湖北省耕地人均占有量低、中低产田比重大,应加强对冷浸潜育型、干旱灌溉型、坡地梯改型、瘠薄培肥型、渍涝排水型、障碍层次型、酸化耕地型等障碍类型的中低产田技术改良,促进粮食稳产高产,确保粮食安全。 Hubei Province has a low per capita possession of cultivated land and a large proportion of middle and low-yielding farmland. Therefore, it is necessary to intensify the study on the effects of cold soak potential type, arid irrigation type, sloping landform type, infertile fertility type, waterlogged drainage type, obstacle level type, acidified cultivated land type Obstacle types of low-yielding field technology improvements to promote stable and high yield of grain to ensure food security.
