摘要 通過在青海省貴南縣草業公司一分場、二分場、三分場3個青稞種植基地選擇條件相近的地段,同一日播種,并用相同的農事技術種植同一品種有機青稞,采用農業氣象方法觀測氣象條件對有機青稞的影響。結果表明,一分場在熱量條件中優于二分場和三分場;2015年6月上旬、7月中旬—下旬和8月中旬—下旬,土壤水分對有機青稞均不利。產量,一分場地段最高,接近普通青稞本年度平均產量,經濟效益遠高于普通青稞,在貴南縣城所在地與一分場氣候條件相近的地區,可以提前播種期15 d左右,大面積推廣播種有機青稞,提高經濟效益。

Abstract In Guinan grassland industry company,through first sub-field, second sub-field, third sub-field three barley planting base selection conditions similar to the lot, the same day sowing, and with the same agricultural technology to grow the same species of organic barley,the influence of meteorological conditions on organic barley was observed by agricultural meteorological method.The results showed that the first sub-field was better than second sub-field and third sub-field in the heat conditions. In early June, mid July to late July,mid August to late August,soil moisture was not good for organic barley.Production, the first sub-field was the highest and close to the average annual production of ordinary barley, the economic benefits was much higher than the ordinary barley.In the county town of Guinan and third sub-field climate conditions similar to the area can advance sowing about 15 d, large area to promote planting organic barley and improve economic efficiency.

生長在青藏高原的高寒作物青稞,具有生長周期短、耐寒、抗旱和產量高等特點[1]。青海省貴南縣地區氣候適宜青稞的生長,作為特色農業,有著大面積種植傳統。但生育期內光熱水氣象要素的分配不均,易發生干旱、霜凍、高溫熱害等災害,這使農戶在種植時大量使用化肥,以肥養田來提高產量。近年來,貴南縣以創建青海省首家國家有機產品認證示范縣為契機,大力推進生態保護-種草養畜-農畜產品加工-有機肥還田的農牧業循環經濟,借助青海互助青稞酒股份有限公司在貴南縣建立有機青稞酒原料大基地的有利時機,在貴南草業公司積極建立了沒有任何污染的6 160 hm2有機青稞種植基地,發展有機青稞的種植產業。……
