Description

Rice planthopper catcher

Technical Field

The invention belongs to the field of instruments for rice planthopper prevention, measurement and prediction and pesticide effect test, and particularly relates to a rice planthopper catcher.

Background

Problems and deficiencies existing in history background, current situation and objectivity

The rice planthopper clusters on the stem of the lower part of the rice cluster 2 cm above the water surface to prick and suck the juice, so that the rice planthopper is harmful to rice, jumps to the water surface or escapes in case of disturbance, and is an important pest in rice production. Generally, the rice loss can be 10% -20%, and can reach 40% -60% in serious cases, even the rice is not harvested. The rice planthoppers occur in various provinces and autonomous regions in China, and in order to provide basis and means for prevention and control decisions of the rice planthoppers and ensure the grain yield, the investigation and monitoring of insect situations, the test of prevention and control medicaments and other work can be enhanced by various agricultural and technical departments in the rice planthopper occurrence period every year. The general method is as follows: the provinces of the single-season rice district are investigated once every 7, 8 and 9 months, 5, 10, 15, 20, 25 and 30 days of each month until the rice is mature and harvested 2 to 3 days, 3 types of fields are selected each time, 20 to 50 clusters or more than 50 clusters (light-emitting field blocks) are searched for each field, so that the investigation amount born by each agricultural technician is at least 3240 plus 8100 clusters or even more than 8100 clusters according to the rice planthopper investigation regulation issued by the country, the investigation amount of the provinces of the double-season rice and the three-season rice district is multiplied, 35000 rural technical departments are arranged all over the country every year, the same heavy work is repeated by the rural technical departments of the rest counties and cities, and the research and development departments of manufacturers are added, and a large amount of manpower and material resources are consumed by 3100 at all levels of the country.

However, such an important, heavy and indispensable investigation work is relatively backward and cumbersome. Because the rice planthopper catcher is lacked, pure manual operation is mostly adopted, investigators generally adopt a white enamel disc of 33cm by 45cm as a carrier, and the inner wall of the disc is wetted by water to play a role in adhering the rice planthopper; the harmful part of the rice planthopper is arranged on the stem at the lower part of the rice cluster 2 cm above the water surface, so that when the rice planthopper is caught, an agricultural technician needs to bend down to get down the waist, insert the disc into the rice row with one hand, tightly press the lower edge of the disc against the base part of the rice cluster on the water surface, press the rice cluster with the other hand to be attached to the disc surface, and quickly slap the middle lower part of the rice cluster with a palm to frighten the rice planthopper and fall into the disc, thereby achieving the purpose of catching.

However, such a conventional capturing method has serious disadvantages. Firstly, the operation is complicated and the links are more. And secondly, the rice planthopper has higher trapping rate. As the rice planthoppers surround the rice clusters for 360 degrees, the catching operation is single-side slapping, single-side insect receiving, bending over by agricultural technicians, and adopting the white enamel disc to be tightly attached to the base parts of the rice clusters, the phenomenon that the rice planthoppers are disturbed in the early stage to cause part of catching leakage is avoided. Again, it is labor intensive. In the investigation period, the agriculturist need to repeatedly bend over at least 3240-. Therefore, the rice planthopper catcher which is simple to operate, high in catching efficiency and capable of effectively reducing labor intensity is urgently needed by agricultural technicians.
