High Mountain cultivation techniques of Xiaojian Pepper

I. Variety selection

Pepper varieties with good yield and strong resistance were selected according to the needs of the market.

Second, cultivate strong seedlings

1. Seed treatment

Soak the seeds for 4 hours before sowing, then soak the seeds in 55 ℃ warm water for 15 minutes, stirring until the water temperature drops to 30 ℃, then soak the seeds for 8 hours and 10 hours, rinse the seed coat with liquid, rinse the shrunken seeds, rinse with clean water and dry.

2. Sowing seeds in the whole bed

It is suitable to sow at the end of March and the beginning of April. Select the fertile and dry soil that has not planted potatoes, eggplant fruits and other eggplant crops for at least 3 years as the seedbed and sow 1.2 grams of seeds per square meter to make the seedbed. Before sowing, treat the seedling bed with 1000 times liquid, pour enough bottom water, mix the seeds with fine coke ash during sowing, cover with a layer of sifted coke ash 1cm to 1.5cm thick, cover with straw, and cover with plastic film.

3. Seedling stage management

Seedling management: seedlings were carried out once or twice at the initial stage of seedling growth to remove seedlings that were too dense or too weak. The suitable temperature at seedling stage is 22: 30 ℃, and 7 ℃ is susceptible to freezing injury. The temperature is 24: 25 ℃ in daytime and 19: 20 ℃ at night is beneficial to promote root growth. Therefore, when the temperature rises to 30 ℃, the film should be uncovered in time, usually from 9 am to 10:00, and cover at 15:00 in the afternoon to keep warm. The seedbed is required to be in a dry-wet alternating state, and the general soil moisture is about 60%. During the seedling raising stage, the climate is rainy and the humidity is high, so special attention should be paid to water management to avoid rotten seedlings or growing seedlings. When the seedling bed is white, it will be watered in time, and the growth will be affected if the water is not permeable. Seedling pseudo-planting: when the seedlings grow to two leaves, the seedling spacing is 8 × 10 cm, 5% clear dung water is applied once, and Luheng will receive more foliar fertilizer to improve the seedling quality. 20% virus A500 times solution is used to prevent virus disease in seedling stage.

III. Timely planting

1. Soil preparation and fertilization

The plot with convenient drainage and irrigation, deep and fertile soil layer and eggplant crops at the end of the previous stubble was selected as the planting land. One hundred and fifty jin of quicklime is applied per mu, and then ploughing and land preparation are made, with a width of 1.3 meters. Before planting, the border should be fine and flat, the deep trench is high in the shape of a turtle's back, and a ditch 10 cm deep is opened in the middle of the border. Apply sufficient base fertilizer, 2000 kg per mu with rotten fence fertilizer and 30-40 kg compound fertilizer, and then cover the soil to be planted.

2. Reasonable close planting

When the seedlings have 8-10 true leaves and the seedling age is about 55 days, transplant after 3 p. M. in sunny day or cloudy day, two rows per row, plant spacing 33 cm, planting 3000-3300 plants per mu. When planting, try to bring soil and medicine, and irrigate the root water while planting. At the same time, dimethazone and phoxim can be added to the root water to kill soil bacteria and underground pests.

IV. Field management

1. Rational application of fertilizer and water

After returning seedlings, compound fertilizer 5: 10 kg / mu was applied to lift the seedling frame, fruit-promoting fertilizer was applied once when the first fruit began to expand, and 15 kg / mu of compound fertilizer was applied. After picking 2 batches of fruit, fertilizers should be added in time, and compound fertilizer 5 / 10 kg / mu should be irrigated to meet the nutritional needs. Results Luheng must be sprayed for 2 times more times in the early and middle stages in order to increase production and increase efficiency and improve quality. The fertilization principle of small sharp pepper is to "eat less and eat more", not to be ferocious, to prevent fertilizer damage. Small sharp pepper resistant to drought and moisture, rainy season must pay attention to clear ditch drainage, keep drainage smooth, in case of long drought should pay attention to replenish water.

2. Pruning, laying grass and inserting poles

The lateral branches below the first fruit should be erased from the vigorous growing plants, so that the roots can be ventilated and transparent. Do a good job of grass laying on the border before the plant closure, mountain grass mulching can prevent the growth of weeds, help to preserve fertilizer and water, reduce moisture and prevent drought. When the plant begins to bloom, the plant should be fixed with a stick to prevent lodging.

3. Pest control

After planting and returning seedlings, 1000 times of dimethazone solution was applied per plant, which was beneficial to the control of various root diseases. 900-1200 times of Luheng virus was used to control virus diseases, 600 times of asparagus green or 1000-1500 times of Luheng germicidal king was used to control bacterial and fungal diseases, 250 times of phoxim was used to control underground pests, and 2000 times of Luhengwangjing was used to control tobacco green insects and other pests. The use of highly toxic and high residue pesticides such as methamidophos and omethoate is strictly prohibited.

4. Timely harvest

According to the market demand, small sharp pepper is generally 7 cm in length and 0.5 cm in diameter, and it is harvested when the color is bright green. Small sharp pepper grows faster and is required to be picked every day, usually in the early morning or in the morning. The diseased fruit and deformed fruit should be removed in time, according to normal management, the general harvest time is about 3 months.
