宁夏扬黄灌区马铃薯水分生产函数试验研究
|
摘要
为确定宁夏扬黄灌区马铃薯水分生产函数,以"克新一号"马铃薯为供试品种,采用膜下滴灌的方式,以不同生育期土壤水分水平为试验因素,对马铃薯不同生育期进行调亏灌溉,测定土壤含水率、耗水量、产量,研究不同生育期不同水分亏缺处理对作物耗水量和产量的影响,并对5种常用的作物水分生产函数建模分析。结果表明:马铃薯块茎形成期轻度水分亏缺处理及淀粉积累期轻度、中度水分亏缺处理对产量影响不显著,块茎形成期和块茎膨大期中度水分亏缺处理及块茎膨大期轻度水分亏缺处理对其产量影响显著;建立Jensen模型、Minhas模型、Stewart模型、Blank模型和Singh模型,根据获得的数据和模型分别求取水分敏感指数。通过分析,水分亏缺会造成马铃薯不同程度的减产,Jensen模型更适用于宁夏扬黄灌区马铃薯的需水情况。
To determine the potato water production function in Yellow River Pumping Irrigation Area of Ningxia,the experiment was performed by using water deficit irrigation in different growth periods of potato to study the effects of soil water conditions on water consumption and yield at different growth period of potato. The field soil water content,water consumption and yield with drip irrigation under mulch were measured,and the"ke xin yi hao"was used as the test material. The results showed that: potato yield did not decrease under low water deficit condition during tuber initiation period and under low and medium water deficit condition during starch accumulation stage,but decreased significantly under medium water deficit condition during tuber initiation period and under low and medium water deficit condition during tuber initiation stage. Jensen model,Minhas model,Blank model,Stewart model and Singh model were established to analyze the consumed water quantity and the yield of maize under different irrigation quantity. According to the obtained data and the models,the moisture sensitivity index was calculated. The analysis result indicates that the water deficit results in different degrees potato yield reduction. The Jensen model is more suitable for water requirement calculation of potato in Yanghuang irrigation area of Ningxia.
