Three points of applying boron fertilizer in rapeseed
The first is to strictly control the amount of boron, although it is essential for the growth of rapeseed nutrients, but it is a trace element, must strictly control the amount of application, not the application of the more the better. If indiscriminate application of boron fertilizer, not only can not promote the growth and development of rape, but will have a serious inhibitory effect on rape seed germination, emergence, growth, resulting in "boron poisoning."
The second is to master the application of methods and timing of boron deficiency will cause rape to "flower but not real", so the best spraying boron effect during flowering. It is well known that boron is needed throughout the growth stage of rape, and it is generally preferable to spray boron on the foliage during the seedling stage and bud stage.
The third is to use high-quality boron fertilizer The current market for boron fertilizer products sold on the agricultural capital market has a wide range of products, ranging in quality and quality. Some boron fertilizers look the same as high-quality boron fertilizers, but in fact, the boron content is very small. Almost without boron. The application of unqualified boron fertilizer not only causes direct economic losses, but also has a serious impact on the growth and yield of rapeseed. Therefore, remind farmers to remember when buying boron fertilizer!
