Technical Field

The invention relates to the field of prevention and control of tobacco diseases and insect pests, in particular to an intelligent spraying prevention and control device and an intelligent spraying prevention and control method for tobacco diseases and insect pests.

Background

Nicotiana, family Solanaceae, an annual or limited perennial herbaceous plant with a slightly lignified base. The inflorescence grows at the top, is conical and has a plurality of flowers; the capsule is egg-shaped or rectangular and round, the length of the capsule is approximately equal to the length of the preserved calyx, and the breeding and utilization of disease-resistant varieties are enhanced. According to the actual production of tobacco leaves, some disease-resistant varieties which have strong growth potential and high development speed and adapt to local environmental conditions are selected in various places to reduce the severity of diseases.

Firstly, selecting a seedbed land far away from places with a large number of virus sources, such as a vegetable land, a baking room, a tobacco shed and a warehouse, and fumigating seedbed soil and raising seedlings by using nutrition pots; secondly, during the operation of the seedbed and the field, hands and tools are practically disinfected by soap water, healthy plants are firstly treated and then diseased plants are treated in the thinning and field management, so that the users cannot smoke or eat solanaceae vegetables such as tomatoes and the like in the operation and do not need to repeatedly walk and touch the tobacco field too much. Thirdly, the cultivation management should be strengthened to improve the nutritional resistance. Applying enough base fertilizers of nitrogen, phosphorus and potassium, and spraying various trace element fertilizers in time, the disease resistance level of plants can be greatly improved. Finally, crop rotation and proper centralized planting are adhered to, and interplanting, crop rotation and crop rotation with solanaceae crops are not needed.

Aphids play a decisive role in the transmission of CMV, an important pathway of CMV viral transmission. The generation numbers of the aphids generated in one year are different from place to place, the aphids are generally bred for 15-17 generations in a parthenogenetic manner on tobacco, and the living modes of the aphids are divided into a complete period and an incomplete period, so that the overwintering hosts of the aphids are different, the aphids mainly overwinter on peach trees in an egg state, and the aphids overwinter on autumn vegetables or weeds in a wing-free female aphid state. Therefore, in the aspect of aphid control, concentrated pesticide spraying is carried out on surrounding peach gardens, vegetables, weeds and the like in 3-4 months every year, and the tobacco aphids which are hatched or recovered are killed, so that the prevention purpose is achieved.

On the basis of making other disease prevention measures, the timely application of the antiviral medicament is a good method, and antiviral medicaments can be sprayed in real time in various places according to the reality of the people, so that a better effect is certainly achieved.

Traditional tobacco plant diseases and insect pests sprinkler is carrying out tobacco plant diseases and insect pests prevention and cure in-process, all is through the distribution condition of artificial observation plant diseases and insect pests, selects the medicament, then carries out the artificial agent and mixes, and the medicament after will mixing is sprayed by a large scale through unmanned aerial vehicle, and is relatively poor to the plant diseases and insect pests prevention and cure effect in the different regions.
