我省耕地面积2853万亩,稻田占41.9％,旱田占58.1％。粮食作物以水稻、玉米为主,经济作物主要是油菜、烤烟、麻类、茶叶和柑桔。由于地势高差大、气候垂直差异明显,南部地区以一年三熟为主,中部、东部、北部地区一年两熟,西部地区一年一熟。农田草情复杂,为害亦不平衡。为掌握我省农田杂草种类和分布情况,为综合防除杂草提供依据,我们从1982年春开始,开展了全省农田草害调查,现将调查结果总结如下: 一、调查范围与方法根据我省地势及植物水平分带性差异等因素,在黔南、黔东、黔中、黔西、黔北五大农业区域中,选定遵义、赤水、黔西、威宁、铜仁、印江、普安、安龙、册享、普定、天柱、
Our province cultivated area of 28530000 acres, 41.9% rice fields, drylands accounted for 58.1%. Food crops mainly rice, corn, cash crops are mainly rape, flue-cured tobacco, hemp, tea and citrus. Due to the large elevation difference, the vertical difference in climate is obvious. The southern part is dominated by three crops in one year. The middle part, the eastern part and the northern part are double cooked in one year and the western region is cooked in one year. Farmland grass complex, damage is not balanced. In order to grasp the types and distribution of farmland weeds in our province and provide a basis for the comprehensive prevention and control of weeds, we started the survey on farmland grassland diseases in the province from the spring of 1982. The survey results are summarized as follows: I.
