Agricultural Extension System is the organization system adopted by the state government for undertaking agricultural extension work, which includes organization structure and management approaches of agricultural extenuation institutes.
This paper chiefly introduced the major achievements of Shaanxi apple industries nearly 20 years ,the major superiority and protruding problems of apple industry development were analysed,the essential target and overall tentative plan of scientific research and extension work in the next few year were put forward.
As a member of the research group, I utilized the relative results of modern ecological agriculture and ecological engineering research in our country, synthesized many projects' and disciplines' research methods, started the research, demonstration and extension work from the view of the ecological engineering technology on the hilly orchards in the south of China.
Sand producing is a serious problem in wells located in s1+2 reservoir of block Leng 43, Lengjia oilfield, and the effect of high temperature sand consolidation and TBS sand control is poor. So that artificial borehole wall sand control has been tested on site and popularized, and has increased oil production with average cyclic increment of 1 125 t and cumulative increment of 2 249 t.
Aiming at the blank of international popularized Wushu talent and the monotonous training situation of Wushu talent without hierarchies in physical education colleges, this article probes into the international popularization of cultivating pattern of Wushu talent in order to promote the international populization and development of Wushu.
Hip and ankle extension work proportionally decreased with increased work load.
These findings have important curriculum implications, for example, for those planning extension work for mathematically able students.
The use of rapid soil and plant tests in teaching, research and extension work
The data gathering methods for evaluating such extension work, involving over 6000 people, is discussed in the light of a mobile people, lack of sampling frame and large distances in an arid and semi-arid environment.
In the future, improved mobility of farmers and extension work may facilitate seed exchange over longer distances, and consequently jeopardise preservation of locally adapted landraces in barley.
According to authers' experiences of dissemination and applications of 'SAP' and 'NFAP' programs, this paper is concerned with the review of highlights in finite element applications in engineering, which have got fast progress in China in recent years. Emphasis is placed on the analysis of objective circumstances in China and the right way of dissemination work, And then, future development is suggested.
This paper proved which the non-homogeneous boundary value problem for population evolution equatiuns is well-posed in Sobolev space H~(1, 1) (Ω_T) This generalized important results of works [4—6]. It provided a strictly mathematical basis for futher research of population control problems
