Embodiment Construction
[0019] Exemplary embodiments of the present invention are described in detail below. The description of the exemplary embodiments is for the purpose of illustration only, and in no way limits the invention and its application or usage.
[0020] The invention provides an improved sorghum-specific controlled-release fertilizer. The sorghum-specific controlled-release fertilizer includes nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, sulfur fertilizer, zinc fertilizer and iron fertilizer. The sorghum-specific controlled-release fertilizer may also include a soil conditioner. In the special controlled-release fertilizer for sorghum according to the present invention, the parts by weight of various effective chemical elements are: 260-280 parts of ordinary urea, 185-215 parts of controlled-release nitrogen fertilizer, and 200-230 parts of potassium sulfate , 130 to 150 parts of monoammonium phosphate, 20 to 30 parts of ammonium sulfate, 25 to 35 parts of zinc sul...

The invention relates to controlled-release fertilizer special for sorghum. The controlled-release fertilizer comprises nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, sulfur fertilizer, zinc fertilizer and iron fertilizer. In the controlled-release fertilizer special for sorghum, effective chemical elements include, by weight of pure nutrients, 23-25% of nitrogen, 8-10% of phosphorus pentoxide, 12-14% of potassium oxide, 0.41-0.82% of sulfur, 0.4-0.7% of iron, 0.4-0.8% of zinc and 7-9% of humic acid, wherein the nitrogen fertilizer includes controlled-release nitrogen fertilizer, and the content of the nitrogen in the controlled-release nitrogen fertilizer is 32-39% of the total content of the nitrogen in the nitrogen fertilizer. The controlled-release fertilizer has theadvantages that the ratio of fertilizer nutrients is reasonable and accords with the nutrient demand of the whole growth period of the sorghum, the fertilizer utilization rate is high, and the input and labor costs for top dressing are saved; appropriate amounts of the iron fertilizer and the zinc fertilizer are added, so that the foundation is laid for the improvement of sorghum quality and economic benefits.
Description
technical field [0001] The invention relates to a controlled-release fertilizer, in particular to a special controlled-release fertilizer for sorghum suitable for simultaneous sowing of seed and fertilizer. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Sorghum has multiple stress resistances such as drought resistance, waterlogging tolerance, salt-alkali tolerance, and barrenness tolerance, and occupies an important position in the world's grains. It is not only a food and fodder crop, but also the main raw material for wine making. Sorghum has strong adaptability, fast growth, sensitive response to nutrients, fast absorption of nutrients, and good stability. It can absorb soil nutrients at a high intensity under the condition of high density planting, and can achieve nutrient depletion absorption in a short...
