断根对农作物生长发育影响的研究现状综述

Research Status of Root Pruning on Growth and Development in Crop

根系生长发育状况与作物产量密切相关，合理调控根系生长可以促进作物地上部与地下部的协调发展，有利于产量提高。作物生产中存在多个伤害根系的耕作环节，明确不同断根程度对作物生长发育的影响，正确进行农田作业对作物生产具有重要意义。该文就断根对农作物生长发育的影响研究进行了综述。

Growth and development status of root was closely related with the yeild in crop, reasonable regulation the growth of root can promote growth of overground part and improve effectively yield of crop. There were multiple tillage links that might injure the root, so it was important to explicit the effect of root pruning extent on growth for correct cropland. The paper reviewed the current situation of root pruning on growth and development.
