It showes that effect of potassium on physiology in rape and the physiologyical characters of quality rape, studies the effect of potassium fertilizer (K 2SO 4) on main characters and yield of quality rape, also studies the best application technique on potassium fertilizer in quality rape.
Nitrogen supplying is one of the key factors that can influence the grain yield and protein content of wheat.In the paper the advance in the application techniques of nitrogen fertilizer for improvement of both grain yield and protein content of wheat was briefly reviewed in four aspects of the amount, the stages and the ways of nitrogen application and the kind of nitrogen fertilizer.
The advanes in the application techniques of nitrogen fertilizer for improvement of both grain yield and protein content of wheat were brifly reviewed in three aspects of the determination of the amount of nitrogen application properly, nitrogen application at different stages and nitrogen application with other nutritional elements at home and abroad in the paper The framework application techniques of nitrogen fertilizer for improving both grain yield and protein concentration simultaneously were discussed The key problems that need to be investgated in the furture and its importance were also analysed
To research into the N application techniques for high quality and yield culture of malting barley effects of different nitrogen application on population quality,yield and grain protein content of malting barley Yangnongpi 2 were studied with reasonable P proportion during 2003—2004.The results showed that under the same condition of the ratio of base and panicle fertilizer,the ear number,leaf area index,dry matter accumulation,grain protein content increased as the increase of nitrogn application amount.
The fact that gas chromatography on glass capillary columns is far from being exploited to its full potential is due to two main reasons: widespread disappointment in poor quality columns and insufficient know-how in the application technique.
At various application techniques, the retardants suppressed growth of axial organs, promoted thickening and strengthening of lower internodes, and caused a considerable increase in ABA content.
We investigated efficacy and safety of different energy sources and application techniques for the treatment of atrial fibrillation in an experimental acute sheep model.
The elimination of problems inherent in the chemical nature of pine tannin extracts was obtained by already used industrial and laboratory "separate application" techniques.
The formulations and application techniques presented appear to be suitable for most of the more widely distributed pine species such us Pinus patula, P.
Exponential fertilization enhanced an increase in N concentration of the whole plant suggesting exponential delivery schedule is an efficient fertilization technique for greater nutrient uptake of plants.
