摘要
在宁夏引黄灌区对６个草坪型多年生黑麦草品种的种子生产性能进行了研究。结果表明，不同品种间种子产量差异极显著（Ｐ＜０．０１），由高到低依次为Ｒｅｇａｌ＞Ｔａｒｇｅｔ＞Ｍｕｌｉｇａｎ＞Ｄｅｒｂｙ＞ＡＰＭ＞Ｓｅｖｉｌｅ，种子产量分别为１３８９．４、１２７９．９、１０７１．５、１０５１．７、９６３．６、６５２．６ｋｇ／ｈｍ２。因此认为，在宁夏平原灌溉条件下，多年生黑麦草种子生产以选用Ｒｅｇａｌ、Ｔａｒｇｅｔ最好，Ｍｕｌｉｇａｎ和Ｄｅｒｂｙ次之。而且，由于种子成熟期日照充足，降雨量低，故宁夏引黄灌区作为我国草坪型多年生黑麦草种子生产基地是完全可行的。
The seed productivity of 6 turf type ryegrass (Lolium perenne) varieties were studied firstly in the irrigation area of Ningxia. It was indicated that there were extremely significant differences in seed yields between different varieties (P<0.01). The order from higher to lower was “Regal”>“Target”>“Mulligan”>“Derby”>“APM”>“Seville”, with the seed yields of 1 389.4, 1 279.9, 1 071.5, 1 051.7, 963.6, 652.6 kg/hm 2 respectively. Therefore, it was recommended that “Regal” and “Target”ryegrass would be the best selection for seed production under irrigation conditions in Ningxia Plain. As a turf type seed base for perennial ryegrass production, the irrigation area of Ningxia Plain was available, because of its rich sunshine and lower rainfall during seed formation.
