Abstract:

The study aims to get the information of drought resistance and frost resistance of potato in different planting ways, and provide meteorological services for farmers and production managers. 'Qingpotato No.9' was selected as the material, 8 planting patterns were set up to compare the frost and drought resistance effects by using variance and agrometeorological disaster risk index analysis. The results showed that the side planting of the full film double ridge and big ridge mask had a good effect because of the low risk index of good heat and moisture preservation performance. The risk index of ridge mulching, flat mulching and ridge furrow planting was smaller and with less effect. The rest four planting modes (no mulching film, double row, full sky star and parallel planting) had high risk index and poor effect of drought and frost resistance. Therefore, in Ningxia potato planting area with frequent drought and frost, the method of whole film double ridge big ridge mask side planting is recommended to farmers, which could achieve the effect of increasing production and improving quality.

Key words: ‘Qingpotato No.9’, different mulching, anti-frost, drought resistance
