| 摘 要： | 结合气象资料,根据气候变化的结果与变化趋势,筛选出适合中部干旱带种植的优质抗旱苜蓿品种,探索在干旱条件下整地、保苗等栽培技术措施,确定技术简单、成本低的抗旱保苗技术。认为:旱作条件下(高温干旱),混播荞麦比地膜覆盖、裸地种植的出苗率高,是保苗简单易行的方法。

| Abstract: | Some high quality and drought-resistant alfalfa varieties suitable to grow in the Middle Arid Zone of Ningxia were screened based on the result of climate change and change trend and combining the meteorological data.An exploration was made on the cultivation technologies such as soil preparation and keeping a full stand of seedlings.An drought-resistant and keeping a full stand of seedlings technology characterized by simplicity and low cost was determined.It is of the opinion that under condition of dry farming(high temperature and drought) the rate of emergence when it was interplanted with buckwheat was higher than that of plastic film mulching and bare land planting and is a simple and easy method for keeping a full stand of seedlings |
