How to grow chili in winter

Chili is a kind of vegetable with spicy taste, and the sowing and harvest season is generally spring and summer, so how to grow chili in winter?

First, the basic introduction of chili

Pepper is an annual or limited perennial of Solanaceae, also known as horned pepper, long pepper, vegetable pepper, lantern pepper and so on.

The early growth stage of pepper is the germination stage, it is generally unearthed about 5-8 days after accelerating germination and sowing, the first true leaf appears in about 15 days, and the bud is exposed to the seedling stage.

The seedling stage requires a higher temperature, 25-30 degrees during the day, 15-18 degrees at night is the best, the seedlings are not resistant to low temperature, we should pay attention to cold prevention. Chili peppers at 35 degrees will cause flowers and fruits to fall.

How to grow chili peppers in winter?

The main results are as follows: 1. The suitable growth temperature of pepper is 25 ℃-30 ℃. If the local winter temperature is low, it should be planted in the greenhouse.

2. Select the varieties with strong adaptability, disease resistance and high yield, and then soak the seeds and accelerate the germination.

Yuejiao No. 3 pepper and Fukang No. 1 pepper cultivated by vegetable Institute of Guangdong Academy of Agricultural Sciences are more suitable pepper varieties.

The detailed steps of seed soaking and budding treatment are as follows: soak the pepper in water for 5 hours for 6 hours, wash it clean, soak it with 1% copper sulfate solution for 5 minutes, and remove it for moisturizing and budding.

The day before sowing, you should pour enough bottom water and apply appropriate amount of base fertilizer, and then spread the seeds evenly on the seedbed.

3. Pepper seedlings can be planted when they grow to a certain extent and transplant according to the appropriate density.

Before planting, 5000 kg of high-quality farm manure and 15 kg of diammonium phosphate should be applied to each mu of land preparation. Rise from a high border with a width of 1 to 1.5 meters.

When the seedling grows to about 10 cm, under the condition of suitable environment, it can be moved to the field according to the row spacing of 33 × 33 cm, and then irrigated with fixed root water.

4. Field management such as slow seedling, fertilization, pruning and watering should be carried out after transplanting.

Slow seedling: mainly to heat preservation and moisturizing, if there is no plastic film mulching, you can carry out mid-tillage. After slowing down the seedlings to before flowering, water reasonably according to the weather conditions, and appropriate watering during drought to keep the soil moist. Before sealing the ridge, it is necessary to cultivate the soil and protect the root, and water it after cultivating the soil.

Fertilization: foliar spray of 50 grams of potassium dihydrogen phosphate with 15 kilograms of water can be used to enhance photosynthesis, promote deep root system, promote the healthy growth of plants, and enhance the disease resistance of plants.

When the door pepper grows to 3 cm, combined with ploughing for fertilization, 200 grams of rotten dung dry powder and 10 kilograms of urea are applied per mu. Topdressing should be carried out after each fruit harvest, and nitrogen, phosphorus and potassium should be used together. 15-20 kg compound fertilizer should be applied per mu and poured with water to supplement tree nutrition.

Pruning: cut off the inner bore branches and old and diseased branches. Leave 2 leaves above the third grade branch for sharpening. Remove the old and diseased leaves in the lower part to reduce nutrient consumption. At the same time, the soil should be cultivated again to promote new roots and prevent lodging.

Watering: pepper is strict with conditional moisture. It can neither tolerate drought nor waterlogging. I like dry air conditions. It should be watered according to the growth of hot pepper.
