摘要
通过该项研究表明 :内蒙古夏莜麦栽培区裸燕 32 3的鲜草和籽实产量分别比对照 (1)增产 4 5 .6 %～6 7.7% ,比对照 (2 )增产 5 3.5 %～ 2 6 .3% ;裸燕 82比对照 (1)增产 4 1.7%～ 0 .4 % ,比对照 (2 )增产 4 9.1%～2 4 .4 % ;将 1季改 2季栽培平均鲜草产量达 1390 5 6 kg/ hm2 ,比单季作增长 1倍 ;在云南省冬季南繁中 ,在缩短日照条件下营养生长期加长 ,产草量更增大 ;在内蒙古冷凉秋莜麦区 ,裸燕 32 3比对照 (1)增产 12 5 % ;在秋莜麦 (高寒 )区裸燕 82比对照 (1)增产 2 9% ,均表现适应性强 ,是粮草兼用的新品种 ;其营养成分高于对照种和玉米 ,是质优的饲用作物为养殖业奠定了物质基础 ;饲用后 ,每头牛日增奶量 2 .13kg,年增值 186 1.5元 /头 ,栽培技术简便、成本低 ,减轻了农民投入和负担 ,增加的经济效益显著 ,是适宜推广的新品种。
Elonomical characters and usage of New variety of Naked oat was studied,the results showing,in summer growng area of Inner Mongolia,the grass yield and seed yield of Naked Oat 323 increases 45.6% ～67.7% comparing to the check variety(CK) I and increases 53.5%～26.3% comparing to ckⅡ;while that of Naked Oat 82 increases 41.7%～0.4% comparing to CK I and 49.1%～24.4% comparing to CKⅡ;The average grass yield is 139056 kg/hm 2 in the double-seasonal cultivating method,which is two times to that of single-seasonal cultivating method;The grass yield increased more in southern china than in Inner Mongolia due to the short of daily sunshine;In cool area,the yield of Naked Oat 323 increases 125% comparing to CK I;the yield of while Naked Oat 82 increases 29% comparing to CK I.It was suggested the new varieties have good adapting ability,and dual usage of crop and grass;Its nutrition is higher than CK and silage corn;It is a good quality forage. Feeding result shows,milk yield increase 2.13kg per day,the year income increases 1861.5 yuan per cow.The new varieties is suitable to spread because of the simple cultivating technique,low cost and high repayment.
