贵州东部是贵州省稻田集中分布地区,共有稻田近500万亩,占全省稻田的40％左右,是贵州水稻集中产地之一。但该区低产田面积较大,单产不高,是贵州水稻生产上的一个重要问题。为了弄清该区低产田主要类型、形成原因和分布规律,以便为改良该区低产田提供依据。 Guizhou Province, Guizhou Province, the eastern part of the concentrated distribution of rice fields, a total of nearly 5000000 acres of paddy fields, accounting for about 40% of the province’s rice fields, Guizhou is one of the concentrated areas of rice. However, the area of ​​low-yielding land in this area is relatively large and yield per unit is not high, which is an important issue in rice production in Guizhou. In order to find out the main types of low-yielding fields in this area, the causes and distribution patterns of them were analyzed in order to provide basis for improving low-yielding fields in this area.
