Cylinder, pots of lotus flowers cultivation, humus-rich pond scum, etc. If a culture medium, generally do not need to be able to meet the growing base fertilizer plants normal growth, bud, flower, seed needs; If poor soil for substrate , you need to increase base fertilizer, with maturity cake, bone meal and other by a certain percentage Hunban with mud can be. Basin, tank cultivation of flowers like fat, but avoid heavy fat, particularly to prevent basal excessive, causing injury seedlings Simiao. If the basin (tank) of water, fat, green, bubbles emerge, and fist pumping raw lotus leaf wrinkling can not stretch, mostly caused by too much fertilizer. Once this happens, care should be dug as soon as possible kinds of lotus root, replace the soil re-planting. Water in the bud before and after, if the leaves appear chlorotic yellowing, pot (tank) you can use 3-4 grams of high-quality fertilizer, squeezed from the soil in the 3-4 point, and promote plant growth; If you are growing strong, thick leaves Green, late bud, but feel little real hard, you can separate P and K applied, appropriate amount of boron zinc.
(2) water management pond in the cultivation of ornamental flowers, seedlings 10-30 cm in shallow water to maintain appropriate. When the plants grow into the prosperous period, when higher temperatures increase the water level to play the role of water thermostat, generally 20-40 cm is appropriate. Water too deep, it will inhibit the formation of branching, reduced flower number.
Cylinder, potted Peihe flowers, water management is critical. General kinds of Lotus flowers cultivation, planted every one day after a good 2-3 cm deep water pouring in the money leaves grow, the water depth can be increased to 5 cm, while protecting the nascent leaf, remove moss and algae at any time, to improve soil temperature, water is conducive to Fourier elongation as soon as possible. With the Fourier pumping, the temperature rose, and gradually fill the basin water. When immediately grow 2-3 sheets, usually when the residual float put off the old, keeping pots of surface air and light. Hot season, watering 2-3 times a day, exercises to maintain deep water; even rain, but also pay attention to make water. Lotus once dehydration, leaf margin Kujiao soon change, resulting in lost bud, at least half of the conservation can be restored. Autumn plants grow slowly and gradually into the dormant period, keep a small amount of water to the basin, when the temperature dropped below 0 ℃, the basin surface layer of straw or straw mat sealed in order to facilitate the winter.
3. Pest management
(1) disease prevention and treatment of disease are more flowers, especially the hot season, the incidence is particularly high. One serious damage, the widespread occurrence of infectious disease of corruption, disease, leaf spot, brown grain disease, Septoria disease. Disease should be based on prevention, especially the agricultural control, such as the use of resistant varieties, rational crop rotation, organic manure, litter clean-up leaves, etc., is an effective means of reducing pests and diseases. Dorsch decomposition of organic fertilizer, increased phosphorus, potassium, silicon fertilizer, control of nitrogen fertilizer. Implementation of cropping to reduce pathogen accumulation.
① corruption, disease, brown grain disease, Septoria disease in the early stages, whole-plant spraying thiophanate-methyl, carbendazim 50% WP 600 times every 7 days, spray, and even spray 2-3 times with good effect.
② the early stages of anthrax, prevention and treatment with imidazole fungicides, such as: torch 1000-1500 times, even spray 2-3 times, you can effectively control the spread of disease.
(2) Pest Control timely, comprehensive, scientific prevention is an effective means of pest control lotus. The main pests are harmful lotus flowers: litura, leaf mosquito bite, the real cone snails and so on.
① litura Austrian Green No. 1 choice, or cutting edge efficiency and low toxicity pesticides such as 800 times the liquid spray pest control, requiring the lower leaves and spray the top leaves, every five days, spray, and even spray 3 times ; or black light trap and kill adults.
② leaf major hazards of mosquito bite leaves, seedlings, with 90% trichlorfon 1000 times foliar spraying to control pests.
