脱毒微型马铃薯种植密度对一级原种产量的影响
Effects of Planting Density of Virus-free Mini-potato on Yield of First Original Seed Potato
摘要
Abstract
A comparative study on effect of 4 planting densities of virus -free potato with 2.5~5 g weight on yield of first original seed potato was conducted.The results showed that the yield and quantity per m 2 of seed potato were highest , 16 404.0 kg/hm2 and 147.2 grain/m2 respectively , when the density was 135 000 plants/hm2.When the density was 120 000 plants/hm2 ,there had the highest yield per plant and the maximum grain number per plant ,235.2 g and 12.1 grain per plant respectively.The economic benefit of the above two densities was equivalent.So 120 000~135 000 plants/hm2 was suitable for propagating seed potato with 2.5~5 g mini-potato.关键词
