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=-1 434.745 5+16.113 9X1+8.204 7X2+2.561 7X5)可定量描述该品种产量与其构成因素间的关系。
Abstract
A new variety ‘Dafeng 95’ of Hevea brasiliensis at young and middle tapping ages selectively bred by National Dafeng Farm of Hainan Province was used as plant materials. The interrelationship among yield and its five related traits including mean annual dry rubber yield per tree per tapping, the number of tapping per year and the number of tappable trees per hectare etc. was investigated by using correlation, path coefficient and multiple regression analysis, and the relative effects of the yield components on yield in the variety of H. brasiliensis were also studied. The results showed that three yield components were closely related with yield, their partial regression coefficients were up to very significant level, and all of their direct path effects were higher positive value. Among the five factors, direct path effect value of the number of tappable trees per hectare was the highest, followed by mean annual dry rubber yield per tree per tapping and the number of tapping per year. And the difference among the three traits reached up to 1% extremely significant level. The technical solution of high-yielding and high-efficiency cultivation for young and middle tapping aged ‘Dafeng 95’ was suggested as follows: besides the necessary number of tapping per year, the number of tappable trees per hectare and mean annual dry rubber yield per tree per tapping should be highly considered. The regression equation “Y=-1 434.745 5+16.113 9X1+8.204 7X2+2.561 7X5” for quantitatively describing the relationship between yield and its components was feasible.
