为提高红星苹果的产量,我们于1990年,在锦县石山镇李家铺村孟宪凯果园,进行人工辅助授粉试验。该园有6年生红星苹果树195株,果园面积8.9亩,株行距5×6米。5月7—9日,对155株苹果树进行一次人工接粉,对30株进行两次人工授粉,用10株自然授粉树作对照。调查结果表明:一次授粉树比对照树花序坐果率提高51.31％,花杂坐果率提高50.29％,亩增产45.85％。二次授粉树比对照树花序、花朵坐果率,分别提高92.75％和77.46％。
In order to improve the production of Red Star Apple, we conducted artificial assisted pollination test in Mengxiankai Orchard, Lijiapu Village, Shishan Town, Jinxian County in 1990. The park has 6-year-old Red Star apple tree 195, 8.9 acres of orchards, spacing of 5 × 6 meters. From May 7 to May 9, 155 apple trees were planted manually, 30 pollination plants were pollinated twice and 10 natural pollination trees were used as controls. The results showed that the rate of fruit setting of one pollination tree was 51.31% higher than that of the control tree, the rate of fruit setting was increased by 50.29% and the yield of mu was 45.85%. Secondary pollination tree than the control tree inflorescence, flower setting rate, respectively, increased 92.75% and 77.46%.
