A, garden selection Laurel in the plains, hills and mountains can be planted. "If you transplant, you have to choose a high mound". In the hills and low hills planting osmanthus, sunshine, air circulation, good drainage, very conducive to the growth of osmanthus, to 5 ° ~ 1 5 ° angle of the gentle slope of the most ideal. Planting osmanthus in the flat land, you should choose a place with high and dry terrain, good drainage, loose soil, rich in organic matter, acidic or slightly acidic. According to the actual situation of the local soil, choose the appropriate planting garden, because the growth and development of osmanthus after planting and flowering. With the planting of the soil properties of the plot, the relationship is great. Second, land preparation After the selection of the garden, depending on the specific circumstances of the meticulous and strict land preparation and soil improvement, so that the garden soil can be deep plowing and maturation. Ground preparation should be carried out as early as possible, to give full play to the role of soil water retention and moisture conservation, to ensure that the planting work in a timely manner. Generally speaking, land preparation should be carried out 3 months before planting. The law of land preparation varies according to the area, slope, soil conditions and ground conditions. In the barren hills and grassy slopes, bushes and persistent weeds should be removed first, and the undulating small terrain should be leveled, and then ground preparation should be carried out. In the hilly mountainous area, if the slope is gentle, the soil layer is deep, can be made horizontal strip of land preparation; if the slope is large, it is necessary to take certain soil and water conservation measures. Third, planting season, density and method of laurel main root is not obvious, lateral roots and fibrous roots are very developed, is a kind of transplantation resistance and planting survival rate of high garden species. In addition to the hot summer season and cold winter season, other times can be planted. But no matter when to plant, osmanthus saplings need to have a complete soil ball and make appropriate pruning. The planting density of osmanthus depends on the purpose of cultivation, the traits of the species and the conditions of the site. In general, as an ornamental garden tree species, its density than the harvest of osmanthus economic tree species, some dense, large areas into ornamental forest planting, usually 2.5 meters × 2.5 meters, as an economic tree species planting density of 4 meters × 4 meters. Planting osmanthus trees often use the hole planting method. Before starting seedlings, first planting hole dug well. The diameter of the hole is larger than the root of the seedling with the soil ball O.5 ~ 0.6 meters, so that when planting in the soil ball around the soil pounding, so that the soil ball and the hole of the soil tightly combined. The depth of the hole than the seedling with the ball of the island of 0.2 ~ O.3 meters. When digging the hole, the topsoil and the heart of the soil separate piles, in order to fill the soil first fill the topsoil after filling the heart of the soil. After digging a good hole, it is best to apply basic fertilizer. On top of the base fertilizer, fill in about 10 cm thick soil, so that the base fertilizer does not come into direct contact with the soil ball to prevent root burning. When planting, the osmanthus seedlings will be placed in the pre-dug planting hole, cut the grass rope of the crown, adjust the ornamental surface, so that the tree is upright, and fill in a small amount of topsoil to fix the soil ball. Then cut open the tying material and fill in the topsoil. Fill to half, use a thick stick to tamp the earth ball around. Then continue to fill the hearts of the soil, mulch than the original soil ball height 0.1 ~ O.2 meters is appropriate. If the plant is taller, planting needs to be fixed with a stake support. Seedlings planted, around the soil ridge. And timely watering, to the extent that no longer seepage. Osmanthus seedlings planted, should also implement appropriate pruning. Fourth, woodland intercropping hilly and mountainous areas of the osmanthus garden. In the first few years after planting, in order to make full use of the land, and promote the growth of young osmanthus, should be implemented as far as possible in the young forest rows of various intercropping. In this way, not only can make full use of the land, increase economic income, but also in the management of crops at the same time to nurture the young forest of osmanthus. The type of crops to be used with osmanthus should be legumes or other short-strawed crops. This is because legumes have rhizoma nitrogen-fixing bacteria, can fix the nitrogen in the soil air, increase soil fertility. Some crops after harvest. Its straw can also be used as fertilizer, buried in the soil, can increase the organic matter in the soil. And high straw crops, such as cotton and corn, because they will affect the woodland ventilation and light. Consume a lot of fertilizer, but also cause osmanthus disease and insect hazards, not conducive to the growth of osmanthus, so it is not suitable for intercropping. Forest farmers intercropping can generally be carried out 2 to 3 years. Interplanting, crops and osmanthus seedlings between rows, should maintain a distance of at least 0.5 meters. In order to avoid intercrops and young laurel trees compete for fertilizer and light. The forest land should be frequently loosened and weeded, so that it is always clean and no grass and soil soft state. Forestry and agriculture intercropping, can also consider intercropping green manure, to achieve the purpose of fertilizer to feed the land. Fifth, grafting propagation is to be propagated part of the plant body connected to the stem or root of another plant so that the two combined into one. Form an independent new plant a propagation method, through the grafting propagation produced by the plant body is called "grafted seedling" for grafting with the branches or buds called "scion". Grafted seedlings differ from other nutrient-propagated seedlings in that. It utilizes the root system of another plant. And bear the scion of the rooted plant part is called "rootstock". The use of branches and stems as scion is called "branching". With buds as the scion is called "budding". Grafting is a very important method of osmanthus seedling production. It has the advantages of general nutritional propagation. Also has other nutritional propagation can not play the role of dumping to maintain the excellent characteristics of plant quality. Improve the ornamental value. Increase resistance and adaptability. Early flowering and fruiting. Overcome the phenomenon of not easy to reproduce． Expand the reproduction coefficient. Restore tree strength and save wounds． Replenish missing branches. Renewal of varieties. The principle of grafting survival osmanthus grafting survival prerequisites, mainly depends on the rootstock and scion affinity and affinity as well as both sides of the regenerative capacity of the cells of the formation layer. When the two grafted. The thin-walled cells of the formation layer divide. Formation of healing tissue. And gradually differentiated to form the conduction tissue when the rootstock and scion conduction tissue connected to each other. Enable water and nutrient transport. Can maintain water balance to show that the grafted part of the combination into a whole. Grow into a new plant. In technical measures. In addition to the genetic characteristics of the tree species to consider the affinity of the grafting of the main key to success: the scion and the rootstock between the formation of the layer of tightly integrated junction surface the larger the contact surface is smooth. Each part of the grafting aligned, tightly bundled only the more likely to survive, in general. Rootstock and scion affinity the closer the stronger the affinity. In the genus and the genus and the species and the species and the species asked the same species grafting affinity is the strongest. Interspecies followed by the genus again. General rootstock to choose the best 2-year-old seedlings. Scion to the periphery of the crown of the development of strong, full buds 1 year old branch is better. Branching is generally carried out in the spring from March to April, budding is generally carried out in the summer and fall from June to September. Northern regions generally from March 20 to April 10 or so for the best because at this time the sap began to flow. Cell division is active. Grafting interface healing fast and easy to survive.
