The method of improved Variety cultivation of Lily

Lily is used as a bulb for food or medicine, which has the effect of moistening the lungs and relieving cough, clearing the heart and calming the mind; it is a kind of economic crop widely planted by farmers in recent years. In this paper, the cultivation methods and technical points of improved varieties of lily are introduced as follows: after lily harvest, select the large bulb with strong growth, no damage and no disease and insect harm, cut off the base, leave the scales and dry for several days. Open a horizontal trench at a row spacing of 15 cm on the whole seedbed, with a depth of about 7 cm, and then place a scale into the horizontal furrow every 3 cm (the top of the scale is up). After planting, cover the soil 3 cm thick, and cover the surface of the soil with a layer of straw. After the scales are planted, they take root and sprout in the same year, and the seedlings can grow in the next spring. After two years of cultivation, when the individual weight of the underground bulb reaches about 50 grams, it can become an improved variety of lily. Using the method of scale propagation requires about 150 kg of lily scales per mu. In the method of bulblet propagation, when the improved varieties are cultivated with bulbs, the suitable row spacing of the seedling bed is 24ml 26cm, and the furrow depth is 5ml 7cm. A bulb is placed every 5ml 7cm in the furrow of the seedling bed. The field management can be strengthened after emergence in the spring of the following year, and it can be harvested in autumn. During harvest, the improved varieties of lilies should be selected or retained according to the weight of the cultivated lily varieties, that is, those with an individual weight of more than 50 grams can be selected as improved varieties, and those with an individual weight of less than 50 grams can continue to be planted and cultivated. The seed propagation method collects the soon-to-mature lily capsules (the mature fruits of lilies) from September to October every year, and puts them in a ventilated and dry room for drying and ripening. Then use sand hiding method (build a burial pit with brick in the shady house or basement, spread 5mur7cm thick fine sand at the bottom of the pit, and then arrange the lily bulbs or fruits on the sand, which is covered with sand 3mur4cm, and so on, the stacking height should be 100cm). The seeds are screened out in the following spring, the row spacing of the seedling bed is 1015cm, and the furrow of the border is 3mur4cm. Sow the seeds into the box ditch, cover 2mur3cm of soil, and then cover the border with a layer of straw (to enhance the heat preservation efficiency of the border). After the seedlings are unearthed, the field management should be strengthened and the improved varieties of lilies can be obtained after three years of cultivation. In the method of bulblet propagation, the lily plant has bulbous buds in the axils of the leaves, and when the flowers fade in summer, the bulblets fall off by themselves, and then according to the conventional method of cultivating improved varieties of lilies, strengthen field management and reasonable application of fertilizer and water. can also cultivate improved varieties of lily.
