Study on Nutrient Uptake Characteristics of Rice Variety Tianfengyou 101
摘要
Abstract
The nutrient uptake characteristics of rice new variety Tianfengyou 101 were studied through fertilization tests in high-yielding, middle-yielding and low-yielding paddy fields .The results showed that Tianfengyou 101 was the most sensitive to ni-trogen, and more sensitive to phosphorus .The seed of Tianfengyou 101 contained higher nitrogen and phosphorus than the stalk of this variety , while the latter contained higher potassium and zinc than the former .Under the condition of balanced nutrient supply , the contents of various nutrients in both seeds and stalks were higher .The amount proportion of N , P2 O5 and K2 O absorbed by Tian-fengyou 101 was 1.00∶0.36∶1.63 in low-yielding field, 1.00∶0.42∶1.81 in middle-yielding field, and 1.00∶0.44∶1.81 in high-yielding field.In this variety, the transportation rate of nitrogen , phosphorus, potassium and zinc was 61.5%, 62.0%, 15.6%, and 36.6%, respectively.关键词
