Hazelnut is a birch bush or small tree of birch family, one of the four major dried fruits in the world. It has strong adaptability. It can grow in mountainous areas, hilly lands, valleys and rivers. It can be planted artificially for 2 to 4 years and the results can be entered in 5 to 7 years. In the full fruit period, obvious economic benefits can be seen in artificially rehabilitating wild hazel forests within 2 to 3 years. Specific plant management methods are as follows:
1. Planting density: When selecting the planting density of hazelnut trees, various factors must be considered in order to make the hazelnut tree grow robustly. In areas with fertile soil and flat topography, hazelnut trees should be planted at a larger distance, and mountainous hazelnuts with large slopes and thin soils can be planted with smaller rows. The varieties with strong growth and open canopy should be planted with larger row spacing, weaker growth, and upright and compact crowns. Hazelnuts can be planted with smaller row spacing. According to the different cultivation purposes, the cultivation density should also be different. In order to achieve early high yields, some plants can be planted densely and densely planted in the early stages, and they can be thinned when the field is closed.
2. Cultivation depth: Planting depth The root system should not be buried too deep or too shallow. It is required that the root neck and the ground surface be 5 cm lower than the ground after planting. Root depth above 6 to 10 cm is appropriate. If the soil in the hole is loose, it is difficult to control the depth of planting to prevent the watering of the soil after planting. Or use your feet to get a little deeper into the soil.
3. Reasonable watering: An irrigated tree tray is built around the hazelnut tree. Its diameter is up to 1 meter, which is convenient for irrigation and water storage. Immediately after planting, water should be poured and irrigation should be done thoroughly. After water infiltration, the soil was sealed and soiled and covered with a plastic film to moisturize the roots, promote the root system activity of hazelnuts, and increase the survival rate.
4. Timely pruning: leaving a trunk, later based on their own growth and development characteristics of pruning, forming a reasonable skeleton. There are 3 types of trees commonly used, such as a little dry cluster shape, a single stem shape, and a multi-dry trunk shape. Less dry plexiform shape, leaving 3 to 4 basal branches as main branches and obliquely extending in different directions. On the main branch of the hazelnut tree, lateral branches were formed, lateral branches were bearing vegetative branches and the resulting mother branches. The overall formation is still happy tree shape, single stem shape, this kind of tree shape to retain a trunk, choose to stay in the main trunk of 3 to 4 uniform distribution of the main branch, select the main branch to stay on the side branch, side branch on the birth of the vice branch and the resulting mother Branches, forming a dwarf trunk.
5. Reasonable fertilization: In the beginning of May, mature farmyard fertilizers were applied and compound fertilizers were recovered in mid-July. In the second year of planting, it is possible to top-coat the outside of the hazelnut canopy, not to chase it too deeply.
6. After planting, dry: Hazelnut trees are planted and dried. The soil with good soil and water conditions should be used as a single-stem tree, with a height of 60 to 70 cm. On the contrary, it should be a plexiform tree with a height of 30 to 40 cm. The seedlings planted in that year must be enhanced with water and fertilizer management to make them grow and develop robustly, sprout a certain number of shoots, have a good degree of lignification, and prevent the hazelnuts from growing in length. After falling leaves in autumn, the soil is protected against cold and the soil can be as high as 1/2 of the plant. In late spring, the cold-proof soil was removed. Generally, it is not necessary to protect the cold from the second year. Http://
