Day lily (also known as day lily) has strong adaptability, and can be planted on the soil of glutinous soil, sandy soil and earthworms all year round. In order to obtain high yields of day lily, the following points should be grasped in cultivation management.
First, timely planting. From late October to early November, the climate is suitable, the light is weak, the survival rate of plants is high, and planting is the best.
Second, select planted varieties. The Mayflower, a medium-early-maturing variety with high yield, good quality, and strong resistance, can also be paired with a small number of late-maturing varieties such as Jingzhou flowers, long-mouthed flowers, and fine-leaved flowers.
Third, fertilization tillage. The lily is a perennial crop that is replanted 10-15 years after planting. Therefore, the application of base fertilizer after planting is particularly important, generally require 667 square meters of high-quality soil fertilizer 5000 kg, potassium sulfate 20-25 kg, and deep tillage, depth 30-35 cm. When planting, such as soil moisture is poor, pay attention to watering ostrich, 667 square meters and then applied 12 kg of ammonium phosphate, potassium sulfate 6 kg or 667 square meters of rot cooked cake fertilizer 55 kg, applied to the planting ditch.
Fourth, planting methods. 1 large and small rows of plants, 115 centimeters wide row spacing, 82 centimeters small row, about 45 centimeters in diameter, 667 square meters planted about 1500 clusters. Four seedlings were planted in the four corners of each hole, and the spacing was 15-20 cm. 2 and other rows of cluster planting, spacing 92 cm, 45-50 cm from the hole, 667 square meters planted 1400-1600. Each hole is planted with the same size and rows of plants.
Fifth, seedling treatment. 1 Pruning seedlings: The upper and lower parts of the seedlings should be trimmed, and the black pedicles in the lower part of the stems should be removed. Cut the root of the enlarged spindle on the fleshy root to 5-7 cm and remove the decaying root. Shorten 6-7 cm of the upper leaves of the shortened stem and remove the leaves. 2 Pharmaceutic immersion seedlings: Put the pruned seedlings into 50% thiophanate-methyl WP 1000 times solution or 40% carbendazim suspension 800 times solution and incubate for 10 minutes. Remove and dry immediately. Planting. When the seedlings are planted, they should be planted separately according to the classification of large, medium and small varieties and seedlings. This will not only improve the uniformity of the field, but also facilitate field management and promote the balance of the seedlings.
Six, planting depth. Generally suitable for 10-12 cm, sandy loam can be appropriate deeper, clay loam can be appropriate shallow, the general requirements of the top of the short stem should be planted into the soil 2-3 cm, 4-5 cm seedlings exposed height is appropriate.
Seven, field management. After 2-3 years of planting, the soil should be well-rooted every year, and soil and water should be carefully treated. It is also important to pay attention to soil cultivation, and to pay attention to top-dressing buds, fertilizers, fertilizers, and leaves. Shallow cultivator before spring emergence, topdressing urea 10-15 kg per 667 square meters, and watering, in order to promote the early spring and thick seedlings, called phytoplankton fertilizer. Slightly cultivating the row of scapes before planting, applying 15 kg of compound fertilizer per 667 square meters, prompting the thick branches of twitches to appear as early as buds, which is called cultivating yam. During the harvest period, 1/15 hectares of compound fertilizer 18 kg can reduce the loss of multiple buds and extend the picking period, which is called increasing budding fertilizer. The convulsions and blooming of hay can cause drop buds to reduce production, and should be timely irrigation to increase production. For every 7-10 days in the spring, 1 water is needed to keep the soil dry and wet. Spraying 20 mg/l of 2.4-D. or 400 mg of ferric molybdate during flowering can prevent budding. Collect 1 water every 3-5 days during the harvest period to keep the soil moist.
Eight, timely harvest. When buds are harvested too early, not only the yield is reduced, but also the color is black after processing, affecting the appearance quality of dried products. From the time the flower buds are removed to the time before processing, it continues to grow. Excessive buds may open gradually at this time, opening too many buds and reducing the quality of dried products. Therefore, picking should not be too late. It is generally appropriate to pick 1-2 hours before starting flowering. When picking, should be light and meticulous, with flower pedicle, without stems, no damage to flowers, do not injure the young buds, followed by sequential harvest.
Nine, promote winter seedlings. From autumn to winter, the lily garden will sprout green winter seedlings. The more vigorous the winter seedlings grow, the more organic nutrients they produce and accumulate, and the next winter seedlings will grow faster and stronger. In order to promote the winter seedlings, winter seedlings should be reused when the winter seedlings just germinate, and 250-350 kg of human waste or dripping with 8-10 kg of urea per 667 square meters.
Ten, Qingyuan disease prevention. Qingyuan disinfection can reduce the disease in the coming year. The method is: All the weeds, defoliation, and diseased plants in and around the field of lily flowers are concentrated and burned; spraying 25-60 times of lime sulfur mixture, or spraying 667 square meters of day lily ground, 25-40 kg of quick lime, Earthworms and soil disinfection have a good effect. In the early stage of autumn, insist on spraying 0.5% dichlorine plus 0.1% detergent powder or 0.5 Baume degree lime sulfur 2-3 times every 7-10 days to kill overwintering bacteria spores and red spiders and other pests. Overwintering pest base.
