High-yielding Cultivation Techniques of Day Lily
The lily plants of the genus Liliaceae have a high nutritional and medicinal value and are one of the major famous specialty products in the eastern Yunnan region. Day lily is easy to plant and has good longevity, high yield, and considerable economic income. The main high-yielding cultivation techniques are: 1. Deep-sloped soil preparation: Day lily has a hypertrophic fleshy root system, which requires loose soil conditions to ensure its robust growth. Before planting should be deep-turned more than 30cm, combined with deep-turning, Mushi roasted high-quality farmyard fertilizer 5000 kg, 50 kg of calcium, then squatting leveling. 2. Handle seedlings. First, the black pedicle in the lower layer of the shortened stem is cut off, and the root of the expanded heel of the fleshy root is cut, cut to 5-7 cm, and the decayed root is removed. Then, the upper leaves of the shortened stems were clipped 6 to 7 cm and the leaves were removed. Before planting, the well-prepared seedlings shall be soaked in an aqueous solution of one-thousandth of a 50% thiophanate-methyl humectant for 10 minutes, removed by drying, and left to be planted. 3. Timely planting. In addition to jujube seedling and picking period, daylilies can be planted at other times, especially planted in spring and autumn. Autumn planting should be carried out before the soil is frozen. Planting is generally better during the Mid-Autumn till late autumn, and the spring planting works well after the soil is thawed. 4. Reasonably dense planting. In order to make full use of space and facilitate picking and management, daylily should be planted in narrow and wide rows, generally 75cm in width, 60cm in narrow rows, 36 to 45cm in clusters, 1600 to 2000 bushes in acres, 3 in each bundle, and 10 rows in bundles. 12cm, 4800 ~ 6000 acres with seedlings. 5. Properly planted. The root group of day lily is produced from the short shortening stem, it has a layer of one year, from bottom to top, the root part of the hair is moved up year by year, so the appropriate deep planting will help the plant survive and prosper. The general planting depth is 10-15cm. 6. cultivator soil. The daylily is a fleshy root, and it is necessary to have fertile loose soil environment conditions before it is conducive to the growth and development of the root group. The cultivator has loose soil, enhances permeability, warms the soil, eliminates weeds, and promotes robust growth of plants. Cultivate 2 to 3 times during the growing period. For the first time when the seedlings were unearthed, the second time in the period of bolting combined with cultivator soil. 7. Pay attention to top dressing. Day lily requires the application of sufficient winter fertilizer, early application of Miaofei, re-application of a coating of fertilizer, and application of bud fertilizer. 1 spring Miao Fei. Miaofei is mainly used for emergence, long leaves, and promotes early growth of leaves. Seedlings should not be late as early as possible. They should be applied when the spring begins to sprout. Generally, they use 10 kg of superphosphate and 5 kg of potassium sulfate. 2 moss fertilizer. Dayling bolting period is an important period from vegetative growth to reproductive growth. This period requires more fertilizer, it should be applied when the flower moss begins to pull out, generally mu recovery urea 15kg, general calcium 10kg, potassium sulfate 5kg. 3 bud fat. Bud fertilizer can prevent deferred fat premature aging, improve the rate of budding, extend the picking period, increase production. Should start picking after 7 to 10 days or so, generally 5 acres of urea. At the same time, the spraying of 0.1% potassium dihydrogen phosphate aqueous solution once every 7 days or so on the picking period has obvious effects on the buds and preventing budding. 8. timely irrigation. Day lily is sensitive to moisture during the period of bolting and budding. Water shortage during this period will cause severe budding. It should be applied 2 to times according to the soil conditions to avoid production loss due to drought. 9. Control pests. The main pests and diseases of day lily were yellow spider mites and yellow aphids. Spraying with 40% of Leko cream from 1000 to 2000 times was effective. However, spraying should be stopped 10 days before picking. The common main diseases of day lily are rust. Leaf spot disease, leafy orange disease, yellow leaf disease, etc. In the early stage of disease, foliar application is controlled by using 50% thiophanate WP 800 to 1000 times or carbendazim 600 to 1000 times.
