Basial nitrogen fertilizer of traditional treatment can beget leaching loss of soil nitrate before top-dressing, but top-dressing beget hardly the leaching loss because cotton assimilated large numbers of nitrogen for accelerated growing.

传统处理施肥量高，基肥比例大易引起土壤硝态氮的淋移损失，损失数量与棉花生育时期有关，棉花生育期追氮由于棉花对氮素的大量吸收，硝态氮淋移损失相对较小。

The results of HPLC tests indicated that Bt toxin in Bt transgenic cotton had not obviously affected the contents of flavonoids (mainly rutin and isoquercitrin and a few quercetin ),contradictively ,the result of combined dosage test in vitro showed that that rutin had significantly enhanced the suppression of Bt-ICP on the cotton bollworm larvae., in addition to the

采用高效液相色谱法测定转Bt基因棉花主要抗虫黄酮类化合物的的变化，结果表明外源Bt杀虫蛋白表达不会对棉花自身原有的主要抗虫黄酮类物质（包括芸香苷、异槲皮苷和含量较少的槲皮素）产生不利的影响，因此可以将Bt杀虫蛋白基因转入抗虫黄酮类物质中国农业科学院博士学位论文含量高的棉花品系。

In this study, an attempt is made to account for the observed difference in the susceptibility of Gossypium hirsutum L.(cv. BD-18 and Simian 3, resistant and susceptible to V. dahliae, respectively) to toxin of Verticillium dahliae, by looking for differences in the timing and level of production of NO and H_2O_2, and their effects on the expression of GST gene.

本实验以棉花抗病品种BD-18和感病品种泗棉三号的悬浮细胞为材料，研究了棉花细胞在黄萎病菌毒素处理后H_2O_2和NO的变化，并用半定量RT-PCR的方法检测毒素、H_2O_2和NO对棉花谷胱苷肽-S-转移酶基因转录水平的影响。

The reflection that price of our country cotton reforms Wang Qing result, price of cotton of Liu supernatural power is one of main factors that affect pily production.

我国棉花价格改革的思考王庆功，刘法力棉花价格是影响棉花生产的重要因素之一。

The author suggests concerned division system is decided and announce our country the schedule that 35 years in future indrawn international market releases pily excessive stock, be opposite with eliminating pily inventory to release uncertainty to reach its to the greastest extent international market pressure, thereby loss of better implementation cotton is the smallest change an end.

作者建议有关部门制定并公布我国在未来三五年内向国际市场释放棉花过量库存的时间表，以最大程度地消除棉花库存释放不确定性及其对国际市场压力，从而较好实现棉花亏损最小化目标。

Sericultural for actin fibers, fine silk and the tenacity of porous, high thermal performance, are cotton, 1.2 times the hygroscopicity of cotton are 1.5 times the elastic flexibilityìcompressed cotton are 3 times 2 times the wool to prevent cold bones moisture penetration, and exchange of steam.

蚕丝为动蛋白纤维，丝细多孔而坚韧、保暖性能极高，是棉花的1.2倍，吸湿性是棉花的1.5倍，压缩伸拉弹性弹性是棉花的3倍，羊毛的2倍，可防止寒湿气透入筋骨，并交换蒸汽。

The open reading frame of Spinacia oleracea Betaine Aldehyde Dehydrogenase was retrieved from Spinacia oleracea and inserted into the Agrobacterium tumefaciens binary vector pBin438, which was driven by CaMV35S promoter, and produced the new binary vector pBSB. A. tumefaciens LBA4404 carrying this plasmid was used in genetic transformation of plants. Forty-five primary transgenic plants were detected by PCR and verified by the Southern blotting from 65 regenerated plants, of which 27 transgenic plants had only one copy of T-DNA.

摘 要：分离出菠菜甜菜碱醛脱氢酶基因构建成由CaMV35S驱动的双元植物表达载体pBSB，农杆菌菌株LBA4404携带该载体转化棉花，获得转基因棉花植株。65株转基因植株经过PCR筛选、Southern blotting分析证明有45株为成功的转化株，外源基因已经被整合到棉花的染色体组中，并以单拷贝插入居多。

The effects of six inorganic compounds, K2CO3, KOH, KCl, NaCl, MgCl2 and ZnCl2 were investigated on pyrolysis of cotton stalk by thermal analysis. The results showed that devolatilization occurred at lower temperature as the cotton stalk was treated by K2CO3 or KOH, whereas cotton stalk samples treated with KCl, NaCl, MgCl2 or ZnCl2 devolatilized at higher temperature compare with the untreated biomass.

通过热重分析实验观察K2CO3、KOH、KCl、NaCl、MgCl2和ZnCl2 6种无机催化剂对棉花秸秆热解催化效果的影响。K2CO3、KOH处理过的棉花秆与纯棉花秆相比热解发生在较低的温度范围，而KCl、NaCl、MgCl2和ZnCl2处理过的棉花秆热解发生在较高的温度范围。

Show that the 1 lateral 4 rows and 2 laterals 4 rows to increase the volume of nitrogen fertilizer and irrigation will help improve cotton yiled, with 2 laterals 6 rows increased irrigation and fertilizer control in favor of increasing cotton yiled.

综合分析，AFI最能有效降低棉花根区硝态氮损失，使硝态氮和铵态氮含量主要分布在棉花根系有效吸收范围内，有利于棉花氮素吸收和利用。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
