Day lily, also known as day lily, also known as forgetful grass and healthy brain, 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. Daylily is a perennial crop. It needs to be replanted after a certain period of time after planting. Therefore, it is very important to apply the base fertilizer before planting. If the bottom fertilizer is insufficient when planting the day lily, the planting will be delayed after planting and the yield will be low. Some high-yield experience is to open a 30-cm deep planting ditch before the daylily planting, 1000-1500 kg of perishable pigs and cow dung per 667 square meters, high-quality pond mud, field mud or compost 2000-3000 kg, calcium and magnesium More than 50 kilograms of phosphate fertilizer, layered into the planting ditch, after which the original surface layer of mature soil is laid. When planting, 667-2000 kilograms of high-quality fat ash should be applied for every 667 square meters. After planting, it will be used for every 667 square meters. Excreta 100-200 kg (diluted to water), or pig urinary water 750-1000 kg dripping, as a crush fertilizer. In this way, the upper, middle and lower layers have fertilizers on the layers, and after the livelihood of the daylilies, the fertilizer nutrients can be continuously supplied, laying a good foundation for the harvest and stable production. Keep in mind that all organic fertilizers must be decomposed, preferably solved by Golden Baby starter, which can sterilize, disinfect and remove eggs, thus achieving the goal of disease prevention and pest control.
Second, the harvesting fertilizer is based on the different growth and development stages of daylily, pleading for early application of seedling fertilizer, re-application of manure and supplementation 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, to promote the early growth of the leaves, to make the leaves grow stronger, and to have a strong assimilation area, laying a material foundation for the quantity and quality of the flower buds and flower buds. Spring seedlings should be applied early, usually at the beginning of germination. Spring seedling fertilizer can usually be applied with quick-acting nitrogen, phosphorus and potassium fertilizers. The dosage should be determined according to the application amount of winter fertilizer and soil fertility. Usually 100-200 kilograms of manure per 667 square meters, or 10 kilograms of calcium phosphate, combined with potassium sulfate or potassium chloride 5-10 kilograms.
2, fat fertilizer. According to the growth and development rules of flower yellow vegetables, in order to better exert the fertilizer efficiency, it is usually 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 mixed fermentation to promote the development of flower buds and flower buds. Two fertilizers per 667 square meters total: urea 12. 5-15 kg, superphosphate 10-15 kg, potassium sulfate or potassium chloride 10-12 kg. The first dose should be slightly less than the second time; in the second fertilization, the day lily is entering the reproductive growth period, requiring a large amount of fertilizer, the advantages of vegetative growth in subordinate status, the leaf age index has reached 100%, leaf tissue Enriched and able to be reapplied.
3, bud fertilizer. Lei fertilizer is a make-up method 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 picks all the seeds. It takes a lot of nutrients. Leifei is to make up for the nutrition of daylily, avoid premature aging of the fattening, maintain the greenness of the leaves, to achieve the buds and buds, increase the rate of buds, extend the harvesting period, and thus increase the yield of daylily. Shi Lei's time, usually after 10 days of picking, is about to enter the prosperous period and move forward. Urea 5-12. 5 kg per 667 square meters, drenched with water to apply the rhizosphere. In addition, multiple root fertilization and spraying of plant hormones can be performed during all buds. That is, using 0. 5% - 1% of urea, adding 2% of superphosphate (filtered by immersion), adding 0.2% to 0.3% of a mixed solution of potassium chloride, or using 0.1% Potassium dihydrogen phosphate.
Third, the application of biological fertilizer. The biological bacterial fertilizer not only contains a large number of nitrogen-fixing, phosphorus-dissolving and potassium-dissolving active bacteria, but also contains organic matter, humic acid and trace elements, and can be applied in combination with other fertilizers in any fertilizer season of Chinese cabbage. High-quality bacterial fertilizers, such as Golden Baby Fertilizer, can not only save the amount of fertilizer used, but also solve problems such as soil compaction and growth of soil microbial content.
