摘要
泡核桃早实栽培一直是制约其早期栽培效益发挥和产业发展的技术难题。通过多年试验,摸索出生长旺季喷施富氧钾肥、螺旋状环剥造伤及花期人工辅助授粉等早实丰产栽培技术及林畜复合经营技术。实现了6 a树龄泡核桃植株结果率达100%、均株干果产量为1.6 kg,分别比对照高73个百分点和7倍的经营效果;试验林分株均枝条数215.2条、结果枝平均长度11.6 cm、主枝延长枝平均长度21.9 cm,分别为对照95.4 cm、16.8 cm、112 cm的2.3倍、69%和19.6%,采用早实栽培技术有效实现了以果压梢的目的。
Sigillate walnut early fruiting cultivation has been a technical challenge restricting the develop- ment of early cultivation effects. Through years of trial, early fruiting and high yield cultivation and man- agement technique of mixed forest livestock such as spraying oxygen-rich potash in the growth season and artificial pollination were explored . Results showed that the fruit rate of six year Sigillate walnut plants was up to 100% , on average each strains produced 1.6 kg of dried fruit 73% and 7 times higher than control respectively; the branch number of each plant was 215.2, average length of fruiting branch was 11.6 cm, the average length of main branch was extend to 21.9 cm, which was 2.3 time, 69% and 19.6% compared with control 95.4 cm, 16.8 era, 112 cm respectively. The early fruiting cultivation techniques could effectively to achieve the purpose of more fruiting.
