Spraying boron fertilizer at the beginning of rapeseed

In general, the content of boron in cruciferous crops is higher than that of monocotyledonous crops. Generally, crops with high boron content also require a large amount of boron. Boron promotes the normal development of boring plants such as rapeseed, accelerates the germination of pollen and the elongation of pollen tubes, and is conducive to fertilization. In the absence of boron, these organs are likely to shrink, fall off, and appear to be physiologically diseased, such as "flowering and failing". Severely caused a significant reduction in rapeseed production. According to the test, rapeseed can increase production by more than 10% after spraying boron. At the beginning of April, the first flowering period of rapeseed is the best period for spraying boron fertilizer. 100 grams of borax is mixed with 50 kilograms of borax and sprayed together to prevent Sclerotinia sclerotiorum. It is best to spray it once every 7 to 10 days. Better.
