Can Lian Wu be cultivated in Fuyang?

Growth habit: Lotus fog likes temperature and is afraid of cold, and the optimum growth temperature is 25 ~ 30℃. There is no need for freezing injury in winter; At 7℃, the buds and young fruits were damaged by cold and fell off. When 10℃, the fruit near harvest will also be damaged and fall off.

Lotus mist requires high water content and adapts to different soil conditions. Lianwu likes moist soil and needs sufficient water supply all year round. All the lotus seeds near the water will grow vigorously and have strong waterlogging resistance, and the places that are often soaked will also grow normally, blossom and bear fruit. At the same time, the requirements for soil conditions are not strict, and sand, clay, red soil, slightly acidic or alkaline soil can be planted. Weak alkaline clay loam with good irrigation conditions is the best cash crop.

Replication technology

Air layering: air layering method (i.e. ring branch propagation) is mainly adopted, which is carried out in the rainy season with high temperature and humidity from May to September every year. Selecting fully developed branches with a diameter of about 3cm, firstly peeling them in a ring shape with a length of about 3cm at the base, then wrapping them with mud balls mixed with wet soil and grass on the upper and lower sides, then wrapping them with transparent tape, and tying the upper and lower ends tightly with nylon ropes. After about 1 month, new roots grow on the top of the peeling place; After about 3 months, new roots grow in large quantities, and they are cut off below the roots to form independent seedlings. First, heel in continued to be cultivated in the nursery, and then planted in the ground in the following spring.

Cutting: select 2-3 year-old branches, with the length of 15-20cm, insert them into sand bed for 2/3, pay attention to shading and moisturizing, take root in1-February, or dry or raise seedlings. It can be planted in the spring of February-April or in the autumn of August-September. In areas with high temperature, it can also be planted in11-65438+February. The row spacing is 4x5m at first, and it will be refined to 8 x 8 meters in a few years.

Sowing: It is suitable for planting lotus seeds in spring, and the row spacing is 4m×5m. Dig big pits, fertilize and plant big seedlings. The hole should be dug 1 m square, and the garbage, soil and fertilizer should be 50 kg per hole. Seedling raising requires first-class seedlings, about 500 plants per hectare, and then gradually thinning.

Flower-forcing treatment: in order to obtain multiple production in one year, flower-forcing treatment can be carried out:

Soak the fruit in water 1.5 months after picking in July.

Tree-ring injury is mainly caused by beating the bark around the tree trunk with a mallet to make it loose. In July-September when the temperature is high, it is difficult to heal at low temperature. Bending branches, a vigorous old tree, can bend the upright branches horizontally or even droop.
