本文叙述了对梨树应用矮壮素和常用无机肥料与有机——无机肥料的研究结果。目的是想根本改善像威廉士梨、红威廉士梨和其它一些优良品种梨幼树的营养状况,因为在气候湿润和瘠薄的山地土壤条件下,会促使枝条旺盛生长(达到1.5——2米),给修剪带来很大困难,蓝加大了修剪量。而使用矮壮素能够抑制梨树新梢的生长,控制枝条长度和促进结实器官的形成。由于肥料和矮壮素对梨树的影响是相反的,因此研究它们之间的相互关系是有意义的。
This article describes the results of research on application of CCC and common inorganic fertilizers and organic-inorganic fertilizers to pear trees. The aim is to fundamentally improve the nutritional status of young saplings such as Williams, Red Williams and other fine varieties of pear trees because of their vigorous growth in wet and barren mountainous soils (up to 1.5-2 meters ), To the pruning great difficulties, blue increased the amount of pruning. The use of CCC can inhibit the growth of new shoots, control the length of shoots and promote the formation of solid organs. Since the effects of fertilizers and chlormequat on pear trees are the opposite, it makes sense to study the interrelationships between them.
