查询词典 leghorn straw

Determination of photosynthetic pigments used 80% of acetone extraction method directly and the photosynthetic characteristics of using Li-6400 portable photosynthesis detector. Results showed that Returning the right amount maize straw stem into field was able to significantly restraint this year winter wheat flag leaf Chla degradation, to raise the flag leaf Chla/Chlb in the watery metaphase and late stage, to effectively restraint the photosynthesis rate decrease in the watery stage, to increase the pertinence of photosynthesis rate and pigment compared to others. However returning more maize straw stem into field was able to accelerate the retrogradation of chlorophyll and photosynthesis rate decrease then the yield declined.

结果表明：适量的玉米秸秆还田(9 000 kg/hm^2)可显著抑制接茬冬小麦灌浆中后期旗叶Chla降解，提高小麦灌浆中后期旗叶Chla/Chlb的比值，有效抑制灌浆期旗叶光合速率的下降，与其他处理相比，其光合速率与叶绿素的相关性得到加强；过量的秸秆还田(15 000 kg/hm^2)，加速了光合色素的降解，使得光合速率下降，产量降低；在各处理中，处理Ⅱ(9 000 kg/hm^2)产量最高。

But when it came to different summer-sown maize, the straw of normal summer-sown maize absorbed less nitrogen absorption than grain did, while the straw of high oil summer-sown maize absorbed more nitrogen absorption than grain did. This it to say, high oil summer-sown maize need more nitrogen, when use N2, the nitrogen redundance was not happened, not like normal summer-sown maize.

但就各器官来说，普通夏玉米和高油夏玉米高氮时的表现有差异，前者全年籽粒化肥氮吸收量低于秸秆，而后者高于秸秆，表明高油夏玉米需氮量多，高氮时没有发生氮素冗余，而普通夏玉米却发生了氮素冗余，致使吸收的氮更多地残留在秸秆中。

If the outlet for straw exceed too much the star shaped discharge wheel it isadvantageous to the outlet of straw.

对放铺过程中禾秆的运动进行分析，指出了禾秆被抛出时，各种因素对它的影响。

The function of hot water pretreatment, xylanase pretreatment and hot water-xylanase pretreatment prior to soda treatment during chemi-mechanical pulping of wheat straw along with xylanase pretreatment prior to hydrogen peroxide bleaching of wheat straw xylanase soda chemi-mechanical pulp were investigated in this thesis.

本文利用热水预处理、木聚糖酶预处理和热水-木聚糖酶预处理的方法，对麦草烧碱法化学机械制浆过程中，热水和木聚糖酶预处理的作用效果以及麦草木聚糖酶-烧碱法化学机械浆木聚糖酶预处理H_2O_2漂白进行了研究。

Silver grass is weakly acidic, pH value is between 5.53 and 6.49, alkali buffer capacity is between 0.89ml and 3.31ml and acid buffer capacity is between 11.52ml and 17.38ml; To the wet ability of silver grass, the under-parts of stem are better than upsides, the inner surface of stem is better than surface, the wet ability of leaf is between surface and inner surface; compare with wood and wheat straw, the wet ability of silver grass is worse than that of wood but better than that of wheat straw.

荻草的化学成分主要是由纤维素、半纤维素、和木质素以及抽提物组成，在不同部位，各个化学成分的含量也不相同；荻草呈弱酸性，pH值在5.53～6.49之间，荻草的碱缓冲容量在0.89ml～3.31ml之间，酸缓冲容量在11.52ml～17.38ml之间；荻草茎秆下部的润湿性好于上部，荻草茎秆内表面的润湿性要好于外表面，荻草叶子的润湿性介于内外表面之间，与木材相比，荻草的润湿性不如木材，但要好于麦草；荻草茎秆下部的纵向抗拉强度要高于其上部，热处理15分钟后，茎秆下部的强度有所下降，茎秆上部有所提高，并没有表现出水热处理后荻草单元强度突然骤降的结果

The price rises frome 150 ~ 200 yuan/ton since early 2006 to the current 300 ~ 350 yuan/ton, and together with the straw management and self-consumption, the fuel prices of straw into the furnace will be higher.

秸秆直燃发电项目的燃料成本很高，发电成本很高，而电厂的上网电价却没有相应地增加，秸秆直燃发电项目的经济性较差。

The results showed that with the immersion time of straw and straw leaching solution concentration increased, the germination rate of wheat seed decreases, the time of emergence of wheat seed also will extend the POD activity of wheat seedlings, SOD activity and root activity show a downward trend , leaf MDA content was increased.

结果表明，随着秸秆浸泡时间的延长和秸秆浸出液浓度的增加，小麦种子的萌发率随之降低，小麦种子的出苗时间也随之延长，小麦幼苗POD活性增加，SOD活性和根系活力呈现下降趋势，叶片MDA含量却升高。
