  wheat productivity
Exploitation of the benefits derived from large initial seed size may be a cost-effective management strategy for improving wheat productivity in salt-affected areas.
      
The results show that an increase in C sequestration will result in enhanced wheat productivity but the increase will depend on the amount of fertilizer applied and the existing fertility level of the soil.
      
The change in wheat productivity with SOC concentration shows that the effect of additional C sequestration on wheat productivity will depend on the existing SOC concentration, being higher in low SOC soils.
      
The wheat productivity per ton of organic carbon declined curvilinearly as the native SOC concentration increased.
      
The contribution of 1?ton SOC ha-1 to wheat productivity ranged from 15 to 33?kg?ha-1 across SOC concentration ranging from 3 to 9?g?kg-1 soil.

It is a common practice in the middle part of Shanxi province that wheat is sown as soon as the previous crop is harvested in the late autumn. The result in this study shown that blindly enlarged seeding rate is one of the major factors affecting the yield and yielding stability.New methods of enhancing the local wheat productivity was suggested.

对起巷小麦产量不稳的状况进行了试验研究。结果表明,盲目加大播量是造成赶茬小麦产量不稳的重要因素之一,迟中争早,早稀晚密,适当加大播量是夺取小麦高产稳产的关键。增磷稳氮,促控结合是赶茬小麦夺取高产的保证。该项技术在保证小麦高产稳产的基础上,可为夏播作物延长5~10天的生育期,使山西中部平川一年二作成为现实。

Productivity of crops is mainly decided by the seed production of annual cereals in arid and semi arid areas.Lower and unstable production of crop yield is constrained by pest and other stressing environments,in which limited water in the area is a main factor limited crop production.There are probably two ways to improve crop yield in the areas:one is to improve the environment where crop plant survive and grow,another way is to breed suitable genotypes,which are adaptable to the environment.The discovery...

Productivity of crops is mainly decided by the seed production of annual cereals in arid and semi arid areas.Lower and unstable production of crop yield is constrained by pest and other stressing environments,in which limited water in the area is a main factor limited crop production.There are probably two ways to improve crop yield in the areas:one is to improve the environment where crop plant survive and grow,another way is to breed suitable genotypes,which are adaptable to the environment.The discovery of dwarfing genotype in favorable areas has made wheat productivity increased significantly throught the increase of harvest index.However,in arid and semi arid areas,breeding of crops has not attained such an efficient progress.It is believed that with further understanding on the relationships between evolution,drought tolerance and seed yield of crop plants,an efficient breeding way will be discovered in the areas.

粮食问题主要取决于一年生谷类作物产量。作物产量低而不稳的原因主要是病虫害及各种胁迫生境 ,其中干旱缺水为最大的产量限制因素。提高作物生产力的途径有二 :其一是改善作物的生长环境 ,其二是通过育种手段选育在各种胁迫环境中具有优良表现的基因型(品种 )。矮秆化育种手段使水肥充裕区小麦产量有显著的提高 ,是通过提高收获指数获得的。干旱、半干旱地区育种却未能获得显著效果 ,要提高干旱、半干旱地区小麦育种的成效 ,对干旱、半干旱地区植物的适应进化、抗旱性及产量关系问题的认识尚有待进一步地提高
