| Abstract: | This paper researched process which rape accelerated dry matter, regulation which nitrogen, phosphorus and potassium were needed, and their content in respective organ. To get 100kg seed, rape need to absorb nitrogen 9.48kg, phosphorus 3.61kg, potassium 8.89kg. The rate among them is 1:0.38:0.94, and this paper also researched proper quantity of potassium manure application, it is 135kg per hectare. |
| Keywords: | Rape Nutritional Character Potassium Manure Application |
