8个国外引进紫花苜蓿品种的产量性能分析

Analysis on the Yield of Eight Introduced Alfalfa Cultivars

为河北省东部沿海农区乃至河北省的苜蓿种植者科学选择优良苜蓿品种,以国外引进的8个紫花苜蓿品种为试材,2009～2011年在河北省东部沿海农区的典型代表地域——沧州市前营村沧州市农林科学院试验田连续进行了3 a田间试验,从年株高、年平均产量(干重)和各茬次平均产量(干重)3个方面,对不同苜蓿品种的产量性能进行了分析和综合评价。结果表明:参试品种中,年平均产量居前3位的苜蓿品种是Queen、BARALFA54和美国大叶,干草年均产量分别为14.3 t/hm2、14.2 t/hm2和14.1 t/hm2;同一品种,不同茬次的产量存在显著差异(P<0.05),其中,第1茬产量最高,占全年总产量的33%以上,第4茬产量最低(占年总产量的比例不足20%)。Queen、BARALFA54和美国大叶在河北省东部沿海农区种植综合表现较好,适合作为该区种植高产苜蓿品种的选择。

In order to select the appropriate alfalfa cultivars for planter in eastern coastal area of Hebei Province, consecutive 3 years field experiment was conducted to analysis and evaluate the yield performance of eight introduced alfalfa cuhivars from 3 aspects of annual plant height, annual dry matter yield and annual dry matter yield of every stubble from 2009 to 2011 in Qianying Village of Cangzhou City Cangzhou Academy of Agriculture and Forestry Sciences test field. The results showed that the top three cuhivars with the highest annual dry matter yield were Queen （ 14. 3 t/hm2 ） , BARALFA54 （ 14. 2 t/hm2 ） and Leafking （ 14. 1 t./hm2 ） , respectively. There were significant differences in dry matter yield of different stubble of the same variety （ P 〈 0.05 ）, and the first stubble had the highest dry matter yield and obtained more than 33 percents of annual dry matter yield, the fourth stubble got the lowest yield and were less than 20 percents of annual dry matter yield. Queen, BARALFA54 and Leafking were suitable to be cultivated in eastern coastal area of Hebei Province.
