High-efficiency cultivation techniques for middle sheds of tomato and celery
One, tomato 1, sowing and planting. Tomatoes are planted in the middle or late October and colonized around the Spring Festival. They are harvested from the end of March to the end of June. Select L402, cooperation 906, 908 varieties. The amount of seeds used per mu is about 20 grams. Seed beds should be selected for well-drained, fertile soil and neutral pH-quality plots. After sowing attention to adjust the temperature and humidity inside the shed. Fine preparation before planting, apply 2500-3000 kg of organic fertilizer per acre, 25 kg of compound fertilizer as base fertilizer. The shed is made into a north-south sorghum, 1-1.2 meters wide, covered with plastic film, planting, spacing 30 cm 33 cm. The temperature in the early spring is relatively low, and the shed can be covered with a shed, a shed, a small shed, and a mulch. 2, top dressing. Generally, a quick-release compound fertilizer is applied before the slow emergence to the flowering stage, and the amount of fertilizer is 10-15 kg per mu. After each spike fruit is replanted, the fruit fertilizer is re-applied. After harvesting the combined fruits, a small amount of vegetable fertilizer is applied with water. And urea, generally every time per acre topdressing dilute manure 500 kilograms or 15 kilograms of special fertilizer for vegetables, full fruit can be sprayed with 0.2% potassium dihydrogen phosphate solution. 3, pruning and pest control. When the flower is half open, the tomato nectar is concentrated at a concentration of 3010-6-3510-6. Timely pruning, leaving 3-5 spikes per plant after picking. Spray carbendazim or chlorothalonil before colonizing the tomato. Pay attention to control of gray mold and so on. Second, celery 1, nursery and colonization. The celery is planted from July to August and planted from September to October. It is listed on the New Year's Day to Spring Festival. Two varieties of Ventura and Four Seasons Celery are selected. The width of 1-1.2 meters long, 5-6 meters long, sow foot before sowing water, sowing after the cover of fine soil, pick up a small arch shed, the membrane can be used shade net or thin branches covered. The seedlings grow to 5-6 true leaves, and they can be planted when the seedling age is 60-70 days. Before planting, deep-turning sunburn, per acre applied maturity organic fertilizer 3000-4000 kg, compound fertilizer 50 kg, potassium sulfate 5 kg, strain, spacing 10 cm 10 cm. Planting water after planting. 2, fertilization. After 7-7 days of planting, 5 kg of urea was applied per acre, and then combined with watering, urea was applied once or twice a day with 10 kg of urea or 30% of human feces and urine. After planting 50-60 days per mu with 15 kg of urea plus 10 kg of special fertilizer for vegetables. Before harvesting, top dressing 1-2 times, available urea 8-10 kg per mu, 5 kg of special fertilizer for vegetables. 3, temperature and humidity control. The film is sealed from late October to early November. The temperature inside the booth is 15-20°C during the day and it is not lower than -3°C during the night. After the shed is released every morning and evening, the lowest temperature in the shed must not be lower than 5°C. 4. Pest control. The main diseases of celery are blight, leaf spot, and spot blight, which can be controlled by carbendazim, chlorothalonil, and mancozeb. The main insect pests are locusts, which can be effectively controlled by large and powerful cultivators.
