2.1 marine alga coated slow-release ureas are on the impact of corn yield
Table 1 corn yield and constituent element
As can be seen from Table 1, the grain number per spike that coated slow-release composite fertilizer processes comparatively common fertilizer exceeds 11, and tassel row number and 100-grain weight also increase to some extent, thus add corn yield.Compared with common fertilizer, there is obvious production-increasing function in coated slow-release composite fertilizer to corn, and U is than CK2 volume increase 43.72%.HU is than CK2 volume increase 44.91%.
2.2 marine alga coated slow-release ureas are on the impact of nitrogen utilization efficiency
Table 2 nitrogen utilization efficiency
As can be seen from Table 2, the nitrogen harvest index of HU process and the agronomy efficiency of nitrogenous fertilizer are all higher than U process, and this may be because marine alga coated slow-release urea promotes that photosynthate and nitrogen transport in seed, also has certain effect to raising corn kernel protein content.Coated slow-release composite fertilizer can significantly improve nitrogen utilization efficiency, brings up to 39.16% by 36.32%, and comparatively common fertilizer increases by 6.9%.
3. brief summary
Soil-column test result shows, the coated slow-release composite fertilizer that the present invention produces has the good effect that increases production and improves productivity, and its amount of increase in production comparatively common fertilizer exceeds 10.35 percentage points, and utilization rate of nitrogen fertilizer improves 6.8%.
Above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited in above-mentioned citing, and the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
