The low yield of rape is mainly due to these reasons

1. Several reasons for the low yield of rapeseed:

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 diseases and insects is very serious, and the output of Camellia oleifera is very low.

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

Farmers cannot afford to invest in new varieties of Camellia oleifera and reform 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 oleifera 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 lack of plants. Long-term alienation and pollination lead to very messy varieties of Camellia oleifera forests. The proportion of inferior plants is relatively large, and the plant yields are different. It's also very big. The chaotic growth of Camellia oleifera varieties with great differences in flowering period, fruit shape, and maturity period often occurs in low-yield forest areas of Camellia oleifera.

4. The aging of the tree is serious

Because of the long-term lack of management, the tree body is generally weak, and the phenomenon of tree age 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 volume was significantly reduced, the phenomenon of plant dying became more and more serious, the plants attached to these many lichens, etc., pests increased in large numbers, and the phenomenon of falling flowers and fruits 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 camellia oil forests, the forest stand structure and land conditions should be improved for the first two situations. For the third forest area, the better land conditions should be selected. The forest land with development potential is renewed, and the forest land of the fourth species can be transformed according to the requirements of classified yield.

1. Improve soil conditions

(1) Repeated reclamation

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 must 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 forests of Camellia oleifera is the lack of fertilizers, combined with repeated reclamation, and adding fertilizers, can greatly increase the output of Camellia oleifera. Organic fertilizer is the mainstay in the new year, and nitrogen fertilizer is used in the young year. 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, and the prevention and control of pests must be strengthened, efforts should be made to improve the ecological environment, and biochemical prevention and control methods should be adopted to solve the problems of pests and diseases.
