微型薯粒重与密度对秋繁原种产量及性状的影响
Effects of Mini-potato Weight and Planting Density on Yield and Yield Characters of Original Seed Potato Reproduced in Autumn
【摘要】 为探明马铃薯脱毒微型薯在安顺市秋季扩繁生产中的性状表现及适宜播种密度,以不同粒重微型薯为主处理,密度为副处理进行裂区试验,探讨了微型薯粒重与密度对秋繁原种产量及性状的影响。结果表明:在中薯3号原种扩繁中,1~5 g微型薯播种密度以8 500~9 000株/667m2、5 g以上以6 500~7 000株/667m2为宜。
【Abstract】 The split block design was used in mini-potato reproduction of Zhongshu 3 in autumn to study the effects of mini-potato weight and planting density on yield and yield characters.The results showed that the optimum planting density of mini-potato wich weighed 1~5 g and more than 5 g were 8 500~9 000 plants/667m2 and 6 500~7 000 plants/667m2 respectively.
