Abstract
The invention discloses a polymer-sulfur double coated humic acid sustained and controlled-release fertilizer dedicated for wheat, and is characterized in that the ingredients of the fertilizer comprises: 10-40 parts by weight of urea, 90-110 parts by weight of polymer coated urea, 100-115 parts by weight of sulfur coated urea, 255-310 parts by weight of diammonium phosphate, 30-70 parts by weight of potassium chloride, 420-445 parts by weight of humic acid slow release composite fertilizer, and 10-20 parts by weight of zinc sulfate. Compared with the prior art, by using the nutrient release characteristics of the sulfur-polymer double coated fertilizer, and the controlled-release and synergy effects of the humic acid to nutrients, and simultaneously according to the nutrient uptake pattern, a complex formulation for producing the polymer-sulfur double coated humic acid sustained and controlled-release fertilizer dedicated for wheat is formed; and with a certain amount of trace elements, the nutrients are controlled to release slowly, ensuring good fertilization and uptake effects.
Description
Technical field
The invention belongs to slow/controlled release fertilizer technology field, specifically is a kind of two film humic acids slow-release or control-release fertilizers of the special-purpose sulfur and resin of wheat that are suitable for.
Background technology
China is the country that the wheat gross output is the highest in the world, consumption is maximum.The wheat planting area accounts for about 22% of China's food crop total area, and output accounts for more than 20% of total output of grain, is main food crop of China and important commodity food, strategic reserve grain kind, in grain-production, circulation and consumption, has critical role.Along with the raising of China's Increase of population and living standards of the people, the wheat demand constantly increases, and sets up wheat advantage district, development high-quality wheat special, to improve the wheat integrated production capacity, guarantee national food safely, meet the need of market significant.
Can significantly improve the output of wheat through scientific and reasonable fertilising, there are some researches show that balance fertilizing compares habits fertilization and can increase production 9.1%, can also coordinate soil nutrient, steadily improve soil fertility.Therefore in the cultivation of wheat, provide a kind of and can increase production, can improve again the long-acting slow-releasing and controlled-releasing of quality fertile very necessary.
Slow-release or control-release fertilizer not only can improve utilization rate of fertilizer, reduces wheat management manpower consumption.Humic acids has the good slow release performance and improves the soil, improves characteristics such as crop anti-adversity, and humic acids is applied in compound fertilizer and the slow-release or control-release fertilizer, can improve drought resisting, the lodging tolerance of wheat, and significantly improve output.
Summary of the invention
For addressing the above problem; The present invention provides a kind of two film humic acids slow-release or control-release fertilizers of the special-purpose sulfur and resin of wheat that are suitable for, and the present invention utilizes the Nutrient Release of sulphur, the two membrane envelope fertilizer of resin, and humic acids is to the sustained-release synergistic effect of nutrient; Law of nutritive absorption according to wheat carries out the two film humic acids slow-release or control-release fertilizers of the special-purpose sulfur and resin of composite production wheat simultaneously; And composite a certain amount of middle trace element, the slow control of nutrient is Ji mutually, guarantees good fertilising and assimilation effect.
For achieving the above object, the present invention adopts following technical scheme:
