Persistence of grazing mixed pasture has been a key issue in environment conservation and sustainable utilizing of resources in karst region. Under moderate grazing with Corriedale sheep, the productivity and botanical composition of Trifolium pratense mixtures were studied over a 20-year period in karst region of southwest China. Four mixtures consisted of Trifolium pr...

用考力代绵羊轮牧，在牧前和牧后草地现存量(干物质，DM，drymatter)分别为1800~2500(草层高15~18cm)和900~1200kg·hm-2(草层高3~5cm)的适度放牧利用条件下，对亚热带最常见的豆科牧草红三叶与禾本科牧草的两两混播草地的群落生产力和持久性开展长期研究。20年的结果表明：适度放牧利用下，群落地上总生物量长期稳定，各组合间差异不显著，总盖度20a后仍高达97%以上；适度放牧有利于牧草的生产力持久性，红三叶、鸭茅、多年生黑麦草和黑穗画眉草都在群落中长期存在；群落净产量和持久性是尺度依赖的，群落长期净生产力以红三叶+鸭茅的最高(DM产量353.3g·m-2·a-1)(P.05)，对杂草侵入的抵抗力最强，而前10a红三叶+多年生黑麦草有很高的净生产力DM产量449.8g·m-2·a。。。

Rice is the most importance cropper in the world, it is widelyaccepted as the model of the gramineae and monocotyledon.

The total effective rate against corn field grass family , dicotyledon , cyperaceae weeds can be higher than 86 , and it is safe to corn and soybean crops .

本发明悬乳剂提高了防效，扩大了乙草胺和阿灭净的防治谱，对玉米田禾本科，双子叶，莎草科杂草的总防效达86％以上，而且对玉米，大豆等作物使用安全性好。

Benzoxazine compounds are one kind of highly active protoporhyrinogen oxidase inhibitors. These compounds can effectively control both monocotyledon weeds and dicotyledon weeds at lower dosage. The action mechanism is similar to p-nitro-o-substituted diphenylethers. They can result weeds albinism and decolorization, which are very important albinism herbicide.

苯并噁嗪类化合物是一类高活性的原卟啉原氧化酶抑制剂，低剂量可有效地防除禾本科与阔叶杂草，其作用机理和对硝基邻位取代的二苯醚类似，它们造成白化或脱色，是白化除草剂中较重要的种类，其活性远超过二苯醚除草剂，是目前化学农药研究领域的热点。

In dicotyledonous and nongraminaceous plants, NAS synthesizes nicotianamine which is responsible for iron storage and transportation, and the expression of NAS gene is not induced by iron deficiency.

在双子叶和非禾本科单子叶植物中，烟酰胺的主要功能是铁离子的储藏和运输，NAS基因的表达不受缺铁胁迫诱导。

The weed community was composed of monocyledonous weeds and dicotyledonous weeds with barnyardgrass as its main part.

结果表明，禾本科杂草和石竹科杂草是烟稻轮作烟地的主要恶性杂草，其群落结构是单子叶杂草和双子叶杂草组成的混合群落。
