小麦

China has a vast territory, wheat cultivation in the region covered with different eco-climatic zones, wheat production is faced with a variety of disaster risk, including the occurrence of the prevention and control of wheat scab is an important high-quality high-yield component.

我国幅员辽阔，小麦种植区域覆盖着不同生态气候区，小麦生产面临着多种灾害风险，其中小麦赤霉病的发生防控是优质高产的重要组成部分。

Breeding wheat cultivars with low deoxynivalenol content is an effective approach to control the toxin contamination in wheat grains caused by wheat scab. In this paper, two methods for the determination of DON content in wheat grains, DON test-HPLC and GC-MS, were compared.

为选育赤霉病毒素含量低的小麦品种，减轻赤霉病危害，在比较了免疫亲和柱液相色谱法(DON test-HPLC)和气质联用法测定小麦中毒素含量的特点的基础上，利用两种方法对自然发病和赤霉病菌人工接种的小麦籽粒DON含量进行测定。

There are two filamentous wheat mosaic viruses transimitted by the plasmodiophoraceous fungus Polymyxa graminis :one is wheat spindle streak mosaic virusfirst reported in Canada and the other is wheat yellow mosaic virus first reported in Japan .

由禾谷多粘菌传播的线状小麦花叶病毒有两种，一种是加拿大首先报道的小麦梭条斑花叶病毒，另一种是日本报道的小麦黄花叶病毒。

And 50 μmol/L CdCl2 were introduced to the culture solution from the three-leaf stage with treatment duration of 24 days, and no CdCl2 in the culture solution was set as the control.

为了明确镉胁迫对小麦幼苗生理生化指标的影响，选用川35050和山农483两个小麦品种，在水培条件下设置0、30、50 μmol/L 3个处理浓度，研究Cd胁迫下小麦幼苗膜脂过氧化作用、糖氮含量和Cd吸收转运的变化。

Paste properties of starch of Nanyang color wheat under different concentrations of sodium carbonate, alum, salt or glucose were measured by Brabender viacometer. The viscosity property of starch paste and its influencing factors were discussed.

为了解食品添加剂对南阳彩色小麦淀粉糊特性的影响，采用Brabender黏度仪，测定南阳彩色小麦淀粉在添加不同碱面、明矾、食盐和葡萄糖后的黏度曲线，研究了这些因素对小麦淀粉糊化特性的影响。

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。

The authors determined glutenin protein,soluble in acid glutenin protein, surplus protein content in 21 species of wheat and indexes of rheological characteristics and made sedimentation and bread baking test. By using stepwise regression and path analysis methods,it was further proved that prediction of bread baking quality of wheat by Surplus protein content is more precise than that by sedimentaion and approximately equal to that by the score of flour. So the authors suggest that the direct selection of ...

本试验测定了21个小麦品种的几种蛋白含量以及流变学特性指标，作了沉淀试验和面包烘烤试验，借助于逐步回归分析和通径分析方法，进一步验证了用剩余蛋白含量预测小麦烘烤品质与评价值相当，比沉淀值准确的结论，并建议在小麦品质育种及面包烘烤品质分析中，加强对剩余蛋白含量的直接选择。

Inwheat intercropped with soybean not only N situation could be improved butalso P situation could be.2In intercropping,the pH of soybean rhizospherewas decreased by increasing the R-Apase activity,which could decelerate thetransforming and fixing P fertilizer.3In both monoculture and intercroppingsystem,the soil pH of rhizosphere was affected by cropping system at two Plevel which only 0.1-4mm distance from the root surface,but the effect of S-Apase activity in the rhizospher soil by cropping system was less than3mm.In effect,the rhizosphere P was really available nutrient,and applyingP to rhizosphere was effective ways to reduce the P nutrient competition.4Inwheat/soybean intercropping,the peak stage of reduction ability of roots wasthe same as that of the root growth,so that the time compensation appearedin intensity of nutrient absorption.

间套作大豆、小麦、玉米根系Apase的差异又反映出大豆利用土壤磷的潜在能力最大，而玉米最小，可见禾谷类的小麦与大豆间套后不但能改善小麦的氮素营养状况还使磷素营养也得以好转。2）间套大豆根际pH值的下降，导致磷肥施入土壤后形成〓-P的比例显著提高，转化成〓-P等难溶性磷减少，说明间套的大豆能减缓肥料磷在土壤中的转化和固定，减少磷素向无效化方向转化。3）复合群体根际土壤pH值的影响一般只发生在0.1-4mm的根际微区，而土壤磷酸酶的影响供磷与否在距根表3mm以外都无多大差异，说明根际磷才是真正有效磷，根际施磷是解决磷素竞争的有效途径。4）。

What happens to wheat farmers and the market for wheat when university agronomists discover a new wheat hybrid that is more productive than existing varieties?

当大学里的农学家们发现了一个比现有品种更高产的新小麦杂交品种时，小麦种植者和小麦市场上会发生什么？

No difference was found on the effects of nitrogen top dressing time on the processing quality between different varieties.

追氮时期对不同粒色类型小麦的形成时间和稳定时间的影响较小，但它会影响黑粒小麦的沉降值和湿面筋含量，所以氮肥运筹对黑粒小麦加工品质的改善有一定意义。
