摘要
研究调查了临高、定安、东方和琼中4个市县包含6个林龄的橡胶林,为橡胶储备林质量精准提升技术研究提供数据支撑。结果表明:定安县的橡胶林生长情况最好,胸径和树高年均增长量分别为为2.42cm、1.46m;东方市的橡胶林生长情况较差,胸径和树高年均增长量分别为为1.62cm、0.73m。降雨量是影响橡胶生长的主要因素;对于东方市等橡胶栽培低适宜地区,应着重培育需水量较少的橡胶新品种,以适应该地区气候。
In order to provide data support for the research of precise quality improvement technology of Hevea brasiliensis,six rubber forests of different ages were investigated in four cities and counties in Lingao,Ding’an,Dongfang,and Qiongzhong.The results shows that the growth of Hevea brasiliensis forests in Ding’an City is the best,with an average annual increase of diameter at breast height and tree height of 2.42 cm and 1.46 m respectively;The growth of Hevea brasiliensis forests in Dongfang City is relatively poor,with the average annual growth of diameter at breast height and tree height being 1.62 cm and 0.73 m respectively.Rainfall is the main factor affecting Hevea brasiliensis growth;For areas with low suitable Hevea brasiliensis cultivation such as Dongfang City,emphasis should be placed on cultivating new Hevea brasiliensis varieties that require less water to adapt to the climate of low suitable areas.
