Problems solved by technology

Although there are a lot of flowers, the results are few, and the physiological fruit drop is also relatively serious. The output has dropped significantly year by year, which is more than 50% lower than the original output.
Second, the serious occurrence of pests and diseases
[0004] Camellia oleifera low-efficiency forests are mainly managed by individual forest farmers, and the difficulties in the transformation of low-efficiency forests mainly focus on the following points: first, the existing technologies are mostly integrated technologies, which are difficult for forest farmers to master; second, the large investment in technology is difficult for forest farmers to accept; third, the results Difficult to fix, difficult to promote production

Embodiment Construction

[0017] A simple and easy method for tree body rejuvenation of Camellia oleifera low-efficiency forest comprises the following steps:

[0018] (1) Genetic identification, observe and record the yield of tea fruit per plant for 4 consecutive years (two big and small years), and mark the individuals with less fruit per year. On the contrary, unmarked individuals bear more fruit all year round, so it can be considered that the genotype is better and the phenotype is better.

[0019] (2) Diagnosis of cause of formation, diagnosis of cause of cause is carried out for individuals with a small amount of results all the year round. For the individuals that have been marked, is the low yield due to poor genetic quality; or is it due to competitive disadvantages and poor resistance, resulting in growth decline, excessive growth, and serious pest damage.

[0020] (3) According to the diagnosis and adjustment of the cause of formation, cut down those individuals with short growth and seri...

Abstract

The invention discloses a simple and feasible method for rejuvenating a low-efficiency forest tree body of camellia oleifera. The method comprises the following steps of (1) genetic identification: observing and recording a yield of a single camellia oleifera fruit for four consecutive years, and marking individuals with less fruiting amounts throughout the year; (2) cause diagnosis: performing cause diagnosis on the individuals with the less fruiting amounts throughout the year; (3) performing roguing adjustment according to cause diagnosis, and cutting off individuals with short growth vigor and serious disease and pest damage, and meanwhile, carrying out improved variety big seedling supplementary planting on a forest gap and a forest margin vacant land subjected to roguing; and (4) branch cutting and rejuvenation: for individuals kept after roguing, in winter or early spring, cutting off first-stage or second-stage branches with a length of 20-100 cm kept to promote the branches to germinate new branches, selecting 2-3 robust new branches therein to serve as main branches, removing other sprouted branches, and after 2-3 years, forming a new crown by the cut branches.

Description

technical field [0001] The invention relates to a simple and easy method for tree body rejuvenation in Camellia oleifera low-efficiency forest. Background technique [0002] Camellia oleifera (Camellia oleifera Abel) is a unique woody oil tree species in my country. Together with olive, oil palm, and coconut, it is called the four largest woody oil plants in the world, and together with Chinese tallow tree, tung tree and walnut, it is called the four largest woody oil plants in my country. Because tea oil is rich in essential nutrients for the human body, its oil composition is similar to olive oil, even better than olive oil. It is often called "Oriental olive oil" and is recognized as a green and healthy edible oil in the world. In recent years, with people's pursuit of health and the national grain and oil safety strategy, camellia oleifera and camellia oil have gradually aroused new social awareness, and the camellia oleifera industry has also developed rapidly. [0003...
