American Bailey sweet pepper has strong growth potential, compact plant type, smooth fruit surface and green color. The meat is 0.6-0,7 cm thick, and the sweetness is crisp and the quality is good. The single fruit weighs 100-200 grams and the maximum fruit weight is 400 grams. Because of its large flesh and thick, the brightness is good. It is resistant to transportation and has become a hot commodity in Hong Kong and Guangdong markets. Pollution-free cultivation of American sweet peppers is a project with low investment, quick results and high returns. From 1999 to 2007, the planting area of ​​our county was 3,390 hectares. According to the survey, the output per hectare is generally 30,000-37,500 kg, the high is 45,000-52,500 kg per hectare, and the average output value is 46,500-75,000 yuan per hectare.
First, cultivate strong seedlings
The seedlings of sweet pepper enter the flower bud differentiation stage when they are unfolded from 2--3 leaves. The flower buds that make up the sweet pepper yield are differentiated at the seedling stage. Therefore, the cultivation of roots is developed, the stems are thick, the leaves are stretched, the color is thick green, the flower buds are full, and the heart green leaves are strong seedlings, which is the basis for the high yield and quality of sweet peppers. We must carefully grasp all aspects of nursery.
Sowing
(1) Sowing period: The planting period of low altitude (below 300 meters) is in mid-November, and the medium and high altitude areas can be planted until March.
(2) Selection of seedlings: In winter, it is best to prevent low temperature and cold current, and the north side of the site has a natural barrier. Can make full use of solar energy, increase temperature and ground temperature. Form a good microclimate, the soil should choose good permeability and permeability. A convenient plot for irrigation and drainage.
(3) soaking seeds and germination: a, disinfection and soaking seeds. Soak the seeds in cold water for 3-4 hours, then soak them in 0.1% potassium permanganate solution for 15 minutes, wash them and soak them for 6-8 hours at room temperature. Pick up and wrap them in wet gauze, and germination at 25-30 °C. 60% of the seeds can be sown when they are exposed. b, warm and disinfection of the species. Soak for 3 to 5 hours before soaking (not suitable for exposure to sunlight), then soak for 50 to 55 minutes with warm water at 50-55 ° C for 10 to 15 minutes. Stir constantly, then soak for 6-8 hours at room temperature. The germination method is the same as above.
(4) Sowing: The soil in the seedbed should be broken and flattened, and a small amount of decomposed bovine pig manure should be applied. It is necessary to plant 10 m of seedling bed per acre of sweet pepper. 50% smear manganese zinc, 50% carbendazim, 30% succinic acid copper sulphate 100g mixed with 30kg of sifted fine soil should be used, and 1/3 of the soil should be removed from the glutinous rice before sowing. /3 The soil is covered with seeds, and the straw is irrigated with water, and the small arch shed film is used to keep warm.
2. Seedling management
(1) Sowing to emergence: The temperature is controlled at 25-30 °C during the day and 18-20 °C during the night to keep the soil moist and prevent drought and excessive humidity. Whole seedlings can be produced around 7-10 days after sowing. The straw is gradually removed when the seedlings emerge.
(2) emergence to seedlings: When the first true leaf appears, the temperature control is 23-28 R2. Night temperature control 16-19 ° C, sunny day at noon brown film allows the seedlings to see more sunshine, in the evening must be tightly protected from cold and frozen. In case of low temperature below 0 °C, the insulation measures of double-layer film straw should be taken in time to reduce the freezing damage, and the seedlings can be divided into 2 to 3 true leaves.
(3) Sub-seedling planting: 3000 pieces of 8cm × 8cm nutrient bowls (bags) per mu, mixed with nutrient soil 10~15 days before seedlings, fertile paddy soil accounted for 75% in nutrient soil, and composted organic fertilizer accounted for 75%. 15%, fire burned soil accounted for 10%, plus ternary compound fertilizer, superphosphate, each 3-4 kg, plus 50% arsenic manganese Zn, 50% carbendazim, 30% succinated copper, 300 grams each Mix well, mix well, and compile the seedlings. The seedling time is mastered in the 2-3 true leaf fashion 钵 (bag) fake plant, and each 钵 (bag) has a false value of 1 seedling. Seedlings, weak seedlings and poor seedlings should be removed when seedlings are divided.
Second, the whole planting
Before the selection, the crops were not planted, and the soil was fertile. It is convenient for irrigation and drainage, sandy loam or loam with good water permeability and permeability. Before the plough, 50-75 kg of lime is applied to the soil for disinfection. 190 kg of fermented organic fertilizer, 50 kg of vegetable special fertilizer. 100 kg of high-efficiency bio-organic fertilizer of Kawada, 25 kg of superphosphate, 1.5 kg of borax, 1.s kg of magnesium sulfate, and 1,5 kg of zinc sulfate. The deep groove sorghum is used, the width of the glutinous rice is 85 cm, and the height of the glutinous rice is 30 cm. Before the planting, the mulch is sprayed with 48% of the herbicide 100-150 g and 60 kg of water. Then the black mulch is spread. When the seedlings 6-8 leaves are true leaves, they are planted in two rows, and the plant spacing is 30 cm × 40 cm. The planting is 2000-2500 plants. According to the test. Covering the black plastic film from February 25 to mid-May, with different soil layers within 15 cm, the daily average temperature is increased by 4.2-4.5 °C than the open field. Due to the protective effect of the plastic film, the number of irrigation times is reduced by 3-4 times, which reduces the ground temperature after planting. Reduce the adverse effects. The width of the mulch film is 1.2 meters, and the acre needs about 10 kilograms. The time of uncovering the film depends on the temperature of the ground and the growth of the plant. Generally, it is suitable before and after the awning (after the rainy season), and the soil is fertilized in time after the film is uncovered.
Third, fertilizer management
Applying the flower fertilizer, after the first bud, the per mu can be used to apply 500 kg of manure and three kilograms of compound fertilizer to 10 kg of water. According to the situation, top dressing 1-2 times. Re-apply fruit fertilizer, apply 10 kg of compound fertilizer per mu per time, add 10 kg of urea to water if necessary, and apply 1 time of topdressing per harvest. Keep the soil moist on the water pipe. In the rainy season, there should be more drainage. Drainage should be done to control the soil water content. If it is too dry, it can be used for furrow irrigation. The water depth is 2/3 of the height.
Fourth, plant adjustment
As the plant grows, side branches occur from bottom to top, and the side branches are smashed in time when they are 3-4 cm. Practice has proved that the leaves below the cotyledons and the door peppers are not yellowed. They will not be removed without wilting. The lateral branches of the peppers to the pepper nodes should be removed. The germination of the third and fourth layers depends on the growth and fruiting of the plants. Snoring is an effective measure to increase production. It is advisable to retain 8-15 fruits within the 4th layer. If the temperature is not high in the later period, the plant grows vigorously, and the fifth layer of fruit branches can bear fruit. In general, the top layer is topped after the fifth layer. Plant adjustment should be carried out on sunny days. After pruning, it is necessary to spray drugs to prevent pests and diseases. If the temperature is high, the fifth layer can retain some branches and leaves to prevent sunburn.
Five, pest control
In a reasonable rotation, seed, seedbed soil and kneading disinfection, clean gardening, fitness cultivation, according to the occurrence of pests and diseases in a timely manner. In the seedling stage, there are mainly rickets, blight, and cockroaches. The main fruiting stages are blight, bacterial wilt, bacterial leaf spot, viral disease, umbilical rot, aphids, Spodoptera litura, and tobacco budworm.çŒ ç—… disease, blight, can choose green enjoy No. 1 3000 times liquid or 70% dixon 700 times liquid or 72, 2% Plex 400 times liquid control: bacterial blight can choose 72% agricultural streptomycin 3000 Double or new phytomycin 3000 times liquid or 30% succinic acid copper acid 500 times liquid or 77% can kill 500 times liquid control; bacterial leaf spot can choose 72% agricultural streptomycin 3000 times liquid or 30 % succinate copper acid 500 times liquid or 77% can kill 500 times liquid or 1:1: 240 Bordeaux liquid control: the disease can be selected with 69% Anke Mn-Zn 1000 times liquid or 58% Redomroic Manganese zinc 500 times Liquid or 72% gram dew 700 times solution or 72.2% Plex 500 times solution control; virus disease on the basis of treatment and prevention of disease, you can choose 20% virus A500 times solution or 3.85% virus Baker 500 times solution or 1.5% Plant disease 1000 times liquid plus 0.15-0.3 mg / kg brassinolide control; umbilical rot after the fruit is sprayed with 1% superphosphate solution, spray once every 10 days; when the seedling bed is done, Spray with 40% phoxim 1000 times solution. Then seeding, seedling growth period can be used 5 kg of sauteed wheat or glutinous rice, add 0.15 kg of 90% trichlorfon plus appropriate amount of water and mix well into a poison bait to kill, apply 1.5-2.5 kg of bait per acre of seedlings: aphids Control with 10% I than porphyrin 1500 times solution: Spodoptera litura, tobacco budworm can choose 5% Regent 2000 times solution or 2.5% Kung Fu 1000 times solution or 10% to remove 1500 times solution or 25% Diflubenzuron 1500 Double solution plus 4.5% beta-cypermethrin 1500 times solution.
