Lotus how to carry out maintenance management
Beijing Beihai Park Kang Lianping A: The author has summarized and answered three questions. 1. The long-term daily management of peanuts should pay attention to matters. Potted lotus plants in the Beijing area are usually planted in the early fall of April to mid-April. The first time the water is planted in dry soil, it must be thoroughly drenched. Then it can be dried for a few days and then watered in the basin. This can promote rooting. In the beginning, keep the basin soil moist. After 7 to 10 days, it can be watered from 1 cm to 2 cm deep. The floating leaves grow and the leaves are opened. As the temperature rises, the water level can be gradually deepened until it is full of pots.
Lotus joy, hi fat, like a good ventilation environment. Therefore, it is necessary to maintain sufficient light in its maintenance site, at least to maintain direct sunlight for 6 hours a day. Place the flower pots to pay attention to open spacing, the minimum pot spacing 20 cm, easy to air and light and vertical leaf growth.
Lotus fertilizer, in addition to the basic fertilizer applied at the time of planting, in the growing period to appropriate fertilizer. Generally, when the leaves grow, the buds are not used, and the top dressing is applied once. The compound fertilizer is the main ingredient, and the compound fertilizer, compound fertilizer or raw bean cake may be topped up. The depth of the soil is approximately 1/1. 2 places can also be applied directly. Observe its effect, generally effective after three days, pay attention to thin fertilizers, such as leaves, yellow or light green leaves, and thin, is the lack of fat, usually about 10 days after the topdressing. If the leaves are thick green and thick, it means that there is no shortage of fertilizer, and no application may be made. Generally, a maximum of three times in the growing season is applied. The amount of fertilizer is excessive, the pods are fragile, and the lotus leaves are dead.
2. How to prevent pests and diseases.
The common disease in the growing period of the lotus is brownish-brown disease, which is mainly harmful to the vertical leaves. It is caused by the infection of Alternaria solani, the other is spot blotch, and it also damages the vertical leaves. It is caused by the fungal spore spotting. The disease symptoms of the two disease burdens are very similar, and they are connected by patches to expand the plaque and make the mesophyll green and yellow. Most of them are concentrated in the onset of the rainy season, mainly due to high temperature, high humidity, weak lotus growth, and poor lighting conditions. In severe cases, it can be used for 800 times as much as dexamethasone or thiophanate solution. The main focus is prevention, timely removal of diseased leaves and rational adjustment of density.
Insect pests generally have locusts, scarabs, moths, etc. The maggots are more powerful. They have more than 20 generations in 1 year. The nymphs and adults cluster on leaves, petioles, and young buds. They are harmed by sap and can spray Beijing Green 1000 times. Off. A small amount can be hand-kneaded or sprayed frequently during daily watering.
3. Winter storage method.
In Beijing, it is generally in the mid-to late September that the Lotus has entered a period of decline. The leaves turn yellow and dry, and yellow leaves should be cut off in time to prepare for storage.
Pool storage can be before and after the "11", the basin into the pool. The water was injected to keep the water temperature stored at 0°C to 8°C under the ice for the winter.
The cold cellar is stored in the late October to early November. Put the pot load into the cold cellar, keep the cellar temperature between 0°C and 8°C, keep the pots wet, and you can safely overwinter.
