Fertility period 70 to 80 days. Leaves clusters erect, mosaic, dark green. The fleshy roots are long cylindrical, 40-45cm long, 6.5cm in diameter, and a single root weight of 1000g. The skin is white, smooth and delicate, and extremely shiny. The meat is white and crisp, sweet, suitable for fresh food and processing. The variety has strong disease resistance and high yield potential. It is suitable for cultivation in late autumn in northern China and in post-autumn arch sheds.
Seed production techniques
The female parent of the variety is spring radish and the father is autumn radish. There are two major technical difficulties in seed production. One is to solve the problems of spring radish twitching and flowering, and the second is to solve the problem of poor flowering time.
1. Strictly separate distances. Radish is cross-pollination crops, insect-borne flowers, natural hybridization rate is high, the requirements of the system of production and other radish varieties to maintain 1500 ~ 2000m distance.
2. Seed selection. In early September, the mother planted the seedlings and the seedlings were sowed in a row with a ditch of 30 cm. At the seedling stage, the diseased plants, miscellaneous plants, and weak plants were removed according to hypocotyl color, plant growth, height, leaf shape, leaf color, etc., and strong seedlings were selected. At the time of harvesting in early November, in combination with the root shape and skin color of the fleshy root, the spurious strains that did not meet the characteristics of the parent were eliminated. Leave the selected plant leaves at 7 to 10 cm to cut off and plant them directly into the greenhouse for winter. Reserve 3 parents for each line of planting.
3. The father planted. In early February, select the paternal father to sow the father in the reserved paternity. After seedling emergence, 4 to 5 true leaves, the seedlings will be planted at a spacing of 10 cm. After the strains twitched, they removed the greenhouse film around April 15th. In order to increase the seed production, 1 to 2 boxes of bees are set per mu.
4. Water and fertilizer management. In the initial stage of straining, 15 kg of urea was harvested per mu, which promoted more branches for seeding. In the early stage of flowering, the compound fertilizer (nitrogen, phosphorus, potassium, 15% each) of 20-30kg per mu can be used to promote flowering elongation and bud development. During the flowering period, adequate supply of water and fertilizer is required to ensure the robust growth of the plants. After entering the pod period, the number of watering operations was appropriately reduced, the pods began to turn yellow, watering was stopped, the seeds were matured, and the kernels were full and full.
5. Pest control. The pests that are harmful to radish strains are mainly aphids, diamondback moths and leaf miners, and the disease is mainly downy mildew. Control locusts, can be sprayed 3% acetamiprid EC 1500 times or 10% imidacloprid wettable powder 1500 times or 50% anti-inferiority WP 2000 times. Plutella xylostella larvae can be used to dilute 10% (fenprolonitrile) suspension agent 1200 to 1500 times, or 5% chlordeca (chlorfluazuron) EC 2000 times. The leaf miner flies with 2.8% avermectin EC 2500-3000 times spray. In late April, downy mildew began to occur, which can be sprayed with 72.2% Preclosure 600 times liquid and 72% Kelu wettable powder 500-750 times.
6. Strictly remove impurities. Before the flowering of the radish, the isolated area was inspected, and all the radish-retaining strains in the range of 1500-2000 m were completely removed. After flowering, the flowering period should be strictly avoided. The paternal generation is a high-generation inbred line. The hybrid plants can be distinguished based on their growth, height, branching habits, and petal color, and they can be removed in time. After the father has given flowers, he must remove the parent plants in time to prevent the male seeds from mixing and affect the purity of the hybrids.
7. Harvest timely. When more than 80% of the species are yellow, they can be harvested, usually on a sunny morning. The harvested branches should be promptly dried, sun dried and dried, and the seeds should be threshed when dried at 2 or 3 o'clock in the afternoon. Do not thresh without drying. After threshing promptly dried, selected storage.
