Abstract

The invention belongs to the technical field of rape cultivation, and particularly relates to a method for increasing the oil content of Brassica napus rapeseeds and improving lodging resistance simultaneously and application of the method. According to the method, in the early stage of the stem elongation period of Brassica napus rapes, the bolting height is 8-12 cm, a liquid silicon fertilizer aqueous solution with the monosilicic acid content being 0.086-0.101g.L<-1> is used between December 20th to January 20th next year in Gregorian calendar time, and the oil content of the Brassica napus rapeseeds is increased and lodging resistance is improved simultaneously. The method is applicable to Brassica napus rape varieties in rape production areas in the Yangtze river basin. By means of the method, the oil content is increased and lodging resistance is improved simultaneously under the condition that the yield of the Brassica napus rapes is higher through high-nitrogen culture, so that quality of the rapes is improved easily, application and popularization of the mechanical harvesting technology are facilitated, and economic benefits of rape production are improved.

Description

technical field

[0001] The invention belongs to the technical field of rape cultivation, and in particular relates to a method for simultaneously improving the oil content and lodging resistance of rapeseed rape seeds and its application. Background technique

[0002] Rapeseed oil is one of the main oil crops in my country. The content of saturated fatty acids, cholesterol and other unfavorable components in rapeseed oil is low, and it contains unique natural antioxidant components, namely rapeseed polyphenols. Long-term consumption can reduce cholesterol and prevent aging. .

[0003] Increasing nitrogen fertilizer application can significantly increase yield, but at present, due to the pure pursuit of yield, farmers often apply excessive nitrogen fertilizer, which reduces the oil content of rapeseed and affects the oil yield. At the same time, excessive application of nitrogen fertilizer will make the plants grow leggy, the ventilation and light transmittance of the colony ...
