and pay attention to control the amount of water and times of watering. After planting, the roots were drenched and the plants were sprayed with copper oxychloride 1000 times. After the onset of the disease, it was sprayed with prednisolone, Luke Xing, Kesha and Trichoderma, and the control effect was better.

3. Anthrax. Prevention and control methods: timely drainage after rain to avoid stagnant water. Choose a more ventilated place to plant. Spraying 800 times of 70% methyl topiramate wettable powder or 600 times of 75% chlorothalonil wettable powder or 800 times copper oxychloride at the initial stage of the disease.

When planting colorful peppers, we must do a good job in site selection, and then sow seeds at the right time. After planting, we must do a good job in field management, to ensure its fertilizer and water, so that it can grow well. Colorful pepper is also vulnerable to diseases and insect pests, so pest control work should also be done in place.
