After the autumn day lily is harvested, timely field management can lay the foundation for a high yield in the coming year. The main points of management are:
Treatment of dead leaves and stalks By the end of August, the day lilies from all over the country should be harvested, and the day lily stalks will slowly wither. The dead leaves and stalks can be pulled out and burned with firewood. If you don’t have enough manpower, you can burn the stems and leaves directly in the vegetable field after they are dried, so you don’t have to worry about burning the seedlings.
Deep digging and turning the soil Deep ploughing and turning the soil in autumn can deepen and mature the tillage layer, enhance soil permeability and improve soil fertility. Deep ploughing should be carried out after the buds are harvested, early rather than late.
Choose to dig when the soil is dry on a sunny day, with a depth of 25-30 cm. Cut off the shrunken and senescent root system and promote the growth of new roots in autumn seedlings. For day lilies planted within 3 years, only dig 15-20 cm deep between the rows to prevent root damage to the seedlings.
Take care of autumn seedlings Daylily Seedlings germinate in October, which is the second growth of the year. Through autumn seedling growth and nutrient accumulation, to promote the formation of tiller buds, and lay the foundation for the growth of spring buds in the coming year.
Combined with deep plowing of the soil, 7.5-10 kilograms of urea, 25-30 kilograms of superphosphate and 150 kilograms of water per acre can be applied. After fertilization, cover 3 to 5 cm thick fine soil to avoid loss of fertilizer.
Prevention and control of pests and diseases Daylily is prone to damage from red spiders, cutworms and rust in autumn. Red spiders and cutworms can be controlled with 1000 times dimethoate or 500 times phoxim, 75 kilograms of liquid medicine per acre, spray once every 10 days. For rust, you can use 500-1000 times solution of Fenmeining for 2 to 3 times, once every 10-15 days, and use 50-75 kg of liquid per mu each time.
