Description

Device and application method for moth-repelling rice leaf roller in rice field

technical field

The invention relates to a moth-repelling device for farmland, in particular to a moth-repelling device for rice leaf rollers in rice fields based on GSM remote communication and the principle of planar connecting rods and an application method thereof.

Background technique

The moth-repelling method in the field is a routine method used by the plant protection departments at the grass-roots level in the actual systematic forecasting of the rice leaf roller. The survey results basically reflect the law of the growth and decline of the moth population in the field. The specific operation is that the plant protection personnel select one field each of the main cultivar types with different growth periods and good, medium, and poor growth conditions. The survey area of each field is 50 m ² ~100 m ² , and hold a bamboo pole about 2 m long along the field ridge against the wind. Slowly move the middle and upper part of the rice bushes (survey the surrounding weeds at the same time before the middle stage of rice tillering), and at the same time scan the adult moths of rice leaf rollers taking off with the naked eye, and count the number of moths silently or with a counter. When the amount of moths per pole is very large (more than 100), visual estimation can be carried out. It will be conducted before 9:00 a.m. every other day, and once a day during the peak period. When the rice seedlings are in the stage, it is enough to use a bamboo pole to gently stir the upper part of the rice seedlings. In the middle and later stages of rice, it is necessary to vigorously stir the middle and upper parts of the rice plants, so that the adult moths hidden in the rice bushes can fly up, which is convenient for counting . Although the method of catching moths is simple and easy to master, there are still many problems in actual operation: (1) The counting accuracy of manually catching moths is poor. Because the moths stay in the air for a short time, it is difficult to accurately estimate the number of flying moths by counting silently, counting counters or visually, and it is difficult to meet the requirements of modern accurate and quantitative pest forecasting. (2) The rice leaf roller is greatly affected by the subjective conditions of moth eliminators. Visual counting can easily cause eye fatigue. The strength of moving the bamboo pole will affect the number of moths taking off, and the counts of different moth catchers are very different. (3) The number of flying moths is affected by the weather. For example, wind, cloudy weather, etc. will all have a certain impact on the take-off of rice leaf rollers, and the time, location and direction of moth removal need to be considered. Inaccurate numbers of moths often lead to inaccurate estimates of their occurrence, which directly affects the correct formulation of control strategies. (4) Manual moth removal in the field consumes a lot of energy and is inefficient. At present, there is no economical and applicable automatic moth-repelling device for rice leaf rollers both at home and abroad.
