Oil and tea is a natural and advanced pigment unique to our country and can be used as oil in daily life, as well as as as lubricating oil or rustproof oil in the chemical industry, and tea cakes can be used as agricultural fertilizers or pesticides. As modern scientific and technological methods continue to evolve, and as mountain tea cultivation technologies continue to innovate, this paper mainly discusses and analyses the establishment and management of oil and tea plantations for sustainable development。
Choice of oil and tea woodland. Environmental factors are important for the growth of oil tea, such as sufficient sunlight, warm and wet climates and relatively broad soil conditions. They can grow well under various soil conditions. Typically, they are acidic and good soils, and have characteristics such as drainage that are more conducive to the growth of oily tea trees. Typically, oily woodlands are selected for relative stability in the central and lower parts of the slopes and other areas above 100 metres above sea level and below 500 metres. Fire lines should be set around the forest land。
After selecting the oil tea from the forest land, the forest land is cleaned and cleaned to remove the weeds from the forest land and various woody plants. After clearing the forest, dig the pit. The size of the pit remained essentially at a depth of about 30-40 cm. The length and width are approximately 40-50 cm, and the soil of the pit centre accumulates around the pit to facilitate backfilling. The backfill height is about 10 cm above the surface, which is more conducive to the cultivation and growth of mountain tea trees。
Choice of oil and tea varieties. Proper selection of oil and tea species is important for increasing production of oil and tea. It was therefore necessary to select varieties that would facilitate large-scale cultivation and high productivity. At the same time, the selection of oil and tea varieties is mainly combined with the terrain, climate and temperature of the areas where the oil and tea trees are grown. Specific conditions such as soil。
How to grow oil tea. In order to improve the economic benefits of oil and tea cultivation, in addition to the proper selection of the area and varieties of oil and tea cultivation, a rational method of cultivation should be chosen, consisting mainly of the following:
First, the intensity of the cultivation of oil and tea is reasonably sown in accordance with the characteristics of the selected varieties of tea and in the climate and terrain of the mountain areas where the tea is grown, and it is ensured that there is sufficient sunlight for light co-operation in each of the seedlings in order to increase the production and efficiency of the tea。
Second, the main mountain tea was grown in southern china when the tea was grown, and in autumn and winter, specific planting times were usually the best, especially when the soil and pits were damp after the rains. Oil and tea cultivation works best。
Thirdly, in the process of oil and tea cultivation, it is necessary to ensure that each mountain tree seedling is accurately planted in the pit centre and that its roots are approximately 3 cm deep to ensure the healthy growth of its seedlings. Fourth, the filling process of oil tea is also important, and when it is poured into the wet topsoil, it must adhere to the principles of filling-pressure-pressure-pressure and ensure that the soil is refilled at a height of about 10 cm. More than the surface. The final pressure resulted in topsoil being added to the surface to prevent water evaporation, thereby effectively ensuring the survival of the growing tea plant。
Fertilizer methods for oil and tea cultivation. For fertilizer applications for oil and tea cultivation, first, appropriate composite fertilizers are mixed with the soil of the pit floor after the pit has been dug, and secondly, two more complex fertilizers are applied after the soil of the cultivated tea plant has been refilled. Up to half, or after planting a tea plant, digs a pit about 30 cm deep or 20 cm deep near the plant to apply composite fertilizers to ensure that each plant is properly fatted. Finally, as the mountain tea tree grows, it is appropriate for the mountain tea tree to catch the fat. Fertilizers can be effective in ensuring the normal growth of oil and tea plants and can contribute to improved production and efficiency。
Management of oil and tea woodland. When oil tea is planted in the forest, the forest area should be managed rationally by the grower in order to effectively ensure its growth。
Management of oil tea and juvenile forests. In the early stages of oil and tea cultivation, weeding, fertilization, watering and laxation are needed in the larvae. It is important to note that weeding in the oil and tea larvae should not choose high temperatures, which could lead to sudden death of the seedlings. Depending on the growth of the seedlings, water is properly poured in the dry and wet conditions of the larvae to ensure that the oiled tea plants grow in sufficient moisture, while the use of nitrogen, phosphorus, potassium compound fertilizer and a suitable quantity of special mountain tea fertilizer is determined by the growth of the oil tea. Mountain tea tree. Appropriate adjustments can effectively guarantee the fertilizer needed for mountain tea growth。
The cut of the oil and tea plant. When oil and tea trees are grown and shaped, they shall be trimmed and shall be guided by the following principles: (1) the main branch of the oil and tea tree shall first be determined according to the manner in which the oil and tea plants are grown, and then the main branch of the oil and tea tree. Ensure that branches have the appropriate level and number. (2) you need to trim the oily tea plant. The first trimulation was mainly to retain three to five main branches, the rest of which were cut off. In the second year, a second trim. When the main branch of the first trimulation is well developed, secondary main branches are grown on each of the main branches, other intensive branches, small branches, overlapping branches, etc. (3) interrupted once a year to cut branches below the first main branch and branches of pests, feet and underground growth。
Prevention of diseases and pests of oil tea. The growth of oil and tea plants will be threatened by pests such as anthrax, molluscs, sacred beetle, beetles, tea flowers, etc. In order to prevent and control the pests and diseases of mountain tea, the principle of prevention is first and foremost prevention. The main preventive methods include (1) physical control. Pre-afforestation should control the origin of pathogens and insects in mountain tea forests and their surroundings and choose to be resistant to pests. Good varieties, adjusted planting density, improved sanitation in forest areas, and improved anti-virus plants for oil and tea. (2) chemical agents control, with different chemicals selected for different types of pests and pests, but it should be noted that, when chemicals are used, the dose and time of the various substances must be controlled to ensure effective threat prevention. Insects. At the same time, it is effective to ensure that tea plants are not destroyed by drugs and can grow steadily。
Conclusions. At present, products such as oil and tea processed edible oil and lubricants are widely used in people's daily lives, market demand is increasing, market prices are relatively high and the costs of developing oil and tea are relatively low. As a result, more companies and individuals have invested in the mountain tea and tea industry, while government departments have expanded the range of mountain tea growing and introduced advanced mountain tea cultivation techniques, managed mountain tea plantations, significantly improved the production and quality of mountain tea, improved economic efficiency and sustainable economic development。
