摘　　要：以"辽核"为试材,使用不同浓度的乙烯利、萘乙酸混合液进行输液滴干,旨在找到使用调节剂促进核桃青皮开裂的最合适时期和浓度,以节省采收劳力,集中收果,同时不对树体造成损坏而影响第2年的果实产量。结果表明:收果前18d输液滴干10L的300mg/L乙烯利+600mg/L萘乙酸混合溶液,可使青皮开裂率达83%;在收果前6d输液滴干10L的500mg/L乙烯利+1 000mg/L萘乙酸混合溶液,可使青皮开裂率达78%,而且没有加重落叶,多项品质得到了一定提高。试验表明,调节剂输液滴干促进核桃采收可以在生产上推广应用。Taking‘Liao He＇walnuts cultivar as the test material,the experiment were conducted to get the best time of using regulator and its best concentration,to promote the green husk cracking rate,and save the harvest labor and reap intensively.Trunk transfusion and drip with Ethrel and Naphthalene acetic acid mixture of different concentrations were applied.The results showed that walnut green husk cracking rate was 83% when trunk transfusion and drip with 10 L mixed 300mg/L Ethrel and 600mg/L Naphthalene acetic acid was made 18 days before picking the fruit.And the rate was 78% when trunk transfusion and drip with 10 Lmixed 500mg/L Ethrel and 1 000mg/L Naphthalene acetic acid was made 6days before harvest.Fruit quality had improved while no more leaves had fallen.The test indicated that trunk transfusion and drip with regulator could promote walnut harvest,so it could be generalized in production.
