三十烷醇是近年来研制成的一种新型植物生长调节剂。据报导,三十烷醇对柑桔的保果有显著的作用。为了进一步验证三十烷醇在本地柑桔上的使用效果,为生产上推广应用提供科学依据,笔者于1983年5—9月进行了这方面的试验,现将试验所得初步结果报告如下。一、材料和方法试验在紫溪公社创业队进行,供试品种为12年生温州蜜柑,栽植密度4×4米,树形为自然园头形,树与树之间无交接遮荫现象。供试果园土壤、砧木、树势及管理条件基本一致。供试三十烷醇系江西工学院所产。试验设1PPM和0.5PPM两种浓度处理。以喷清水为对照,并以0.2％
Triacontanol is a new plant growth regulator developed in recent years. Triacontanol is reported to have a significant effect on the preservation of citrus fruits. In order to further verify the use of triacontanol on local citrus fruits and provide a scientific basis for the promotion of production, the author carried out experiments in this field from May to September, 1983, and the preliminary results of the tests are reported as follows. Materials and methods The experiment was carried out in the venture team of Purple Creek commune. The tested varieties were 12-year-old Satsuma mandarin. The planting density was 4 × 4 meters. The tree shape was natural head shape, and there was no shade between the trees. For test orchard soil, rootstock, tree potential and management conditions are basically the same. Triacontanol for Jiangxi Institute of Technology produced. Experimental set 1PPM and 0.5PPM two concentrations of treatment. To spray water as a control, and 0.2%
