平原易碱地区发展灌溉,必須适应这些地区在气候、地形、水文地质和土壤等自然因素和农业生产技术水平方面的特点,违背了这些規律,灌溉就会得到相反的結果,不但不增产,还要把地浇坏,使土壤发生盐碱化。正如有些灌区群众所說的:“一年增产,二年平产,三年减产”。灌溉肯定是主要增产措施之一,問題在于在平原易碱地区怎样灌溉,土壤才不碱化。灌区群众反映,“不灌又旱,灌又怕碱”,說明灌而不碱是生产中迫切需要解决的問題。灌而不碱实质上也就是盐碱地的合理灌溉問题。而合理灌溉 The development of irrigation in the plains of the Alkaline region must be adapted to the characteristics of the natural factors such as climate, topography, hydrogeology and soils and the technical level of agricultural production in these areas. Contrary to these rules, irrigation will have the opposite result, not only increasing production but also To be badly poured, the soil salinization occurs. As some of the people in the irrigated areas said: “One year increase in production, two years of production, three years of production cuts.” Irrigation is certainly one of the major stimulants, and the question is how to irrigate the soils in the plain Alkali. Irrigation areas reflect the masses, “no irrigation and drought, irrigation and fear of alkali,” irrigation without alkali is an urgent need to address the issue of production. Irrigation is essentially irrigated alkaline saline irrigation issues. Reasonable irrigation
