Zirconium is a shrub or a wood, one of the world's four main dry fruits, which is adaptable, can grow in mountains, hills, ditches, riversides, with the results starting from 2 to 4 years of artificial planting, 5 to 7 years of fertilisation and recovery. For two to three years, lin will see obvious economic benefits, with high planting prospects, so let's look at the planting techniques of the sap
Conditions for the planting of tarts
1 temperature: different types of eucalyptus tree with different requirements for temperature. O'hare is warm and wet. An average temperature of 13-15°c, absolute lowest - 10°c, and an extremely high temperature of 38°c. Pygmy species are more resistant to the cold than europeans and are suitable for average annual temperatures of 7. 5-13°c, with a minimum temperature of 30°c。
2. Light: the sorghum tree is a radiant plant, generally requiring an annual daylight time of more than 2100 hours, otherwise the buds are less formed and less productive。
3 soils: the sorghum trees grow on fertile, well-breeded sandy sandy soil, especially the pyrotechnics, which require high levels of soil, dry sand, clayy soil, marshlands, saline and low-lying lands. Pyro hybrids require soil ph of 6. 5-7. 5 and euro5-7。
It's the breeding technique of the sting
Reproduction: in the wild sorghum forest, a rich, fruit-rich, pest-free collection is chosen for the harvesting of parent trees, from which large, full-bred, pest-free sorghums are selected for seeding. The seed of the apricot remains fertilized for a year. The planting time is suitable for the spring, usually in mid-april. It is 60 cm from 60 cm from 6 to 8 cm from bed and 20 cm from 5 to 6 cm from bed. When seeding, a ditch is opened on the flat surface, deep between 5 and 6 cm. The pure seed sifted from the wet sand is then spilled under the gutter at the distance of the above-mentioned line, with a small pressure of between 3 and 5 cm。
2. Divisional reproduction: there are two ways to reproduce in separate strains, the first of which is to dig up all the mother's strains into small clusters or single strains, each with roots and one or two branches. The second is to dig the roots around the mother's pool and separate several plants, which remain. The saplings shall be kept at 20 cm in length and shall have a number of roots. Upon separation of seedlings from the matrix, the branches shall be cut short, 15 to 20 cm long, and shall be implanted immediately, wet and protected against loss of water。
3. Root reproduction: there are two ways in which root breeding can take place, namely, by digging up the roots around the existing piles and obtaining the trees. The second is reproduction in a special parent garden. Mother strains for breeding should be flattened in the spring to promote rooting in the range. During the period of growth, sufficient fat and water supplies are ensured, and the roots are duly trimmed, so that the roots are not too dense, both to ensure that the roots are well developed and to facilitate seeding in the autumn。
4. Pressure reproduction
Level 1 pressure: this can be done in autumn or spring, but most appropriately in spring. Pulls out the growth of the year's branches and lays them on the ground, secures them and does not crush the soil. Carefully protect the buds and make them grow. In this way, almost all buds at the horizontal level can grow a little more. When new ones are up to 10 to 15 centimetres, two to three rounds of soft wire are used in each section of the year to promote new roots. Then two thirds of the height of the new soil will be bred, and then the soil will be bred one to two times according to the new growth height. When leaves fall in the fall, each section is cut apart, i. E. A tree with a vertically new tree with roots in the base。
Two bows: bows are divided into hard and young. In the early springs, the hard-wire stubbles were dug 15 to 20 cm deep along the herds, spreading the fatty of the well-scathed farmers into the gutter and keeping the gutter 10 to 15 cm deep. The distance between the ditch and the backbone of the bush is appropriate when the branch bends and the bottom of the ditch can be touched. Choose a well-developed year and bend to the bottom of the ditch. Hold it, then crush it with earth and fill the ditch and grow it. In this way, the sprouted branches that are exposed to the ground grow long and lay their roots in parts of the earth. In order to encourage the branches to take root well, they may also be partially circumcised with a width of 1 to 2 mm, removed from the pelvis, or cut horizontally. In early and mid-june, when the primary branch grows between 60 and 80 centimetres, the method is the same as the hard branch。
Cultivation management
1. Cultivation density: the planting density of sorghum trees should be justified if they are to be productive. Reasonable selection of plant density of sorghum trees is closely linked to a number of factors, such as species, varieties, logs, planting techniques, tree shapes used, topography, soil and climatic conditions. Therefore, multiple factors should be taken into account when choosing the density of the seedling tree so that it can grow robustly。
2. Cultivation density: in fertile and flat land areas, the planting distance of the sorghum tree should be greater, the slopes greater, and the planting distance of the scavenger mountain plantations smaller. The growing species and the opening of the tree canopy should grow a much larger range, a much smaller range, and a much smaller range. Cultivation density should vary depending on the purpose of cultivation. Some could be planned for early productive use, which could be planted early and cut off from time to time when the lands were closed。
3. Cultivation depth: the planting depth root system cannot be buried too deep or too shallow, requiring the planting of the back neck and the ground or slightly less than 5 cm. It is appropriate to use the roots above the burial depth of 6-10 cm. In the event of laxation of the soil within the den, which makes it difficult to manage the depth of the plant in order to prevent subsequent watering, the water should be duly watered before planting. Or put a little foot on the inner ground。
4. Reasonable watering: water piping is built around the scallop tree, with a diameter of 1 m, which allows for irrigation and storage. Once established, water is to be poured immediately and sufficient to fill it. The water seeps are covered with earthen cover and covered with membranes in order to keep the tree warm, to promote rooting activity and to improve the survival rate。
5. Cuts in due course: a main stem is left behind, which is subsequently reconstructed in accordance with its own growth and development characteristics to form a reasonable skeleton. There are three types of trees that are commonly used, with small dry bush formations, single dry formations, multi-dry bush formations. Small dry-crowded, with three to four primary branches as main branches and tilted in different directions. The branches of the scallopy tree bear branches that produce nutrient branches and fruit branches. The whole tree is still a happy tree, a single stem, which retains a backbone, with three or four equally distributed branches on the backbone, branches on the main branch, branches on the side, branches on the side, branches on the side, branches on the side, and branches on the outcome, forming a dwarf backbone。
6. Rational application of fertilizers: fertilizers for grown farmers were applied in early may, and compound fertilizer was pursued in mid-july. The second year of planting can be followed by a projection outside the crown of the scallop, not too deep。
7 post-plant drying: zirconium tree drying, single drying and bush formation. Land in good conditions of fertilized soil should be in the form of a single dry tree, with a dry height of 60 to 70 centimetres and, conversely, in the form of a bush, with a dry height of 30 to 40 centimetres. The seedlings that were planted during the year were designed to strengthen the management of water fertilizers so that they could grow and grow strong, produce a certain number of branches, have a good degree of woodification, and prevent the growth of scallop trees. After falling from the leaves in the autumn, the soil is prepared for cold, up to a second of the plants. In the following spring, the land will be removed from the cold, which will normally be avoided in the second year。
