摘要:貴州省地處云貴高原東側,是我國石漠化較為嚴重且經濟欠發達的農業地區,但這些地區具有適合高山反季節蔬菜種植所需的溫度、光照、水分和土壤等自然條件。黔西北、黔西南等地區近些年來的高山反季節蔬菜生產實踐表明,貴州海拔500 m以上山區適合種植蔬菜,特別是夏秋蔬菜。在貴州高山地區發展反季節蔬菜,能促進石漠化地區的農業發展和現代生態農業模式的建立,進而促進生態環境的良性發展。

Abstract: Guizhou is located at the northern Yunnan plateau,it is the agricultural area that is stony desertification badly and economic underdevelopment,but the area has the natural conditions of temperature,highlight,moisture and soil that is suitable for the mountain anti-season vegetables cultivation. The producing practice of the mountain anti-season vegetables in Northwest and Southwest Guizhou indicated that,the mountain area with an elevation of 500 m in Guizhou is suitable for planting vegetables,especially the Xia Qiu vegetables. Developing anti-season vegetables cultivation in mountain area of Guizhou could promote the agricultural development of stony desertification area and the establishment of modern ecological agriculture model,thereby promote the healthy development of ecological environment.
Key words: mountain; off-season vegetables; multi-level utilization model; modern ecological agriculture; Guizhou
蔬菜是人民生活中不可缺少的副食品,對保障城市生活、發展農村經濟均具有重要的意義。隨著市場經濟的發展和農村產業結構的調整,高山反季節蔬菜栽培應運而生,并受到普遍關注而發展起來[1]。高山反季節蔬菜,就是在海拔500 m以上的山區種植能夠滿足大中城市“伏缺”供應的蔬菜[2]。貴州省雖是全國夏秋蔬菜生產的重點區域,蔬菜是貴州農業產業中除茶葉、煙草外的第三大產業,但是在經濟欠發達的農業省區,土地石漠化面積的迅速擴展已極大地制約了本地區社會經濟的發展,不但嚴重威脅到人們的生存環境,而且還危及到貴州省及長江、珠江中下游地區的可持續發展[3]。
