不同土壤质地对小麦生长发育及其生理特性的影响
Effects of Different Soil Textures on Growth and Physiological Characteristics of Wheat
摘要
Abstract
To select suitable soil texture for wheat production, several morphological and physiological indexes of Bainong AK58 in three kinds of soil textures( loamy,sandy soil and clay) at different growing stages were studied,including population size,plant height,root length,number of root,number of tillers, chlorophyll content and water content of plant. The results showed that, at the seedling stage, the population size in loamy soil was the biggest,sandy soil came second,and clay soil was the smallest;plant height and root length in loamy soil were the highest, but which in sandy soil were the lowest;water content of plant was similar in loamy soil and clay soil,but sandy soil was lower slightly. In the overwinter period,for the population size of three kinds of soil textures,loamy soil was the biggest,and clay soil was the smallest;but plant height in clay soil was the highest,loamy soil and sandy soil were lower;both root number and water content in three soil textures were similar. In the rising stage, the population size of three kinds of soil texture reached the maximum value,without too large difference;for plant height and tiller number, clay soil was the highest, and sandy soil was slightly higher than loamy soil;but root number,chlorophyll content and water content had no significant difference among the three soil textures. In the filling stage,the population size in loamy soil was slightly lower than that in clay soil,and sandy soil was far lower than the others;plant height in loamy soil was similar to sandy soil,and clay soil was the lowest;but the root length and root number were the highest in clay soil,followed by sandy soil,loamy soil were the lowest;tiller number in clay soil was much higher than that in loamy soil and sandy soil;the content of chlorophyll and water content of plant in loamy soil were the highest, clay soil was slightly higher than the sandy soil. In the mature stage, the population size in loamy soil and clay soil were similar,and the lowest was in sandy soil. For yield of wheat,theoretical yield in three soil textures was as clay soil>loamy soil > sandy soil,which in loamy soil and sandy soil were respectively 87. 85% and 62. 30%of that in clay soil. Specifically, grain number per ear and 1 000-grains weight of clay soil were the highest,but the ear numbers of loamy soil reached the top,and the difference of yield components among three soil textures were all significant.关键词
