Northern rape high-yield culture technique

Abstract

The present invention is one kind of high yield rape cultivating technology in Northern arean of China. The high yield rape cultivating technology includes: completing leveling land, fertilizing and ridge formation before winter; timely seeding; thinning out seedling; loosening soil and field management, preventing and killing aphid with pesticide; and timely harvest, drying in the air and threshing. The present invention adopts rape variety introduced from Canadan and with the characteristics of low sinapic acid and thioglycoside content. The rape has long blooming period and is excellent honey source plant.

Description

technical field

[0001] The invention belongs to the field of agricultural cultivation technology, and relates to a high-yield cultivation technology of northern rapeseed. Background technique

[0002] Rapeseed is an important oil crop. The oil content in the seeds accounts for 35-50% of the dry weight of the seeds. Rapeseed oil is a good edible vegetable oil, rich in fatty acids and multivitamins, and rich in nutrition. The cake after oil extraction contains about 40% protein, and its nutritional value is similar to that of soybean cake, so it is a good concentrate feed. Residual roots, stems, and shells can be returned to the field, which can significantly improve soil fertility. However, rape is a southern crop and is not suitable for cultivation in the cold northern regions. At present, rapeseed is planted in large areas in the south and southwest of my country, but in the north of my country, the yield is not high due to many reasons such as technology and climate, so ...
