The fruit is bell-shaped, the fruit is large and long, the fruit is 16-18 cm long, the fruit is 9 cm wide, and the average fruit weight is 260 g. The number of fruits per plant is about 38. The fruit turns from green to red, the flesh is thick, and it is extremely resistant to storage and transportation. High resistance to tobacco mosaic virus and low temperature tolerance.
Second, the anniversary of cultivation techniques
(1) Cultivate strong seedlings
1. Determine the sowing date. According to the physiological characteristics of the colorful peppers and the golden age of the market, it is advisable to sow in the middle to late July to early August.
2. Build a seedbed. Choose a plot with high ground and good drainage, and grow the seedlings of 8 to 10 meters in length, 1.5 meters in width and 0.15 meters in depth to level the surface. Use a thin bamboo raft to build a small arch shed with a length of 1.0 m and a width of 1.8 m on the surface of the coffin. Use an insect-proof net with a width of 4 meters, fix it on the small arch shed, and cover the silver-white sunshade net with a width of 4 meters and a shading rate of 70%. Dry the garden soil and fully decomposed organic fertilizer, and then press the sieve. The ratio of 4:1 is made into nutrient soil, and 1 kg of superphosphate is added to the nutrient soil per metre, 500 g of carbendazim, stirred evenly, and placed in a nutrient bowl with a size of 8 cm and 10 cm, neatly placed Placed in the nursery, the gap between the nutrients is filled with soil.
3, soaking seeds and germination, soak the seeds in the sun for 1 to 2 hours, soak in water for 55 to 60 ° C for 10 minutes, then into the warm water of 30 ° C for 6 to 8 hours, wrap the seeds in a damp cloth and put them in 28 After germination at ~30 °C, more than 50% of the seeds are white, then they can be sown.
4. Seeding method Before the sowing, the seedbed should be poured with the bottom water. After the water seeps, the single seed is planted. The seeds can be placed in a nutrient bowl, covered with soil 1.5 cm, first covered with a plastic film, then covered with a sunshade net, compacted around, the shed temperature is maintained between 30 ~ 35 ° C, pay attention to moisturizing, rain.
5, seedling management 2 to 3 days after the emergence of the seedlings, remove the plastic film, with DDT and wheat bran mixed into a poisonous cockroach, removed from the nursery and surrounding, to prevent pests. Cover the film on the small arch shed before the rain to prevent the seedlings from being rained. After emergence, attention should be paid to ventilation. The seedbed should be sprayed with 72.2% of Plex water 600 times to prevent rickets. The insect-proof net must be pressed to prevent mites and locusts from entering the virus. When the temperature exceeds 35 °C, spray the water on the sunshade net with a sprayer to cool down. When the seedling grows to 6 leaves and 1 heart, it can be colonized.
(2) Proper planting
1. Apply 15 days before the base fertilizer and pesticide planting, apply 8000-10000 kg of fully decomposed organic fertilizer, 50 kg of diammonium phosphate and potassium sulfate compound fertilizer, and 5 kg of boron-zinc micro-fertilizer every 667 m2. At the same time, apply 812 granules of 2 kg, if the wireworm in the shed, use 1% to 1.5 kg of 10% gram of phosphorus granules per 667 m2, spread the above fertilizers and pesticides evenly on the surface, and then deepen 40 cm or more, flattened and fine.
2, cover the shed film 7 to 10 days before the high temperature stagnation planting, the film should use composite EAV film or no drop film, close all the air vents in the greenhouse, and hang the greenhouse for 3 to 4 days in a sunny day. Sterilization, open the ventilating ventilation after shacking, and then fasten the sunshade net. The shading net should use a shading rate of 50% or more. The front and rear vents should be fastened with a pest net of 1 m wide to prevent virus diseases caused by insects. Wait.
3, ridge ridges before planting according to the large line 80 cm, small line 60 cm, plant spacing 45 cm line spacing cross-digging, and 1.8% Effort emulsifiable milk 1000 times solution spray control root-knot nematode.
4, colonization. The planting time is from late August to early September. When planting, you should choose cloudy or sunny days to plant after 3 pm. And use 60 times 50% of carbendazim medicinal soil 75 kg evenly into the colonization hole, the soil and the soil in the hole are fully mixed and then planted. The soil of the seedling is slightly lower than the surface of the sorghum. After planting, the water can be directly poured or first After pouring for 2 to 3 days, pour large water, depending on the humidity of the greenhouse soil. Before watering, spray 72.2% Plex 800 times solution, 72% streptomycin 4000 times solution and Wanling and other insecticides. When the ground is semi-dry and semi-wet, it should be timely.
(3) Management after planting
1, the temperature before the slow seedlings is generally maintained at 28 ~ 32 ° C, should not be too high, more than 32 ° C, ventilation and cooling, and within a day higher than 30 ° C time should not exceed 3 hours, 9 to 10 months should be the maximum ventilation, but encountered The rain closes the vents in time.
2, the temperature after the slow seedling control is controlled at 25 ~ 30 °C, in order to promote the expansion of the roots, keep the soil wet and not sticky, should be poured in small water. 7 days after the slow seedling, 72.2% of Plex water, 7051 Liangtian No. 1, chelated micro-fertilizer, etc. were used to control pests and diseases, promote plant growth and increase resistance. The double-bar pruning method is used to form a bifurcated branch, and the branch and the first side branch are retained, and the following side branches are all removed.
3. During flowering and fruit setting. 22 to 26 ° C during the day and 15 ° C during the night. After the plants are closed, the leaves and leaves below the door pepper are all removed, the ground is covered, the ground temperature is raised, the humidity is lowered, the reflective curtain is hung on the back wall of the shed, the light intensity at the back of the shed is raised, and the frame is raised to prevent the plants from lodging. . In this period, if the temperature is too low, you can use (25 ~ 30) 10-62, 4-D, PCPA or naphthalene acetic acid spray 1 or 2 times before and after flowering, have a certain effect on preventing falling flowers, but use Beware of phytotoxicity when 2,4-D. Watering advocates combined with topdressing to pour small water under the membrane. Each time the fruit is harvested, the topdressing is performed once. The foliar topdressing can be carried out with 0.5% urea plus 0.2%-0.3% potassium dihydrogen phosphate.
4, pest control 1 virus disease. The sweet pepper virus disease is mainly transmitted by aphids and whitefly, and can be controlled at any time by using 1500 times of net or chlorpyrifos; after planting the seedlings, 20% virus A500 times plus 600 times chelated state micro-fertilizer (or 600 times good field) No. 1) or 1.5% phytopathogenic 1000 times plus 600 times chelated state micro-fertilizer (or 600 times Liangtian No. 1), once every 7-8 days, even sprayed 3 to 4 times. 2 root rots. After colonization, the roots were filled with 600 times of root disease or 50% carbendazim plus ethylphosphonium aluminum manganese zinc 600 times, 7 to 8 days, and then irrigated 2 to 3 times. 3 knot nematodes. After planting, the roots were irrigated with 1.8% Aifuding 1000 times solution for 10 to 15 days, and then irrigated for 2 to 3 times.
