Cherry radish is not only nutritious, but also delicate and crisp texture. It is a popular raw vegetable for people. It has strong adaptability, short growth period, rapid growth, and can be planted all year round. Especially during the Spring Festival, because people eat a lot of greasy chicken, duck, fish, meat, prefer to eat some seasonal fresh vegetables, at this time the listing of greenhouse cherry radish has become a favorite on the table. Its cultivation techniques are as follows:
I. Variety selection
After many years of production practices, cherry radish is the main planting species of Japanese cherry radish, the breed is high-yield, disease-resistant, easy to manage; bulbous color is bright, crisp and sweet meat texture, good taste, green leaves, good merchandise, and thus by the majority of vegetable farmers And consumers love it.
Second, the mouth arrangement
The main seedlings are planted in early December and early January. They are planted 50 to 60 days after planting. Because the Chinese leeks come on the market before and after the Spring Festival, they are not only economically viable, but also can be ploughed to the ground at any time to promptly plant squat cucumbers and tomatoes. Easy to arrange production. Secondly, seeds were sown in succession from February to April, harvested 25 to 30 days after sowing, interplanted in cucumbers and tomato ridges, making full use of the space and ground that the main crops did not occupy in the early stage, improving land utilization and increasing overall benefits.
Three, soil fertigation
Before planting, it is necessary to make preparations such as applying basic fertilizer, turning the floor, and sterilizing. Generally planted plots should be applied to fully mature farmyard fertilizer 5 to 6 square meters and then site preparation. The plots should be deep-turned, finely chopped, and flattened, with a depth of about 25 centimeters. Finally, the ground shall be sprayed with 1000 times of carbendazim or thiophanate-methyl liquid. If the plowing is too shallow or the soil is solid, the roots of the radish will grow poorly and easily deformed.
Fourth, precision seeding
Because of the high price of imported seeds, the farmers in the region have created precision seeding methods: use the three hooks to draw a shallow ditch in the clams, and then use the index finger to stick one seed (the seeds are clear with water to facilitate sticking to the fingers) Precision on demand, plant spacing of 4 centimeters and 10 centimeters, sowing after the cover soil, about 1 cm thick, and then gently suppress the seeds to ensure that the soil is strong, seedlings Qi and strong. Watering after sowing, to be poured thoroughly. Although the precision seeding method has some troubles, it can precisely control the plant spacing, save seeds, and reduce the production cost. It is a new technology worthy of promotion and application in production.
V. Field Management
During the whole growing period of cherry radish, special attention should be paid to the comprehensive coordination and management of temperature, light, water and fertilizer, in order to improve the quality and output of the group, so as to achieve the purpose of increasing yield and income. The close cooperation and comprehensive management of temperature, water, and fertilizer should be done well so that the aboveground and underground parts of the plant can grow in harmony. The whole growing period should be top-dressed in a timely manner and suitable for farming.
1. The temperature at seedling temperature during the day is 20~25°C, the optimum temperature during the growth period of plants is 15~20°C, and the night temperature is preferably kept at about 10°C. When the weather is cold, the curtains are shuttered immediately after sunrise (9:00) and the curtains are placed before sunset (15:00). The purpose is to store heat and heat; when the weather turns hot, it is necessary to closely monitor the temperature of the shed, and if the temperature exceeds 25°C, the air should be cooled in time.
2. The water requirement of the water and fertilizer after sowing and seedling stage is not large, keep the soil moist, quit dry, and vigorously grow the leaves to control the water seedlings. When the bulb rapidly expands, it is necessary to ensure sufficient supply of water. And no water shortage. In the production, the soil moisture content is generally maintained at 65% to 85%. The watering should be timely and uniform, and the soil should not be dry and damp. Stop watering 5 to 6 days before harvest. On the basis of applying basal fertilization, when the bulbous hypertrophy of the middle and late stages of plant growth is sufficient, the water and fertilizer should be attacked to provide sufficient nutrients. Can be combined with water flushing nitrogen, phosphorus, potassium ternary compound fertilizer 2 times, 10 kg per mu.
3. Pest control No pests and diseases occur in winter basically. However, after entering in February, the room temperature gradually increased, to monitor the occurrence of roundworm, spotting, and whitefly. In production, prevention is the main method, and comprehensive measures can be taken to control pests through comprehensive measures such as temperature, humidity, and light management. Chemical control should use low-toxicity, high-efficiency, low-residue biopharmaceuticals, such as imidacloprid, avermectin, and bromithriolide, and should be used routinely.
