为了探讨各种生长调节剂对李树发枝力、新梢平均长度、树干粗度和果实产量的影响。我们于1976～1980年在明斯克地区陆新农场的李园进行了施用生长调节剂的试验。供试果园于1976年定植,株行距为5×1.25米。供试品种为,系意大利李,砧木为樱桃李。供试生长调节剂为二甲基琥珀酰肼,KAHY(抑制剂),矮壮素和乙烯利。李树开花后10～15天进行首次喷施。共喷施三次,每次间隔一个月。每一处理选取4株幼树以测定植株的生
In order to investigate the effects of various growth regulators on the shoot pruning, the average length of shoots, the thickness of trunk and the fruit yield. We conducted a trial of growth regulators in Lee Gardens, Lu Xin Farm, Minsk, from 1976 to 1980. Test orchard in 1976 colonization, spacing of 5 × 1.25 meters. Test varieties for the Department of Italian Lee, rootstock cherry plum. Test regulators for the development of dimethyl succinyl hydrazide, KAHY (inhibitor), chlormequat and ethephon. Lee flowering after 10 to 15 days for the first time spraying. A total of three spray, each interval of one month. Four young saplings were picked for each treatment to determine the plant’s viability
