Three-dimensional interplanting technique of green pepper towel gourd and coriander in greenhouse

First, cultivate strong seedlings 1. Zaofeng No. 1 (big fruit type), Sujiao No. 5, Luojiao No. 4 and other excellent varieties were selected to raise seedlings in cold beds from late October to the first and middle of November. The nursery bed selected fields that had not planted eggplant fruits and vegetables in 2-3 years. Before sowing, pay attention to the fattening seedbed, dry the seeds for 1-2 days, soak the seeds in 52 ℃ warm water for 15-20 minutes, and kill the germs on the surface. When sowing, pour enough bottom water, sow 7 grams per square meter, after sowing, shallow cover nutritious fine soil 0.5 centimeters thick, cover plastic film. Before emergence, the greenhouse was closed to increase the temperature, keeping the daily temperature 25: 30 ℃ and night temperature 18: 20 ℃. After emergence, gently remove the plastic film, and appropriate sprinkle some dry fine soil to close the cracks to promote root growth. After the seedlings were properly ventilated and humidified, the daily temperature was 20: 25 ℃ and the night temperature was 16: 18 ℃. The seedlings were divided into 10 × 10 cm plastic bowls or paper bowls at 4 leaf stage. During the overwintering period, the emphasis is on anti-freezing and disease prevention, which can be covered overnight with a shed with grass curtain or 2 or 3 layers of sunshade net, watering should be controlled in winter to avoid excessive humidity of the seedbed, and proper spraying of carbendazim, thiophanate and chlorothalonil should be applied to prevent the disease. After the Beginning of Spring, the ground temperature gradually picked up, dilute water dung was applied appropriately, and 0.2% potassium dihydrogen phosphate solution was sprayed to promote the growth of seedlings. The seedling age is 100-120 days. 2. The variety of towel gourd was white-seeded rodlike towel gourd, and the seedlings were raised in a nutrition bowl in a greenhouse in the first and middle of March. The method of soaking seeds before sowing is to soak seeds in warm water for 3 hours, then wrap them in gauze or towels and put them in 30 ℃ environment to accelerate germination. After breaking the mouth, sow 1 grain in each bowl. Before emergence, the daily temperature was 25: 30 ℃ and the night temperature was 18: 20 C. after emergence, the temperature was ventilated and humidified in time. The seedling age is 35-40 ℃, the individual plant has 3-5 true leaves, and the leaves are light green. 2. Reasonable interplanting 1. Green pepper seedlings were planted in the greenhouse on a sunny morning in the first ten days of March, with 5000 plants per mu and a row spacing of 27 × 50 cm. Apply sufficient base fertilizer 7-10 days before planting, apply 4000-5000 kg rotten organic fertilizer, 100 kg cake fertilizer, 50 kg diammonium phosphate or 45% ternary compound fertilizer 40-50 kg per mu, prepare the land, spray fluralin or dur, spread plastic film flat, and buckle shed to increase temperature. Close the shed for 5-7 days after planting, keep warm and moisturize, and promote slow seedling. 2. In late April, towel gourd seedlings were planted between green pepper rows and close to the inside of the lower foot of the scaffolding. 2 rows were planted in each greenhouse, and 250 plants per mu were planted. 3. After pulling green pepper seedlings in late July, dig up, prepare the soil and fertilize in time, apply 1520kg compound fertilizer and 1500-2000 kg mature manure per mu, and then rush to sow coriander under the towel gourd rack (using towel gourd to return to shade). Rub the cones before sowing, soak the seeds with water for 6 hours, then hang the seeds above the water surface of the well to germinate, using 6 kilograms of seeds per mu, the surface is covered with wheat straw or sunshade net after sowing, spray water sooner or later in high temperature and drought weather, keep the soil moist and promote seedling emergence. 3. Field management 1. Timely field management of green pepper, timely ventilation and humidity reduction in sunny days, proper coverage of heat preservation and frost prevention at night, due to seedling system, topdressing dilute water dung twice in sunny morning, 1000 kg per mu, to promote seedling growth. Continuous rainy weather occurs in early spring, pepper seedlings are easy to grow, should be properly sprayed with zhuangsu or paclobutrazol. In the early stage of flowering and fruiting (sitting of door pepper and expansion of pepper), high temperature injury of seedlings was prevented in sunny days, and the greenhouse temperature was controlled at 25: 28 ℃ and 15: 18 ℃ at night. According to the growth trend, 1000-1500 kg of dilute water manure per mu was applied, and manure was applied once in the next 7-10 days to promote flowering and fruiting. Results in the peak period, 20 kg of urea was forced to apply 1500-2000 kg of human and animal manure per mu, combined with pest control and disease prevention, and fertilizer was sprayed outside the root for 2 times. Remove the shed in late April and the greenhouse film in late May. 2. In the early stage of loofah extension, you can first insert a short bamboo pole next to the grid and lead the vine to climb up the bamboo pole. After the plastic film of the greenhouse was removed in late May, manage the vines and tie the vines in time to make them climb onto the scaffolding along the bamboo pole and pull them to form a network between the scaffolding; properly irrigate dilute water dung to promote the growth of melon vines. Towel gourd enters the flowering and fruiting period in the first and middle of June, it is necessary to moderate shallow ploughing and loosening soil, manage melon vines and young melons in time, and remove the lower side vines. In the full fruit period, the management can beat the old leaves and pick the weak vines frequently, sparse the redundant male buds, and pick melons frequently. In the middle and last ten days of August, the cilantro seedlings should be gradually removed to increase the light under the shed to promote the growth of coriander. 3. After the emergence of coriander, the surface mulch should be removed in time. In dry weather, water should be sprayed in the morning and evening to keep the soil moist, and mature dilute water dung should be applied every 5-7 days to promote the growth of seedlings. When the plant height is 10-12 cm, combined with watering, 7.5-10 kg urea per mu, and spraying 20ppm gibberellin solution to promote the rapid growth of coriander. If the plant height is more than 20 cm, it can be harvested in batches. In the first and middle of October, you can clear the fields with stubble and plant green vegetables. 4. Disease prevention and pest control 1. In the early stage of green pepper, carbendazim, thiophanate-methyl, trimethoprim and propofol were used to control gray mold and Sclerotinia sclerotiorum alternately, and dimethoate or aphid-killing smoke agent was used to control aphids in time. In the middle and later stage, carbendazim or methyl topiramate was used to control anthracnose, aluminum phosphate was used to prevent blight in plum rain season, 83 enhancer or virus A was sprayed in high temperature and drought weather to prevent virus disease. 2. In the early stage of towel gourd, we should pay attention to the application of dimethoate to control aphids and spray virus A500 times or 83 resistance enhancers 150 times as early as possible to prevent virus diseases. In the rainy season, 500 times of disinfectant alum or 300 times of aluminum ethyl phosphate should be used to control downy mildew. In the later stage, 1500 times of dichlorvos and ten enemies were used to kill 3000 times of mixed spray to control melon borer.
