1、作者于六十年代初、中期,在本院农场进行稻田轮作试验已注意到光能与作物产量的关系。再综观国内外和区内农业生产单位,也发现不同复种方式、不同作物品种和不同水肥管理,其光能利用、光能生产和作物产量是不同的。 2、从作者在六十、七十及八十年代分别进行了一些光能测定分析及参阅国内外资料看,目前光能尚未充分利用,作物高产潜力尚巨大。 3、无论什么地区,应因地制宜,在考虑其他措施的同时应注意光能的充分利用,方能取得满意的效果。
1, Author In the early 1960s, in the mid-term, experimenting with crop rotation in the farms of our hospital has taken note of the relationship between light energy and crop yield. A comprehensive review of agricultural production units at home and abroad and within the region also shows that different ways of cropping, crop varieties and management of different water and fertilizers have different light energy use, light energy production and crop yields. 2. From the author’s analysis of light energy measurement and reference to domestic and foreign data in the 60th, 70th and 80th respectively, the light energy has not yet been fully utilized and the crop yield potential is still huge. 3, no matter what area should be adapted to local conditions, taking into account other measures should also pay attention to the full utilization of light energy, can achieve satisfactory results.
