Description

A drug sustained-release device for preventing tobacco virus and its application method

technical field

The invention relates to plant disease and insect pest control technology, in particular to a drug slow-release device for preventing tobacco virus and a use method.

Background technique

Tobacco is a crop that loves temperature and humidity, and is sensitive to temperature. Different temperature conditions have a greater impact on the quality and yield of tobacco. Moisture is very important to tobacco. First, tobacco plants are tall, with broad leaves and large leaf area coefficients. Strong transpiration requires more water supply; the second is that water affects the effectiveness of fertilizers; the third is that water affects the extension of leaves; when water supply is sufficient, the cell turgor of tobacco leaves is larger and can be fully stretched, and the leaves of tobacco leaves can be lengthened , widening, and loose structure; fourth, water affects the physiological metabolism direction in the tobacco plant; when the water supply is sufficient, it can promote carbon metabolism in the tobacco plant, and the sugar in the tobacco leaves accumulates more; fifth, water affects the maturity characteristics of the tobacco leaves, thereby affecting quality of tobacco leaves.

The humidity-loving growth environment provides a good environment for the growth of tobacco virus diseases in the process of cultivation and planting. At present, the discovery of tobacco viruses is not timely, delaying the treatment of tobacco viruses, leading to large-scale tobacco infections, reducing tobacco production, reducing tobacco quality, and causing loss.
