Description
Technical Field
The invention relates to a comprehensive green prevention and control method for rice field diseases and insect pests, and belongs to the technical field of agricultural disease and insect pest prevention and control.
Background
Rice is an annual aquatic herb of the family poaceae. The stalks are upright, the height is 0.5 to 1.5 meters, and the stalks are different according to varieties. Rice is an important grain widely grown in tropical asia. The seeds of the rice are the rice, and the rice is called rice, scented rice, rice or rice after the rice is hulled. Approximately half of the world population all eat rice; the dependence degree of China is higher, and more than 65% of people take rice as staple food. Besides being edible, the rice can also be used as industrial raw materials for brewing wine and making sugar, and the rice husks and rice straws can be used as feed. The main rice production areas in China mainly include northeast regions, Yangtze river watersheds and Zhujiang river watersheds, belong to the most important grain crops, and the abundance and shortage of the rice directly relate to the grain safety in China.
The pest and disease damage of the rice field is one of important factors influencing the rice production, the chemical pesticide prevention and control is the main prevention and control measure at present, the chemical prevention and control is to make a prevention and control scheme according to the pest and disease damage occurrence condition, and the plant protection machinery is used for applying pesticide at the early stage of pest and disease damage occurrence to finally achieve the purpose of controlling the pest and disease damage of the rice field.
Chemical control needs to use a large amount of organic chemical pesticide, and the chemical pesticide entering the environment can directly cause pollution to water and soil, especially more serious pollution caused by pesticide packaging waste; in addition, pesticide residues are caused, the quality of agricultural products is influenced, and finally, adverse effects are generated on consumers; a large number of organic chemical pesticides can kill natural enemies of insects and beneficial microorganisms at the same time, the natural enemies of insects play a role in controlling the increase of the population number of pests through the parasitism or the feeding function, the beneficial microorganisms inhibit the reproduction of original bacteria through the antagonism and the like, and when the chemical pesticides are used for killing pests such as diseases and insects, a large number of natural enemies of insects and beneficial microorganisms can be killed, so that the pests lose the control of the natural enemies, and the pests are caused to re-raging. The long-term or unscientific use of chemical pesticides can also cause the pest and disease damage to generate drug resistance, increase the prevention and control difficulty, increase the use amount of pesticides and cause vicious circle.
At present, although some green prevention and control methods are provided for rice fields, most of the methods are developed aiming at a certain disease and insect pest, but the generation types of the disease and insect pest of the rice fields are more, the generation time span is large, and the generation levels are different, so that the prevention and the control of the disease and insect pest of the rice fields are required to be a comprehensive and systemic work, and the prevention and the control requirements are difficult to achieve by a single method or a one-sided method.
