Health Food--Lily Cultivation Technology

In recent years, due to the unique flavor of flower foods and special health care functions, the demand for flower foods is growing. Fresh flowers and vegetables have become special vegetables. Lily is a typical example. Lily is a perennial plant of Liliaceae, and its underground bulbs contain a large amount of protein. It is an emerging health-care vegetable variety that is hot on the market. The market price is more than 20 yuan per kilogram, and the economic benefit is considerable. Lily has strong adaptability and can grow well in both the south and the north. The planting technology is easy to grasp and is suitable for the development of planters and parks. First, sowing lily does not require strict soil quality, but it is better to choose cool, dry, sunny conditions and well-drained sandy soil. Do not continue cropping in order to prevent the emergence of blight. The soil layer should be deep-turned over 20 cm and full of organic fertilizer should be applied. Lily cultivation is generally conducted from September to October, and full, full, and disease-free bulblets should be selected. Commercial bulbs can be harvested 1 year after planting. Before planting, bulbs can be soaked in a 2% formalin solution for 15 minutes, and then allowed to plant after being allowed to dry. Planting density spacing 25 cm, spacing 10 cm. After the bulbs are planted, they are filled with fine soil around them and the bulbs cover the bulbs. To keep the soil moist, cover it with straw. Second, after the emergence of cultivation and management to uncover the straw, trench fertilizer, fertilizer can not contact the bulb. Only one strongest bud is left after budding, and the remaining buds are removed to prevent the bulb from cracking. Lily needs more water during the growth period, it is advised to keep the soil moist, but not too moist, avoid water accumulation, and pay attention to drainage and flood prevention after the rain. During drought, irrigation is performed once every 5 to 7 days. It is advisable to use furrow irrigation to reduce soil compaction. Do not water during late growth and dormancy to avoid rot. Lily prefers a cool climate with a temperature suitable for growth of 10°C to 25°C. However, it is advisable to keep the temperature at a minimum of 13°C after planting until emergence. After emergence, raise the temperature appropriately and control it at about 22°C during the day. Northern open field cultivation can choose leeward sunny place, and winter use grass to cover and keep warm. In summer, when the ground is covered with grass and the temperature is high, the lilies will enjoy ample sunshine. The lack of light may cause the plants to grow long, but they should not be exposed to direct sunlight. If necessary, they may be properly shaded. Lily is a hi fat crop. Since the young seedling grows, the upper stem has begun to be top-dressed, the combination of earth application and foliar spray, 10 to 15 days top dressing, 1 thin fertilizer application, avoid heavy fertilizer, early stage Nitrogen fertilizer is the main fertilizer, and phosphorus and potassium fertilizers are the main fertilizers in the bud. When the height of seedlings is 20-25 cm, earth is used to protect exposed scales. When budding, it enters the expansion of bulbs. A 0.2% potassium dihydrogen phosphate and 0.1% urea mixture was sprayed on the foliar to prolong the life of functional leaves. When the height of the plant is about 50 cm, it suppresses the growth of stems and leaves and promotes bulb enlargement. During the period from June to July, the buds should be removed timely and the consumption of nutrients should be reduced. The prevention and control of pests and diseases of lilies is mainly prevention. The main diseases include blight and soft rot. The blight is controlled by spraying 75% chlorothalonil wettable powder 600 times, and 47% by Garrinone for soft rot. 800 times liquid powder spray control; pests are mainly fleas, can be used BT emulsion 500 times or 50% phoxim 1000 ~ 2000 times Irrigation root control. Third, the harvest is generally in the fall, when the above-ground parts are completely withered and the bulbs have been fully matured, select sunny harvesting. The newly excavated bulb must not be exposed to sunlight to prevent scales from losing water or discoloration. The average mu yield can reach more than 1000 kg.
