Coupling Effects Of Density And Fertilizer On Yield And Quality Of High Gluten Spring Wheat

This study belongs to a section of Heilongjiang Regional Great Specific Planning Programs:production technology and industrialization program for good quality and high efficiency of wheat in Heilongjiang reclamation region. The experiments were carried out in agricultural scientific research institute of Hei Long Jiang August First Land Reclamation University in Mi-shan county in 2006. Strong muscle wheat Longmai-26 was used as experimental varieties, to study the effect of seeding rates and different fertilization on the morphological characters, the quality and yield of spring wheat by using the design of two factors randomized blocks experiment methods. The results were as follows:1.The increase of fertilizer regulate effectively the height of wheat, the interaction of fertilizer and density benefit for molding ideal construction of wheat, promote the growth of the spike.2. Low density and high fertilizer benefit for the accumulation of dry matter from those of aerial parts of wheat. Lower density and higher fertilizer much benefit for the synthesize of chlorophyll, increase leaf area duration, get more the weight of spike. In comparison with the fertilizer, by increasing the grains of spike, sparse planting much promote the increase of the yield of per plant.3. Density of high protein is also high content of wet gluten. Fertilizer and density for promoting test weight are benefit for accumulation of starch, however is not benefit for the formation of protein. The combination of the fitting fertilizer and density can get much sedimentation value and falling number.4. More fertilizer and medium density of population are benefit for improving the characteristic of formation, stability and extend of paste.5. Taking it all round, we consider that 4.5 million stub per hundred-meter square, apply 90kg fertilizer, 9 million stub per hundred-meter square, apply 90kg and 6 million stub per hundred-meter square, apply 180kg, are better combination, it is suggest the density of 6 million stub per hundred-meter square should apply 180kg fertilizer in ecological area of the experiment area for Longmai 26.
