According results of field experiments, N 448.5, P2O5 52.5 kg/hm^2, K2O 180 - 270 kg/hm^2 and N- P2O5 - K2O 1:0.12:0.40 - 0.60 was optimum balance fertilization scheme, and organic complex fertilizers with inorganic fertilizer used were recommend for rareripe taro to obtain high yield and profit.

通过两年芋艿施肥田间试验，表明获得早熟芋艿高产、高效的施肥方案为N448.5kg／hm^2，P2O5 52.5kg／hm^2，K2O 180-270kg／hm^2，N-P2O5-K2O比例为1：0.12：0.40-0.60，并推荐有机无机复合肥与化肥配合施用，以获得更高的产量和效益。

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。

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。

"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。
