Effects Of Density And Non Super-high Yield And Quality Of Two What Varieties With Different Spike Type

In the predecessor about the different type of spide quality and output research foundation,take the field test as the basis,has studied the N fertilizer and the density mutually opposes the different type of spide high production wheat the output and quality effect.The findings show that:1.The density,N fertilizer applied ratio have the important influence on the different spike type output and quality of wheat.Speaking of many spike of varieties,reduces the base nitrogen amount used,increasing pursueed the nitrogen proportion,the density is moderate,between its spike number ratio,numbers of seeds,the weight of a thousand seeds display the coordination,the output obvious increase;speaking of the big spide type,increases pursues the nitrogen proportion,the output the different density,the N fertilizer base pursues the proportion differently;heavy applied base N, pursues the nitrogen few,the high density,is advantageous in coordinates the big ear of variety output constitution,the output is high.Varieties spike type wheat are suitable the density is 200,000 basic seedling/667m~2heat is suitable the density is 300,000 basic seedling/667m~2,the N fertilizer base pursues compared to grasping in 7:3 about for suitable.Two kind of ear of wheat's wet gluten content and the subsidence value increase along with the density reduce,the Yannong 19 wet gluten content reduce the scope is most greatly 8%,Nongda 0068 reduces largest scale is 8.1%,two kind of ear of wheat's wet gluten content and the subsidence value increases the change rule along with the density to be consistent,not remarkable difference.The Yannong 19 subsidence values reduce the scope is most greatly 3.9%, Nongda 0068 is 3.3%,compares the Yannong 19 ranges of variation to be small, many ear of wheat subsidence value is big the ear to be slightly small the density influence.Forms the time,the settling time increases along with the density presents the rise the tendency,the Yannong 19 forms the time rise scope is 1.03～2.37min,the settling time is 0.09～2.41min;Nongda 0068 forms the time rise scope is 0.63～1.24%,the settling time is 0.29～1.41%;Compares the Yannong 19 scopes to be small.2.The nensity,N fertilizer applied ratio have important influence to different spike type community quality of wheat.When the N fertilizer same applied ratio,the density increases,the stem tiller number increases,the leaf area index increases,a high markup,does the material accumulation to increase,the density is same,the nitrogenous fertilizer base pursues the proportion the influence which to the stem tiller tendency,the leaf area index,high,the dry material accumulates to be big, under the different density condition,the N fertilizer base pursues the proportion not to be inconsistent to the different ear of wheat community structure target influence rule.The density,the N fertilizer base pursues the proportion to the smoke agriculture 19 stem tiller tendency,the leaf area index,high,community structures and so on dry material accumulation has the important influence,the density and the nitrogenous fertilizer base pursues between the proportion to exist makes the effect mutually.When in which by density 300,000 basic seedling/667m~2,the base pursues proportion 5:5 processing the dry material accumulation quantity to be highest,the mature period does the material accumulation quantity to achieve 18480.16kg/hm~2. The density,N fertilizer base pursues the proportion high to the Nongda 0068 stem tiller tendency,the leaf area index,community structures and so on dry material accumulation has the important influence;When the nitrogenous fertilizer base pursues the proportion same,the density increases,the stem tiller number increases, the leaf area index increases,reduces high,does the material accumulation to increase. the same density,the base pursues the proportion the influence which to the stem tiller tendency,the leaf area index,high,the dry material accumulates to be big,under the different density condition,the base pursues the proportion not to be inconsistent to the Nongda 0068 community structure target influence rule,the density and the nitrogenous fertilizer base pursues when between the proportion exists makes the effect mutually,Nongda 0068 by density 300,000 basic seedling/667m~2,the base pursues proportion 5:5 processing the dry material accumulation quantity to be highest,the mature period does the material accumulation quantity to achieve 18983.32kg/hm~2.3.The density,N fertilizer applied ratio have influence on different spike type flag leaf of wheat senile target.Under the same density condition,the increase pursues nitrogen proportion processing(base to pursue proportion 5:5 and 7:3) is advantageous in the postponement flag leaf is senile,the same base pursues under the proportion condition,reduces density processing(density 200,000 basic seedling /667m2 and low density 100,000 basic seedling/667m~2) is advantageous in the postponement flag leaf is senile;The different density,the base pursues the proportion senile and the output influence rule is inconsistent to the flag leaf,the density,the nitrogenous fertilizer base pursues the proportion senile and the output has the important control action to the Yannong 19 flag leaves,also the density and the N fertilizer base pursues between the proportion to exist makes the effect mutually. Reduces the density,the suitable increase topdressing proportion is advantageous in the postponement flag leaf is senile,when density 300,000 basic seedling/667m~2,the base pursue proportion 5:5 processing the output to be highest,reach 7694.19kg/hm~2, this output pursues proportion processing with other 8 bases the output difference to achieve remarkable level,this is because its community is big,the energy of light and the fertilizer can use fully.The experiment indicated that,the density,the N fertilizer base pursues the proportion to the Nongda 0068 chlorophyll content,the ultra oxygen mutase,the peroxide enzyme,the third dial and so on the senile target and the output has the remarkable control action.The different nitrogenous fertilizer base pursues proportion processing the senile advancement to be different,is advantageous is senile in the postponement flag leaf;The density,the nitrogenous fertilizer base pursues the proportion not to be inconsistent to the flag leaf senile influence rule,the density and the nitrogenous fertilizer base pursues between the proportion to exist makes the effect mutually.
