The results showed: the content of dissoluble substance, pectin, hemicellulose, lignin and cellulose in straw is 16.57%, 7.82%, 19.4%, 18.4% and 21.01%, respectively; the decrease rates of pectin, hemicellulose and lignin in retied stems are 82.10%, 17.01% and 11.40%, respectively; the content of dissoluble substance in flax stems has dropped rapidly from 16.57% to 7.93% in the first two hours of fermentation; the increase rates of bacteria number in the second two hours is 588%, which is the biggest in this process; the content of pectin, hemicellulose and lignin in flax stems will be declining with the retting going on.

结果表明，亚麻原茎中水溶物、果胶、半纤维素、木质素和纤维素含量分别为：16.57%、7.82%、19.4%、18.4%和21.01%；脱胶完成时，果胶、半纤维素和木质素脱除率分别为82.1%、17.0%和11.4%；在接种后发酵2h内，亚麻麻茎中的水溶物由16.57%迅速降至7.93%；接种后发酵2h- 4h，脱胶菌活菌量的增加幅度最大，为5.88倍；麻茎中果胶、半纤维素和木质素的含量均随着时间的延长而降低。

At present there are 2 species of pest damage to pear trees including Janus gussakovskii and J.piri in Tianshui city.

目前在天水市为害梨树的茎蜂虫种有古氏简脉茎蜂和梨简脉茎蜂2种。

The result showed that not only the seed-stem germination of XinXuan048 and ZM8316 was earliest but also the germination rate highest,the rooting power strongest ,the growth of seedlings rapidest and the chlorophyll content of seedlings leaf highest .

结果表明，新选048、ZM8316种茎发芽最快，发芽整齐，发芽率高，种茎可溶性糖含量最高，发根力强，根数多，根系活力强，幼苗茎叶生长快，叶片叶绿素含量高；其次是辐选01、华南124和新选056。

Result It was confirmed as a reasonable population when the total stem number of wheat in reviving stage was lower than the mature spike number, the shuttle-shaped plant form at the stage of maximal population, and the leaf area coefficient in flowering stage was 4. Soil fertility had significant influence on the growth of wheat stems and leaves at early stage and had certain influence at middle-late stage. Density influenced the growth of stems and leaves before the formation of the largest population, while it had little effect after flowering.

结果］冬小麦起身期的总茎数略低于成穗数，群体最大时期株型呈现梭形，开花期叶面积系数为4是较为合理的冠层结构；土壤肥力对小麦前期的茎、叶生长影响显著，在中后期也有一定的影响；密度则在形成最大群体前影响茎叶的生长，到小麦开花后影响不明显。

The thickness of surface layer,thick angle tissue and vassular tissue were raised and the invasion and growth of Alternaria solani were hindered after applying K fertilizer,therefore the breaking－out time of the disease were delayed 3-4 d.Thus,the incidence of tomato early blight dropped.

32.0%和12%？22%。番茄茎角质层明显，厚角组织、维管组织厚度增加，占茎总横断面积比增大，细胞壁增厚，延缓茎发病时间3-4d，阻碍番茄链格孢菌的侵入和生长，使番茄早疫病发病率降低。

In order to research the sugar accumulating regulation of sweet sorghum, the relationship between the brix of every internode and average brix of its whole stem was studied. This paper used varieties MNS-1, MNS-2 and stem brix of sweet sorghum in different period. The result showed that the variation of early matured and late matured varieties of sweet sorghum had same tendency in brix in same growing period, but had different values.

为了解甜高粱茎秆中糖分积累规律，研究甜高粱自基部至顶部各茎节间锤度关系及各茎节锤度与主茎秆平均锤度的关系，以示范推广品种MNS-1、MNS-2为材料，测量了不同时期甜高粱的茎秆锤度值；采用相关等分析方法对各茎节间锤度及与主茎秆平均锤度的关系进行分析。

G. cutting roots from 4 surface on the position 20cm away from the stem base nor cutting roots too near from stem base e.

若断根数量太多（如距茎20厘米处4面断根），或断根位置距茎基部太近（距茎基部10厘米处1面或4面断根），都不利于叶片含钾量提高

Bobai is characterized by water spinach planted paddy fields, dense leaf stem length, leaf tail taper,鲜绿crisp, the stem pick into a paragraph break, the fracture that split kink, with a sharp knife could not cut the stem I ping.

博白蕹菜的特点是水田栽植，茎长叶密，叶尾尖细，鲜绿脆嫩，把茎蔓摘断成段，其断口即裂开卷缩，用锋利的刀也无法将茎口切平。

The results showed that the variance in stem shearing force of Alfalfa and rye grass are due to a combination of factors, including changes in chemical composition, morphological characteristics. DM and NDF degradability of alfalfa stem had negative relationships with shearing force. Shearing force could be used as an indicator of forage stem nutritive value.

对于盛花期紫花苜蓿及灌浆期冬牧70黑麦草，茎剪切力受形态学指标、化学组成的综合影响；紫花苜蓿茎剪切力与DM、NDF48h瘤胃降解率之间存在显著负相关，因此可用剪切力估计紫花苜蓿茎养分降解率的大小。

The lesions are dark brown, water-soaked, and girdle the stem, causing the stem to collapse and die.

茎部病灶为黑褐色、水浸状且环绕茎部时会引起茎部枯萎死亡。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
