What kind of temperature is suitable for planting camellia oleifera? The average monthly temperature reaches 3℃ in the coldest time and 365438 0℃ in the hottest time. As long as there are such temperature conditions, it is very suitable for planting camellia oleifera.
Some people think that the output of Camellia oleifera is low, and this does not count. Actually, this is not necessarily the case. Camellia oleifera is planted in some places, so the yield is low, mainly because there are many barren areas and there is no reclamation. Once the camellia oleifera is reclaimed, it will benefit in the same year, increase production in two years and harvest in three years. Another reason is extensive management, with little shallow planing in summer and little deep digging in winter. The anthracnose of Camellia oleifera is serious, and the flower and fruit drop are serious, so the prevention and control of anthracnose must be done well. You can spray yellow mud and lime water in time when you get sick easily after taking a hot bath in summer. The ratio of yellow mud, lime and water is 1: 1: 10. In addition, picking camellia seeds too early or too late will affect the yield, so it is necessary to pick them in time.
Tea oil pressing is very technical, so be careful not to break the silk. Once the silk is broken, there is no more oil. Squeeze with a shell, keep squeezing, squeeze more and more tightly, in one go.
To develop Camellia oleifera production, we should pay special attention to several links.
First of all, let everyone understand that it is of great significance for oil to go up the mountain and woody. Planting camellia oleifera well can not only solve the problem of mountain farmers eating oil by themselves, but also increase their economic income.
Secondly, the existing Camellia oleifera forest should be reclaimed. All the miscellaneous trees and shrubs in Camellia oleifera forest should be cut down, dug and planted again. "Winter goes to spring to dig seven inches of grass, and summer to dig three inches of grass to bury the roots." According to past experience, the newly reclaimed Camellia oleifera forest was seriously ill, and Bordeaux mixture should be sprayed once after reclamation to prevent diseases. The preparation method of Bordeaux mixture is as follows. Dissolve one catty of copper sulfate and one catty of quicklime in two buckets of water of 50 catties each, and then fully mix the two solutions together.
In addition, while reclaiming the existing camellia oleifera forest, we should also develop new camellia oleifera forest. In this regard, it is mainly to do the following work:
First, we must choose the right species. There are seven varieties in our province, such as scarlet, scarlet, Daqing, Xiaoqing, pumpkin, lotus color and chicken heart. Among them, scarlet and pumpkin are the best varieties.
The second is to raise seedlings and improve the germination rate. If there is no animal harm, it is best to sow in winter. In recent years, container seedling raising method has been adopted in many places, and the effect is good. Among them, it is best to raise seedlings in nutrient bags (nutrient bags are made of plastic paper).
The third is good. The planting distance should be appropriate. The top of the mountain is shallow and the trees are small, so it is necessary to plant them densely. The plant spacing can be 7×8 city feet, and 107 plants can be planted per mu. The soil layer at the foot of the mountain is deep and the trees are large, so it can be planted sparsely. The plant spacing is 8×9 city feet, and 83 plants can be planted per mu.
Fourth, in the young forest period, some crops can be planted alternately for cultivation, instead of stroking, or mixed forests can be picked, preferably mixed with tung oil trees, and grow in a short time.
Fifth, do a good job in soil and water conservation. Sixth, we should dig in summer and dig in winter, fertilize properly, and it is best to serve tea cakes.
