Listed cherry radish planting technology for the Spring Festival
Cherry radish is not only nutritious, but also delicate and crisp texture. It is a popular raw vegetable for people. Its adaptability, short growth period, rapid growth, can be planted throughout the year, especially during the Spring Festival, the price is high, and the efficiency is good. The cultivation techniques are now described as follows:
I. Variety selection
Cherry radish is the main planting species of Japanese cherry radish, etc. The variety is high-yield, disease-resistant, easy to manage; bulb color is gorgeous, crisp and sweet meat, taste good, leaves green, good merchandise.
Second, the mouth arrangement
The main seedlings are sown in early December to early January. They are harvested 50-60 days after planting. Because the Chinese leeks come on the market before and after the Spring Festival, they are not only economically viable, but they can also be used for planting the cucumbers and tomatoes. Easy to arrange production. Secondly, the seeds can be sown in succession in 2-4 months, harvested 25-30 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 period, improving land utilization rate and increasing the 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 manure 5-6 cubic meters and then site preparation. The plots are to be deep-flipped, fine-grained, and flattened, with a depth of about 25 cm. Finally, the ground surface was sprayed with 1000 times carbendazim or thiophanate-methyl liquid for sterilization. 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 production must adopt precise seeding methods: first, draw a shallow ditch in the cocoon, and then use the index finger to stick a seed (the seed is clear with water to facilitate sticking to the fingers). The row spacing is 4 cm and 10 cm. After sowing, the cover soil is about 1 cm thick, and then gently suppressed to ensure that the seeds are energetic and the seedlings are vigorous and vigorous. Watering after sowing, to be poured thoroughly. Although the precision seeding method is troublesome, it can precisely control the plant spacing, save seeds, reduce production costs, and eliminate the use of seedlings in the later period. It is a technology worthy of promotion and application in production.
V. Field Management
During the whole growth 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 yield of the group, so that the plant's above ground and underground parts can coordinate growth, so as to achieve the purpose of high yield and income.
1. Temperature. The optimum temperature during seedling daytime is 20°C-25°C, the optimum temperature during the growing season is 15°C-20°C, and the night temperature is preferably kept at about 10°C. When the weather is cold, the curtain is rolled at about 9 o'clock in the morning and the curtain is at 3 o'clock in the afternoon. The purpose is thermal insulation. When the weather turns hot, it is necessary to monitor the temperature of the greenhouse closely. If the temperature exceeds 25°C, the temperature should be released in time.
2. Water and fertilizer. After sowing and seedling stage, the water requirement is not large, keep the soil moist, not dry, and the leaves vigorously grow to control the water seedlings. When the bulb rapidly expands, it is necessary to ensure sufficient supply of water. In the production, the soil moisture content is generally kept between 65% and 85%. The watering should be timely and uniform, and the soil should not be dry and damp. Stop watering 5-6 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 the winter. However, after entering the month of February, the room temperature gradually increased and it was necessary to monitor the occurrence of aphids, spotted whitefly and whitefly. In production, prevention is the main method, and comprehensive measures can be taken to strengthen the management of temperature, humidity, and light, and to prevent the occurrence of pests. Chemical control should use low-toxicity, high-efficiency and low-residual biological agents, such as imidacloprid, abamectin, and bromithrin.
Flower shape design origin from the principle of aerodynamics, it reduces the surface area that impedes the flow of air from the air supply ceilings, resulting in a less turbulent flow underneath the light; the flower shape also can suit to mobile type, can choose straight arm or tube arm; the battery inside of the lamp base can last long for 8 hours, the flower lamp spot diameter is adjusted by electric, the brightness of different LEDs is adjusted automatically to change the spot size, which will avoid the possible occurance of mechanical malfunctions;
