摘要
为了减少气象灾害造成的马铃薯减产,促进马铃薯种植业的增产增收,文章采用美国农业技术转化决策系统(Decision Support System for Agrotechnology Transfer,DSSAT),以山西省岚县普遍种植的冀张薯8号马铃薯为例,研究了马铃薯种植过程中实现丰产的人工影响降水方案。结果显示,大多数年份岚县的正常年降水量能够满足该地马铃薯的正常生长,进行适当的消雨作业有利于产量的增加,全年人影指数在0.4~0.8时产量增加最多;在不同的生育期之间,出苗后到开花前进行消雨作业,马铃薯增产最为明显;当发现降水量偏少而蒸散发量较往年偏大时,需要进行人工增雨或者灌溉作业。研究可为减少气象灾害引起的马铃薯减产以及促进马铃薯种植业的增产增收提供指导。
To mitigate the yield reduction of potato caused by meteorological disasters and promote the yield and income increase of potato planting,this paper uses the American agricultural technology transformation decision system DSSAT,and takes Jizhangshu 8 potato,which is widely planted in Lan County of Shanxi province,as an example to study the Artificial Precipitation Scheme in the process of potato planting.The results showed that the annual precipitation of Lan county from 2010 to 2018 can meet the normal growth of potatoes in most years,and it is generally suitable for rain suppression operation.The production can reach the largest increase when the weather index of whole year artificial influence is between 0.4 and 0.8.The rain suppression operation during the period from seedling emergence to pre-flowering has the most obvious effect on potato production increase,compared with other periods.When it is found that the precipitation is lower and the evaporation is higher than that in average years,the artificial precipitation enhancement or the irrigation is needed.The study will provide guidance for reducing the reduction of potato production caused by meteorological disasters and promoting the increase of yield and income of potato planting industry.
