| Experiment starts from ecological factor for soybean quality influence, the characteristic that soybean quality ecological characteristic and quality heredity express be elaborated. And from the law of quality ecological factor change, have revealed the mechanism of quality ecological adjusting control.The soybean sample of different area using the 1207 sources of 3 years in Heilongjiang be analysed. The high negative correlation is between the fatty and protein content in soybean production. This kind of relation be influence by the different year of climate, explain it is very significant that the negative relation of its soybean protein and fatty content when in the year that favourable fatty content forms and unfavourable protein content forms. The stability that negative correlation between protein and fatty content is obvious,when the coefficient of regression more close to - 1. However, the stability that negative correlation between protein and fatty content is more difference, when the coefficient of regression depart from - 1.The soybean protein variation range is 37.47-44.21% and fatty variation range is 18.35-22.59% On Heilongjiang province production. 4.24 average discrepancy percent which the soybean variety in different location and years. The variety that is large change of the protein and fatty content is to suit to plant in fatty content expression higher suitable ecological district.The variety that is less variation of the protein and fatty content mostly is plant relative do not suit fatty content to form and the early-maturing area. Divide into different groups that quality expresses,using genetype groupping technology. Dongnong 46, Hongfeng 9, Kenfeng 9 and Suinong 10, 4 varietys are better hereditary stability for fatty content.It is not obvious for the reaction of sunshine with soybean's protein and fatty content. But between varieties have discrepancy, because different hereditary background. It is obvious between some variety's protein content and each month sunshine in soybean growth.From overall analysis, it is low linear correlation between the fatty content and each month sunshine in soybean growth. But between varieties, some variety's fatty content witheach month sunshine in soybean growth is related. That mostly linear correlation highly between the protein content and each month sunshine is early stage of soybean growth. However, the correlation between fatty content and sunshine mostly occered in later stage of soybean growth.The protein content of soybean with each month temperature of soybean growth is low negative correlation. Except August, it is positive correlation on significant at 5% between the fatty content of soybean and temperature on other month. By stepwise regression analysis, the equation can expressed that the relation between the fatty content of soybean and each monthly mean temperature in soybean growth: y=11.56+0.314X June+0.215Xseptember, R2=0.115. From equation, it is important function on the average temperature of June and September for soybean fat formed.Besides Except August and September, it is correlation on significant at 5% between the protein content of soybean and precipitation on other month. By stepwise regression analysis, the equation can expressed that the relation between the protein content of soybean and each monthly mean precipitation in soybean growth: y=39.792+0.011X June+0.023 XMay-0.008XJuly- 0.011X September, R2= 0.163, from equation, the precipitation of May, June, July and September is more important funcation for soybean protein content formed. Also,Besides August, the negative correlation on significant at 5% between fatty content of soybean and the precipitation of other month .By stepwise regression analysis, the equation can expressed that the relation between the fatty content of soybean and each monthly mean precipitation in soybean growth: y = 21.826-0.007X July +0.008XJune, R2 = 0.176.From equation, the precipitation of June and July is more important funcation for soybean fatty content formed.The change of entire protein content is keeped calm for variety of high fatty content, still maintain former order of protein content finally. It is same between ordinary and high fatty content varety beginning.but, almost same protein content on 3 layer is finally formed for ordinary variety.For high fatty content variety, when 60 days after flower, fatty content has reached peak, afterwards, submit the dropping tendency. For ordinary variety, keeps lower fatty content from beginning, drops afterwards somewhat to keep steady. The seeds of top layer always maintain a tendency of rising.3 high-oil soybean varieties (Suinong 14, Hongfeng 9 , Dongnong 47) were tested, discuss on the change law of protein and fat accumulate for high-oil soybean varieties between 2002 and 2003. Show as a result: High-oil soybean varieties does not relative change order of fatty content in the different years. The protein forms to submit the rising tendency in unfavourable fatty year, and the protein content accumulation has presented the parabola distribution of concave type in favourable fatty year, but the protein content will be smaller than after maturation. The accumulation of fat, it is greater that each kind change since its heredity is characteristic, but what is that form a tendency of balance andthe drops in unfavourable fatty year, however, the high-oil soybean varieties has presented the fatty accumulation course of identical tendency, from beginning is low , go up step by step, after reaching a highest value, begin a balanced tendency in favourable fatty year.With the soybean quality content, according to the relationship between soybean quality and geographical distribution, environmental condition, soil type, climate condition, and soybean trade and utilization, the soybean production region is divided into three districts: East-West high-oil district(â… ), and it can be divided into two subdistricts, West high-oil district(â… -A) , East high-oil district(â… -B); Middle and Southeast high-protein district(â…¡), and it can be divided into two subdistricts, Middle high-protein district( â…¡ -A), Southeast high-protein district( â…¡-B); North and East river-edge protein-oil balance district(â…¢), and it can be divided into two subdistricts, North protein-oil balance district(â…¢-A), East river-edge protein-oil balance district(â…¢-B).This research is tested for soybean in more location and years, discuss the single factor effect and synthesize effect between the major quality character which factor of protein and fat with light, temperature, water etc. under different ecological condition. Project again study soybean protein and fatty accumulation development law through experiment, reveal soybean quality to form , accumulate law , make the high quality principle and key technology of adjusting control , suggest that Heilongjiang soybean quality ecological partition, and suggest that soybean excellent quality cultivated technology can not directly act on soybean quality and output raising, and is to be improper for soybean quality or output to form the improvement of that part of ecological factor through change in ecological factor, reach high quality high yield finally. |
