摘要
为了探明微润灌溉青椒最适宜的技术参数,采用熵值—TOPSIS—灰色关联度模型对青椒生长发育的各项指标进行了综合评价。进行了管带埋深为10 cm(D10)、15 cm(D15)、20 cm(D20)和压力水头为100 cm(H100)、150 cm(H150)、200 cm(H200)条件下的微润灌青椒生长试验。结果表明:不同管带埋深处理后的青椒各项单指标均表现为D20>D15>D10。不同压力水头处理后的株高、茎粗及产量表现为H150>H200>H100,株高生长速率和茎粗生长速率表现为H200>H150>H100,灌溉水生产率表现为H100>H150>H200。选择的指标不同,得出的最佳微润灌溉技术参数也不相同。采用熵值—TOPSIS—灰色关联度模型分析微润灌对青椒生长影响得出:当压力水头一定时,综合贴近度随着管带埋深的增大而升高;当管带埋深一定时,综合贴近度会随着压力水头的增大先升高后降低。青椒微润灌最适宜的技术参数为:压力水头为150 cm,管带埋深为20 cm。
In order to find out the most suitable technical parameters of moistube irrigation green pepper,the entropy—TOPSIS—grey correlation model was used to evaluate the growth and development of green pepper.The growth test of moistube irrigated green pepper was carried out under the conditions of buried depth of 10 cm(D10),15 cm(D15),20 cm(D20)and pressure head of 100 cm(H100),150 cm(H150)and 200 cm(H200).The results showed that the single indexes of green pepper treated with different pipe belt depths were D20>D15>D10.The plant height,stem diameter and yield after different pressure head treatments were H150>H200>H100,the plant height growth rate and stem diameter growth rate were H200>H150>H100,and the irrigation water productivity was H100>H150>H200.The selected indicators are different,and the optimal moistube irrigation technical parameters are also different.The entropy—TOPSIS—grey correlation model was used to analyze the effect of moistube irrigation on the growth of green pepper.When the pressure head is constant,the comprehensive closeness increases with the increase of the buried depth of the pipe belt.When the buried depth of the pipe is constant,the comprehensive closeness will increase first and then decrease with the increase of the pressure head.The most suitable technical parameters for moistube irrigation of green pepper are as follow:the pressure head is 150 cm,and the buried depth of the pipe belt is 20 cm.
