1. Planting time Yangmei is an evergreen tree. In southern China, it should be in the spring from March to March. After the freezing period, Yangmei begins to colonize before germination, and it is better to choose cloudy or light rain.
2. The planting area of ​​Yangmei is shade-tolerant and humid, and the average annual temperature is 15 to 21°C, and the minimum temperature is -8°C or above. The area where annual rainfall is not less than 1000mm can be cultivated economically. The most suitable area for Yangmei is below 500 meters above sea level. There are some kinds of indicator plants such as ferns and rhododendrons on the mountain. It does not accumulate water, and it is cultivated on the hilly land where it is relatively humid.
3. Before planting, plant the hole and plant the planting hole before planting. The digging hole should be carried out in the winter to help reduce the soil pests and diseases. It is better to dig into the fish scale pit on the contour line, with a size of 1 meter square and a depth of 0.8 meters; topsoil and heart The soil should be separated so that it can be used in layers when filling. Apply basal fertilizer, apply 25 kg of manure (or 3 kg of vegetable cake) per hole and 10-15 kg of coke ash, add 0.5 kg of superphosphate, mix it with soil when planting, and avoid roots and fertilizer when planting. Contact, especially superphosphate. The weeds and trees around the fish scale pit should not be immediately removed. After the seedlings have survived, the tall trees will be cut off.
4. Planting strong seedlings Choose stout seedlings with a few branches and no roots. After the seedlings are lifted, the root system will be used to make yellow mud, which will be wrapped in nylon film and transported again. The maximum time from raising to planting should not exceed 10 days. Before planting, cut more than 1/3 of the leaves of the seedling grafting interface to reduce evaporation of water to facilitate survival and growth after survival.
5. In order to increase the survival rate, the planting method should not be shallow when planting, especially where the autumn drought is heavy. All the old scions on the rootstock should be buried under the soil, and at least 3 to 5 leaves should be buried in the soil to make the scions root. If the species is shallow and the old scion surface is exposed, the survival rate is low, which is the key to the survival of Yangmei. Before planting, all the leaves should be cut off, leave the petiole, and remove the nylon film on the scion. If there is a root in the cut, apply a pruning shear to cut the wound. At the same time, attention should be paid to the work done in order to ensure that the center dry height above the interface is approximately 25 cm. When planting, first cover a layer of 15-20 cm thick top soil on the fertilizer, which is the soil that is in direct contact with the root. Put down the seedlings, straighten out the root system, fill the topsoil several times, and make sure that the top is covered with earth and 20-30 cm above the ground. Then water 1 or 2 times and cover with a layer of loose soil.
6. In the first year after the establishment of drought and drought resistance, the root system of undergraduates was underdeveloped. During the high-temperature and drought conditions in July-August, it was easy to be drowned and should be used to prevent drought and drought. There are water sources for possible irrigation or watering; it is also possible to cover 5 to 10 cm thick grasses in the fish scale pit area after drought (July) and to prevent drought and drought.
Activated carbon is a material which commonly used in air purification, mainly used to adsorb the few toxic gases, ammonia, formaldehyde and benzene without pollution,toxic and side effects. The effect of activated carbon
1.Indoor air purification. After the bedroom decoration, we can place activated carbon to absorb harmful gases,you can also put it in toilet to remove odors.
2. Furniture purification. Put the activated carbon into the closet to remove strange smell, humidification and mildew; put it into the shoes which can remove odors and germs; put it into the refrigerator to prevent food cross-taste and pollution that keep food fresh .
3.Floor protection. When the floor is paved with activated carbon directly under the floor which can go to taste humidification, mildew and pest control, but also to avoid the floor deformation.
4. Active carbon mattress. The mattress added activated carbon can absorb moisture, remove sweat and keep the bed clean; secondly, it can improve the health function of lumbar muscle strain for the elderly. Because it has infrared radiation with a certain temperature, human body has health effect when long-term use.
5.Put activated carbon into the car, it adsorb harmful gas inside the car and remove peculiar smell.
6. Used for pet cleaning to adsorb odor which is non-toxic, no side effects, and no harm.
7. Put the activated carbon next to the appliance to prevent electromagnetic damage.
8. Activated carbon can be placed in the fish tank and swimming pool for disinfection and purification of water.
