(1) The adventitious roots of the stem and nodule of the nursery shall be propagated in the stem and nodule of the purple flowering vegetables, and the plants may also be propagated in different plants. Generally, the propagation of the ramets is carried out before the plants enter into dormancy or resume growth, but the propagation coefficient of the ramets breeding is low, after the ramets. The growth of the plants is weak, so they are commonly used for cutting propagation. Take the tender stems from the strong mother plant for cuttings, each cutting length is about 10 cm, 3 to 5 leaves, excise the base 1 to 2 leaves, inserted in the seedbed, cuttings should be inserted obliquely, in order to facilitate rooting. Soil or fine sand can be used as a seedbed. The spacing of the cuttings is 6 to 10 centimeters. About 2/3 of the soil is buried. Regular watering is performed to cover the shading nets and moisturize. It takes about 10 to 15 days to survive. Cuts can be made throughout the year, making it easy to take root in spring and fall. After you survive, you can transplant with soil. It is also possible to insert the cuttings directly in the cultivation field. 2. Planting cultivated purple leeks, should choose good drainage, rich in organic matter, strong ability to retain water and fertility, good ventilation, slightly acidic loam, apply mature organic fertilizer as a basal fertilizer, deep-turning, Fuping, made of sorghum. Plant spacing is 25-30 cm 30 cm, planting 55-6000 per acre. Planting density depends on fertility, fertility is thin, dense and dense. Watering in time after planting. 3. Field management Purple radish is resistant to drought and waterlogging. Supply of appropriate moisture and fertilizers ensures high yields and quality. The principle of irrigation is that the soil is dry and wet. In the rainy season, attention should be paid to the prevention of drainage and flooding. After the start of harvesting, one fertilizer is topdressed for each harvest, and 500 kilos of manure and urea per mu, or 7 to 10 kg of urea, are used. 4. If harvesting is suitable for the season, it can be harvested 25 to 30 days after planting. The young shoots with a length of 10 to 15 cm and 5 to 6 leaves are generally taken as a product. The first harvest leaves 2 or 3 leaves at the base, and then grows new shoots from the leafhopper. When harvesting, leaves 1 to 2 leaves at the base, which can be harvested every 15 to 20 days in the warm season. Up to 500 kilograms.
