土壤紧实度对花生荚果生长发育的影响
Effects of soil tightness on growing dynamic of peanut pods
摘要
Abstract
In order to identify the proper soil tightness for peanut pod growth and development,different soil bulk density treatments were designed by using soil column cultivation method,the effects of different soil tightness on pod growth of peanut were studied.The results showed that too high bulk density of soil was not conducive to the formation and drilling in the soil of peanut needles,pod enlargement and dry matter accumulation during the whole peanut growth period.Although soil bulk density was beneficial to the formation and drilling in the soil of peanut needles,pod enlargement and dry matter accumulation in the early growth period,but it was not conducive to the formation and drilling in the soil of peanut needles and small pods growing to large ones in the middle and late stage.Both too high or too low soil bulk density could reduce the number of medium and large pods,and result more small pods,less dry matter accumulation in the late growth stage.The suitable soil bulk density (1.2-1.3g/cm3) was beneficial to the formation and drilling in the soil of peanut needles,pod enlargement and dry matter accumulation in the whole growth period of peanut.In the late mature period,it would form more medium and large pods with greater dry matter accumulation and fewer small pods.关键词
