“秦油2号”油菜植株内含物与菌核病扩展的关系

STUDY ON THE RELATIONSHIP OF PLANT CONTENTS IN RAPE CULTIVAR"QINYOU NO.2"WITH SCLEROTIOSE EXPANSION

通过对N、P、K不同水平的施肥条件下的“秦油2号”油菜植株内含物等与菌核病扩展间关系的研究，建立了27个数字模型，表明总氮、水溶性糖、含磷量、蛋氨酸、精氨酸、含水量与病斑扩展有密切关系，其次是甘氨酸、苏氨酸、谷氨酸、苹果酸和酰胺氮等．

Based on the relationship of plant contents in rape cultivar'Qinyou No.2'with sclerotiose expansion set up 27 mathematics models at different level fertilities（N,P,K）in the field and showed that the total nitrogen content,water soluble carbohydrates,phosphorous content,methionine,arginine and water content were related closely to spot expansion,but the glycine,threonine,glutamate,malic acid and amidonitrogen ere secondary.
