Application of Special Controlled Release Fertilizer in Direct-seeding of Rapeseeds

In the east of Hunan Province, the research introduced new-type special controlled-release fertilizer for rapeseed, "Yishizhuang", and explored its applications in direct-seeding of rapeseed production. The results showed that the application of special controlled release fertilizer for rapeseeds avoids early decline of rapeseed resulting from fertilizer loss by one-off application, improves the number of green leaf before winter, and extends photosynthetic lifespan of pods, which significantly increases yields. What's more, with higher output-input ratio, the fertilizer takes advantages in saving cost, labor and increasing yield.
