The improved pixel lateral histogram algorithm was used to extract the centre of crop row. The infield adaptability of the pixel lateral histogram algorithm was enhanced by subsection computation of pixel lateral histogram.

根据条播作物行距基本恒定、作物成行排列的位置特征，利用改进的象素位置直方图法识别作物中心行，通过分段统计象素位置直方图，有效地提高了算法的田间适应度。

In recent years, the county insisted the development of agriculture as a pillar industry of edible task, they use Chinese Academy of Sciences gestos biotech companies in the group of Dr. Liang Zhirong research --- corn stalks cultivated mushrooms, so that idle in the fields of straw as food Bacteria alternative materials, in particular, the use of mushrooms, mushroom cultivation waste Huazi to develop saprophytic fungi Agaricus bisporus, Coprinus comatus was successful and achieved a turning waste into treasure.

近年来该县坚持把发展食用菌作为农业支柱产业来抓，他们利用中科院中科集团百态生物公司梁枝荣博士的研究成果———玉米秸秆栽培蘑菇，使闲散在田间地头的秸秆成为食用菌菌料的替代品，特别是利用香菇、滑子菇栽培废料来发展腐生菌双孢菇、鸡腿菇，获得成功，实现了变废为宝。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
