How to grow rape with high yield?It is necessary to transform the rapeseed land with low oil yield according to the actual situation, improve the structure of the stand and improve the land conditions in the first two cases, select the forest area with better land conditions in the third type, and renew the varieties of the forest land with development potential, and the forest land of the fourth type can be transformed according to the requirements of classified yield.
1.Improvement of soil conditions.
1) Repeated reclamation and deep reclamation have a significant effect on the growth and development of Camellia oleifera, and the yield is greatly improved. In the first winter of the first year of transformation, the entire land should be reclaimed to a depth of about 10 to 20 centimeters, and then it should be deeply turned once every two to three years, and when it is deeply turned, it should be combined with organic fertilizer to fertilize the canopy according to the requirements. It is also necessary to plough once a year in the summer, with a depth of about 10 centimeters, and when ploughing, the weeds should be removed, the soil should be loosened, and horizontal ladders should be made to achieve the purpose of protecting the soil, fertilizer and moisture.
2) One of the main reasons for increasing water and fertilizing the low-yield forest of Camellia oleifera is the lack of fertilizer, combined with repeated reclamation, and then increasing fertilizer, the yield of Camellia oleifera can be greatly improved. Fertilize the forest land according to the requirements of fertilizer.
3.Strengthen the prevention and control of pests and diseases, Camellia oleifera is easy to affect pests and diseases, the prevention and control of pests and diseases must be strengthened, and efforts should be made to improve the ecological environment, and the use of biochemical control methods to solve the problem of pests and diseases.
