The cultivation techniques of tuberose

The evening primrose is a kind of semi-wild vegetable, which is a kind of perennial herbaceous cane and is distributed in Yunnan, Guangxi, Guangdong and Taiwan. It is a kind of semi-wild vegetable that is eaten with fresh flowers and buds. With the effect of Liver and eyesight, it can treat redness and swelling, measles on the eye, corneal detumescence and so on. I. Characteristics: The root system of tuberose is more developed and more lateral roots are present. Stem unripe, without tendrils, leaves simple leaves, opposite, long oval to broadly ovate, green. Cymes, pale yellow-green flowers. The fruit is a capsule, lanceolate and acuminate. Seeds broadly ovate, with white tan hairs at top. The primroses grow in woodlands or bushes. Warm, moist, sunny, well-ventilated, loose and fertile soil environment, drought tolerant, tolerant, impatient, cold-tolerant, stop growing after falling leaves in winter; after spring, branches grow long leaves, each section has axillary buds or flower buds, With the continuous development of lateral branches and aspiration of inflorescences, flowering gradually occurs from May to October. The flowers smell fragrant and they are more fragrant at night. Winter results. Second, the cultivation techniques 1, breeding methods. Cuttings, layering, ramets or seedlings can be used. The use of cutting propagation, in the winter and spring, select semi-lignified, vigorously growing stem vines, cutting vines with a length of about 30 cm with three to five sections of cuttings for seedlings or planted directly in the field. Breeding only applies to plants with more collaterals near the base of the ground. The results of night primroses are few and generally do not breed with seeds. 2, planting, management and harvesting. Planted in spring and summer, choose well-drained plots, and apply basal fertilizer from a high sorghum, with a height of 30 cm, a long distance of 1-1.5 m, and a spacing of 50-70 cm. Open a hole in the pupa and place the seedlings obliquely in the burrow. Cover the soil and expose the seedlings to the ground. Cover the surface with a dry weed and water. Keep the soil moist afterwards. When the seedlings reach a height of 1 meter, they are erected and introduced. The method of arranging is similar to that of melons, beans, and the like. When the vines are introduced, 2-3 pieces of the main vines are left, and the excess is removed. When 40-50% of the florets contain medlars, the entire inflorescence is picked when a few flowers are open. Generally picked once a day, the flowers have been removed to remove, so as not to affect other buds, loss of commodity value. The daily yield of gladiolus is generally 1200-1800 kg per mu. 3, fertilization. After the garden is cleared in early March each year, the fertilizer is applied one time, 25 kg of compound fertilizer is applied per mu, and 200-300 kg of organic fertilizer (earth-fertilizer or farmyard fertilizer) is used to cover fertilizer. After every 20-30 days per acre drench Application of 15 kg of fertilizer solution or 500 kg of farmyard manure, soil cover fertilizer, do not apply partial nitrogen fertilizer. 4. Pest control. At present, the pests that are harmful to night primrose are mainly fleas and shells, and the disease has wilt disease. Anti-caries can be used to combat antimony 25% EC 800 times, 73% Kotel 2000 times and so on. For control of scale insects, use 40% Leko cream 600-800 times. Fusarium wilt resistance can be used as 600-800 times liquid with wilting and 600 times as 50% carbendazim. If a wilt disease plant is found, it should be promptly removed, brought out of the park and burned, and the soil around the diseased plants should be sprinkled with lime and replanted after one month.
