The use of roots to propagate ranunculus, whether it succeeds or not and how to appreciate its beautiful flowers depends on whether or not it can be harvested and stored in a hot, hot and humid summer. Here are the breakdowns as follows: Root harvesting 1. Pre-harvest management The roots of ranunculus have become embryonic before and after flower bud differentiation, but the growth is increased after flowering. If no flowers are left at this time, the remaining flowers should be cut off and the buds removed. Timely watering, topdressing one or two times of liquid fertilizer with phosphorus, potassium as the main, so that ranunculus grow robust, and produce more nutrients to the underground roots, promote its increase, development and enrichment. Spray pesticides in time to prevent the damage of Liriomyza. 2. Timely harvest When the flowers and stems and leaves are completely yellow, nutrition all accumulates to the roots, timely harvest, avoid too early or too late. Early harvesting, lack of nutrients in the tuber, insufficient development, weak resistance to disease during storage, easy to be infected by bacteria and decay, late harvest, high temperature and rainy summer, high air humidity, high soil moisture content, root tuber Perishable in the soil. It is best to choose dry sunny excavation that lasts 2 to 3 days. To avoid bruising the roots, carefully dig them carefully. 3. The post-harvest treatment of the roots of the harvest should remove dirt and other debris, cut off parts of the dead leaves and dead trees, remove diseased roots. After grading according to size, rinse with water, put in 50% Carbendazim WP 800 times solution for 2 to 3 minutes, disinfect and sterilize. Then remove and spread out in a well-ventilated place without direct sunlight. Stalls should be thin to facilitate heat dissipation and moisture evaporation to prevent root heat from heating up and damaging buds or mildew. The roots stored after the roots are treated to dry the water and stored in time. If piled casually, without any protection measures, the dormant roots are vulnerable to pests or high temperature and humidity and other adverse conditions and become moldy rot deterioration. Common storage methods are: 1. Ventilation dry method will be ranunculus root tuber Packed in containers such as bamboo baskets, perforated cartons, and wooden boxes, containing waterproof paper or underlayment, with a thickness not exceeding 20 cm, stored in a ventilated, dry, cool, and sheltered place, or packed into bags, paper bags, plastics In a woven bag, hang it in a ventilated, dry place at room temperature. 2. Laminated sand method Select indoor ventilated and dry place. Use a dry sand with no impurities to lay a 10 cm thick cushion, lay a layer of roots, and then lay a layer of 5 cm thick dry sand. Such a layer of sand and a layer of roots, repeated accumulation of 3 to 5 layers, piled up into a cone, so that the root of ranunculus are evenly buried in fine sand storage. 3. potted soil method Potted plants can be preserved in the original basin soil in the summer, cut stems and leaves dead on the ground, after pouring again 0.3% potassium permanganate solution, no watering and fertilization, so that basin soil Keep dry. Keep the pots in a cool, sheltered and ventilated place until the autumn harvest and replant. Store the roots of ranunculus, tools and places must be disinfected, storage environment should be dry and cool. On cloudy and rainy days, it is necessary to strengthen ventilation and ventilation to disperse water. During storage, regular inspections should be conducted to eliminate individuals that have become mildewy or rotten from infective pathogens. The adjacent contaminated roots should also be removed and disinfected and dried with fungicides. After re-storage to prevent infection.
