Abstract : the effect of the new kind of concentrated compound fertilizer contained with herbicide on weed control and wheat growth in the wheat field was studied in the basin culture and the plot trials 文摘:通过盆钵栽培和田间小区试验，研究新型高效复配小麦专用除草药肥对麦田杂草防效和小麦生长发育的影响。
Based on current prices for corn ( 195yuan / t ) and wheat ( 145yuarl / t ) , this increase in production amounts to an extra 175 , 108 , 830 yuan for corn and 163 , 200 , 698 yuan for wheat in hebei province alone 根据当前的玉米价格( 195元/吨)和小麦价格( 145元/吨) ，仅河北省这种增产的价值就分别达到1 . 75亿元和1 . 63亿元以上。
Based on the previous screenhouse study and field experiment , fertilization , plant variety and plant density were studied on two selected cropping systems : rape - rice - rice and wheat - rice , using an orthogonality design 在过去网室研究和大田试验的基础上，在油菜-水稻-水稻和小麦-水稻两种供试种植制度上研究了施肥、作物品种和种植密度，采用正交设计。
In markets for fertilizer and for wheat , the supply and demand model does have some application ; at the same time , however , price is influenced in these examples by the oligopoly structure of the market , and by government policy , respectively 在肥料和小麦市场中，用供求模型确实可以作一些分析，但与此同时，价格又分别受到寡头独占的市场结构和政府政策的影响。

A direct comparison between soil - test based fertilization and traditional farmer practices in hebei province revealed average yield increases of 392 and 447 kg / ha for 158 corn and 30 wheat demonstrations , respectively ( jin , 1997 ) 根据在河北省土壤测试的推荐施肥和传统的农民习惯施肥的直接比较说明，在158个玉米和30个小麦示范中玉米和小麦分别平均增产392公斤/公顷和447公斤/公顷（金继运， 1997 ） 。
Maize is the main fodder grain , which is the third food crop . the other two - food crop is the paddy and wheat . but the maize lack competition in world market because our maize industry have small scale and low centrality 作为主要饲料粮的玉米在我国是仅次于水稻和小麦的主要粮食作物，但是我国的玉米规模化、集约化程度低，劳动效率低，国内玉米价格高于国际市场价格，品质又差，在国际市场上缺乏竞争力。
For the study of the relations between crops and water condition , an experimental program was carried out in 1999 and in 2000 at the agrometeorological experimental station in the nanjing institute of meteorology . seven different grades of soil moisture were kept on wheat and cotton at every stages 本文在1999年和2000年对棉花和小麦进行7个不同等级土壤湿度试验的基础上，客观地分析了棉花和小麦全生育期的耗水特征和规律，并建立了定量模拟模型。
