How to grow green pepper

Green pepper is a kind of vegetable that likes temperature and is not tolerant to stagnant water. Because of its high nutritional value and wide consumption rate, it is more and more favored by consumers, and the price of green pepper in some places is getting longer and longer. So many people want to plant green pepper, about its planting method, there are a lot of skills.

How to grow green pepper

1. Raising seedlings. Generally, seedlings will be raised in advance before planting, and this time should be about 1 to 2 months in advance. For the treatment of green pepper seeds when raising seedlings, we can choose chemical soaking or conventional warm soup soaking. There are no advantages and disadvantages between these two methods. The main purpose of seed soaking is to control common pepper anthracnose, virus and bacterial spot, while warm soup is to sterilize to prevent the occurrence of scab and Sclerotinia sclerotiorum.

2. Sowing and interplanting. The bed soil when growing green peppers is preferably soil that has not grown eggplant fruits and vegetables for three years. The bed soil should be screened and lO kg of high quality organic fertilizer should be applied to every square meter of seedling bed. The seedling bed is 10 cm high and should be leveled. Pour enough bottom water before sowing. After the water is completely seeped, cover a layer of fine soil, spread the germinated seeds evenly on it, cover the soil 5 mm after sowing, cover the plastic film and buckle the small arch shed in time, in order to increase temperature and moisturize, promote early emergence of seedlings. When the cotyledons of the young seedlings are flattened, the seedlings that are overcrowded, diseased, malformed and poorly grown should be pulled out, and then covered with soil to protect the roots.

3.Seedling and transplanting. When the green pepper seedlings grow to 4-5 true leaves, they should be divided and transplanted. They can be transplanted according to the hole distance of 7 to 7 centimeters, and about 2 plants can be placed in each hole, and then fill in the fine soil of the seedling bed on the cover.

Living conditions of Green Pepper

1. Temperature. The suitable temperature range is 15-35 ℃, the suitable temperature range is 25-28 ℃, and the germination temperature is 28-30 ℃. Like to be moist, afraid of drought and waterlogging, require the soil to be moist without stagnant water.

2. Light. The light requirement is not strict, the light intensity is medium, and the light intensity is 10 to 12 hours a day, which is beneficial to blossom and bear fruit. The growth and development of green pepper needs adequate nutritional conditions. For every 1000 kg of green pepper, 2 kg of nitrogen, 1 kg of phosphorus, 1.45kg of potassium and appropriate amount of calcium fertilizer are needed.

3. Soil. For the requirements of the soil, the wet sandy loam is better, the soil pH should be neutral, and the soil can also be slightly acidic.

Fertilizer and Water Technology of Green Pepper

1. Topdressing. In the middle and later stage of pepper growth, the plant has many fruits and needs a large amount of fertilizer. The plots with good soil fertility and sufficient bottom fertilizer can be irrigated with 10kg water soluble fertilizer (N ∶ P ∶ K = 2 ∶ 1 ∶ 2) or urea 10kg plus potassium sulfate 7.5kg, and the plots with no organic fertilizer, insufficient topdressing and premature senescence can be irrigated with 10kg water soluble fertilizer (N ∶ P ∶ K = 2 ∶ 1 ∶ 2) or urea 10kg plus potassium sulfate 7.5kg for 2-3 times in a row.

2. Supplementary application of foliar fertilizer. Spraying 0.3% potassium dihydrogen phosphate solution or 1% superphosphate leaching solution or 1-2% potassium nitrate solution at full fruit stage and after each harvest, spraying once every 7-10 days, a total of 2-3 times, can increase the single fruit weight, make the fruit bright color, and improve the pepper grade.

3. Water management. Pepper fields that mainly harvest fresh peppers are properly watered according to soil moisture after each harvest, generally watering every 7-10 days, properly controlling water in the later stage of harvesting dry peppers, stopping watering 15-20 days before harvest, pepper is not resistant to drought and more afraid of waterlogging, such as Rain Water is less, watering should be a small number of times, if there is stagnant water should be eliminated in time, otherwise it will cause the death of fallen leaves.

Control of Diseases and insect pests of Green Pepper

1. Fusarium wilt of green pepper. Prevention and cure measures: 50% carbendazim wettable powder 500x solution, 14% copper succinate (DT) wettable powder 400x solution can be used to irrigate the root, and each hole uses about 500g medicine solution. When filling the root, dig the soil around the base of the diseased plant into a shallow disk-like pit, about 0.5 liter per plant, and then cover the soil after the solution is seeped, be careful not to hurt the root. It can also be sprayed with 50% carbendazim wettable powder 500 times or 40% polysulfide suspension 600 times. The pesticide was applied once every 6-7 days and 2-3 times in succession.

2. Green pepper virus disease. Control measures: disease-resistant varieties such as Tianza No. 2 and Zhongjiao No. 2 should be selected. Disinfect the seeds, that is, soak the seeds with 10% trisodium phosphate for 30 minutes. Clean the countryside, avoid continuous cropping, and rotate with onions, garlic, legumes and cruciferous vegetables for 3-4 years. Cultivate strong seedlings, reasonably close planting, choose a suitable sowing time, cover plastic film. Strengthen field management, timely control of aphids, prevention of high temperature and drought: reform planting patterns, implement ridge cultivation, or interplanting with tall stalk crops, in field management such as pruning and branching, hands and tools should be washed with soapy water to prevent wound infection. Silver gray film was used to avoid aphids and yellow board was used to trap aphids. Chemical control: spray 20% virus A wettable powder 500x liquid, or spray 1.5% Zhishuling emulsion 1000 times, or spray 200x antiviral agent 1, about 50kg per mu.

When planting green pepper, we should first select a good variety, and then raise seedlings, and choose seeds with high quality and good varieties. After planting, field management is also very important, such as weeding, fertilization, watering and pest control. Only after doing a good job, the green pepper will grow well and have good quality.
