红缨张晓华红缨在农村经常可见，它最重要的用途是装饰高骡大马。红缨的构造并不十分复杂，只要把麻劈成缕缕细丝，染成红色，剪裁整齐，扎成大把、小把就行了。小把的叫红缨花，大把的叫火把花。在骡、马的鞍子上、扇尾上，栽上一朵红缨花，额头上扎上一炬火把形的红缨絮，像火红的榴花，像一片朝霞。它是美的象征。骡、马头上扎一朵红缨，在行进中，眼前似乎燃烧着一团火。它能热了马的心，提起骡的神，使它们越走越带劲，越走越精神。它是军列前边迎风招展的“旗帜”。当骡、马行进在大道、公路上，自行车、拖拉机、汽车川流不息，熙熙攘攘，这时它们头上的红缨来回摆动，可以分散注意力，减少外界的干扰，避免受惊发生意外。它是定神静心的“安神丸”。烈日炎炎的盛夏，潮湿闷热的秋天，那苍蝇、蚊子，讨厌的小昆虫，时常封锁道路，在骡、马的眼前飞来舞去。这时那红缨随着牲口的头来回摆动，上下左右驱赶着，扑打着这些小玩意儿，保护它的主人不受其害。它是一把理想的“扇子”。当人们光景富裕，日子红火时，为了图个喜庆，总要把那高骡大马打扮一番，所以红缨就成了必不可少的装饰品。它是一朵“富”字花。红缨，虽然很普通，但是它却象征了我们这个黄金时代，象征了当代农民的富丽年华。我们说，立意要情意并重，本文是否做到了这一点 作者在文中表达了怎样的感情
下列植物生理的理论研究成果，是生物化学调控技术的依据。 (一)植物根茎叶的表面可以吸收具有生理活性的有机物质。这些物质一进入植物体内就可随维管束的筛管液流与导筛水流传布周身。植物的这种特性给农用药剂大开方便之门。原来需要从根系吸收的矿质元素中，有些元素易被土壤固定，因而不容易被植物吸收利用，若采用溶液喷射的根外追服，就能解决这个问题。此外，农用药剂可以“内服”——注射法，并能在体内转移与保留。一向“外敷”用作保护层的除害药剂，只能对覆盖的枝条有效，用量大，期限短。二者比较起来，已不可同日而语。 (二)溶液培养植物成功，确定了营养代谢所需的水分与必需的矿质元素的性质和数量，成为合理、定量灌溉与施肥的依据，并给无土栽培作出了榜样。自然资源在太阳的操纵下，不仅供给植物生活的能量，还给植物个体发育提供必需的生态环境。再通过植物体内部的相互影响，植物的遗传性状才能实现。植物为了维持生存，依靠感应来适应气候中光、温和季节周期的变化，以及逆境的胁迫。植物常在敏感部位受到刺激后，便发出信使在体内传递，影响效应部位反应出来。研究发现，这些信使是激素一类的生物化学物质，它们的生理活性强，功能各异，化学结构比较简单，可以人工模拟与批量合成。无论是内原激素，还是人工调节剂，在植物上微量施用，就会启发显著的生理变化。 “自然资源在太阳的操纵下”指的是（ ） 水分、矿质元素在日照下产生能量，造成特定环境。植物从日照中获得能量和必需的生态环境。 气候中，光、温和季节周期性的变化。日照对植物实现遗传性状所具有的决定性的作用。A.水分、矿质元素在日照下产生能量，造成特定环境。B.植物从日照中获得能量和必需的生态环境。 C.气候中，光、温和季节周期性的变化。D.日照对植物实现遗传性状所具有的决定性的作用。
