在高州市三个试点开展橄榄G18品系适应性试验,结果如下:利用8~9年生橄榄树改接后第4年及1年生砧木嫁接后第9年,其平均单株产果量达22.9 kg,单株平均增产15.1 kg,产量增益216.82%;平均单位树冠投影面积产果量达0.77 kg/m2,平均增产200.01%;试点间单株产果量和单位树冠投影面积产果量的变异系数(CV)分别接近或小于试点内的CV;改接株平均冠幅生长量与对照接近,但1年生砧木嫁接株的比对照大18.75%。G18嫁接亲和性较好,生长较快,丰产性好,立地适应性强,是一个值得在生产上大力推广的优良品系。
The adaptability test of Olive G18 was carried out in three pilot projects in Gaozhou. The results are as follows: The average fruit yield per plant reached 22.9 kg in the 9th year after grafting with 8-9-year-old olive trees and the 4-year-old and 1- , The average yield per plant was 15.1 kg, and the yield gain was 216.82%. The average yield per unit area of canopy reached 0.77 kg / m2 with an average yield of 200.01%. The coefficient of variation of fruit yield per plant and canopy projected area per plant (CV) were close to or less than the CV in the pilot. The average crown growth of the reformed plants was close to that of the control, but the grafted plants of one-year-old rootstock were 18.75% larger than the control. G18 good grafting affinity, rapid growth, high yield and good site adaptability, is a worthy promotion in the production of excellent lines.
