本试验的目的是进一步测定不同浓度的西维因、萘乙酸在盛花后两周喷射金冠、国光苹果的疏除效应,并探索西维因和萘乙酸混用的效果。结果表明:西维因2000ppm、萘乙酸10、20、40ppm 及西维因1000ppm+萘乙酸10ppm 混用各处理对金冠均起到显著的疏除作用,疏除量达到或超过人工疏果的水平。除西维因2000ppm的处理树势太弱,疏除效应虽然显著但没有提高产量外,其他各药剂处理的两年平均株产都高于不疏果的对照树,明显地缩小了大小年幅度,并提高了果实品质。西维因疏除作用发生的时间比萘乙酸早。萘乙酸40ppm 对果实增大有一定的抑制作用。未见其他任何药害。萘乙酸40、60ppm 及萘乙酸20ppm+西维因2000ppm 各处理对国光都没有发生显著的疏除效应。
The purpose of this experiment is to further determine the effects of different concentrations of cinebine and naphthalene acetic acid on the sparse golden apple and Guoguang apple in the two weeks after full blossom and to explore the effect of mixed use of xylene and naphthalene acetic acid. The results showed that all the treatments of 2000mg of SAWEI, 10,20,40ppm of naphthalene acetic acid and 10ppm of XVI were mixed with 10ppm of naphthalene acetic acid to eliminate all the gold crowns. In addition to the treatment of 2000ppm of XVI due to too weak shrubs, sparse effect although significant but did not increase yield, the other two agents to deal with the average annual plant yield is higher than the control tree without thinning, significantly reduced the size of the annual rate , And improve the quality of the fruit. West Vigorously due to sparse effect occurred earlier than naphthalene acetic acid. Naphthalene acetic acid 40ppm increase the inhibition of certain fruits. No other drug damage seen. Naphthalene acetic acid 40,60 ppm and naphthalene acetic acid 20ppm + West-dimensional 2000ppm of the treatment of Guoguang no significant sparse effect.
