Daylily is a common vegetable in summer. As people learn more about it, its sales volume continues to increase. The cultivation of daylily is relatively simple, but various problems will inevitably occur during planting. The following small series will give you a detailed view of the field management techniques of daylily. Let's take a look.

1. Seedling management
The seedling stage refers to the period when the new seedlings or the fixed seedlings are unearthed until the flower buds begin to appear, which belongs to the vegetative growth stage of the daylily. At this time, the seedling stage is in a dry and rainy season, watering should be timely, to ensure that the soil water content is between 60% and 70%, the watering should be poured, and the soil should be re-casted a second time when the soil is dry. The seedling period of daylily is relatively short, about 40 days. Fertilization should be as early as possible. It can be applied by acupoint application or ditch application. 25-40 kg of compound fertilizer is applied per acre. Fertilizer and water management in seedling stage is combined with cultivating and weeding. About 10 cm, when the weeding is not suitable for the seedlings too close, so as not to hurt the seedlings, generally need to cultivate and weed 1-2 times.

2, convulsion period
Day lily is more sensitive to water during the convulsion period. If there is water shortage, it will delay the convulsion, or even convulsion, affecting the feed of the flower buds, and the development of the head, thus affecting the yield of daylily. At this time, it should be fully watered to make the soil moist. Generally, it is once a week, and the nutrients needed for the daytime of the daylily are also relatively large. Therefore, it is necessary to apply top dressing at this time. Generally, the flower buds are extracted and the flower buds are started. Fertilization, mainly based on quick-acting fertilizer, combined with watering to improve fertility utilization.

3, flower bud period
The flower bud period refers to the period from the flower buds to the flower buds until the end of the harvesting. Generally, it is in the period of June-September of the year. This is the high-temperature rainy season. Therefore, the watering should be based on the rain conditions, and it is better to keep the soil moist. In case of continuous rainy weather, it is necessary to drain in time to reduce pests and buds, apply fertilizer once every 5-10 days, and apply about 45 kg of high-concentration compound fertilizer per acre.

4. Pest control
Day lily disease mainly includes leaf spot, leaf blight and rust, all of which are fungal diseases, generally occurring in August-September. Leaf spot disease can be controlled by Bordeaux mixture and detoxification, and sprayed once every 7-8 days. 2-3 times in a row; leaf blight can be sprayed with thiophanate-methyl, sprayed every 10-15 days for 2-3 times; rust can be controlled by enemy de-emulsion, sprayed every half month or so. Second, even spray 2 to 3 times. Insect pests mainly include red spiders and aphids. Aphids can be controlled with dimethoate emulsions once a week until the first half of the harvest. Drug red spiders can also be treated with dimethoate emulsion once a week, and the drug is stopped 10 days before harvesting. .
