摘要
热带作物对磷肥的利用率极低,通过调控磷肥的根际效应来提高其吸收效率,是提高磷肥利用率的有效途径之一。本文提出了研究热带作物磷肥根际生物有效性的意义。
The availability of P fertilizer is low in tropical crops. One of the ways for improving the availability of P fertilizer is to regulate the rhizospheric effect to increase the absorptivity of the P fertilizer. The importance of the rhizospheric bioavailability was put forward. The main methods for improving the rhizospheric bioavailability of P fertilizer were summarized. The factors affecting the rhizospheric bioavailability of P fertilizer and the prospects of study on the rhizospheric bioavailability of P fertilizer were reviewed.
