为丰富本地优质、抗病核桃种质资源,引进“清香”核桃苗木在费县青石山区瘠薄地进行丰产栽培试验,结果表明:按株行距3m×5m栽植在0.5~0.6m厚的土壤中,有利于丰产;对6年生树幼果初期喷1次、果实膨大期连喷2次禾神元多效微生物菌肥0.33%浓度药液(间隔期7d)+9月下旬株施土杂肥50kg、复合肥2kg,较对照提高了结果率81.9%、结果数27.5%、单果质量8.1%、株产37.8%、667m~2产量37.8%,是促进结果、提高产量、延迟落叶的最佳选择,适合在临沂乃至山东大力推广。
In order to enrich the local germplasm resources of high quality and disease-resistant walnut, walnut seedlings were introduced into “Qingxin” walnut seedlings in barren land in Feixian County. The results showed that the soil was planted in 0.5 ~ 0.6m thick , Is conducive to high yield; 6-year-old tree early spray 1, the fruit swollen even spray 2 times Hemu yuan multi-effect microbial fertilizer 0.33% concentration of liquid (interval 7d) + late September plant soil hybrid Fertilizer 50kg, compound fertilizer 2kg, compared with the control results increased 81.9%, the number of results of 27.5%, 8.1% of fruit quality, yield of 37.8%, yield of 667m ~ 2 37.8%, is to promote the results, increase yield, delay the best deciduous Choice, suitable for promotion in Linyi and Shandong.
