Selenium-rich quality-improving direct-seeding high-yield cultivation method for oilseed rape

Abstract

The invention discloses an experimental device for seed selection and cultivation of selenium-enriched rape. The experimental device comprises an experimental box body and is characterized in that a cultivation plate is fixedly connected to the inner wall of the experimental box body, a water permeable hole is formed in the top face of the cultivation plate in a penetrating mode, a partition plate is fixedly connected to the top face of the water permeable hole, the top face of the partition plate is fixedly connected with the top face of the inner wall of the experimental box body, an air control mechanism, a lighting lamp, a nutrient mechanism and a temperature control mechanism are arranged on the surface of the experimental box body, and a movable door is hinged to the front side of the experimental box body. During use, the effect of accurately controlling various growth conditions in the cultivation process is achieved, so that researchers can conveniently carry out variable control and contrast experiments, the workload of the researchers is effectively reduced, and compared with screening in a test field, the method is more convenient, and has good practicability, and the effect of conveniently and rapidly carrying and moving the device is achieved, so that the device is more flexible and convenient to use, and the practicability of the device is enhanced.

Description

technical field [0001] The invention belongs to the technical field of vegetable cultivation, and in particular relates to a selenium-enriched, quality-enriched, live-directed and high-yield cultivation method for rapeseed. Background technique [0002] Rapeseed is regarded as a selenium-accumulating plant, which can grow on soil with high selenium concentration, and can absorb and assimilate selenium from the soil environment. Increasing the supply of selenium in an appropriate amount can effectively promote the growth of rapeseed, enhance and maintain the strong physiological activity of rapeseed , increase the selenium content of rapeseed through selenium supplementation cultivation, and make full use of the green factory function of rapeseed to convert inorganic selenium into organic selenium. [0003] With the improvement of the level of agricultural modernization, the advantages of mechanical farming, machine sowing, and machine harvesting are highlighted. When farmers...

Problems solved by technology

[0003] With the improvement of the level of agricultural modernization, the advantages of mechanical farming, machine sowing, and machine harvesting are highlighted. When farmers grow rapeseed, although the planting area has increased, the yield is low and the economic benefits are not high. The reasons include late planting season and high planting density. , the ditch water is not smooth, and the technology is not mastered
