砂礓黑土是河南省低产土壤,具有易旱、易涝、易渍的明显缺陷,产量低,制约了农业生产的发展。在砂浆黑土区通过灌排实验,减少水稻串灌、漫灌,探索出节水灌溉的新思路,水稻每公顷节水一半左右,达到投资少、见效快的效果。为改变砂浆黑土区农业增产,灌排结合找到一个新办法,为河南农田水利基础建设如何保丰收找到新途径。 Sandy clayey black soil is a low-yielding soil in Henan Province. It has the obvious defects of drought, waterlogging and easy to stain. Its yield is low, which restricts the development of agricultural production. In the black soil area through irrigation and drainage experiments, to reduce the rice string irrigation, flood irrigation, to explore a new idea of ​​water-saving irrigation, saving about half of water per hectare of rice, to achieve less investment, quick results. To change the agricultural production of black soil mortar, irrigation and drainage to find a new combination of methods for Henan farmland water conservancy infrastructure to find new ways to save a good harvest.
