摘要:

为探讨更为有效的甘薯覆膜栽培模式。采用田间试验与人工观测相结合的方法,研究不同覆膜栽培模式的生理特性和对产量的影响。结果表明:黑色地膜模式垄内10cm土壤温度平均比透明膜低2℃,比不覆盖地膜高1℃;薯块产量比透明膜高18.0%,比不覆盖地膜高20.4%。黑色地膜模式具有地温适宜、茎叶生长协调、叶面积系数合理、地上下部养分分配合理、净同化率较高的优点,这是最终薯块产量较高的原因。且不用喷洒除草剂,无污染,省工省劲。覆盖黑色地膜将成为栽培甘薯的新模式。

Abstract:

To explore a more effective film-mulching cultivation model of sweet potato.Adopting the combining method of field experiment and artificial observation to study the the effect of different cultivation modes on the physiological characteristics and yield of sweet potato.The results showed that: the temperature of black plastic film mode is 2℃ lower than the transparent film and 1℃ higher than non-covered plastic film in 10cm of soil.Ti’s Root yield is 18.0% higher than the transparent film and 20.4% higher than non-covered plastic film. Black plastic film mode have advantage of appropriate soil temperature and the growth of stems- leaves coordination and reasonable leaf area ratio and reasonable distribution of nutrients and higher net assimilation rate, which is the ultimate causes of the higher root yield. And no spraying herbicides, non-polluting, economizing labour. Black plastic film mode will be a new cultivation model of sweet potato.
