1. Seedlings: When harvesting buds, the seedlings are field-examined, no pests and diseases, and fields with high land purity are used as the breeding targets of the plants. When digging up the ramets and seedlings, the soil should be shaken off, and the old roots of the lower part of the rhizomes that have grown two to three years ago should be divided into one detached or every 2-4 shoots as a bundle. , Decay roots and cut off the roots, only keep 1 to 2 new roots, and cut the roots, leaving about 10 cm long.
Second, the application of basal fertilizer: lily field requires deep plowing more than 35 cm before transplanting, the soil broken, leveling. Lily is a perennial plant. Before planting, it is necessary to apply base fertilizer. It is best to open a 30-cm-depth planting trench before planting, apply the livestock and poultry fertilizer along the ditch, and then apply the surface layer of mature soil, and then apply high-quality fertilizer when planting. Spraying a new high fat film after planting can effectively prevent the ground water from evaporating, the seedling body water from transpiration, isolating pests and diseases, shortening the seedling period, quickly adapting to the new environment, and growing healthily.
Third, growth management: 1 reasonable irrigation and drainage. In spring, it is necessary to timely clear the ditch drainage of the cauliflower field to prevent waterlogging. During the high-temperature and dry season in July and August, we must divert water and drought in time to keep the soil moist and extend the harvest time so as to increase the yield. Drainage and irrigation should be carried out sooner or later, so that emergency irrigation can be done in a row, flood irrigation can not be applied, new high fat film can be sprayed, and water absorption amount can be adjusted. The timely spraying of Zhuang stalk can make the stem thick and thick, the leaves hypertrophy, the fresh leaves color and the plants flourishing.
2 fertilization. Day lily is very fertile and fat-tolerant, especially for nitrogen, phosphorus and potassium. Seedling fertilizer: A small amount of fertilizer is applied to spring seedlings to promote the healthy growth of young seedlings. Fertilizer: Combine cultivating fertilization 7 to 10 days before convulsions to promote convulsions that are neat and stout. Bao Lei Fei: In the early stages of convulsions, in order to enhance the drought resistance and disease resistance of plants, prolong the function of leaves, promote buds thick, reduce the loss of young buds, increase yield, should be applied for foliar fertilizer, timely spraying flowers Zhuang Ti Ling, can promote flower buds Strong, petal hypertrophy, colorful flowers, floral rich, prolonged flowering.
