Study on interaction between water and fertilizer under jujube-cotton intercropping
摘要
Abstract
To explore the interaction between water and fertilizer in different growth stages of crops for jujube -cotton intercropping ,we explored the spatial distribution soil moisture and nutrients in different depth .The result showed that jujube and cotton at different growth stages had different requirementsfor water .From July to August ,water requirement increased with the growth process .Jujube needed more water than cotton .And the competition for water between the two crops became more severe at shoot growth ,flowering ,and the young fruit periods ,being more obviously for 20 ~ 40 cm of soil depth .From late August to early September ,jujube required less water than cotton did and the competition for water and available phosphorus weakened .There was competition for utilization of soil available K between dates and cotton during the whole growing period .The competition was more intense during he young fruit and cotton peach boll stages .关键词
