Description
Technical Field
The invention belongs to the technical field of fertilizers, and particularly relates to a special compound fertilizer for increasing the yield of rapeseed.
Background
Rape is a main oil crop in China, provides more than half of edible oil in China, and is a potential bulk protein source for feeding next to soybean meal. Rape production has important influence on ensuring the supply of edible vegetable oil and protein for feeding, improving food structure and promoting the development of breeding industry and processing industry in China. Meanwhile, the rape is a crop combining land utilization and soil cultivation, plays an important role in protecting and even improving soil fertility and controlling soil-borne diseases when being planted, and is one of important factors for promoting the sustainable development of agriculture in China.
The annual rape planting area of China is about 800 hectare, the yield per unit of rapeseeds is greatly different from the main rape producing countries of Germany, France and other European rapeseeds due to the inexistent dispersed planting and matched cultivation technology, and the quality of the rapeseeds is also greatly different from that of the rapeseeds in Canada and Australia with the same yield level. In the rape cultivation management technology, reasonable fertilization is one of the important technical links. The investigation shows that the following problems exist in the management of the rape fertilizer: (1) the blindness and the randomness of the fertilization are high, the effect of the input fertilizer is poor, and the utilization rate of the fertilizer is low. (2) The fertilizer dosage is low, the proportion of nutrients is not coordinated, and the fertilizer is represented as a diazo phosphate fertilizer, a light potassium fertilizer, a medium-trace element fertilizer and a trace element fertilizer, so that the imbalance of soil nutrients is increased. In the field production of rape, the input of nitrogen, phosphorus and potassium is unbalanced, such as the rape seed in Hubei provinceNitrogen (N) and phosphorus (P) at present in producing area2O5) Potassium (K)2O) is applied at a ratio of 1: 0.47: 0.31, which is quite different from the 1: 0.6: 0.9 required by the crop. Meanwhile, trace element fertilizers such as boron and the like have many problems in application. (3) The special formula for rape and the special formula fertilizer are less in application, and the industrialization of the fertilizer application starts slowly.
