天津地处华北平原东北部,主要大田作物或者农田作物是水稻、大豆、小麦、玉米以及油菜、棉花等。每种作物的病虫害都不尽相同,而病虫害的出现都将会影响作物的产量。我国很多地方都出现过因为作物病虫害严重而导致产量局减的现象,北方地区也不例外。在我国北方地区,大田作物病虫害的种类也非常繁多。在我国的农业生态体系中,所有大田作物病虫害的出现均非单独出现的,而是有一定的客观原因与主观原因,它和作物的品种、耕作制度田间群落等都有着很大的关系。接下来,基于此将对我国天津地区的大田作物中的病虫害进行分析,希望对天津地区的病虫害防治能起到一定推动作用。
Tianjin is located in the northeast of the North China Plain, the main field crops or farm crops are rice, soybeans, wheat, corn and rapeseed, cotton and so on. The pests and diseases of each crop are different, and the emergence of pests and diseases will affect the crop yield. In many parts of our country, there has been a decrease in output due to the serious crop pests and diseases. The northern region is no exception. In the northern part of our country, there are many kinds of field crop pests and diseases. In our country’s agroecosystem, all the emergence of crop diseases and pests in field crops are not alone, but have some objective and subjective reasons. They are closely related to the varieties of crops and the farmland community in farming system. Next, based on this, we will analyze the pests and diseases in the field crops in Tianjin of our country, hoping to play a certain role in promoting pest and disease control in Tianjin.
