Abstract:
以海南省国营大丰农场选育的橡胶树新品种‘大丰95’中低割龄树为材料,采用相关、通径、多元回归分析等方法,研究橡胶产量(y)与其年均割次株产干胶量(x1)、年割胶刀数(x2)、每公顷有效割株数(x5)等5个相关性状的关系,以及产量构成因素的作用效应。研究表明:3个产量构成因素与产量有紧密的关系,偏回归系数达极显著水平,直接通径效应为较高正值,其中每公顷有效割株数最高,其次是年均割次株产干胶量,第三为年割胶刀数,且年割胶刀数与每公顷有效割株数和年均割次株产干胶量之间的差异达1%显著水平。说明橡胶树‘大丰95’中低割龄高产高效栽培技术途径是:在一定的年割胶刀数基础上,主要考虑每公顷有效割株数和年均割次株产干胶量因素。建立的回归方程(y=-1434.7455+16.1139x1+8.2047x2+2.5617x5)可定量描述该品种产量与其构成因素间的关系。
