2014—2015在陕西三原县安乐镇西毛村试验基地进行了不同肥料处理对中麦895小麦产量及品质的影响研究.试验结果表明,使用不同复合肥较常规施肥处理产量显著提高,增产10.5%～13.4%,以中化复合肥处理增产幅度最大,达13.4%.使用复合肥可显著提高小麦个体质量,其中单株分蘖数和次生根数分别较对照提高1.7%～15.4%和11.5%～17.9%;成穗率和成穗数分别较对照提高7.9%～11.9%和11.4%～16.7%;但对穗粒数、千粒重、穗长、小穗数和不孕小穗数效应不显著.施用复合肥可显著提高小麦籽粒稳定时间、沉降值、容重、拉伸面积和最大拉伸阻力,依次较对照增加15.6%～19.4%、3.1%～4.6%、0.6%～1.1%、2.1%～4.2%和0.5%～0.8%,但对籽粒蛋白质含量、湿面筋含量、硬度和吸水率的影响不明显. 相似文献

该试验以露地栽培的菠菜为材料，探讨了有机肥与NPK复合肥配施对菠菜营养元素含量的影响．结果表明5种施肥处理中最佳施肥处理为半量虫粪(3500Kg／hm^2)与50％NPK配施，可显著提高菠菜中N、P、K、Fe、Mn等元素含量，降低Cu、Zn等重金属离子含量．还可以提高菠菜的产量，同时增加了土壤肥力． 相似文献

通过对香料烟不同有机肥配方试验进行生理生化测定研究,初步探明成熟烟叶内的NR,POD,PPO活性及MDA,Pro,比叶质量含量变化规律：配施有机肥对NR,POD活性及丙二醛、比叶质量含量有增大趋势,对PPO活性和Pro含量有减少的趋势;单施复合肥和芝麻饼肥、桐油枯＋复合肥的成熟烟叶内,Chlb的含量较高,类胡萝卜素的含量较高,Chla／Chlb、叶绿素／类胡萝卜素的比值较低． 相似文献

采用室内恒温好气培养法,通过在土壤中添加复合肥、枯落物和牛粪,探讨不同添加物对冬枣林模拟土壤氮含量及矿化量的影响。结果表明,培养过程中,除对照外,添加复合肥土壤的NH4^＋-N含量最高,枯落物次之,牛粪最低（P〈0.05）;不同处理土壤NO3^--N含量的变化不显著（P〉0.05）,氮素矿化量差异显著（P〈0.05）,表现为复合肥处理〉枯落物处理〉牛粪处理〉对照;其中对照土壤的氮素矿化量呈负值,无机氮随时间而消耗;不同添加物处理的土壤氮矿化量为正值,表明添加物的施加促进了土壤氮的矿化过程,因此,在冬枣栽培区施肥管理中,可探讨按照适宜比例施加复合肥、枯落物、牛粪和农作物的秸秆,以促进土壤中氮的转化与有效利用。 相似文献

本试验采用我校自行研制的由宁波有机-无机复肥厂加工的马铃薯的一次性基施专用肥。在1996年春、秋二季试验的基础上。于1997年继续对春马铃薯进行专用肥施用技术的探索。试验结果表明,专用肥可明显提高马铃薯的产量,品质,促进土壤微生物的繁育,增加苗落量,加速土壤养分分解,转化,改善土壤理化性状．其中M-2的效果更佳。马铃薯专用肥的施用宜在播前半月左右进行。 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity. 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献
