Day lily high-yield fertilization method

Day lily, also known as day lily, is a perennial plant. Because it is rich in nutrients and has medicinal value, it is more and more popular among consumers. At present, in addition to the continuous expansion of the domestic market, foreign markets have also been continuously developed. Because the benefits of planting daylily are better, the benefit time is longer, more and more farmers are planted, and the area is gradually enlarged. However, the same planting of daylily has a large difference in yield, which is different from the factors such as variety selection. It is also an important reason. Different fertilization methods should be used depending on the new planting, old seedlings and conventional seedlings.

Different age of seedlings, staged fertilization

First, the new planting seedlings can be opened first, the hole width is 30-50 cm, the depth is 20-25 cm, and the base fertilizer is applied in the hole; the second is the old seedling planted for more than 15 years. Because the plant is aging, the flower bud is thin and bud. Shaolei is small and needs to be renewed. After excavating the old and weak seedlings, the organic fertilizer is applied. Third, the conventional seedlings should be applied with spring seedling fertilizer, moisturizing fertilizer and autumn fertilizer.

Scientific formula, balanced fertilization

In order to make the daylily grow stronger and prevent disease invasion, it is necessary to pay attention to scientific formula and balance fertilization. First, use decomposed organic fertilizer such as human excrement, column manure, compost; second, refined active organic compound fertilizer, such as Hui Manfeng, Di Le Dan, etc.; third is high-energy organic compound fertilizer; fourth is inorganic nitrogen, phosphorus and potassium fertilizer. The first three kinds of fertilizers are mainly used as base fertilizer and spring seedling fertilizer; at the same time, inorganic fertilizer is applied. Spring seedlings are combined with 10 kg of nitrogen fertilizer and 7 kg of potassium fertilizer; the fertilizer is applied with 10-15 kg of fertilizer per acre; the autumn fertilizer advocates the application of human excrement, 500-750 kg per mu, and the appropriate amount of phosphorus and potassium fertilizer. At the same time, after 10 days of harvesting the flower buds, root spray fertilizer should also be carried out.

Cultivate soil and water

The stable harvest period of daylily is more than 15 years. After harvesting or after heavy rain, it is easy to tie the knot, especially the soil with poor soil is more likely to be knotted, which affects the absorption of fertilizer by yellow flowers. Therefore, during the growth period of yellow flowers, it is necessary to diligently cultivate the loose soil, and before the emergence of the flower to the flower buds, it should be shallow for 3 to 4 times. After the buds are harvested, they should be deeply ploughed to create a loose environment and improve the ability to retain fertilizer and water. It is necessary to combine fertilization with cultivating and reduce the loss of fertilizer. Third, in the case of drought, timely watering should be done to adjust fertilizer with water and improve fertility.
