本文以我国橡胶树北移中在不同温度、热量梯度地区大面积生产栽培的不同产量表现以及对温度,热量与橡胶的产量关系分析,证明橡胶树可以在温度、热量指标显著低于原产地和典型热带条件下达到丰产栽培的事实,并说明其农业气象学原理,在此基础上提出橡胶树丰产栽培的下限温度指标和达到我国植胶宜林地标准的北界温度指标。橡胶树丰产栽培的温度指标是:最低月均温多冬各平均值>15℃,极端低温冬平均值>5℃。此二项指标与我国热带区划指标一致,但热带区划中的积温指标是不必要的。符合我国植胶宜林地标准,目前有经济效率的生产性植胶温度北界指标是:最低月均温多冬平均值>14℃,极端低温多冬平均值>3℃。在此温度界限上胶园产量可达到并局部超过我国植胶宜林地产量要求。最低月均温<14℃,极端低温多冬平均值<3℃,是目前品系抗性水平条件下寒害严重、无稳定产量水平、不符合我国植胶宜林地标准的气候标志。以最低月均温多冬平均值≥13℃,极端最低温多冬平均值≥2℃为指标划出的广西植胶“第二北界”指标偏低,不符合实际。 In this paper, North China Rubber Tree moved north in different temperature and heat gradient area of ​​?? large-scale production and cultivation of different yield performance and temperature, heat and rubber yield analysis shows that the rubber tree can be significantly lower in temperature and calorie indicators than the origin and typical tropical Under the conditions to achieve high-yielding cultivation facts, and explain its principles of agricultural meteorology, on the basis of rubber tree high yield cultivation of the lower limit temperature index and reach our standard of planting plastic forest north boundary temperature indicators. Rubber trees yield cultivation temperature indicators are: the lowest average monthly average temperature of more than 15 ℃, extreme low temperature average> 5 ℃. The two indicators are consistent with the index of tropical zoning in China, but the index of accumulated temperature in tropical zoning is unnecessary. In line with our country plastic yinglin standards, the current economic efficiency of the production of plasticity temperature north boundary indicators are: minimum monthly average temperature of more than 14 ℃, extreme low temperature and more winter average> 3 ℃. At this temperature limit, the output of plastic garden can reach and partially surpass the requirement of plastic planting in our country. The minimum monthly average temperature <14 ℃, extreme low temperature and winter average <3 ℃, is the current level of resistance to severe chilling injury, no stable level of production, does not meet the standard of China’s plastic yinglin climate standard. The index of “the second northern boundary” of Guangxi’s plastic planting marked by the minimum mean monthly mean temperature of more than or equal to 13 ℃ and the average of the lowest and lowest mean monthly mean temperature of more than or equal to 2 ℃ is low, which is not in conformity with the actual conditions.
