黑龙江省北部全年低温时间较长,西部地区土地盐碱化严重,是制约黑龙江农牧业发展的两大主要因素。为了筛选出与黑龙江省气候和土壤类型相适应的牧草,本研究对从俄罗斯引进的鲁梅克斯新品种‘ЩавельЧемпион’在黑龙江省不同积温带的5个具有代表性的种植点阿城、肇州、逊克、嫩江和呼玛的农艺性状和营养价值进行研究。结果表明,该品种在肇州的生长状况明显差于其它地区,而在嫩江的生长状况明显优于其它地区;产量则表现为阿城、逊克和嫩江较高,产量均在150t·hm-2以上,肇州和呼玛略低,但产量也均在120t·hm-2以上。从营养数据可以看出,阿城种植区的粗蛋白及粗脂肪含量显著高于其它地区(P<0.05),其中粗蛋白为18.41%,粗脂肪为3.82%;肇州种植区的粗纤维含量显著低于其它地区,含量为10.75%,而粗灰分含量显著高于(P<0.05)其它各种植区,达到14.85%;嫩江种植区钙含量显著高于其它地区;肇州种植区的干物质含量显著高于其它地区。结果表明,引进新品种‘ЩавельЧемпион’适应性强,能够在黑龙江省不同区域不同土壤上种植并推广。
The northern part of Heilongjiang Province has a long period of low temperature throughout the year and serious land salinization in the western region, which is the two major factors restricting the development of agriculture and animal husbandry in Heilongjiang. In order to screen the forage grass suitable for the climatic and soil types in Heilongjiang Province, this study investigated five new representative cultivars named ЩавельЧемпион ’ЩавельЧемпион’ introduced from Russia at five different temperature zones in Heilongjiang Province, State, Xunke, Nenjiang and Huma agronomic traits and nutritional value of the study. The results showed that the growth of this cultivar in Zhaozhou was significantly worse than that in other areas, while the growth in Nenjiang was significantly better than that in other areas. The yield was higher in Acheng, Xunke and Nenjiang provinces with the yield of 150t · hm- 2 above, Zhaozhou and Huma slightly lower, but the production is also above 120t · hm-2. As can be seen from the nutritional data, the crude protein and crude fat content in the planting area of Acheng City were significantly higher than those in other areas (P <0.05), of which the crude protein was 18.41% and the crude fat was 3.82%. The crude fiber content Significantly lower than the other regions, the content was 10.75%, while the crude ash content was significantly higher (P <0.05) in other various plantations, reaching 14.85%; the calcium content in Nenjiang planting area was significantly higher than other areas; the dry matter in Zhaozhou planting area Content was significantly higher than other regions. The results showed that the new variety ’ЩавельЧемпион’ was adaptable and could be planted and popularized in different soils in different regions of Heilongjiang Province.
