不同密度对马铃薯产量及经济效益的影响

Effects of Different Density on Yield and Economic Benefits on Potato

为探索适宜三都种植的马铃薯密度,以费乌瑞它为试验材料,开展了5个不同密度试验研究。结果表明:在种植密度3500～5500株/667m2范围内,随着种植密度的增加,马铃薯出苗率有降低的趋势,产量随密度增加而增加,商品薯率有降低趋势。综合经济效益方面,4500～5500株/667m2较高,均高于3500～4000株/667m2,从人工投入、物资投入综合考虑,生产上推荐应用4500株/667m2。

To explore appropriate density of potato in Shandu,taking Favorita as test materials,5 densities were applied on test.The results showed that under the density of 3500~5500 plants/667m^2,the emergency rates was decreased,the yield was increased and the marketable rates was decrease with the increase of density.As the economic benefits,the net income of 4500~5500 plants/667m^2 were greater,they were obviously greater than 3500~4000 plants/667m^2,according to labor input,materials input,4500 plants/667m^2 was proposed on potato production.
