采用联合国粮农组织推荐的产量与水的关系中的《农业生态地带法》对广西龙眼经济产量潜力作初步探讨,此方法的思路是,计算标准作物总干物质,加以考虑作物种类、温度、发育时期、叶面积、净于物质、收获部分等的相关和影响,再结合广西的实际情况进行计算,共选用了7个参数。从计算得知,广西龙眼经济产量潜力为每亩3500kg左右.目前大面积平均产量为每亩450kg左右,其中包括大小年树,老 Based on the “Agro-ecological Zone Law” in the relationship between output and water recommended by the UN Food and Agriculture Organization (FAO), the economic output potential of Guangxi longan is discussed. The idea of ​​this method is to calculate the total dry matter of standard crops and take into account crop species, temperature, Period, leaf area, net material, harvest part of the correlation and influence, combined with the actual situation in Guangxi calculation, a total of seven parameters selected. From the calculation, the economic output potential of Guangxi longan is about 3500kg per acre. At present, the average output of a large area is about 450kg per mu, including the size of the year tree, the old
