Day lily high yield fertilization method
Day lily, also known as day lily, is a perennial rooting plant. Because it is rich in nutrients and has medicinal value, it is increasingly welcomed by consumers. In addition to the continuous expansion of the domestic market, the foreign market has also been continuously developed. Due to the good benefits of planting daylily, and the longer beneficiary time, more and more farmers are planted and the area is gradually expanded. However, the same cultivation of daylily produces a large difference in yield. This is in addition to the selection of varieties and other factors, the fertilization level is different. It is also an important reason. Different fertilization methods should be adopted according to the differences of new seedlings, old seedlings and conventional seedlings. Difference in seedling age, staged fertilization, first, new planting seedlings can be planted well, 30-50 cm in width, 20-25 cm in depth, and basal fertilization is applied in the cave; second, 15 years old young plants are planted due to aging. Flower buds are thin, buds are young and small, need to be updated, and old and weak seedlings are used to make up organic fertilizers. Third, conventional seedlings should be applied well to spring seedlings, stipends, and autumn fats. Scientific formula, balanced fertilization In order to grow lily vigorously and prevent the invasion of diseases, we must pay attention to scientific formula and balance fertilization. The first is the use of organic fertilizers such as human waste, urine, compost; the second is the purification of active organic compound fertilizers such as Huimanfeng, Diledan, etc.; the third is high-energy organic compound fertilizer; and the fourth is inorganic NPK fertilizer. The first three kinds of fertilizers are mainly used as base fertilizers and spring seedlings; at the same time, inorganic fertilizers are applied. Spring seedlings with 10 kg of nitrogen fertilizer and 7 kg of potassium fertilizer; 10-15 kg of chemical fertilizer per acre with moss fertilizer; Autumn fertilizer is recommended to use human excreta, 500-750 kg per mu, and the appropriate amount of phosphorus and potassium fertilizer. At the same time, root shooter fertilizer should also be applied 10 days after harvesting. The cultivator sparsely soil, the stable period of the water diverting day lily is as long as 15 years. After harvesting or after heavy rain, the lines are easy to compact, especially in the soil where the soil is relatively barren, and the yellow flower is affected. absorb. Therefore, during the fertility period of yellow flower, it is necessary to diligently work on cultivating loose soil. Before emerging from flower buds, it should be smashed three or four times. After the buds are harvested, they should be intensively cultivated to create a loose environment and improve the ability to retain fertilizer and water; It is necessary to combine cultivating fertilization and reduce the loss of fertilizers. Thirdly, in the event of drought, timely watering, so as to adjust fertilizer with water and increase the capacity of fertilizer supply.
