试验研究了旱立停和农用保水剂2号两种抗旱剂在马铃薯上的应用效果。通过田间试验,分析抗旱剂拌种或沟施处理对马铃薯出苗、结薯和产量等指标的影响情况。试验结果表明,100kg种薯用旱立停15g拌种和120g/667m2沟施以及农用保水剂2号2kg/667m2沟施可以促进马铃薯早出苗1~3d、提高马铃薯出苗率2.0%~10.1%、增加产量22.4%~27.3%。抗旱剂可以用于马铃薯生产。
The effect of two kinds of drought-resisting agent of dry stand and agricultural water-retaining agent No. 2 on potato was experimentally studied. Field experiments were conducted to analyze the effects of drought-resistant agents on seedling emergence, tuber yield and other indicators of seed dressing or furrow treatment. The results showed that the seedlings of 100kg seedling could promote early emergence of potato by 1 ~ 3d and improve the emergence rate of potato by 2.0% ~ 10.1% with 15g seed dressing and 120g / 667m2 furrow irrigation and 2kg / 667m2 furrow dressing of No. Increase output 22.4% ~ 27.3%. Drought-resistant agents can be used for potato production.
