[0051] As a further technical scheme: the nutrient solution preparation method comprises the following steps:
[0052] The magnesium nitrate, calcium nitrate, potassium sulfate and water are uniformly mixed together, then heated to 60°C, kept stirring for 30min, and naturally cooled to room temperature, that is, it is obtained;
[0053] Described magnesium nitrate, calcium nitrate, potassium sulfate, water weight ratio is 14:12:12:100;
[0054] The spraying amount of the nutrient solution is 50kg / mu.
[0055] As a further technical scheme: the preparation method of the sodium maleate solution is:
[0056] Add sodium maleate and indole acetic acid to clear water in turn, and stir to obtain.
[0057] As a further technical scheme: the mass fraction of sodium maleate in the sodium maleate solution is 0.35%;
[0058] The mass fraction of indoleacetic acid was 0.2%.
[0059] The technical solutions of the embodiments of the present invention will be described clearly and comple...
Embodiment 1
[0061] A method for regulating and controlling oil content of Brassica napus, comprising the following steps:
[0062] (1) Seed treatment:
[0063] Before sowing, the seeds were sown for 2 days, and the seeds with full particles were screened, and the seeds were soaked in a seed soaking solution for 3 hours at a constant temperature, then filtered and drained naturally;
[0064] (2) Sowing and fertilizing:
[0065] After the seeds are sown, the pig manure-based fermented fertilizer is applied at the same time, and then the film is covered, and after germination, the covered film is uncovered;
[0066] (3) Flowering treatment:
[0067] When flowering for 5 days, the surface of rapeseed was sprayed with nutrient solution, sprayed once every 3 days, and sprayed three times in a row;
[0068] (4) Silique development period:
[0069] During the silique development period, the rapeseed was sprayed with sodium maleate solution every day for 2 consecutive sprays with an interval o...

[0089] (2) Sowing and fertilizing:
[0090] After the seeds are sown, the pig manure-based fermented fertilizer is applied at the same time, and then covered with a film, and after germination, the covered film is uncovered;
[0091] (3) Flowering treatment:
[0092] When flowering for 7 days, the surface of rapeseed was sprayed with nutrient solution, sprayed once every 3 days, and sprayed three times in a row;
[0093] (4) Silique development period:
[0094] During the silique development period, the rapeseed was sprayed with sodium maleate solution every day for 2 consecutive sprays with an interval of 5 days.
