摘要
以谷子金苗K1为供试作物,以大水漫灌模式为对照(CK),设置了共12个处理(G_(1)D_(1)、G_(1)D_(2)、G_(1)D_(3)、G_(2)Q_(1)、G_(2)Q_(2)、G_(2)Q_(3)、G_(3)P_(1)、G_(3)P_(2)、G_(3)P_(3)、G_(4)X_(1)、G_(4)X_(2)、G_(4)X_(3)),探究燕山丘陵地区谷子需水规律及水分高效利用模式,为燕山丘陵地区谷子生产制定科学合理的灌溉保障制度。结果表明:4个灌溉因子对谷子生长及产量的影响不同,其中以G_(3)P_(3)处理(灌溉频次为4次)的产量最高(7566.00 kg/hm^(2)),以G_(1)D_(2)处理(灌溉定额为900m^(3)/hm^(2))的水分利用效率最高[1.94 kg/(hm^(2)·mm)];当谷子农田土壤含水率高于40%的田间持水率时,不需要补充灌水,灌溉强度对谷子的生长及产量无显著影响。
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 experimental crop.There were 12 treatments(G_(1)D_(1),G_(1)D_(2),G_(1)D_(3),G_(2)Q_(1),G_(2)Q_(2),G_(2)Q_(3),G_(3)P_(1),G_(3)P_(2),G_(3)P_(3),G_(4)X_(1),G_(4)X_(2) and G_(4)X_(3)).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(G_(3)P_(3)),the yield of millet was the best,with 7566.00 kg/hm^(2).The water use efficiency of millet under irrigation quota of 900 m^(3)/hm^(2)(G_(1)D_(2))was the highest in the Yanshan hilly areas,with 1.94 kg/(hm^(2)·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.
