Multi-functional cup integrating rice field lamina color comparison and natural enemy releasing

Abstract

The invention discloses a multi-functional cup integrating rice field lamina color comparison and natural enemy releasing. The multi-functional cup comprises a color comparison cup body with the lower end open, a food groove and a connecting rod. A connecting hole and a ventilation hole are formed in the upper end face of the color comparison cup body, and a trichogramma card is attached to the inner wall of the color comparison cup body. The connecting rod penetrates through the connecting hole, the lower end of the connecting rod is connected with the food groove, and the food groove is located in the color comparison cup body. Due to the fact that colors of cup bodies different in green degree are compared with colors of rice field laminas, the fertilizer condition of a rice field can be timely judged, a farmer is instructed to appropriately perform topdressing and fertilizer controlling at appropriate time in the production process of grain, so that blind fertilizer application is avoided in the process of planting rice; meanwhile, the cup can serve as an emergence place of trichogramma before the trichogramma enters parasitic stem borer eggs of the rice field and provides a good emergence environment for the trichogramma, and the parasitic capacity, in the rice field, of the trichogramma is improved, so that the efficiency of pest control is promoted.

Description

technical field [0001] The invention belongs to the technical field of paddy field fertilization and pest control equipment, and in particular relates to a multifunctional cup integrating paddy field leaf colorimetry and natural enemy release. Background technique [0002] As a large agricultural country, China uses a large amount of chemical fertilizers in rice planting, and the average amount of fertilizer per mu is at a high level in the world. This is mainly due to a very prominent problem in China's rice fertilization technology: farmers do not understand the nutrient content of the soil The relationship between high-yield leaf color and high-yield leaf color, long-term use of a fixed fertilization pattern, the phenomenon of blind fertilization is serious, and fertilizer waste is serious; excessive fertilization causes soil acidification, secondary salinization, and the growth of harmful organisms, making it difficult to fully realize the high-yield potential of rice. ,...
