怎样发挥碳氢光核肥的大效益?

　　How to give full play to the maximum benefit of hydrocarbon?

　　1、决定作物产量因素有五：<1> 叶面积，<2> 光合强度，<3> 光合时间,<4 > 呼吸作用,<5>经济系数(经济产量÷生物产量)

　　1, decided to have five crop yield factors: <1> <2> leaf area, photosynthetic intensity, photosynthetic time <3>, <4 > <5> (respiration, economic coefficient, economic yield, biological yield)

　　2、提高作物光能利用率及产量途径：(1)合理密植;<2> 间套复种;<3> 选用上部叶片直立、中下部叶片倾斜的株型紧凑抗倒伏矮杆品种;<4> 加强田间管理。

　　2, improve crop light utilization rate and yield way: (1) reasonable close planting; <2> intercropping multiple cropping; <3> selected upper leaves erect, middle and lower leaves tilted compact type, lodging resistant short rod varieties; <4> strengthen field management.

　　3、防止土壤板结，要保证作物根部通气，雨后及时排涝，无氧呼吸不利于作物生长。

　　3, to prevent soil compaction, it is necessary to ensure that the root of the crop ventilation, timely drainage after rain, anaerobic respiration is not conducive to crop growth.
