安阳县位于豫北地区,在该县安阳河、漳河沿岸有大面积的砂土地,土壤润泽,排水方便,非常适合铁棍山药生长。在砂土地栽培铁棍山药是一种理想的栽培方式。但是,砂土地的保水保肥性差,需要大量的有机无机肥,如何做到合理的肥水供应,以促进铁棍山药的高产高效呢?近年来,农技部门在砂土地铁棍山药栽培中安排了大量的试验,开展了铁棍山药水肥一体化灌溉和施肥制度研究,探索和总结了 Anyang County is located in the northern area of ​​Henan Province. There are a large area of ​​sandy land along the Anyang River and Zhang River in the county. The soil is moist and drainage is convenient. It is very suitable for the growth of iron stick yam. Cultivating iron sticks in sand is an ideal cultivation method. However, the water retention and fertility of sandy soil is poor, requiring a large amount of organic and inorganic fertilizers, how to achieve a reasonable fertilizer and water supply to promote high yield and efficiency of iron bars yam? In recent years, agricultural technology sector in the cultivation of sand iron sticks Yam arrangements A large number of experiments were carried out to study the integrated irrigation and fertilization system of iron and potted yam fertilizer and fertilizer and to explore and summarize
