Special white jade radish cultivation technology

Teixin Baiyuchun is a radish variety produced by Korea Bio Co., Ltd. and introduced by Beijing Shinong Seedlings Co., Ltd. The plant type and quality of this variety are different from those of Baiyuchun and Xinbaiyuchun, and they are the best among the meaty dense radish. Because of its wide adaptability, rapid growth, high yield, and good merchandise, it has been popularized in recent years.

1. Characteristics:

Leaves clusters open, medium growth, plant height 42 cm, plant width 70 cm. The leaves and leaves are bright green and glossy, with 21 leaves and 47 cm in length. The fleshy root is without neck, straight-shaped, 36 cm long, 7.8 cm in lateral diameter, fine lateral roots, shallow root hole, smooth and delicate appearance, white and white flesh, dense meat, sweet, delicious taste, single root weight 1.2-1.5 kg, maximum 4.6 kg. Medium growth period, 35 days after the spring, summer and autumn cultivation sowing began to enlarge the fleshy root, 52-80 days harvest, winter sowing spring harvest 90-140 days, 5000 kg per mu yield. Seeds are brown in color, with large grains and a weight of 15.77 kg.

This species is suitable for the growth temperature of 12-32 degrees Celsius, and can withstand high temperatures of 36 degrees Celsius for a short time in summer, but is susceptible to soft rot and virus diseases under high temperature conditions. In January, the average temperature above 6 degrees Celsius can be cultivated in winter. In July, the average temperature below 24 degrees Celsius can be cultivated in summer.

2. Cultivation points:

(1) Cultivation season. Spring broadcast from February to March, from mid-April to May. The altitude of 700-1000 meters of high mountains from April to August broadcast, 6-11 month collection.

(2) Cultivation grounds. In order to promote the main roots to be planted, the cultivated land is best cultivated with loose and fertile soil, and the deep soil layer is the best. The paddy field is used for the cultivation of large-groove, high-sorghum, and cover-film cultivation, and the paddy field is used to pulverize the soil blocks in a rotary plough. More than 30 centimeters; land that has been planted for more than two seasons in succession is prone to nutrient deficiency, and it is better not to use it. Glyphosate used to control weeds before planting should be carried out one month earlier, too late to produce phytotoxicity, control after cultivating can be sowed after the cover soil, spraying glyphosate and butachlor mixture.

(3) sowing. Winter and summer sowing should be dense, spring and autumn sowing slightly dilute. Generally even ditch 13 cm wide to broadcast 3 lines, spacing 25-30 cm, spacing 20-27 cm, seed sowing seeds 1-2 seeds per hole, leaving 1 seedling, 6000-8000 holes per acre sowing, with the amount of 100- 150 grams, after sowing, flood control, drought prevention, anti-rainstorm, promote germination and emergence, after emergence, pay attention to the prevention and control of seedling pests and diseases.

(4) Growth period management. Basal fertilizers were not used enough. They were topdressed 1-2 times during the seedling and early radish expansion. The whole process required 50 kg of calcium magnesium phosphate fertilizer, 25% nitrogen and potassium fertilizer 100 kg, potassium sulfate 10 kg, and appropriate amount of boron and molybdenum fertilizer. No de-fertilization can occur during growth. During the middle and late radish enlargement, the water should be supplied in a balanced manner, especially in the high-temperature period, the dry roots and storms are prone to cracking; the soil is too humid and can easily cause root rot or premature plant failure. Plant protection focuses on the prevention and treatment of spring and autumn fleas, summer soft rot, and autumn virus diseases. The prevention and control of pests such as Plutella xylostella, leaf miner, green worm and aphid should also be carried out as soon as possible.

(5) Harvesting. The outer leaves began to fall yellow, which is suitable for harvesting. At this time, the root type is white and well-distributed, and the commodity is good. In order to meet the market requirements, generally a single root weight control in the 0.7-1.3 kg, leaving fresh petiole 5-7 cm, clean, neat bagging, timely delivery and sales.
