燕山丘陵地区谷子灌溉影响因子的研究
Study on Influencing Factors of Millet Irrigation in Yanshan Hilly Area
摘要
Abstract
To explore the water requirement and water efficient use pattern of millet in hilly areas of Yan Mountains and provide a scientific and reasonable irrigation guarantee system for production in this region,we used the millet variety Jinmiao K1 as exper-imental crop.There were 12 treatments(G1D1,G1D2,G1D3,G2Q1,G2Q2,G2Q3,G3P1,G3P2,G3P3,G4X1,G4X2 and G4X3).The results showed that the effects of four irrigation factors on the growth and yield of millet were different.When the frequency of irrigation was 4 times(G3P3),the yield of millet was the best,with 7566.00 kg/hm2.The water use efficiency of millet under irrigation quota of 900 m3/hm2(G1D2)was the highest in the Yanshan hilly areas,with 1.94 kg/(hm2·mm).When the soil moisture content of millet farmland is more than 40%of the field water holding capacity,there is no need for supplementary irrigation.Irrigation intensity did not affect the growth and yield of millet.关键词
