The experiment forever the Yongfeng Town Wulong village will carry on 2006-2008 years in the Tianchang city Anhui Province.Selects High quality wheat variety about the wheat 12 and five agronomy factor with the output and quality related to the wheat,To research the influence about different cultivation measure to physiology ecology target,the output and the constitution factor and the main quality character of rice stubble wheat Yangmai 12.The main result is as follows:1 The influence about different cultivation measure to raises the shape targets and the certain physiological characteristic of wheat 12This test result indicated that the row spacing is not remarkable influence to the wheat stem tiller dynamic;The basic seedling is extremely remarkable influence to the wheat stem tiller dynamic.The base executes the nitrogen proportion 60%levels and the base executes between the nitrogen proportion 100%,80%levels to be remarkable to the wheat stem tiller dynamic influence phase difference,pursues the nitrogen maturity degree of young plants complement to survive the winter the stem tiller number and the highest stem tiller number influence difference is not remarkable,but is extremely remarkable to the effective Guangzhou number's influence difference.The maturity degree of young plants complement is 1 when the rate of tiller enhancement compares the maturity degree of young plants complement is 2 time higher than 5.06%.Therefore when the basic seedling is 2,250,000/hm~2 or3,000,000/hm~2,executes the nitrogen total quantity is the 300kg/hm~2 wheat comlnunity structure composition is quite reasonable;The base executes the nitrogen proportion is 60%,when the maturity degree of young plants complement is 1 pursues when executes 40%nitrogenous fertilizers,the wheat community structure composition achieves the optimum condition.In same applies fertilizer and the total quantity,the row spacing and the wheat chlorophyll content is smaller,Under the same density and the row spacing,along with applies fertilizer the tendency which increases the wheat leaf blade chlorophyll content and the soluble sugar content assumes increases,but the increase is small.The applies fertilizer about 300kg/hm~2 the chlorophyll content and the soluble sugar content are high.In same applies fertilizer quantity,base nitrogen proportion 60%,when pursues the nitrogen maturity degree of young plants complement is 1 supplements 40%nitrogenous fertilizers the chlorophyll content and the soluble sugar content the base executes the nitrogen proportion obviously when 100%must be higher.The wheat flag leaf photosynthesis speed increases along with applies fertilizer increases.The different base pursues the ratio to process is in turn the base pursues to the wheat various times photosynthesis speed influence strong and the weak compared to the 6:4>base pursues compared to the 8:2>base pursues compares 10:0.In the jointing ahead of time,between three levels does not have the remarkable difference.But starts from the florescence,between three levels has the remarkable difference,moreover in grouting period has the extremely remarkable difference.Increases along with applies fertilizer after topdressing time moves to the photosynthesis speed to increase gradually. 2 The influence about different cultivation measure to raises the wheat 12 soil ecologyFrom the tillering stage to the grouting time stage,shallow rotary cultivation drilling wheat field ground temperature being suitable,is advantageous to the wheat vigorous and healthy growth.From divides the tiller and joints to the jointing stage to the grouting stage needs the nitrogen to be many,needs the nitrogen quantity the grouting time to the mature period wheat to be few.Under identical processing,in wheat's different birth time,the wheat to the nitrogen absorption is different,each processing to the grouting stage achieves the peak in wheat's earing period to the nitrogen absorption.The row spacing is 20cm,the basic seedling is 2,250,000/hm~2,executes when the nitrogen total quantity is 300kg/hm~2,the wheat in the different time to the fast-acting nitrogen phosphorus's use factor is high.3 The influences about different cultivation measure to raises the wheat 12 output and the constitution factorThe test result indicated that under the different planting density applies fertilizer extremely obviously affects the output of wheat,along with quantity fertilizer increase, each planting density's output of wheat presents the varying degree reduction;Under the applying fertilizer level the different planting density's output of wheat displays certain density effect respectively,the basic seedling 2,250,000/hm~2 the outputs of wheat are extremely remarkable are higher than basic seedling 3,000,000/hm~2,3,750,000/hm~2;The weight of a thousand seeds achieves the quantity fertilizer and the population density factor influence the extremely remarkable level,the quantity fertilizer increases causes three planting densities the weight of a thousand seeds to appear the varying degree elevation, particularly the basic seedling 3,000,000/hm~2 community changes are obvious,and the performance is 3,000,000/hm~2 time applying fertilizer levels enhances the weight of a thousand seeds function to be stronger;The weight of a thousand seeds follows the crowd the volume density to increase reduces gradually,increases in the process by the basic seedling 2,250,000/hm~2 to 3,000,000/hm~2 and,3750,000/hm~2 to display especially obviously,executes a nitrogen total quantity 300kg/hm2 horizontal lower density to increase to the weight of a thousand seeds adverse effect obtains the certain extent alleviation;In summary,the density and applies fertilizer to the grain grouting has quantity and the quality dual influences,under the same quantity fertilizer condition,the population density is bigger,the weight of a thousand seeds is lower.Grain full fullness is lower,its bulk specific gravity is smaller.The test result also indicated that after the nitrogenous fertilizer,moved to the production increase the primary cause to increase the Guangzhou number of seeds and the weight of a thousand seeds.4 The influence about different cultivation measure to raises the wheat 12 quality charactersExecutes the nitrogen total quantity is extremely remarkable to the peak viscosity and the valley value viscosity influence,but other factors are not remarkable to the peak viscosity and the valley value viscosity's influence.Executes nitrogen total quantity 150kg/hm~2 and the 225kg/hm~2 is remarkable to the peak viscosity valley value viscosity influence phase difference,executes nitrogen total quantity 225kg/hm~2 and 300kg/hm~2 is not remarkable to the peak viscosity and the valley value viscosity influence difference. This experiment indicated that regarding raises the wheat 12 execute the nitrogen total quantity when the 225kg/hm~2,may increase the noodles the elasticity.Five factors to raise the wheat 12RVA dextrinize time and the dextrinize temperature effect are not remarkable, but under the same thickness of sowing,increases the dextrinize the time to increase first drops after applies fertilizer,but after the dextrinize temperature actually first drops, elevates.Executes the nitrogen total quantity to raise the wheat 12 starch subsidence value,the bread flour inflation potential and the bread flour alkaline water confining force influence is remarkable.Increases the bread flour along with the quantity fertilizer the subsidence value,the inflation potential and the alkaline water confining force increases,under each planting density time the applying fertilizer level 225kg/hm~2 subsidence value is most ideal,high applying fertilizer level(300kg/hm2) when does not favor forms the good bread flour subsidence value,the inflation potential and the alkaline water confining force.
