俄罗斯引进鲁梅克斯新品种在黑龙江省的推广种植

Planting evaluation of new Rumex varieties introduced from Russia in Heilongjiang Province

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 low temperature time is long in the northern part of Heilongjiang Province,and the land salinization in the western region is serious,which are two main factors that restrict the development of local agriculture and animal husbandry.In order to obtain forage adapting to the climate in Heilongjiang province and soil types,weevaluated agronomic characters and nutritional value for the new Rumex species＂ЩавельЧемпион＂imported from Russia in five representative planting plotsrepresenting different accumulated temperature zone in Heilongjiang province such as Acheng,Zhaozhou,Xunke,Nenjiang and huma.The results showed that the growth status of the species in Zhaozhou was significantly lower than other regions,while it grownbetterin Nenjiang than other regions.The biomass was more than 150t/hm2 in Acheng,Xunke,Nenjiang,but slightly lower in Zhaozhou and huma,which were also above 120t·hm^-2.The nutritional data showed that the crude protein and crude fat content of samplesfrom Achengwere significantly higher than other regions（P〈0.05）,the crude protein was 18.41% and crude fat was 3.82%;The crude fiberof samples in Zhaozhou was significantly lower than other regions（P〈0.05）,and the content was 10.75%,while crude ash contentwas significantly higher than that of other planting areas（P〈0.05）,reaching 14.85%;calcium and water content in Nenjiang and huma respectively was higher than the other areas but did not reach significant level.The results showed that new variety‘ЩавельЧемпион＇has a good adaptability,which can grow in differenttypes of soil,and in different regions of Heilongjiang Province.
