How to manage the flowering of rape? Please introduce the management of rape flowers during flowering with reference to the following methods: first, control aphids and foliar spraying boron fertilizer. At present, the prevention and control of aphids is beneficial to field operation and effectively control the damage of aphids to rape in the later stage. "Lesben", Jin Haonian, etc., which have stomach toxicity, contact or fumigation, should be sprayed with a bucket of water and a "Zhonglong boron" micro-fertilizer containing 10% boron. Spraying liquid should be uniform and comprehensive in order to achieve good control effect. Second, after rape enters the early flowering stage, the demand for water and fertilizer increases continuously. irrigation at the early flowering stage can not only meet the water requirements before and after the full flowering stage of rape, but also effectively control or avoid rape lodging. Due to uneven fertility in some fields, rape with poor management, such as lack of fertilizer or uneven growth, can be properly supplemented with balanced fertilizer combined with irrigation.
