Five nitrogen concentrations including 0 mg/L,150 mg/L,300 mg/L,450 mg/L and 600 mg/L were sprayed on the root of D.styracifolium in field to study the effects of different N concentration on gas exchange,chlorophyll content,soluble protein content and nitrate reductase activity in leaves of seedlings.

采用田间试验的方式，设0mg/L，150mg/L，300mg/L，450mg/L和600mg/L5个N浓度处理，研究其对广金钱草苗期叶片气体交换、叶绿素含量、可溶性蛋白含量和硝酸还原酶活性的影响。

The effect of pesticides on field controlling root rot of Vicia faba was studied in two consecutive years by seed treatment of fungicides and their combination.

在实验室内探讨了三唑酮、甲基硫菌灵、福美双、恶霜灵和甲霜灵等 5种杀菌剂单用或混用对蚕豆种子萌发和幼苗生长的影响。据此，在田间开展了杀菌剂拌种和杀菌剂与杀虫剂混用防治蚕豆根腐病的研究。

In the 50 cm plough layer per m2 area, the total rootstalk weight of L.

结果表明：赖草株高45~120 cm，单生或丛生，具下伸土壤30~50 cm耕层间有横走根群，每平方米内，深50 cm耕层内赖草根茎总重量为1129.3 g，根茎总长度为2783.3 cm，根茎上的新芽589.7个，使土壤严重缺水，肥力下降；土壤水分在13.4%左右时，对出苗影响不大，对生长发育有很大的影响；气温在-6~6℃，根茎萌发出土，高峰期为4月上旬，平均单株结种量为468.4粒；每平方米内有赖草120~160株时，大黄产量损失达15.8%~17.8%；田间每平方米内有赖草1株时，采用人工或机械深耕捡出地下根茎，减轻翌年危害来源。

The soil infiltrability is influenced by slopes and soil circumstances in field and the Linear Run-on Method was used to measure soil infiltrability in the field.

为分析坡度和土壤环境对土镶入渗性能的影响，采用线源入流测量法对田间土壤的入渗性能进行试验研究。

Most field isolates are self-fertile, producing many fruiting bodies called perithecia on the surface of the substrate or in culture.

大多数田间菌株是自交能孕的，在基质或培养物的表面上产生许多子实体称子囊壳。

Field experiment was conducted to investigate the applying effect of biology silicon fertilizer to the soil fertility on serosity soil.

通过田间试验研究了在白浆土上施用生物硅肥的对土壤肥力的影响。

"For example, recently in Nanjing Shimao Shimonoseki area, took a large piece of land, the market reaction was very unexpected, but in fact the end of last year we began doing detailed research and field demonstration."

说： "例如，最近在南京世茂下关区，采取了一大片土地，市场的反应是很意外，但事实上，去年年底我们开始做详细的研究和田间示范。"

Aphids in the process of inhaling plant sap virus particles and auxiliary proteins also be inhaled, thus completing the process by poison, which also supports the field citrus aphid is non-persistent decline disease vector of disease, while the citrus Huanglongbing is phloem restricted by the bacteria caused the main pathogens present in the phloem, the fleas only by phloem feeding in diseased plants, pathogens in the body through the back to complete the salivary glands in the course of the next through the sieve tube feeding in the secretion of saliva the pathogens into the healthy tree, Citrus Huanglongbing different characteristics with aphid-borne diseases, Huanglongbing to persistent disease.

蚜虫在吸入植物汁液的过程中病毒粒子和辅蛋白同时也被吸入，从而完成获毒过程，这也支持了田间蚜虫是柑桔衰退病等非持久性病害传播介体，而柑桔黄龙病是由韧皮部限制性细菌类引起，病原体主要存在于韧皮部中，木虱只有通过在病株韧皮部取食，病原在体内完成循回到唾液腺中，在下一次取食过程中通过在筛管中分泌的唾液将病原体带到健树，柑桔黄龙病与蚜虫传病特点不同，黄龙病为持久性病害。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
