Four cultivation models based on spring radish and pepper

Spring radish-pepper-towel gourd-green garlic four kinds of four-harvest cultivation model, the annual net income is 8800 yuan, the technology is not complicated, is a good vegetable multiple cropping model. The main technical points are as follows: spring radish variety selection: select excellent radish varieties with high yield, good quality, cold tolerance and bolting tolerance, such as Texin Baiyuchun in South Korea. Soil preparation and fertilization: select plots with deep, fertile and loose soil, at the same time, fine farming and adequate base fertilizer should be applied, and then land preparation should be made. On demand: sow 1-2 seeds in each hole, cover the plastic film after sowing, and buckle the greenhouse. Field management: when the cotyledons were flat, the membrane was broken and the seedlings were exposed. When there were 3 or 4 true leaves, there were interseedlings and supplementary seedlings, leaving 1 plant in each hole. Close the greenhouse before March, keep the temperature high, cover some cold-proof materials to prevent frost damage if necessary, and ventilate properly as the temperature rises after March. Keep the border moist and have an adequate supply of water. Pepper variety selection: choose early-maturing, disease-resistant, high-quality big-fruit pepper varieties, such as Luojiao 98A. Sowing and raising seedlings: raising seedlings in greenhouse. Before sowing, soak the seeds in 10% trisodium phosphate solution for 15 minutes, then soak them in 55 ℃ warm water for 20 minutes and 30 minutes. Soil preparation and fertilization: after the radish is harvested, apply sufficient base fertilizer combined with soil preparation. Colonization: about 4000 plants. When planting, make a hole in the plastic film and transplant. Temperature and humidity in the shed: the daytime temperature is required to be 25 ℃ ~ 28 ℃, and the air relative humidity is 50% and 60%. After transplanting, do not ventilate, so that the shed to maintain high temperature and humidity, to promote early survival. After survival, start ventilation, adhere to daily ventilation, usually 8 ∶ 00 in the morning, 4 ∶ 00 in the afternoon to cover the shed, overcast and rainy weather should also be properly ventilated to reduce humidity. Extra-root topdressing: after survival, 0.1% potassium dihydrogen phosphate solution was sprayed as foliar fertilizer, once every 5-7 days. Towel gourd variety selection: select varieties with uniform thickness, green color, thick meat and high quality. Raising seedlings: using greenhouse and nutrition bowl to raise seedlings. Colonization: when the seedlings grow to 4 or 5 true leaves, they are planted next to the furrows in the pepper field. Scaffolding: when the towel gourd main vine is 50 cm ~ 60 cm long, it is generally built into a flat scaffolding. After scaffolding, each plant inserts a bamboo pole, artificially induces the vine, binds the vine to assist the melon stem on the shelf, at the same time, each plant is selected to leave 1 or 2 strong vines on the shelf, the other side vines are removed, and generally no longer pick the vines, but in the middle and later stages of towel gourd growth, it is necessary to adjust the position of the main side vines and cut off some old leaves and small forked branches to ensure ventilation and ventilation. Increase the rate of melon sitting. Strengthen fertilizer and water management: leaf vine long-term water demand, especially in the high temperature and drought season, after sitting melon combined with fertilizer and frequent watering to ensure that the soil is moist. Green garlic variety selection: choose "Chengdu Ershui early". Soil preparation and fertilization: immediately after the pepper harvest, turn the soil deeply, cover the plant ash 2 cm thick after sowing, and irrigate in time. Fertilizer and water management: before emergence, if the soil is dry, water should be replenished to promote early emergence. If you encounter drought during the growing period, you should irrigate and keep the soil moist. At the same time, topdressing 2-3 times, each time 2000 kg of rotten dung water or 15-20 kg of urea.
