Description

Technical Field

[0001] The utility model belongs to the technical field of fruit tree cultivation management tools, in particular to a special medicine smearing device for fruit trees. Background Art

[0002] As one of the pillar industries of agriculture, fruit trees have broad development prospects, and the corresponding fruit tree management technology is constantly improving. In the existing technology, the application of appropriate agents can effectively save investment costs, reduce labor input, and is conducive to the production of high-quality standardized products in a simplified, labor-saving and efficient manner. At present, there are many tree management scenarios that require the targeted application of agents to fruit trees. For example, after deciduous fruit trees enter deep dormancy, they need a certain limit of cold temperature requirements in spring to break dormancy. However, in facility cultivation, the required cold and light conditions are difficult to achieve; in order to ensure normal germination and flowering in the later period, in the production of fruit trees such as grapes, kiwis, apples, pears, peaches, apricots, plums, persimmons, raspberries and figs, most of them use chemical dormancy breaking agents (such as cyanamide), which can promote fruit trees to germinate early, improve the uniformity of germination, and have significant directional germination effects, low cost, easy to use, safe and reliable. For another example, newly planted fruit trees or partially bare adult fruit trees need directional or multiple branching for rapid shaping and early yield improvement. Some trees have a strong branching rate but unsatisfactory direction, and also need directional branching. "Branching factor" (such as synthetic cytokinin) is often used on cherry, apple, pear, kiwi and other fruit trees to promote germination, improve branching rate, and cultivate fruiting branches. It can not only achieve the requirements of rapid shaping, early shaping, early formation, and early high yield of fruit trees, but also has the characteristics of significant directional branching effect, low cost, convenient use, safety and reliability. For another example, the wound of a fruit tree caused by grafting or head replacement is slow to heal by itself. Some use plastic cloth or soil to seal the wound, which has poor effect and is susceptible to pests and diseases. If a protective agent is applied to the wound, it has a bactericidal effect and can form a protective film on the wound to prevent disease and retain water, so that the wound of the fruit tree can heal and repair on schedule and grow better. For example, the summer buds of grapes can branch continuously to form multiple side shoots. The vigorous growth of branches and shoots will compete for fruit nutrients. Applying bud inhibitors on the internodes and branches can inhibit the germination of side shoots in the early stage, saving tree nutrients, while reducing the workload of manual pruning in the later stage, effectively inhibiting the plant's nutritional growth, improving the quality of inflorescences, and promoting the accumulation of nutrients by leaves through photosynthesis.

[0003] At present, in the aspect of rapid shaping of fruit trees, the main method is to orient branches by incising, which has low work efficiency and high requirements for management technology, and the wounds are prone to cause diseases and insect pests. In management measures such as promoting budding, special agents are often used to apply pesticides to fruit trees. There are two main methods. One is to use agricultural sprayers or cup spraying. The speed of large-scale application is fast, but the liquid cannot be sprayed accurately on the site of action, which will cause side effects on fruits or leaves, and the application effect is relatively poor. The large amount of medicine used pollutes the environment, causing waste of the smear, and failing to achieve the expected prevention and control effect; the second is to dip a brush into the medicine bottle, dip the medicine and apply it on the wound surface. Applying a bud requires 3-5 times of application. The mechanical reciprocating dipping and applying operation is also time-consuming and labor-intensive, with low work efficiency and high labor consumption. The dust on the bud is easy to be contaminated on the brush. When dipping again, the dust will enter the bottle with the cotton swab to contaminate the medicine, affecting the effect; at the same time, this operation is also easy to apply the medicine on the hands, which can cause skin infection in severe cases. These methods are complicated and inconvenient to operate, and it is difficult to meet the needs of drug use in various scenarios in cultivation management. When applying pesticides, it is important to "apply them evenly, thoroughly, and sufficiently". There is a great demand in production for tools that can be used for targeted drug use and labor-saving operation.
