The radish leaves of the leaves with radishes can be eaten as vegetables, mainly young plants at the time of seedling growth. The radish leaf has a very high nutritional value, is rich in vitamins and minerals, and has a fragrant and refreshing taste. In recent years, the area of ​​radish planting with leaves has gradually expanded.
Ziqing No. 1 leaf radish is a vegetable research institute in Nanjing. Therefore, Nanjing local variety Xiaohongtou is the female parent. Shandong local cultivar China radish is the father's cross, and after 5 generations of self-crossing, three lines of Y1, Y2 and Y3 are obtained. Among them, Y3 is loved by growers and consumers, and it is officially named Ziqing No. 1 leaf radish.
1 Characteristic characteristics
Plant type erect, leaf, green, leaf margin microwave serrated, hairy, petiole and root lavender. Ziqing No.1 is a special variety of leaf radish, with low fiber content, no bitter taste, good quality, heat resistance, cold resistance, convulsion resistance, 25~40 days in spring and autumn, 20~30 days in summer and autumn, and winter protection facilities. The cultivation period is 45 to 50 days. The plant height is about 20 cm, and the number of leaves is 5-6 pieces. It can be harvested. It is suitable for frying or pickling. After the plant height exceeds 35 cm, the quality is seriously degraded. The output of 667 m2 is about 2 400 kg.
2 cultivation points
The optimum temperature for the growth of Ziqing No.1 leaf radish is 5~28°C, slow growth below 5°C, freezing damage below 0°C, and high temperature and high humidity environment exceeding 30°C in summer will make the disease worse than production, so as long as it is guaranteed The temperature is suitable, Ziqing No. 1 can be planted all year round.
2.1 Organizing plots
It is better to choose a plot of non-cruciferous plants, which is fertile, easy to irrigate, and well-drained (pH 5.6~6.8). Leaf radish has a short growth period, and generally the base fertilizer can meet the fertility requirements of its growth. Therefore, 667 m2 of bio-organic fertilizer 500 kg and 45% compound fertilizer 15 kg are used as base fertilizer.
2.2 Sowing
Ziqing No. 1 sowing should avoid the frosty weather from December to February and the hot weather from July to August. It can be planted in all seasons under the greenhouse conditions. Ziqing No. 1 can be spread or broadcasted, and the sowing is planted in flat rafts, with a width of about 2 m and a line spacing of about 15 cm. The amount of 667 m2 is about 1 kg.
2.3 Field management
To promote seedling growth after emergence, 0.1% urea solution and 0.1% potassium dihydrogen phosphate solution can be used for foliar fertilizer spraying 2 to 3 times. When the temperature is high in summer, the film and shade net should be covered to reduce the sun's burning. The water is not watered to ensure the humidity is controlled and the disease is reduced. When the low temperature growth is slow in winter, the film should be insulated to promote growth. When there is frost, it should be covered with multiple layers to keep warm and freeze.
2.4 Pest Control
Leaf radish has a short growth period and less occurrence of pests and diseases. Combined with reasonable field management and insect-proof nets and other facilities, it is rarely used. Ziqing No. 1 has velvet hair and has certain avoidance effects on pests. In some open field cultivation or high-risk seasons of pests and diseases, the pests that need to be controlled and controlled by Ziqing No. 1 include Flea, Noctuidae, and Liriomyza, and sprayed with low-toxic biological pesticides such as avermectin for 2~3 times. The disease is mainly soft rot. It is treated with 72% agricultural streptomycin WP 4,000 times or 50% chlorobromoisocyanuric acid soluble powder 1000 times. It is found that the soft rot disease plants are cleared in time. The lime is disinfected around the diseased plant. Before the market, the drug will be strictly controlled according to the safety period to ensure food safety.
2.5 Harvest
Ziqing No. 1 can be flexibly harvested according to market changes. The average number of leaves is 5~9, and the harvest is better when the plant height is 20~30 cm. If the harvest is too late, the fiber will increase and the quality will decrease, which will affect the income.
The above is the cultivation technique of leaf radish Ziqing No.1, I hope to help you. If you want to know more about agricultural technology, please pay attention to the Hui Nong School!
