怎樣發(fā)揮碳氫光核肥的大效益?

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

　　1、決定作物產(chǎn)量因素有五：<1> 葉面積，<2> 光合強度，<3> 光合時間,<4 > 呼吸作用,<5>經(jīng)濟系數(shù)(經(jīng)濟產(chǎn)量÷生物產(chǎn)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產(chǎn)量途徑：(1)合理密植;<2> 間套復種;<3> 選用上部葉片直立、中下部葉片傾斜的株型緊湊抗倒伏矮桿品種;<4> 加強田間管理。

　　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、防止土壤板結，要保證作物根部通氣，雨后及時排澇，無氧呼吸不利于作物生長。

　　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.
