Embodiment 1

[0011] Using potted Brassica oleracea under natural conditions as material, check the local weather forecast to ensure that there is no rain within 24 hours when the method is implemented. Spray the siliques of Brassica napus 6 days after flowering with a mixed solution containing 10 mg / L phthalimide and 1.0 g / L Tween 80 after thorough mixing. After 5 days, repeat the above method once.

[0012] After the black seed rape material treated by this method is mature, the oil content of the seed is significantly increased by 6%.

Embodiment 2

[0014] Using potted Brassica oleracea under natural conditions as material, check the local weather forecast to ensure that there is no rain within 24 hours when the method is implemented. Spray the siliques of Brassica napus 10 days after flowering with a mixed solution containing 15 mg / L phthalimide and 0.5 g / L Tween 80 after thorough mixing. After 3 days, repeat the above method once.

[0015] After the black seed rape material treated by this method is mature, the oil content of the seed is significantly increased by 8%.

Embodiment 3

[0017] Using potted mustard type black seed rape under natural conditions as material, check the local weather forecast to ensure that there is no rain within 24 hours when the method is implemented. Spray the siliques of Brassica napus 6 days after flowering with a mixed solution containing 15 mg / L phthalimide and 0.5 g / L Tween 80 after thorough mixing. After 5 days, repeat the above method once.

[0018] The oil content of the black seed rape material treated by this method is significantly increased by 5% after the seeds mature.

Abstract

The invention relates to a regulation and control method for improving the oil content of black-seeded rape. According to the method, local weather forecasts are checked, and it is guaranteed that atleast 24 hours after the method is implemented, it does not rain; a fully-mixed solution which contains 10-15 mg / L of phthalimide and 0.5-1.0 g / L of Tween 80 is used for spraying siliques of the black-seeded rape 6-10 days after plants bloom; after 3-5 days, the method is repeated once. According to black-seeded rape material treated through the method, after seeds are mature, the oil content of the black-seeded rape seeds is significantly improved by 4-8%.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a method for regulating the oil content of rapeseed by using chemical substances in the growth process of rapeseed. Background technique [0002] Increasing the oil content of rapeseed has always been a hot spot in rapeseed breeding. Breeders have bred many varieties with high oil content by means of distant hybridization, chemical mutagenesis and biotechnology. The study found that the oil content of the same variety changed significantly under different cultivation conditions. Studies have shown that increasing the application of nitrogen fertilizer can increase the protein content of seeds and relatively reduce the oil content of rapeseed; the application of nitrogen fertilizer at different development stages also has an impact on the oil content, the later the fertilization is, the lower the oil content of the seeds; under the condition of phosphorus deficiency, increasing the...
