With advantageous water , soil and organisms resources , the dadiwan culture , the yangshao culture , the longshan culture and the xiashang culture developed , original settling - down dry farming culture formed gradually , which laid sound foundation for agriculture civilization in the weihe valley ; among which , land use of arable farming was replaced largely by pastoral farming in the mixed area of agriculture and animal husbandry in north weihe region between 4 000 - 3 000 a b . p . , because of dry and cold weather resulted in environment deterioration and soil degradation . at the beginning of 3 100 a b . p . , 在8500 3100abp全新世大暖期,渭河流域水、土、生物資源條件優越,人類發展了大地灣文化、仰韶文化、龍山文化和夏商文化,逐步形成了原始定居旱作農業類型文化,從而奠定了渭河流域農業文明的基礎,其間在4000刁000ab衛,渭河流域北部的農牧交錯帶,由于氣候的逐漸冷干化,導致水、土、生物資源退化,造成旱作農業土地利用方式由游牧業取而代之。

On the basis of the discussion of the ecological rehabilitation on subsidence land of coal extraction , the land structures of nourishment , plane and perpendicularity on subsidence area of coal extraction are differently designed . on nutritive structure green crops are mainly common crops , green vegetables , green forage crops and acquatic creatures . on plane structure the center of the subsidence land of coal extraction can be used as fish culture in net cage , the periphery can be established as fish pool and economic crops in water , and the outmost layer can be used as high - yield field , vegetable shed , domestic animal breeding area and fruit - bearing forest . on vertical structure the deepwater area can be established as fish pool and economic crops in water , and the uppermost layer can be developed as acquatic and semi - acquatic crops or dry farming crops 在討論采煤塌陷地生態復墾的基礎上,對新泰市采煤塌陷區生態復墾用地的營養結構、平面結構和垂直結構進行了優化設計.在營養結構上,綠色作物主要是農作物、蔬菜、飼料及水生生物.在平面結構上,在塌陷的中心地帶實施網箱養魚,外圍區建立精養漁塘和水生經濟作物,最外層生態復墾為高產農田、蔬菜大棚、畜禽養殖區和林果地.在垂直結構上,在積水區建立精養漁塘和水生經濟作物,最上層則發展水生、半水生及旱作綠色經濟作物

In dry farming in the northern great plains , mary hargreaves reviews the changes in agricultural technology and farm management through the 1920s , the introduction of federal programs as drought and depression recurred in the 1930s , and the realignment of concerns from drought to marketing instability during the recovery years that followed 描述:在《北部大平原的旱作農業》這本書里,作者回顧了20年代在該地區旱作農業的技術和管理, 30年代政府對旱作農業所創立的一些工程以及后來對旱作農業的調整。

Then , main projects and synthetic techniques of ecological agriculture construction are discussed . the results indicate that main projects include fertile soil project , water conservancy , forestation and virescence project , agricultural structure adjustment project , agriculture industrialization project , integrated use of agriculture rejectamenta project , high quality and innoxious farm produce project , livestock breeding project , sight - seeing agriculture project , etc . the suited techniques include ecology location scheme technique , agriculture rejectamenta use technique , energy source regeneration technique , sewage biologic depuration technique , innoxious farm produce technique , soil fertility increase technique , ecological control technique of plant disease and insect pests , economizing water technique of dry farming , agriculture environment reconstruction technique , etc . lastly the study brings forward the countermeasure and advice of ecological agriculture development 根據我國生態農業建設成功經驗和濟南市目前生態農業建設基礎,提出濟南市生態農業建設重點工程為沃土工程、農田水利工程、造林綠化工程、農業結構調整工程、農業產業化工程、農業廢棄物綜合利用工程、優質和無公害農產品工程、養殖工程、觀光農業工程等;生態農業建設的關鍵技術為生態位配置技術、農業廢棄物資源化綠色技術、能源再生技術、污水生物凈化利用技術、無公害農產品技術、地力持續培肥利用技術、農作物病蟲草害生態控制技術、旱作農業高效節水技術及農業生態環境綜合整治技術等。

Then it analyses the different function of irrigation projects as glebe , paddy field , farmland in the xia , shang and western zhou dynasties , further proves the irrigation works of southern paddy field area is earlier than north drying farming area , so the north irrigation project technology is from southern china 又分析夏、商、西周三代時旱田、水田溝洫水利工程的不同作用,進一步證明南方水田地區灌溉水利早于北方旱作地區,灌溉水利工程技術應是從南方傳入北方的。

It is true that a high proportion of the newly farmed land was suitable only for grazing and dry farming , but agricultural practices had become sufficiently advanced to make it possible to increase the profitability of farming by utilizing even these relatively barren lands 確實讓步口氣,很大一部分新開墾的土地只能夠用于放牧和旱作,但是語氣上轉回來,農業手段已經非常進步,完全可以增加農業的收入,即使利用這些相對貧瘠的土地。
