摘要
辽宁西部地区属半干旱地区,压片式微喷带灌溉技术具有抗堵塞性好、灌水均匀、价格低廉等优点,在辽西地区应用广泛。通过实验对比压片式微喷带灌溉技术、传统灌溉及雨养农业等不同灌溉方式,分析不同灌溉方式对灌水量、作物长势及产量的影响。结果表明:压片式微喷带灌溉可减少灌溉水量、降低耗水率、提高部分产量并提高水分利用效率。可为微喷带灌溉技术的进一步推广提供借鉴。
The western part of Liaoning is a semi-arid area. The tablet-type micro-spray irrigation technology has the advantages of good anti-blocking, uniform irrigation and low price, and is widely used in western Liaoning. By experimenting with different irrigation methods such as tablet-type micro-spray irrigation technology, traditional irrigation and rain-fed agriculture,the effects of different irrigation methods on irrigation amount, crop growth and yield were analyzed. The results showed that the micro-spray irrigation can reduce the amount of irrigation water. Reduce water consumption, increase part of production and improve water use efficiency. It can provide reference for the further promotion of micro-spray irrigation technology.
