摘要:

在旱作栽培条件下,本研究以马铃薯品种‘维拉斯’为材料,聚焦花期不同株高时期,开展了叶面喷施植物生长调节剂多唑·甲哌鎓、烯效唑的试验。旨在综合比较这2种植物生长调节剂在不同株高时期叶面喷施,对马铃薯生长特性、农艺性状以及产量的影响。试验结果显示,产量与株高呈现极显著负相关,相关指数为-0.8935。在不同株高时喷施植物生长调节剂,均达到了极显著增产的效果。其中,在株高60 cm左右时,叶面喷施多唑·甲哌鎓效果最为理想,‘维拉斯’产量达到最高,相较于对照增产22.79%。叶面喷施植物生长调节剂能够促使株高矮化、块茎产量增加。在大田生产中,明确在植株达到多少厘米时进行药剂处理,对于生产者具有现实指导意义。本研究结果以期为马铃薯品种‘维拉斯’种植时的化学调控提供基础数据。

Abstract:

Under the condition of dry cultivation, the potato variety ‘Villas’ was used as the material, and the plant growth regulators were sprayed on the leaves at different plant height periods during the flowering stage. The effects of polyazole mepiquat chloride and uniconazol on the growth characteristics, agronomic traits and yield of potato at different plant height periods were compared. The results showed that there was a significant negative correlation between yield and plant height, and the correlation index was -0.8935. Spraying plant growth regulators at different plant heights had a very significant effect on increasing yield. When the plant height was about 60 cm, the effect of foliar spraying of polyazole mepiquat chloride was the best, and the yield of ‘Villas’ was the highest, which was 22.79% higher than that of the control. Spraying plant growth regulators on leaves promotes plant height dwarfing and tuber yield increasing. In field production, it is of practical guiding significance for producers to clarify how many centimeters of plant height are treated with chemicals, in order to provide basic data for chemical regulation of potato variety ‘Villas’ planting.
