摘要/Abstract

摘要： 通过播前基施的措施,研究硒肥对裸燕麦果实和饲草中的营养价值的影响。结果表明,1)适当基施硒肥对裸燕麦青干草和秸秆中的营养成分影响不显著,其中合理的基施量为570～765 g/hm²,超过这个范围会显著地影响到裸燕麦青干草和秸秆中营养物质的含量,而且随着施硒量的增加,青干草和秸秆中粗蛋白质和无氮浸出物含量呈下降趋势,而粗灰分、粗脂肪和粗纤维的含量呈上升趋势,当基施量达到954 g/hm²的情况下,青干草中粗蛋白质含量降低7.34%、粗纤维和粗灰分含量分别提高5.65%(P＜0.05)和5.80%(P＜0.05),秸秆中粗蛋白质含量降低7.16%、粗灰分和粗脂肪含量分别提高5.74%(P＜0.05)和5.32%(P＜0.05),而且硒肥的影响同时具有累加效应和饱和效应。2)适当基施硒肥有利于提高裸燕麦果实的营养价值,在基施量为570～765 g/hm²的情况下,能显著提高果实中的粗蛋白含量,降低粗纤维的含量,对其他营养成分影响不显著;当施用量超过954 g/hm² 则可显著提高粗脂肪含量,显著地降低粗纤维的含量,但对粗蛋白质和无氮浸出物含量影响不显著。

Abstract: A randomized complete block design of 5 treatments with 4 replications was carried out at the Yellow River beach in Henan Province from 2008 to 2010. There were 20 plots each 7.5 m×2.0 m. The effects of basal Se fertilizer on nutrition values of forage and grain of naked oats was studied using basal Se fertilizer treatments of 0, 570, 765, 954, and 1 143 g/ha). 1) Safe amounts of Se fertilizer had no significant effect on the nutrition of hay and straw, and the safe amount to apply was from 570 g/ha to 765 g/ha. There was a significant effect on nutrition contents of hay and straw of naked oats with greater amounts. At an application rate of 954 g/ha Se fertilizer, there were significant increases of the contents of CP (crude protein), CF (crude fiber) and A (crude ash) [-7.34% (P＜0.05), 5.65% (P＜0.05) and 5.80% (P＜0.05) respectively] for hay, and increases of -7.16% (P＜0.05), 5.74% (P＜0.05) and 5.32% (P＜0.05) respectively for straw. With an increase of fertilizer amount, CP and NFE (non-nitrogen extract) decreased, while the contents of A, EE (ether extract), and CF increased. Se fertilizer had accumulation and saturation effects on naked oats. 2) Basal Se fertilizers had more apparent effects on the improvement of grain nutrition of naked oat. When application rates ranged from 570 g/ha to 765 g/ha, CP content increased significantly, but CF content decreased. When the application rate of Se fertilizer was over 954 g/ha, the content of EE increased significantly, but that of CF significantly decreased, while there were no obvious effects on the contents of CP and NFE.
