移栽油菜在当前油菜种植产业中占有重要的地位,其具体作用如下:第一,移栽后油菜的根系受损,导致它生长变缓,更多的营养物质得以被积累。第二,移栽意味着油菜可以得到合理的密植,有利于提高整体的产量。另一方面,虽然移栽油菜利处多,但并非经过移栽的油菜都能够高产。因此,掌握必要的油菜移栽后的大田管理技术是十分有必要的。对于油菜来说,怎样通过人工来调整主干与侧叶的多少关系,使更多的叶片的绿色部分受光,提高其净光合速率,是提高油菜的质量、实现大田高产、获得更多经济效益的关键。
Transplanting canola occupies an important position in the current rapeseed planting industry. The specific functions are as follows: First, the rape root system is damaged after transplanting, causing its growth to slow down and more nutrients to be accumulated. Second, transplanting means that rape can be rationally densified, helping to increase the overall yield. On the other hand, although transplanting rape more benefits, but not transplanted rape can be high yield. Therefore, it is necessary to master the field management techniques after transplanting the necessary rapeseed. For rape, how to manually adjust the relationship between the trunk and the lateral leaves, so that more leaves of the green part of the light to improve its net photosynthetic rate is to improve the quality of rapeseed, to achieve high yield field, more economic benefits The essential.
