On the basis of the winter management, the temperature gradually rises after the spring, which is the period when the rape grows long leaves and branches and the flower buds form abundantly. Therefore, strengthening the spring rape management is an important step to increase the output. Tillage and weeding Spring should pay close attention to the soil, especially after the rain land compaction, not timely soil, it will affect the growth of rapeseed. Late crop of rapeseed would have hardened soil, but also to fine hoe, keep the soil loose foam. Spring rape grows fast, the grass grows fast, so we should combine the early weeding. To catch late, oil seal closed line, it is not good hoe. Prevent frost damage Spring often has cold, should pay attention to prevent frost damage. First of all, to be more fertilizers, so that robust rape growth and improve cold hardiness; Second, loosening pocket, on the cold, anti-lodging are good; third, Shi
