Please guide the cultivation of rape fertilizer should pay attention to the following three points: first, do not apply fertilizer hole fertilizer is easy to cause local fertilizer concentration is too high, resulting in root system can not be evenly absorbed, and even cause rape poisoning, root burning, affecting growth, especially ammonium bicarbonate. So rape fertilization is the most.

What should be paid attention to when applying fertilizer to rape? Please guide the cultivation of rape fertilizer should pay attention to the following three points: first, do not apply fertilizer hole fertilizer is easy to cause local fertilizer concentration is too high, resulting in root system can not be evenly absorbed, and even cause rape poisoning, root burning, affecting growth, especially ammonium bicarbonate. Therefore, rape fertilization is best to be ditched between rape rows, which is generally 10 cm deep and 20 cm wide. Second, do not apply seedling fertilizer late. Some farmers apply some farm manure as seedling fertilizer only two months after transplanting live rape. In fact, rape needs to absorb more nutrients from the field at this time, if the nutrition can not keep up with it, it will affect the growth of rape and form "rigid seedlings". For this reason, when transplanting rape, it is necessary to use rare human feces and urine to irrigate rape fixed root water. after living trees, 250 kilograms of human feces and 500 kilograms of urea are added to 2 kilograms of urea and 1000 kilograms to 1500 kilograms of water to benefit strong seedlings. Third, do not ignore boron fertilizer application rape is sensitive to boron fertilizer, boron deficiency will cause physiological diseases, lead to poor root development, only flowering is not fruiting or grain is not full. Generally, 0.2-0.3 kg borax is used as base fertilizer per mu. At the same time, boron fertilizer was sprayed once in rape seedling stage, bud bolting stage and flowering stage, with 50 grams of borax per mu and 50 kilograms of water spray.
