山西省是水资源严重匮乏的省份之一,旱地面积占到该省总耕地面积的79%。有很多地方依然是在靠天吃饭。由于降雨量少,且范围分布不均匀,再加上降水利用率低等原因,造成了本省农业产量低而不稳。膜下滴灌作为一种高效的节水灌溉技术,现阶段,被大量应用于大棚种植中。河村基地是旱作农业示范基地,由于当地干旱,且地下水缺乏,多年来,基地一直致力于节水灌溉的推广。将滴灌技术引入大田灌溉,实施关键期补水,可有效地保证农作物的生长需水。
Shanxi Province is one of the provinces with serious water scarcity. The dry land area accounts for 79% of the total cultivated land area in the province. There are still many places to eat by the sky. Owing to the small amount of rainfall and the uneven distribution of the area, coupled with the low utilization rate of precipitation, the agricultural output in the province was low and unstable. Drip irrigation film as an efficient water-saving irrigation technology, at this stage, is widely used in greenhouse cultivation. Kawamura base is a demonstration base for dry farming, due to the local drought, and the lack of groundwater, over the years, the base has been committed to the promotion of water-saving irrigation. Drip irrigation technology will be introduced into the field, the implementation of the key period of replenishment, which can effectively ensure the crop water needs.
