1 seed treatment

1.1 Soaking in warm soup: soak in the warm water of 55 °C for 15 minutes, and continue to stir, until the water temperature drops to 30 ° C to stop stirring, and then soak for 8 to 12 hours.

1.2 Drug soaking method: soak seeds in water at about 30 °C for 3 to 4 hours, and then soak them in a 1% potassium permanganate solution for 20 minutes (to prevent viral diseases) or 72.2% Plex water 800 times for 30 minutes. (Prevention of epidemics and anthrax). Rinse the water several times and then soak it in warm water at about 30 °C.

1.3 germination: the treated seeds are wrapped in a damp cloth, the moisture is controlled in the tile basin, covered with a damp cloth, placed under the condition of 28 ~ 30 °C, germination, washed once a day with warm water, 70% after 4 to 5 days The seeds are germinated and can be sown.

2 cultivate strong seedlings

2.1 Preparation of nutrient soil: Mix the garden soil of the Solanaceae vegetables and the fully decomposed organic fertilizer in 3 years, and mix evenly in a ratio of 6:4. Each 100 kg of nutrient soil is 0.3 kg of diammonium and 1.5 kg of grass ash. After mixing, it is spread in a seedbed 10 cm thick for planting.

2.2 Nursery bed disinfection: sifted nutrient soil 30 to 50 ml of formalin per square meter of seedbed, add 3 liters of water, spray the bed surface, cover the plastic film on the upper cover for 3 to 5 days, then uncover the film, after the gas is exhausted sowing.

2.3 Seeding and seedling: Before planting, the seedling bed is topped with water, and the water is required to penetrate the seedbed by 30 cm. After the water is infiltrated, a layer of nutrient soil is thinly layered, and the bed surface is leveled, evenly spread, and the nutrient soil is covered with 1.0 cm after sowing. Each square meter of seedbed is reused with 50% carbendazim WP 8g and finely ground on the bed surface to prevent smashing disease. Finally, the surface is covered with mulch to warm and protect the mites. The sowing period is early July, the seedling age is 40 to 45 days, and the planting is carried out from late August to early September.

2.4 Seedling management: After sowing, when the seedlings are 70%-80%, the mulch film should be removed in time. When there is crack in the surface, the nutrient soil should be evenly distributed (subject to the non-pressure seedlings), in order to prevent rickets and Blight, sprayed with 72.2% Plex 700 times solution. In temperature management, the daytime before emergence is controlled at 30 ° C, at night around 20 ° C, to promote rapid and tidy emergence. After the emergence of the seedlings, the temperature should be lowered, 25 ° C during the day, when the temperature exceeds the temperature, 15-20 ° C at night, control the growth of the aboveground, promote the growth of the underground, to avoid the emergence of long seedlings.

3 Scientific management, timely colonization

3.1 Fertilization: 8,000-10,000 kg of high-quality farmyard manure per mu, 60 kg of potassium sulfate, 40 kg of diammonium phosphate, 50 kg of superphosphate, fully mixed, flattened 40 cm flat, flat. Make a ridge with a width of 100 cm, an upper width of 80 cm, a groove width of 50 cm, and a height of 15 to 20 cm.

3.2 Sterilization of the shed: The shed should be disinfected before planting. Spray 500 ml of carbendazim per acre and sterilize 500 ml of phoxim. At the same time, disinfect with high temperature suffocating shed. Mix 80% of 80% dichlorvos emulsifiable concentrate per sawar room with sawdust, and mix well with 2~3 kg of sulfuric acid powder. It is ignited in 10 places, then smouldering and smouldering for a day and night, and the next morning when the wind is released until it is tasteless.

3.3 Colonization: When the sweet pepper seedlings grow to the standard size, they are planted in time. Planting density: 100 cm in large row spacing, 50 cm in small row spacing, 40 cm in plant spacing. The best time for colonization is in the afternoon, the depth of planting is the same level of seedling medium and soil surface, and the number of plants per acre is 1800-2000.

4 Post-plant management

4.1 Adjustment of temperature, humidity and light: After the planting, the shading net is used for shading, and the length of the covering time depends on the intensity of the light at that time. In order to promote the rapid occurrence of new roots, the daytime temperature is controlled at 28-30 °C, the nighttime is 15-20 °C, the relative humidity of the air is 60%-70%, the watering is settled, and the water is about 10 cm. When entering the end of October, timely warming the grass curtains to prevent cold, in order to extend the light time, properly cover the night cover, in addition, the cloudy days should also promptly uncover the straw curtain, and at the same time often wipe the shed film to increase the light transmittance.

4.2 Fertilizer and water management: After pouring the bottom water at the time of planting, it will not be watered until the fruit is placed. When the size of the pepper is the size of the walnut, combined with watering and fertilization, about 5 kg of urea per acre and 5 kg of bio-organic fertilizer. Into the fruiting period, about 7 to 10 days, water once, and apply fertilizer once every other. Watering on sunny days, not watering on cloudy days, using small water to dip, not suitable for flooding, pay attention to wind and moisture, keep the soil moist to reduce the chance of disease.

4.3 Pruning inserts: Because Hongyingda green pepper is an infinitely growing variety, it has strong growth and should be inserted into the plant. After the first branching, the axillary buds are easily germinated between the leaves of the main stems under the branches, and should be removed in time. The branches of the two branches were branched for the third time. After the second branch of the three-branched plants, there were 4 healthy branches, one leaf on the side branches and one leaf tip (one layer of 8 fruits), and so on. . In the middle and late growth stages, the diseased leaves, yellow leaves and senescent leaves in the lower part of the plant should be removed in time.

5 pest control

It is necessary to focus on prevention, early detection, early diagnosis, and early medication. Adhere to the principle of "agricultural prevention, biological control, physical control, supplemented by chemical control".

5.1 Agricultural control: cultivate age-appropriate seedlings, improve stress resistance; control temperature and air humidity, suitable fertilizer and water, sufficient light and carbon dioxide, adjust the appropriate temperature at different growth stages by releasing air and assisting heating, avoiding low temperature and high temperature Obstacles to avoid the occurrence of invasive diseases. Implemented for more than three years of rotation.

Facility protection: 40-inch insect-proof net is installed at the air outlet, and plastic film, insect-proof net and sunshade net are covered in summer to protect against rain, sun and insects, and reduce the occurrence of pests and diseases.

5.2 Physical control: Use yellow insect traps to trap aphids, whitefly and so on. Cover the silver-gray mulch to repel the mites.

5.3 Chemical control: The main diseases of sweet pepper are virus disease, epidemic disease, umbilical rot, anthracnose, etc.; insect pests mainly include aphids and spotted flies.

(1) Prevention and treatment of viral diseases: Pay attention to the prevention of mites during the whole growth period. The chemical control method is to use the phytopathetic, virus A, gram gram gram and other agents alternately after planting the seedlings, 7 to 10 days, for 2 to 3 times.

(2) Prevention and control of epidemic diseases: prevention of high temperature and high humidity. When the central diseased plants are found, they are smothered with chlorobacteria and smoked smog, once every 7 days, for 2 to 3 times, or with DuPont, fast, anti-virus, killing, etc. The liquid is sprayed and controlled.

(3) Prevention and treatment of umbilical rot: Within one month after the result, calcium phosphate or calcium oxide can be sprayed, once every 7 to 10 days from the flowering stage, for 2 to 3 times.

(4) Aphids: Fumigation with smog-killing agents, or spraying with Uranus emulsifiable concentrate and imidacloprid.

(5) Liriomyza sativae: It is controlled by drugs such as lesbian emulsifiable concentrate, green radish emulsifiable concentrate or imidacloprid.

6 harvesting

The pepper should be taken early, so as not to affect the growth and yield of the plant due to its falling. It is mainly based on the harvesting of green fruit. As long as the fruit reaches the thick flesh, the color is rich, the peel is shiny, and the fruit shape meets the standards of this variety, it can be harvested.
