水稻是一种高产稳产的粮食作物。但是,目前在生产上,常因栽培管理不当而引起其生长发育失调,造成一定程度的减产。其主要原因之一,是我们对于水稻个体生长发育规律认识不足,不能很好地根据植株外部形态特征表现(主要是叶片),推知内部正在新建器官的分化发育状况,而予先地采取必要栽培措施,如营养物质的供给,促或控,使
Rice is a high and stable yield of food crops. However, at present, its production and development often cause its growth and development imbalance due to inappropriate cultivation and management, resulting in a certain degree of yield reduction. One of the main reasons is that we do not know enough about the rules of individual growth and development of rice and can not well perform the necessary cultivation according to the external morphological characteristics of the plants (mainly the leaves), inferring the differentiation and development status of the newly built organs in the interior, Measures, such as the supply of nutrients, promotion or control, make
