The rice long-acting nitrogen fertilizer applicable to the low-temperature cold region has the beneficial effects that the validity of the nitrogen fertilizer is prolonged, the utilization rate is improved, temperatures of soil and a water layer can be obviously improved after the rice long-acting nitrogen fertilizer is applied, and good low-temperature resistance and rice seedling rapid growth promotion effect in a rice seedling stage can be realized.
Description
Technical field
The present invention relates to a kind of chemical fertilizer, in particular to a kind of paddy rice long-acting nitrogen fertilizer being applicable to low temperature Han Qu.
Background technology
Low temperature Han Qu in latitude district or high altitude localities higher, as northeast and the Northwest of China.At low temperature Han Qu because accumulated temperature is less, be generally 1 year one season of plantation.China waits low temperature district's Monitoring of Paddy Rice Plant Area of trembling with fear day by day to become large at present northeastward, these Soils In The Regions are fertile, rain hot same season, prepartion of land, be applicable to implant mass paddy rice.But in the paddy fields of low temperature Han Qu, except there is the problems such as the loss that summer, chemical fertilizer caused due to reasons such as rainwater are many, temperature is high is serious, utilization ratio is low, also exist when planting spring, the problem of nutrient removal and paddy growth is unfavorable for because temperature is lower, if delay implantation time, subject to frost damage time then in the fall, this point becomes restriction low temperature and to tremble with fear the principal element of district's paddy growth and output.At present except adopting the required accumulated temperature kind that production phase is shorter less, the good production means and method is not had to go to overcome this limiting factor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of paddy rice long-acting nitrogen fertilizer being applicable to low temperature Han Qu, this paddy rice long-acting nitrogen fertilizer can extend the fertilizer effectiveness phase, improve utilization rate of nitrogen fertilizer, more effectively can improve the temperature of soil and water layer in rice terrace after being manured into soil, be beneficial to rice seedling growth.
To achieve these goals, the present invention takes following technical scheme:
A kind of paddy rice long-acting nitrogen fertilizer being applicable to low temperature Han Qu, be made up by weight ratio of following raw material: 3,4-dimethyl pyrazole phosphoric acid salt 1.5 ~ 2 parts, Ulmic acids 250 ~ 300 parts, 400 ~ 500 parts, sulfuric acid, 350 ~ 400 parts, bicarbonate of ammonia, 500 ~ 550 parts, urea, 80 ~ 100 parts, nitrocalcite.
Preferably, the weight proportion of described raw material is: 3,4-dimethyl pyrazole phosphoric acid salt 1.8 parts, Ulmic acids 280 parts, 450 parts, sulfuric acid, 430 parts, bicarbonate of ammonia, 520 parts, urea, 90 parts, nitrocalcite.
The above-mentioned paddy rice long-acting nitrogen fertilizer being applicable to low temperature Han Qu is prepared as by the following method: first the Ulmic acids of described weight is crushed to more than 500 orders, urea is crushed to more than 200 orders; Then react in reactor Ulmic acids being joined the sulfuric acid that described weight is housed, after reaction terminating, urea is joined in reactor and continue reaction; Add the water that weight is mixture weight 20% in reactor after reaction terminating, after being cooled to room temperature, the bicarbonate of ammonia of described weight is joined in reactor and continue reaction; After reaction terminating, the nitrocalcite of described weight and 3,4-dimethyl pyrazole phosphoric acid salt are joined reactor, after stirring, material is imported granulator granulation and namely obtain the paddy rice long-acting nitrogen fertilizer that this is applicable to low temperature Han Qu.
Originally the paddy rice long-acting nitrogen fertilizer being applicable to low temperature Han Qu has following advantage: 1, the present invention utilizes sulfuric acid and tailing Ulmic acids to react, reduce Ulmic acids molecular weight, improve it active, fineness simultaneously more than 500 orders is also conducive to rapid diffusion in water body, one deck black layer can be formed bottom rice terrace water layer after being manured into soil, improve the absorption to sun power, effectively can improve the temperature of upper soll layer and water layer, for the quick growth of rice seedling provides more suitably temperature condition; The growing environment of rice seedling can be adjusted to micro-acid environment by the ureasulfuric acid that 2, this product contains, coordinate the nitric nitrogen that this product contains to promote that the seedling stage of paddy rice grows and tillers better simultaneously, reduce the pH of rice seedlings rhizosphere soil, the nutritive elements such as the phosphorus in activating soil simultaneously; 3, ureasulfuric acid slowly decomposes in paddy field, reduce the hydrolysis rate of urea, 3,4-dimethyl pyrazole phosphoric acid salt reduces the activity of nitrite bacteria, reduces nitrogen loss, and both synergies improve utilization ratio and the working lipe of nitrogen nutrient, decrease topdressing of later stage, save artificial, and the later stage is not de-fertile, improves output.This paddy rice long-acting nitrogen fertilizer production technique being applicable to low temperature Han Qu is simple, without the need to processing sequence and the expensive machine of complexity, is convenient to promote.
