贵南气象条件对有机青稞的影响评价

Impact Assessment of Meteorological Conditions on Organic Barley in Guinan

通过在青海省贵南县草业公司一分场、二分场、三分场3个青稞种植基地选择条件相近的地段,同一日播种,并用相同的农事技术种植同一品种有机青稞,采用农业气象方法观测气象条件对有机青稞的影响。结果表明,一分场在热量条件中优于二分场和三分场;2015年6月上旬、7月中旬—下旬和8月中旬—下旬,土壤水分对有机青稞均不利。产量,一分场地段最高,接近普通青稞本年度平均产量,经济效益远高于普通青稞,在贵南县城所在地与一分场气候条件相近的地区,可以提前播种期15 d左右,大面积推广播种有机青稞,提高经济效益。

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 in- fluence of meteorological conditions on organic barley was observed by agricuhural meteorological method. The results showed that the first subfield 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 con- ditions similar to the area can advance sowing about 15 d, large area to promote planting organic barley and improve economic efficiency.
