First, planting fertilizer. Lily is a perennial crop, and it takes a certain number of years before planting to replant. Therefore, it is very important to apply base fertilizer before planting. If the base fertilizer is insufficient when planting day lily, the production will be delayed after the planting and the yield will be low. Some of the high-yielding experience is to plant 30 cm deep planting trenches before planting day lily, apply 1,000-1,500 kilograms of fermented pigs, cow dung per 667 m2, quality pond mud, field mud or compost 2000-3000 kg, calcium and magnesium. Phosphorus fertilizer more than 50 kilograms, layered into the planting ditch, and then lay the original surface layer of mature soil, when planting, every 667 square meters but also apply high-quality fertilizer ash 1500-2000 kg, after planting, immediately after every 667 square meters Fecal urine 100-200 kg (diluted to water), or 750-1000 kg of pig urine dripping, as a pressure manure. In this way, there are fertilizers on the upper, middle and lower layers, and after the livelihood of day lily, it is possible to ensure the continuous supply of fertilizer nutrients, and to lay a good foundation for the stable production of high yields. Note that where organic fertilizers must be decomposed, it is best to treat them with the Kimpo Fermenter, which can sterilize, disinfect, and remove eggs, so as to achieve the purpose of preventing and controlling insects.
Second, harvesting fertilizer According to the different growth and development stages of lily, require early application of Miaofei, reapply manure, make-up bud fertilizer.
1, Miao Fei. After day lily has emerged in mid-February, it is the seedling stage before the buds are sown. The nutrients supplied at this time are mainly used for emergence and long leaves, which promote the early growth of leaves, make the leaves grow robustly, have a strong assimilation area, and lay the material foundation for fighting for the quantity and quality of flower buds and bud differentiation. Spring seedlings are applied earlier, and should generally be carried out at the beginning of germination. Spring seedlings can generally be used in combination with available nitrogen, phosphorus, and potassium fertilizers. The dosage should be based on the amount of winter fertilizer and the soil fertility. In general, 100-200 kilograms of human waste is applied per 667 square meters, or 10 kilograms of calcium phosphate is applied, and 5-10 kilograms of potassium sulfate or potassium chloride is used.
2, Feifei. According to the law of growth and development of yellow flower, in order to better exert the fertilizer effect, the fertilizer should generally be applied once when the calyx began to differentiate and when the calyx began to be extracted. For the first time, it is best to use human urine and cake fertilizer after mixed fermentation to promote the development of flower buds and buds. The total fertilizer used per 667 square meters 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; the second fertilization, lily is entering the reproductive growth period, requires a large amount of fertilizer, vegetative growth in a subordinate position, leaf age index has reached 100%, leaf tissue enrichment Can be repeated.
3, Lei Fei. Fertilizer is a supplementary measure and has a certain effect on the increase of production. Day lily has the characteristics of continuous picking and germination, long picking time, and the entire picking period requires the consumption of large amounts of nutrients. The bud fertilizer is to supplement the nutrition of day lily, prevent premature aging of defertilizer and keep the leaves green, so as to reach the buds of buds, increase the rate of bud formation, extend the picking period, and thus increase the production of day lily. Shi Lei Fei's time is generally 10 days after the start of picking. Per 667 square meters with urea 5-12.5 kilograms, drenching water application Shi Gen. In addition, multiple root explants can be applied and sprayed with plant hormones throughout the harvest. That is, use 0.5%-1% urea, add 2% superphosphate (filtered by leaching), add a 0.2%-0.3% mixture of potassium chloride, or use 0.1% potassium dihydrogen phosphate.
Third, the application of biological bacterial fertilizer. Biological bacterial fertilizer not only contains a large number of nitrogen-fixing, phosphate-solubilizing, and potassium-releasing active bacteria, but also contains organic matter, humic acid, and trace elements, and can be applied in combination with other fertilizers in any fertilizer-demand period of Chinese cabbage. High-quality fungus fertilizers, such as Kumba fungus fertilizer, can not only save the amount of fertilizer used, but also can solve soil compaction, increase soil microbial content and other issues.
