High-yield cultivation techniques of day lily

The lily is a perennial herb whose buds are nutritious and delicious. If timely picking, reasonable processing, it is a delicious food on the table. Now its high-yield cultivation and fresh-keeping processing technology is introduced as follows: Cultivation and management techniques 1. Site preparation of basal fertilizer. The day lily has a well-developed root system and a fast tiller. It requires relatively loose and deep soil. Before transplanting, it should be deep-turned about 30 centimeters, combined with 5000-10,000 kilograms of soil-fertilizer, 50-75 kilograms of superphosphate, or diammonium phosphate 50. Kilograms of potassium fertilizer 15-25 kg. After the ploughing, the soil will be ploughed and the fields will be leveled so that they will be able to achieve a virtual reality. Second, transplanting. Transplanting is divided into spring planting and autumn planting, but autumn planting is better. Autumn planting should be carried out in mid-September and spring planting is most appropriate in late March. Before planting, the ramets must be planted. Select a large number of buds, good quality, 15-20 births with more tillers, dig them up whole or in part, and then divide the roots of the tillers from the shortened stems, cut off the aged roots, and apply the roots properly. Short cuts can be transplanted as seedlings. Day lily grows for a long time. Generally, width and width should be used for cultivation. The width is 70 centimeters, the narrow line is 35 centimeters, and the distance between holes is 35 centimeters. It is appropriate to use triangle or planting method, and 3-4 plants per hole are appropriate. Pay attention to the depth when transplanting, generally 15-17 centimeters is better. If the depth is too deep, the delivery will be slow and the harvest period will be delayed; if it is too shallow, the seedlings will be weak and the yield will be low. Third, field management 1, cultivator: cultivator should be carried out three times a year. The first time after germination in the spring. The cultivator should be combined with topdressing to loosen the soil and transfer fertilizer to promote the vigorous growth of seedlings. The second time after the day lily was harvested, the loosening was mainly to remove weeds, loosen the soil and receive rainwater. The third time should be carried out after the cutting of the leaves, mainly in the soil, to ensure that the root system can safely pass winter. 2. Watering: Daylily is tolerant to drought, but water shortage is not allowed during flowering. Watering conditions can be watered 2-3 times during flowering. Lily seedlings are not tolerant and should be drained in time if there is heavy rain or water in the fields. 3, Bao Lei: Day lily often caused by lack of water and fertilizer or not timely and cause buds. In order to prevent budding, in addition to well-cultivated cultivators, fertilization and appropriate watering, the following measures can also be used: 1% of the 2,4-D stock solution is diluted 6000 times to fully spray the plants, or 3010 mg/kg of "BA" is used. Growth hormone was sprayed after the first flower was opened, and sprayed once every 7-8 days for a total of 2-3 sprays. 4. Cut the calyx and old leaves: After the buds have been harvested, cut the calyx and old leaves; in the autumn, the leaves will be cut off when the leaves are withered, and the leaves may also be cut in the spring next year. 5, the main disease of day lily leaves blight and leaf spot disease: the use of high dry terrain, well-drained plots, before the onset of spraying protection, such as 1:1:1000 times Bordeaux mixture, 500-600 times the 65% zeocin, spray once every 7-10 days, spray 2-3 times. The main pests are locusts, red spider mites and crickets; 50% anti-inflution WP can add water 40 kg spray can effectively control aphids; 50% phoxim EC 300 ml mixed fine sand 30 kg, with the cultivator into the soil, can Effectively kill underground cockroaches; lime sulfur can inhibit the spider mite damage. Fourth, picking. The daylily is budding one after another, and it gradually blossoms. Therefore, it must be harvested every day. Harvest time is 3-5 pm. When harvesting, the buds are required to be light yellow, the longitudinal grooves of the yellow petals are obvious, and the flower mouth is unbroken.
