油菜是四川主要油料作物,面积与总产都居全国第一,主要油菜的川西平原,由于日照不足,特别是开花期阴雨天较多,光合生产率低,影响油菜产量的进一步提高。选用新型植物生长促进剂,调节植物内部生理功能,增强光合作用,提高光合效率,增加干物质积累,是一项费省效宏的增产措施。为了给大面积推广应用“ EF”提供科学依据,应四川农科院科技处的安排,承担了“EF”对油菜的增产效果试验。
Rape is the major oilseed crop in Sichuan province with the largest area and total output in the country. The main rapeseed in the western Sichuan Plain is due to lack of sunshine, especially cloudy and rainy days at flowering stage, and low photosynthetic productivity, which further affects the yield of rapeseed. Selection of a new plant growth promoter, regulating plant internal physiological functions, enhance photosynthesis, improve photosynthetic efficiency and increase dry matter accumulation, is a cost-effective macro-stimulation measures. In order to provide a scientific basis for the popularization and application of “EF” in a large area, the experiment of “EF” on the yield increase of rapeseed should be taken at the arrangement of Science and Technology Department of Sichuan Academy of Agricultural Sciences.
