摘要
为了筛选出适合科尔沁沙地种植的优良饲用高粱品种,试验对科尔沁沙地8个饲用高粱[Sorghum bicolor(L.) Moench]品种的农艺性状、草产量和营养指标进行测定和分析。结果表明:各品种的分枝数范围为5. 33~6. 66个,株高变化范围为343. 40~425. 73 cm,茎粗变化范围为15. 77~28. 22 mm,鲜草产量变化范围为105. 92~207. 77 t/hm^2,干草产量变化范围为42. 25~82. 62 t/hm^2;品种BJ0602的粗蛋白(CP)含量最高(21. 26%),品种2180的CP含量最低(14. 76%);各品种的相对饲喂价值(RFV)均大于100,其中品种N52K1009、BJ0602、BJ0603、1230的RFV较高,而品种1220和N5212274的RFV较低。综合考虑,品种1230和N52K1009的鲜草和干草产量较高,同时RFV较高,可以制作干草或青贮饲料;品种BJ0602和BJ0603的RFV较高,但产量较低,可以作为青饲利用;品种1220和N5212274的产量较高,但RFV较低,可以作为青贮饲料。
In order to screen fine forage sorghum varieties cultivated in Horqin sandy land, eight varieties of forage sorghum[Sorghum bicolor(L.)Moench] were chosen in this experiment for the measurement and analysis of agronomic character, grass yield and nutritive index. The results showed that branching numbers of each variety varied in 5. 33 to 6. 66,with plant heights in 343. 40 to 425. 73 cm,stem thickness in 15. 77 to 28. 22 mm,fresh grass yields in 105. 92 to 207. 77 t/hm^2 ,and hay grass yields in 42. 25 to 82. 62 t/hm^2. Crude protein content of BJ0602 variety was the highest(21. 26%) , while that of 2180 variety was the lowest( 14. 76%). The relative feed values( RFV)of each variety were more than 100,among which RFV of N52K1009, BJ0602, BJ0603,1230 varieties were higher,and those of 1220 and N5212274 varieties were lower. Under comprehensive consideration, 1230 and N52K1009 varieties had higher fresh grass yields and hay grass yields,and also had higher RFV , which can be chosen to make hay or silage;BJ0602 and BJ0603 varieties had higher RFV but lower grass yields,which can be chosen to make green feed; 1220 and N5212274 varieties had higher grass yields but lower RFV,which can be chosen to make silage.
