Abstract
The invention discloses a kind of Slow-release fertilizer special for soybean, it is characterized in that being made up of the raw material of following weight part: urea 10-12, Repone K 8-10, tobacco leaf slag 3-5, diammonium phosphate 5-8, bicarbonate of ammonia 15-18, copper sulfate 1-2, Sodium Selenite 1-2, ferrous sulfate 1-2, ammonium molybdate 1-2, used oil 2-3, chromium chloride 0.1-0.2, poly aspartic acid 1-2, weathered coal 5-8, celestite powder 2-3, polyvinyl alcohol 1-2.Nutritive element needed for reasonable disposition soybeans they grow of the present invention, single-dose application, need not topdress, and fertilizer release is slow, meets soybeans they grow needs, improves soybean yields, reduces fertilizer application frequency, reduces fertilizer amount, reduces production cost.Used oil coating of the present invention, realizes fertilizer slow release, after polyvinyl alcohol mixes with lazurite, can form a housing, make fertilizer element slow releasing at fertilizer.
Description
Technical field
The present invention relates to slow release fertilizer field, is exactly a kind of Slow-release fertilizer special for soybean.
Background technology
Soybean is also used as food and the existing history in 5000 of medicine in Chinese cultivated, introduces the U.S. in 1804; 20 middle of century, become important crops at southern US and Midwest.Soybean is the most being rich in nutrition in leguminous plants and is easy to the food of digestion, is protein the most cheap the abundantest source.Today in the world many places be the Major Foods of humans and animals.Soybean planting is very high to fertilizer nutrient, fertilizer Different Effects output, and existing fertilizer needs repeatedly to apply fertilizer, topdress, and cost is high.
Summary of the invention
The object of the present invention is to provide one can increase yield
slow-release fertilizer special for soybean and preparation method thereof, single-dose application, need not topdress, and fertilizer release is slow, meets soybeans they grow needs, improves soybean yields, reduces fertilizer application frequency, reduces fertilizer amount, reduces production cost.
Above-mentioned purpose is realized by following scheme:
slow-release fertilizer special for soybean, is characterized in that being made up of the raw material of following weight part:urea 10-12, Repone K 8-10, tobacco leaf slag 3-5, diammonium phosphate 5-8, bicarbonate of ammonia 15-18, copper sulfate 1-2, Sodium Selenite 1-2, ferrous sulfate 1-2, ammonium molybdate 1-2, used oil 2-3, chromium chloride 0.1-0.2, poly aspartic acid 1-2, weathered coal 5-8, celestite powder 2-3, polyvinyl alcohol 1-2.
the preparation method of Slow-release fertilizer special for soybean, is characterized in that comprising the following steps:
(1), by copper sulfate, Sodium Selenite, ferrous sulfate, ammonium molybdate, used oil, chromium chloride, poly aspartic acid, weathered coal mixing, granulation;
(2), other leftover materials are mixed;
(3), by step (1), (2) gained mixing of materials;
(4), by polyvinyl alcohol heating water dissolve, add celestite powder, stir into pasty state; Add in step (3) material, stir, granulation.
Beneficial effect of the present invention is:
nutritive element needed for reasonable disposition soybeans they grow of the present invention, single-dose application, need not topdress, and fertilizer release is slow, meets soybeans they grow needs, improves soybean yields, reduces fertilizer application frequency, reduces fertilizer amount, reduces production cost.Used oil coating of the present invention, realizes fertilizer slow release, after polyvinyl alcohol mixes with lazurite, can form a housing, make fertilizer element slow releasing at fertilizer.
Embodiment
slow-release fertilizer special for soybean, be made up of the raw material of following weight part (kilogram):urea 10, Repone K 10, tobacco leaf slag 5, diammonium phosphate 8, bicarbonate of ammonia 18, copper sulfate 2, Sodium Selenite 2, ferrous sulfate 1, ammonium molybdate 1, used oil 2, chromium chloride 0.2, poly aspartic acid 2, weathered coal 5, celestite powder 3, polyvinyl alcohol 1.
the preparation method of Slow-release fertilizer special for soybean, comprises the following steps:
(1), by copper sulfate, Sodium Selenite, ferrous sulfate, ammonium molybdate, used oil, chromium chloride, poly aspartic acid, weathered coal mixing, granulation;
(2), other leftover materials are mixed;
(3), by step (1), (2) gained mixing of materials;
(4), by polyvinyl alcohol heating water dissolve, add celestite powder, stir into pasty state; Add in step (3) material, stir, granulation.
Application test shows to use the fertilizer special for soybeans ratio of the present embodiment to use general every mu, the nitrogenous fertilizer soybean yield-increasing 22% of equivalent.
Carry out native fish experiment to the present embodiment, the present embodiment 24 hour initial stage nutrient release rate is 6.23%, and comparative group Common compound fertilizer is 33.26%, and therefore the present embodiment has obvious slow releasing function.
