The pests of Camellia include aphids, scale insects, red spiders, rust ticks, and leaf roller moths. With the addition of rust niches, it can be controlled with general insecticides. The most serious are rust ticks and ticks. The white powder is very small and hard to find. It damages the young shoots of Camellia leaves. The back of the leaves turns yellow, like rust, and the leaves are twisted and unable to grow. . To prevent and treat rust ticks, I have adopted a variety of pesticide control tests and concluded that dicofol and chlorothalonil have the best effects. Rust ticks reproduce most quickly under high temperature and drought conditions. Therefore, it is necessary to do a cool water spray on the gardens, and to cut off the leaves that have been damaged by the rust ticks. The leaves or branches of the existing scale insects can be removed manually, and the insecticides can be removed by using alcohol and alcohol. Camellia on the basin. Flower pots with mud pots (sugar pots, tile pots) are appropriate. Put 3-4 pieces of tile on the bottom hole of the pot first, then fill in a part of the coarse soil, plant the seedling in the pot, fill some fine soil in the root, and slowly put the coarse soil around the pot, gently Beat the basin week, press the basin soil with your hand, and place a part of the soil to shoot. (Pel-earth should be 2-4 cm below the pot opening to allow watering. After the seedling is placed on the pot, the first time it should be poured with enough water, it should be slowly poured to make the pelvic floor water-permeable. The surface of the soil is compacted and the seedlings in the new basin must be sprayed with foliar surface water to keep it moist, avoid water accumulation in the basin, avoid pouring fertilizer, and the watering should be based on the climate and basin soil conditions, and the principle of keeping the soil moist. If there is little or no pouring, pouring must be light.For the mail-ordered Camellia on the pot, 1-2 years old seedlings, first the root mud or mud block, gently wash with water and then on the pot is appropriate, due to seedlings loaded When the box is in order to ensure survival, it usually takes some root soil. These soils are transported very tightly on the way. When they are boxed, they are afraid that the seedlings will be shaken and rooted. Therefore, it is necessary to wash the roots, so that the upper basin can be treated so that the roots can be Fast survival rate is high, middle and large seedlings with more than three years of age need to bring soil ball pots, otherwise it will reduce the survival rate, if the soil ball has been compacted, you can first dip the soil ball in the clear water and immediately pick up, and then use bamboo sticks Loosely loosen the topsoil on the surface of the soil ball and then put on the basin.The basin time: in November or early spring, February-March, north Area should be at the end of March-April early, the condition may also have insulation on the basin in winter.
