The cultivation of green pepper, loofah and parsley by using the three-dimensional intercropping technology in greenhouse can greatly improve the utilization rate of land and greenhouse, and increase planting efficiency to increase planting income. The following small series will introduce the high-efficiency three-dimensional intercropping technology of green pepper, loofah and parsley in the greenhouse. The content is only for the reference of the majority of growers.
First, cultivate strong seedlings
1. Green peppers are selected from large fruit-type varieties, and they are kept in cold bed from late October to mid-November. The seedbed is selected for a field that has not been planted with solanaceous vegetables within 2-3 years. Before the sowing, pay attention to the fertilization seedbed, soak the seeds for 1-2 days and soak them in warm water of 52 °C for 15-20 minutes to kill the surface bacteria. When planting, the bottom water is poured, 7-8 grams per square meter, and the shallow cover nutrient fine soil is 0.5-1 cm thick after sowing, covering the mulch. The greenhouse was warmed before emergence, and the daily temperature was 25-30 °C and the night temperature was 18-20 °C. Gently remove the mulch after emergence and spread some fine soil to bridge the cracks to promote root growth. After the seedlings are properly ventilated and dehumidified, keep the daily temperature 20-25 ° C, night temperature 16-18 ° C. The 3-4 leaf stage seedlings were placed in a l0 x 10 cm plastic file or paper tube. During the winter, the focus is on anti-freezing and disease prevention. It can be covered with a greenhouse shed with straw curtains or 2-3 layers of shade nets. In winter, watering should be controlled to avoid excessive humidity in the seedbed. Suitable spraying of carbendazim, thiophanate, and hundred The fungus clears the disease. After the spring, the ground temperature gradually rises, and the plant regulator is appropriately applied to cultivate the strong seedlings, and the anti-reverse water-preserving regulator is sprayed to promote the growth of the seedlings.
2, loofah varieties choose white seed stick-shaped meat loofah, in the middle of March in the application of greenhouse sheds for nutrition and nursery. Soaking seeds before germination, the method is to soak seeds in warm water for 3 hours, then wrap them in gauze or towel and germination in a 30 °C environment. Before the emergence of seedlings, keep the daily temperature of 25-30 ° C, night temperature of 18-20 ° C, and timely ventilation and dehumidification after emergence. The seedlings are 35-40 ° C, 3-5 true leaves per plant, and the leaves are green.
Second, reasonable interplanting
1. Green pepper green pepper seedlings were planted in the greenhouse in the early morning of March, planting 5000 plants per acre, with a row spacing of 27×50 cm. Apply base fertilizer 7-10 days before planting, apply 4000-5000 kg of decomposed organic fertilizer, 100 kg of cake fertilizer, 50 kg of diammonium phosphate or 40-50 kg of ternary compound fertilizer, and prepare for spraying or spraying flurin or Duer, flat mulch film, buckle shed to increase temperature. After the planting, it will be closed for 5-7 days, and the moisturizing and moisturizing will promote the slow seedling.
2, loofah in late April will be loofah 秧 planted in the green pepper line and close to the inside of the scaffolding foot 20 cm, each greenhouse to plant 2 rows, acres planted 220-250 plants.
3, parsley in late July, after the green pepper pull, timely digging, soil preparation, fertilization, 15-20 kg of compound fertilizer applied per mu, 1500-2000 kg of decomposed manure, and then smashed coriander under the loofah frame (using loofah to return shade). Before sowing, the fruit is soaked in water for 6-8 hours, and then the seeds are suspended above the water surface of the well to germination. The seed is 6-7 kg per acre. After sowing, the surface is covered with wheat straw or shading net. The hot and dry weather persists sooner or later. Spray water to keep the soil moist to promote emergence.
Third, field management
1. Green pepper timely management in the field, timely ventilation and dehumidification on sunny days, proper coverage of frost and frost at night, can be suitable for seedlings, and choose to apply 1-2 times of high-potassium and high-calcium fertilizers on sunny days in the morning, 8-10 per acre. Kilograms to promote seedling growth. In the early spring, there is continuous rainy weather. The pepper seedlings are easy to grow, and the appropriate amount should be sprayed with the helper or paclobutrazol. At the beginning of the flowering result (the door is sitting on the pepper, the pepper is inflated), the high temperature is prevented from being damaged by the high temperature, the temperature of the shed is controlled at 25-28 ° C, and the night is 15-18 ° C, and the high potassium and high calcium fertilizer can be applied according to the growth potential. 10-12 kg, after 7-10 days, once again, it will promote the flowering result. As a result, 10-15 kg of high-potassium and high-calcium fertilizers were applied per acre during the peak period, and combined with pest control work. The shed was removed in late April and the greenhouse film was removed in late May.
2, in the early stage of the loofah loofah, you can first insert a short bamboo raft next to the grid, and lead the vines to climb the bamboo pole. After the removal of the greenhouse film in late May, the vines and vines were timely arranged, and the rafts were climbed along the bamboo rafts to form a net between the scaffolds; the dilute water was appropriately poured to promote the growth of the vines. In the middle of June, the loofah enters the flowering stage, and it is necessary to moderately plough the loose soil, and timely remove the lower side vines from the melon and the young melon. In the fruit period management, the old leaves and the weak vines are diligently beaten, and the excess male flowers are diligently collected. After the coriander seedlings are in the middle and late August, the vines should be gradually removed to increase the light under the shed and promote the growth of coriander.
3. After the emergence of coriander, the surface covering should be removed in time. The dry weather should be sprayed with water in the morning and evening to keep the soil moist. Plant growth regulators should be applied every 5-7 days to promote seedling growth. When the plant height is 10-12 cm, it is combined with watering, applying 5-8 kg of organic fertilizer per acre, and spraying 20ppm gibberellin solution to promote the rapid growth of coriander. Plant height of 20 cm or more can be harvested in batches. In the middle of October, you can plant green vegetables in Qingtian.
Fourth, disease prevention and control
1. In the early stage of green pepper application, carbendazim, methyl thiophanate, keering, and chlorhexidine were used to control gray mold and sclerotinia; and imidacloprid or acetamiprid smog was used to control aphids in time. In the middle and late period, carbendazim or thiophanate-methyl is used to prevent and treat anthrax. In the rainy season, attention should be paid to the prevention of epidemics by spraying aluminum phosphate, high-temperature and dry weather, 83 anti-agent or virus A to prevent viral diseases.
2. In the early stage of loofah, pay attention to the application of imidacloprid to control aphids, and spray the virus A500 times or 83 antagonists 150 times early to prevent viral diseases. In the rainy season, it is necessary to apply 500 times of anti-virus cockroaches or 300 times of ethyl phosphide-aluminum to prevent downy mildew. Later application of avermectin 1500 times plus chlorpyrifos 1000 times mixed spray to prevent melon.
The above is a high-efficiency three-dimensional intercropping technology of green pepper, loofah and parsley in greenhouse. I hope to help you. If you want to know more about agricultural technology, please pay attention to the Hui Nong School!
