1. Several reasons for the low yield of rape:

1. Irregular management

Because of the existence of market factors, including the lack of understanding of the production of Camellia oleifera and insufficient capital investment, the forests of Camellia oleifera were lack of management for a long time, overgrown with weeds, unevenly distributed, almost in a semi-abandoned state, and very poor ventilation conditions. Well, the damage caused by pests is very serious, and the output of Camellia oleifera is very low.

2. Lack of capital investment and technological services, and lack of production base

Farmers cannot afford to invest in new varieties of Camellia oleifera and carry out transformations at the same time. The government's support for the Camellia oleifera industry is insufficient and there is no continuity. In addition, there is a lack of funding, scientific and technical guidance, and a lack of professional and technical personnel. In terms of the operation of camellia oil, the pace of transformation of low-yielding camellia forest has been slowed down.

3. The variety is messy

Low-yield Camellia oleifera forests often use seeds for direct sowing, resulting in low seedling rate and serious plant shortage. Long-term alienation and pollination have led to very messy varieties of Camellia oleifera forests. The proportion of inferior plants is relatively large. The difference in plant yield Also very big. The chaotic growth of Camellia oleifera varieties with great differences in flowering, fruit shape, and maturity often occurs in low-yield forest areas.

4. Serious tree aging

Because of the long-term lack of management, the tree body is generally weak, and the phenomenon of tree aging is also very obvious. The individual has entered the senescence stage ahead of time, the physiological function is reduced, and the roots' ability to absorb nutrients and the ability of leaves to light and react are constantly weakening , Did not provide sufficient nutrients for the growth and development of plants, the production was significantly reduced, the phenomenon of plant dying became more and more serious, there were many lichens attached to the plants, pests were increasing in large numbers, and the phenomenon of flower and fruit drop was very serious.

The low yield of rape is mainly due to these reasons, growers must know!

2. How to transform low-yield rapeseed forest?

According to the actual conditions of the low-yield forests of camellia oil, the structure of the forest stand and the conditions of the land should be improved for the first two conditions. The third forest area should be selected with better land conditions. For the forest land with development potential, the varieties are updated, and the fourth kind of forest land can be transformed according to the requirements of classified yield.

1. Improve soil conditions

(1) Repeated cultivation

Deep plowing and reclamation can obviously promote the growth and development of Camellia oleifera, and the output has been greatly improved. In the first winter of the transformation, all the land should be reclaimed once, with a depth of about ten to twenty centimeters. In the next two to three years, it will also be deep-turned. The deep-turning must be combined with organic fertilizer. Fertilize the canopy as required. Plowing is also carried out every summer, with a depth of about ten centimeters. Weeds should be removed during reclamation, the soil should be loosened, and horizontal ladders should be made to protect the soil, fertilizer, and moisture.

(2) Increase water and fertilize

One of the main reasons for the low-yield forest of Camellia oleifera is the lack of fertilizers. Combining with repeated cultivation and adding fertilizers, the output of Camellia oleifera can be greatly improved. Organic fertilizer is the mainstay in the new year, and nitrogen fertilizer is used in the young. It is organic fertilizer, and it is quick-acting fertilizer in spring and summer. Fertilize the forest land in accordance with the fertilizer requirements.

3. Strengthen the prevention and control of pests and diseases

Camellia oleifera is easily affected by pests and diseases. The prevention and control of pests and diseases must be strengthened, efforts should be made to improve the ecological environment, and biochemical control methods are adopted to solve the problems of pests and diseases.
