| 摘 要： | 不同树龄柠檬在开花期与幼果期,通过抹除全部不带花蕾的嫩梢,研究其对柠檬产量的影响.结果表明,在第一次生理落果至第二次生理落果结束时,均未出现生长的新梢.柠檬的结果量、春花着果量及其坐果率均较对照增加,春花着果量比对照增加46.0％～92.4％.3年生、4年生、5年生柠檬树平均单株产量分别比对照高11.8、9.9、9.8 kg,平均产量分别为26 748、40 570.5、51 720 kg/hm2,分别比对照增产18 813、16 626、17 652 kg/hm2；经济效益分别比对照增加49 467、43 300.5、50 775元/hm2.梢抽生数量、平均梢长都与第二次生理落果后春花着果、柠檬着果率呈极显著负相关；柠檬落果数量与平均单株产量及实际测定产量呈极显著相关.

| Abstract: | A field experiment was carried out by erasing all the shoots of non-bud in the blossom and fruitlet period of lemon trees with different ages to study its yields.Results showed that after different treatments,the trees did not grow new shoots from the first physiological fruit-dropping to the end of second physiological fruit-dropping.Compared with the control,the amount of fruits, the flower setting amount and its fruit set rate(46.0 %-92.4 %) was increased.The average yield per plant planted 3-yr,4-yr,5-y... |
