One, fertilization drought
1, fertilization
Oil tea in the growth process is very much in need of fertilizer, fertilizer can contribute to the growth of young forests lush, early flowering and fruiting, especially after planting 1-2 years of fertilization, especially important.
Because the place of planting oil tea, more on the slopes, low fertility, acidity, sticky heavy, barren and easy to dry, such as timely fertilization, will inevitably withered branches and leaves, into the "old seedling", and later it is difficult to "turn around".
After fertilization, the forest floor is conducive to the growth and development of the oil tea root system, the root system can absorb more water and fertilizer to meet the needs of oil tea growth and development.
Fertilized oil tea has the advantages of good growth and development, blossoming and fruiting, and high yield.
The main young forest fertilizer for oil tea is organic fertilizer, the fertilizer can be cultivated locally or fertilizer distribution, in order to reduce the loss of fertilizer in the young forest of oil tea, the appropriate application of nitrogen fertilizer can promote the growth of the oil tea forest, no matter which kind of fertilizer, you need to dig a trench, dig a hole and apply it in the young forest of oil tea.
2, drought
July-August drought season, a great threat to the oil tea young forests, especially the direct seeding of 1-year-old seedlings; rooting is very shallow, the root system is undeveloped, intolerant of drought, you can timely shallow plowing loosening, cut off the soil capillaries, reduce the evaporation of soil moisture, but also cut grass to cover around the oil tea tree court, to prevent the sun from direct sunlight, reduce the soil temperature.
In places with conditions, you can use water to drench or watering, drought protection seedlings.
Two, plastic pruning
1, stem
Oil tea trunk height should be set reasonably, too high and too low are not good, in addition to specializing in the cultivation of a short crown, the general height of 60 cm or so is appropriate.
2, wipe bud
In good management of some oil tea can be harvested in 2~3 years after flowering, but in order to promote the growth and development of the tree, the formation of a tall crown, it is best not to let the oil tea premature flowering and fruiting, and as soon as possible to erase the flower buds.
In 4~5 years, the middle and upper flower buds should be removed appropriately and nutrients and water concentration should be utilized for branch growth, branch strengthening and crown expansion.
Middle, lower, and inner branches can be allowed to fruit properly.
3, pest control
Oil tea young forest period pests, mainly leaf-feeding pests.
Pests often bite off the young leaves and tips, affecting growth.
Particularly with the old oil tea forest adjacent to the place especially more serious.
You can use 800-1,000 times the liquid solution of Lego to prevent and spray to kill, the effect is better.
Every 5-7 days, spray 1 time, spray 3-4 times can be prevented, after spraying, such as rain, after clearing the sky to re-spray.
4, the protection of terraced ridge
For the oil tea garden, everywhere in the renovation of terraced terraces, camping a large area of oil tea fast-growing and productive experimental forests and renovation of the "three guarantees", the transformation of the old forest.
How to protect the terraced soil terraces of the edge of the ridge, is a very important work, but also to ensure that there is a kind of income, high and stable production of oil tea is an important measure.
Planting crops in the terraces, the best horizontal strip ditch sowing, blocking precipitation.
When sowing seeds at the point, it is best to arrange the planting points in a triangular way, which can make full use of the ground, sunlight, and can reduce soil erosion.
In places where it is possible to do so, use stones to build up a ridge, or drive a row of stakes to reinforce the edge of the ridge.
The ridge should be inclined to ensure safety.
The above is about the oil tea planting to improve the yield of management techniques, in order to effectively ensure the benefits of the growers, we must do a good job of these management measures when planting, about the oil tea planting, do you have anything to add?
