On Water And Fertilizer Coupling On Yield And Quality Of Millet

In order to study the effect of water and fertilizer factors on grain Yield and quality of foxtail millet, this experiment use Nongda10 as the research object, using the quadratic general rotary design, with soil water content, nitrogen fertilizer, phosphate fertilizer, potash fertilizer as independent variables, BY millet Yield components、spike、grain number, grain weight and protein content were studied. The results are as follows:1. This study showed that the corn Yield and spike, grain number, grain weigh were very significant positive correlation. The correlation coefficient is 0.96、0.96、0.61 in turn. Compared by the correlation coefficient and the relevance of millet production from big to small in turn as follows:spike> grain number> grain Yield.2. The impact of fertilizer on millet Yield factor. This experimental study show that the absolute value of an item from the regression equation, the influence of impact factors on corn Yield of phosphorus> nitrogen> potassium> soil moisture. Soil moisture content and N application rate exist significant interaction, and with a positive interaction effect. The effect of nitrogen and phosphorus of interactions on millet production also had a significant impact. And nitrogen and phosphorus against each millet produced positive interaction. The impact of phosphorus and potassium against each millet Yield reached extremely significant level, the influence of phosphorus and potassium on corn Yield was also positive effect.3. On basis of factor influence on millet panicles. This experimental study showed that soil water content, nitrogen, potassium and soil moisture content interactions and the amount of nitrogen and potash against each corn ear Numbers have a significant impact. BY the absolute value of an item of the coefficient of regression equation can be concluded that the influence of various factors on the corn ear number was:soil moisture> nitrogen amount. It can be seen by the interactions of the absolute value of coefficient, soil water content and the amount of potassium application interactions> N application rate and the amount of potassium application interactions.4. The grain number and millet production also has significant positive correlation, the correlation coefficient reaches 0.61. Single factor levels nitrogen and phosphorus levels on the influence of the spike grain number reached extremely significant level. Soil moisture content of corn ear grain number reached significant level, the influence of N and P levels reached significant level, the interaction of N and K levels interaction reached significant level. Factors ear of corn grain number as follows:N>P>soil moisture content> K.5. The grain of millet and millet were very significant positive correlation, the output of the correlation coefficient of 0.57. Nitrogen and potassium levels system influence on millet grain reached extremely significant level. Influence factors on the influence of millet grain in order for N> K> P> soil water content. Phosphorus and potassium interaction and the interaction of nitrogen and potassium on the impact of millet grain reached extremely significant level.6. The crude protein content in corn millet quality evaluation was an important indicator, this experimental study showed that soil water content and nitrogen levels on the crude protein content of the millet produced significant influence, phosphorus and potassium interaction and interaction of nitrogen and phosphorus of foxtail millet protein achieves very significant level, the influence of soil water content and nitrogen interaction effect on the crude protein content in corn reached significant level. Influence factors on the influence of the crude protein content in corn respectively the soil moisture content was soil water content>N>K> P...
