Seabuckthorn cultivation technology
Seabuckthorn, Sea buckwheat branch, seabuckthorn genus, also known as acid willow, acid spine, black spine, etc., is a small berry plant, deciduous shrub or sub-tree, trunk up to 10m, common about 2m. Because it is covered with treasures, it is hailed as "miraculous plants," "green treasures," and "biological weapons that govern the country." It is arid and semi-arid regions with mixed forests of Pinus sylvestris, larch, and spruce. Greening the barren slopes and creating the best afforestation model for soil and water conservation forests. Its cultivation techniques are as follows: 1 The slope of the site is less than 5, and the site can be fully site-stried or land-stripping. The depth of soil preparation is more than 20 cm. When the slope is in the range of 5 to 10, the horizontal trench method should be adopted. When the slope is greater than 10, horizontal land preparation or large fish scale pit preparation, raw soil construction and surface soil filling shall be adopted. The site preparation time is from one quarter to six months before afforestation, and it is better to carry out a year-round and autumn soil preparation one year ahead of schedule. 2 Planting and planting time is best for spring planting. Early planting should be done at a proper time. Usually before germination, the soil is thawed by 20-30 cm. Seedlings are born 1-2 years old. Seedling height 0.4-1m is good. Before planting, planting points should be determined according to the planting design requirements, and then tree planting pits should be excavated at the planting points. The tree pit size is generally 40 cm in diameter and 35 cm in depth. However, the seedlings are buried in the middle of the tree pit and the seedlings are stretched. Fill the soil with the topsoil first and make it close to the roots. When the soil has been filled in most of the soil and has not filled the tree pits, lift the seedlings upwards, so that the roots of the seedlings are in close contact with the soil, practical and filled with soil. Until it is full of pits, it is more practical. Finally, a layer of loose soil is placed on the surfaces of the pits to preserve the soil moisture. In the sand-buckthorn grove in the sand, where there is a need to retain water, it is necessary to surround the sapling or downhill of the sapling. Planting density depends on forest species. General soil and water conservation forest 0.5m0.75m, 0.5m1m or 1m1m; Seabuckthorn afforestation can be 1.5m2.0m, or 3.0m4.0m. When constructing a park on a gentle slope, in order to prevent soil erosion, it should be arranged along the contour line. The seabuckthorn orchards must use high-quality varieties with big fruit, long handle, no thorns, and high yield. Such as Russia's large fruit buckthorn Chuyi, orange, gilt, etc., with the advantages of cold resistance and drought resistance, strong wind and sand, suitable for cultivation in the western region of Heilongjiang Province. Compared with China's seabuckthorn, not only its biological form is good, but also its economic output is high. 3 Young forest tending After afforestation, timely weeding work should be done to prevent overgrown weeds. 4 Rehabilitation of flat ridges The buckthorn forests are prone to ageing, such as dryness and dryness, in relatively dry, barren hills and slopes or on relatively viscous soils. In the practice of the masses, they summed up their experiences of “not using black spines and not cutting long†and “recovering and rejuvenating in a timely mannerâ€. The start date and the interval duration of Pingyi vary according to different conditions and forest types. Generally, it can be carried out during the dormancy period, but it is best if the soil is not thawed in early spring. There are "cutting", "cutting", "cutting", etc. in the flat style. When cutting, it is as low as possible, and it is smooth and indestructible. The dried branches are generally 50%-60% of the fresh weight when they are air-dried. There are a lot of shoots scattered in the flat and the new growth of the new forest can reach about 1m. 5 Prevention and control of pests and diseases The major pests and diseases that currently harm seabuckthorn include seabuckthorn moth, sand fly, and rust disease. The simplest way is to cut off the diseased plants and insects and burn them off as fuel wood. Other preventive measures may also be taken as appropriate. However, we must adhere to the principle of “giving priority to prevention, stressing both prevention and management,†and “governance through drought, smallness, and treatment†to ensure the rapid and high yield of seabuckthorn.
