When is the latest time to plant chili?

The early growth of pepper is the germination stage, which is generally unearthed about 5-8 days after accelerating germination and sowing, and the first true leaf appears in about 15 days, and the bud is exposed at the seedling stage. The flowering period is mainly from the first flower ear to the door pepper. The fruiting period is from setting fruit to pulling seedlings. The suitable temperature for chili is between 15 and 34 degrees. The suitable temperature for seed germination is 25-30 degrees, and it takes 5-7 days for seeds to germinate. Seeds do not germinate when the temperature is below 15 degrees or higher than 35 degrees. 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.

Planting time and seedling raising techniques

Reasonable planting time and correct seedling techniques are the necessary conditions for high yield in pepper planting. Let's take a look at the planting time and seedling techniques of pepper.

1. Seedling raising time: if chili peppers are cultivated in spring in protected areas, they are usually sown and raised seedlings from January to February.

2. Seedling raising facilities: solar greenhouse can be used; or heat preservation type improved sunny bed; or plastic greenhouse, small arch shed covered with plastic film and grass curtain.

3. Seed treatment

Soaking seeds with ① agents: in order to prevent and cure common and frequent pepper anthracnose, virus and bacterial spot disease, select high-quality and high-yield varieties, first soak the seeds in clean water for 5 hours, then remove and drain them step by step and soak them in 1% copper sulfate solution, 10% trisodium phosphate solution and 2% sodium hydroxide solution for 10 minutes, to disinfect and sterilize, then remove and rinse with clean water to accelerate germination.

Soak the seeds in ② conventional warm soup: the water consumption is 5 times that of the seeds. Pour the seeds into 55 degrees water and stir immediately. After the water temperature drops to 30 degrees, soak for another 8 hours. This method has bactericidal effect on scab and Sclerotinia sclerotiorum.

4. Sprouting: wrap the soaked seeds in a wet cloth and put them in a warm place to germinate. Press 28 ℃ 30 ℃ to control 16 Mel for 18 hours and 16 Mel 20 ℃ 6 for 8 hours every day. Turn it over every 12 hours and scrub it with 30 ℃ warm water to make it heated and heated evenly to facilitate sprouting and strong. Generally, when 5Mel germinates more than 80% in 7 days, it can be cooled to 10 ℃ or placed indoors for low temperature sprouting for 8 hours, and then it can be sown.

5. Sowing: the bed soil is preferably the soil that has not planted 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. Remove the plastic film in time after the emergence of 70% of the seeds, and cover the soil with 5 mm when all the seeds emerge.

6. Interseedling: when the cotyledons of young seedlings are flattened, the weak seedlings that are overdense, crowded, diseased, malformed and poorly growing should be pulled out, and then covered with soil to protect the roots. Temperature management 25-30 degrees, in order to maintain a higher ground temperature, gradually reduce the greenhouse temperature and control irrigation 10 days before seedling emergence, in order to shorten the slow seedling time after planting.

7. Split seedling transplanting: when the seedlings grew to 4-5 true leaves, the seedlings were transplanted according to the hole distance of 7x7 centimeters, 2-3 plants per hole, covered with fine soil between the holes and filled.

After watching the planting time and seedling raising techniques of hot pepper, the following editor will introduce to you the prevention and control techniques of common diseases in the process of pepper planting.
