Day lily, the day lily, has a long history of cultivation in China. It is a kind of flower treasure vegetable with high nutritional value and various health functions.
First, plant fertilizer. Day lily is a perennial crop. Before planting, it should be ditched and fertilized to open a 30-cm deep planting ditch. 1000-1500 kg of fermented pigs and cow dung per acre, 2000-3000 kg of high-quality compost, and 50 kg of calcium-magnesium phosphate. Layered into the planting ditch, and then laid the original surface layer of sap. Note that all organic fertilizers must be decomposed, preferably treated with formaldehyde, which can sterilize, disinfect and remove eggs, thus achieving the purpose of disease prevention and pest control.
Second, harvest fertilizer. According to the different growth and development stages of daylily, it is required to apply seedling fertilizer early, reapply the manure fertilizer, and supplement the application of bud fertilizer.
1, Miao Fei. After the emergence of day lily in mid-February, the stage before the flowering of the flower buds is the seedling stage. The nutrients supplied at this time are mainly used for emergence and long leaves, promoting the early rapid growth of leaves, making the leaves grow robust, with strong assimilation area, laying a material foundation for the quantity and quality of flower buds and flower buds. The application time of spring seedling fertilizer should be early, and should generally be carried out at the beginning of germination. Spring seedling fertilizer can generally be applied with quick-acting nitrogen, phosphorus and potassium fertilizers, and the dosage should be determined according to soil fertility. Generally, 100-200 kg of manure is applied per mu, or 10 kg of calcium phosphate is applied, and 5-10 kg of potassium sulfate or potassium chloride is added.
2, fat fertilizer. According to the law of growth and development of flower yellow vegetables, in order to better exert the fertilizer effect, it is generally necessary to apply fertilizer once when the flower buds start to differentiate and when the flower buds start to be extracted, so as to apply quick-acting fertilizer. For the first time, it is best to use human excrement and cake fertilizer to mix and ferment, to promote the development of flower buds and flower buds. Total fertilizer per mu twice: urea 12.5-15 kg, superphosphate 10-15 kg, potassium sulfate or potassium chloride 10-12.5 kg. The first dose should be slightly less than the second time; when the second fertilization, the day lily is entering the reproductive growth period, the fertilizer needs to be large, the vegetative growth is subordinate, the leaf age index has reached 100%, and the leaf tissue is enriched. Can be reapplied.
3, bud fertilizer. Lei fertilizer is a supplementary measure that plays a certain role in increasing production. Daylily has the characteristics of continuous picking and continuous germination. It takes a long time to pick and consumes a lot of nutrients during the whole picking period. The bud fertilizer is to supplement the nutrition of daylily, prevent premature aging of the fattening, keep the leaves green, to achieve the bud bud, improve the bud rate, extend the harvesting period, and thus increase the yield of day lily. Shi Lei's time is generally good after 10 days of picking, that is, it is about to enter the promising period. Use urea 5-12.5 kg per acre and apply water to the rhizosphere. In addition, multiple external fertilization and spraying of plant hormones can be performed during the entire bud release. Use 0.5%-1% urea, add 2% calcium superphosphate (filtered by dipping), add 0.2%-0.3% potassium chloride mixture, or 0.1% potassium dihydrogen phosphate.
