本试验目的在于评价红豆草和苜蓿的生产能力及营养价值。第二年盛花期红豆草的干草产量比苜蓿高30%,蛋白质高13%,14种氨基酸的含量也高于苜蓿。红豆草花期的落叶量少,茎较柔软,含有2~3%的丹宁,不会引起鼓胀病,但适口性较苜蓿差.鲜草饲喂生长肉兔的效果不如苜蓿,草粉配合料饲喂肥育兔的效果相近;压缩颗粒料饲喂生长肉兔的效果差异不显著.在绵羊试验中,结实期红豆草粉配合料的采食量比苜蓿的高14%,日增重高17%;盛花期分别高10%和27%.两种牧草对兔和绵羊的消化能差异无几.
The purpose of this experiment was to evaluate the productivity and nutritional value of sainfoin and alfalfa. The second year full-flowering sainfoin hay yield 30% higher than alfalfa, protein 13%, 14 amino acids content is also higher than alfalfa. Red bean flowering season less deciduous, softer stems, containing 2 to 3% of tannin, will not cause bulging disease, but palatability worse than alfalfa. Fresh grass rabbits fed growing effect than alfalfa, meal mix Feeding rabbits with similar effects; compressed pellets feeding rabbits showed no significant difference in the effect of sheep.In the sheep experiment, the roasted red bean powder compound feed intake 14% higher than alfalfa, high daily gain 17 %; Full flowering were 10% and 27%, respectively, and there was no difference in digestibility between the two forages for rabbits and sheep.

试验于2006—2007年在河北农业大学植物标本园进行。选用河北省农科院粮油所培育的04年国审早熟品种冀红8937为材料。在田间和室内分别进行了观测,研究小豆全株不同节位相同花位、同一序节不同花位小花分化速度的差异与花荚形成及脱落的关系,主要研究结果如下:1、花芽分化进程与主茎复叶数之间具有同伸性。出苗后9d开始花芽分化,肥大的腋芽原基首先出现在主茎和第1个一级分枝腋部混合芽的第1、2节上;4~5

摘 要:如何在教学中有效应用信息技术,促进和深化教学改革,提高教学质量,推进教育信息化的进程,已经成为一个迫切而重要的课题,不少人都在思考和实践这个课题。出路何在?笔者认为,关键是加强理论修养,跳出当前孤立、静止地看待“整合”中信息技术与教学这两个要素关系的思维模式,创新“整合”教学。 关键词:信息技术;学科教学;整合;理论修养;创新 中图分类号:G434文献标识码:A 文章编号:1673-8

尽管钴(Co2+)在高等植物中为非必需元素,但其对豆科植物有益。然而,植物组织中过量Co2+会对细胞和细胞膜引起不可逆损伤,导致产量、生物量减少、酶失活甚至植株死亡。防止植物中Co2+积累以降低人类饮食中的Co2+含量从而减轻与Co2+相关的健康风险,最经济有效和高效的方法是培育抗Co2+作物或品种。此外,植物中Co2+积累和毒性在不同品种和基因型间差异很大。本研究旨在:(1)明确大麦基因型Co2
