The controlled-release fertilizer for the sugarcane comprises the following raw materials by weight: 60 to 140 parts of a packaging material and 180 to 1200 parts of fertilizer granules. The controlled-release fertilizer for the sugarcane is prepared by comprising the steps of mixing, stirring, granulating, drying, cooling, packaging, etc. According to the invention, controlled-release rate of the fertilizer is moderate and stable; nutrition is balanced; the loss rate of the fertilizer can be effectively reduced; utilization efficiency of the fertilizer is improved; rapid and healthy growth of the sugarcane is promoted; and the yield of the sugarcane is increased by 12.4% to 13.6%, and the content of sucrose is increased by 0.32% to 0.4%.
Description
[technical field]
The invention belongs to fertilizer preparing technical field, be specifically related to a kind of sugarcane controlled-release fertilizer and preparation method thereof.
[background technology]
Sugarcane is important product sugar, particularly large in China's Guangxi province cultivated area, year sucrose yield account for about 70% of the total output of sugar in the whole nation.But there is in sugarcane production process the large feature of fertile part consumption, and single fertilization amount can not be too much, and fertilizer then can cause " burning root " phenomenon, therefore usually adopts a small amount of fertilizing method repeatedly to apply fertilizer.
At present someone begins one's study sugarcane fertilizer.Such as, patent documentation (patent No.: ZL200710066326.4) discloses a kind of special compound fertilizer for sugar-cane, comprise base manure and topdress, wherein in base manure, the ratio of N P and K and zinc is 10:10:8:0.5, and the ratio of the middle N P and K that topdresses is 18:6:4, but after above Term Fertilization, especially after southern rain-belt is used, wherein soluble inorganic fertilizer can faster dissolve, and reduces the effect of Term Fertilization on the one hand, cause fertilizer to waste, also pollute surrounding body in addition.For this reason, people is had to prepare slowly-releasing (controlled release) fertilizer by the mode increasing coating at fertilizer surface.Such as, patent documentation (patent No.: ZL96105688.6) discloses a kind of coated fertilizer, wherein the composition of soil layer is except 0.1-50 part gelatin, mainly soluble inorganic salt, as 1-180 part solubilizing agent, (its main component is ammonium sulfate, the inorganic salt such as ammonium nitrate) and 0.1-200 part plant nutrient compound (mainly iron, the vitriol of zinc), cause like this and have great amount of soluble inorganic salt in the coating of gelatin parcel, dissolving rapidly after meeting water makes fertiliser granulates form vesicular or disintegration, actual slowly-releasing (controlled release) ability is very limited.Therefore developing the moderate and stable fertilizer of a kind of controlled release rate is development trend.
