By the Theory of Ecological Economics to Promote the Development of the Ecological Agriculture in China

Wang Songpei

1993, 1(1): 20-24.

Abstract(980) PDF(937)

Abstract:
Ecological agriculture is a new subject which is established on the background of the sustainable development in the world as well as in China.Ecological agriculture represents the combination of ecology and economy,its importance is that it points out a new direction for the agricultural modernization in China.As a new type of modern agricultural production,the ecological agriculture is built under the guide of the ecological economy theory.So it should also be developed by the same theory.In order to do so,the following concepts should be set up;the concept of ecological economic system,the concept of ecological economic balance and the concept of ecological economic results.In the same time,the ecological economic essence of agriculture should also be recognized.

The Prospect of Eco-agricultural Development in China in the Current Movement of the World Sustainable Agriculture

Sun Hongliang, Hu Tao, Zhang Renwu

Abstract(1939) PDF(1176)

Abstract:
Based on the situation of the eco-agricultural development in China,the conception and the connotation of the ecolgical agriculture,the emerging background and the process of the sustainable agriculture as well as its relationships with ecological engineering and ecological agriculture were discussed in this paper.The conception and the characteristics of the ecological agriculture in China are that the eco-agriculture is a modern agricultural system of rational ecology and good functional circles built with the combination of the achievements in modern sciences and technologies and the essence of the tranditional agriculture by the principle of ecology and systematic sciences.The authors pointed out that the ecoagriculture possesses an important role in the agricultural development in China.

Comprative studies of the Ecological Agriculture Between China and the Western countries

Shen Changjiang

1993, 1(1): 31-38.

Abstract(1128) PDF(648)

Abstract:
In this paper the difference and similarities of the ecological agriculture are compared and discussed,and the progressie level of the eco-agriculture is analysed and appraised between China and the western industrial countries.The author points out that the China's ecological agriculture is at the prior state in productive practice,but the scientific experiments and the professional education are backward.In the conclusion of the paper,the author has pointed out the ecologilization of agriculture is the inexorable trend of the all of the biological production in the whole word today.But the differences of the ecological agriculture are also existed in the developing process between china and the western industrial countries. The former one will be mainly continued along the way of system development for the productive potentials and to increase the output of products;the latter one will be mainly improved for the quality of survival environments of the mankind.But for the super quality food from the eco-agriculture is the same target for both of China and the western industrial countries.

The Obstacles in the Current Agricultural Development

Li Xianfa, Zhang Xiangqiao

1993, 1(1): 39-44.

Abstract(1178) PDF(913)

Abstract:
Several obstacles confronted in the current agricultural development are described:1)It has become more difficult than ever before to increase the per capita possession of grain yield because of the reduction in the growth-rate of grain in the world and accelerating expansion of population;2)As agricultural yields no matter in terms of economics or biology are approaching their maximum limit the current agricultural couldn't bear the anticipant load appearing in the future;3)The world grain area per capita has been reducing ceaselessly.The benefit index of agricultural input is decreasing year by year.Using chemical fertilizer and pesticide are always followed by their pollution to the environment.It is pointed out in this paper that the transforming the current agriculture is ugently necessary.

Sustainable Development of Agriculture in the North China Plain and Sorth-to-north Water Transfer

Liu Changming, You Maozheng

1993, 1(1): 45-50.

Abstract(1085) PDF(776)

Abstract:
This paper mainly deals with the ralationship between sustainable agriculture and planned water diersion from Changjiang (Yangtze) River to the North China Plain (NCP),Which is one of the most important area in agriculture in China.The NCP is located in between semihumid and semiarid zones and water resources are limited with very uneveness in time and in space.Due to rapid growth of agricultural production,a overdraft of groundwater for irrigation can be found in many irrigated districts.Consequently many cones of influence has been formed around groundwater overdraft areas where agricultural and industrial sectors increasingly use water with very high consumption.Therefore water resoruces in the NCP have been degraded year by year and can not be satisfactory for futher sustainable development of agriculture.To solve this problem,the authors consider that an important strategy is to divert water from water sufficient regions to the NCP The former wiu Provide water for the western part of the NCP on the basis of enhancing water saving agriculture in water imported areas.Thereare two planned schemes,i.e,middle route and eastern route of long distance water transfer from the Changjiang River Basin to the NCP. The former will provide water for the western part of the NCP and the latter will supply water for the eastern part of the NCP respectively.These routes are needed for whole plain and will be of great significance in supportting the NCP to build up a sustanible agriculture for the future.

A Study on the Model of Water-saving Agriculture in Water Deficit Region

Wang Xinyuan, Zhao Changsheng, Chen Hongen

1993, 1(1): 51-57.

Abstract(1064) PDF(759)

Abstract:
A model of water-saving agriculture was conducted for four years in the water-deficit and salinized area in Nanpi county.The model was generalized as follows:Setting up an agricultural water-saving planting structure;putting forward an optimized allocation scheme for agricultural water resources;setting up a complete set of water-saving engineering with the combination of deep and shallow wells and the mixed using of the salt and fresh water;perfecting a complete set of agricultural water-saving high yield techniques,centering on varieties、fertilizers、cultivation、tillage and chemical substance application. Through the last four year practice,remarkable economic social and ecological benefits have been achieved in this type of region.This not only has an impotant practical value but also has broad prospects for spreading and application.

Macroscopic Features of Nitrogen Transformation and Cycling in the Agroecosystem in China and It's Implications to Ecological Agriculture

Han chunru, Xie zongfang

1993, 1(1): 58-68.

Abstract(1006) PDF(751)

Abstract:
Quantitate diagram models are developed which illustrate the macroscopic features with its temporal changes of N transformation and circulation in Chinese agroecosystem,by using a simplified model of N cycling with 3 untrient pools of crop, livestock and soil.The results indicated an increasingly intensified tendency that Chinese agriculture is becoming more inorganic and less efficient.While the total crop biomass N product,the food N supply and the proportion of animal N in total food N were increased 2.3, 2 and 4 times more respectively in Chinese crop-livestock system by the end of nineteen eighties than at the beginning of ninetenn fifties,the total production N input and N fertilizerconsumption were increased in 8 and 187 times,with simultaneous lowering in the proportion of organic to total production N input from 97% to 25%,and decreasing the production efficiency of total and inorganic N input in terms of producing main product N from 1.12 and 3.63 to 0.34 and 0.46 respectively.The supply of forage N would have to be doubled to tripled and fertilizer N consumption more than doubled in order to meet the food N demand of an improved quality for the population grown to 1.3-1.5 billions,this would brings out serious environmental consequences.Possible options of ecological agriculture strategy are also discussed in its potentials of dealing with challenges in respect to the N transformation and circulation in Chinese agroecosystem.

Effects of Applying Molybdenum to Soybean and Intercropped Maize on the Increase of Nitiogen and Yield

Zhou Wei, Li Jiyun

1993, 1(1): 77-82.

Abstract(1222) PDF(822)

Abstract:
Molybdenum is an essential element consisting of nitrogenase enzyme complex. In our country there are many kinds of soil in which the content of available molybdenum is very low and som field trails have shown applying Mo fertilizer to be able to increase the yields of legume crops obviously. It has been indicated from some research results recently that the nitrogen fixed by legume crops can be absorbed by the intercroppedg crops,such as maize,sorghum etc. study on application of molybdenum to the intercropping system of soybean and maize has been reported in this paper,which demonstrated that applying Mo not only increased the nitrogen fixed and the yield of soybean,but also the content of nitrogen and the yield of maize in the intercropping system.For this reason, it has a great significance in crop yield increase to popularize this measure.
