要不断增加粮食产量,必须从措施上、理论上加以总结研究提高。现代农作物都是白垩纪喜光植物的后代,对光要求很高。水稻的生物产量有90～95％来自光合产物。水稻的经济产量(谷米)实质上是把太阳总辐射的光能(以下简称太阳能)转化为化学能,提供人类营养的需要。“如果没有太阳放射到我们这里的排斥运动,地球上的一切运动都一定会停止。”(自然辩证法63页)可见光是一个很重要的生态条件,研究提高水稻光能利用,从而提高水稻的产量,是值得重视的问题。因此首先要了解光的自然资源情况。现将广州地区太阳能的资料,加以整理,找出其变化的规律,
To continuously increase the output of grain, we must sum up and improve the measures in theory and theoretically. Modern crops are descendants of the Cretaceous hippocampus, demanding light. The biological yield of rice is 90-95% from photosynthate. Economic output of rice (grain rice) is essentially the total solar radiation solar energy (hereinafter referred to as solar energy) into chemical energy to provide human nutrition needs. “Without any campaign of exclusion from the sun to our place, all movement on Earth will cease.” (Dialectics of Nature 63) Visible light is a very important ecological condition that studies increasing light energy use in rice to increase rice production , Is a problem worth attention. Therefore, we must first understand the natural resources of light. Guangzhou region is now the solar energy data, to be sorted out to find out the law of change,
