Description

A kind of guava cultivation method and pest trapping device

technical field

The invention relates to the technical field of agricultural planting, in particular to a guava cultivation method and a pest trapping and killing device.

Background technique

Guava is a tropical fruit tree, native to tropical America. It belongs to Myrtaceae guava. It is an evergreen small tree or shrub, commonly known as guava seed and Naba. Because it comes from abroad, it is called guava, which is one of the subtropical famous fruit varieties. Guava has strong growth adaptability, no choice of soil, and easy cultivation. However, during the planting process, the frequency of pests and diseases is high, which seriously affects the quality and yield. Therefore, it is very important to summarize the methods of integrated pest management of guava.

The main pests of guava are flower thrips, scale insects, fruit flies and so on.

Fruit fly adults lay their eggs in the guava peel, and after hatching, the larvae bore damage in the fruit, causing rot and early shedding of the fruit. In severe cases, the losses are enormous. In July-August, the number of insect populations is the largest, the generation overlap is serious, and there is no strict overwintering process. In southwestern Guangxi, 8 to 10 generations occur in a year, and they can occur every anniversary.

Control methods for fruit flies during guava cultivation include:

Physical control. The fruit is bagged to prevent the adult insects from laying eggs. At the young fruit stage and before the fruit fly adults lay eggs, the fruit is bagged and sprayed with 40% chlorpyrifos EC before bagging.

Drug control. In 69 months, use 800 times liquid of 40% chlorpyrifos EC, add 0.5kg of white sugar to every 50kg of the prepared liquid and spray it on the orchard weeds to trap and kill adults. After the harvest of guava each season, spray 40% chlorpyrifos EC or 800 times liquid of 45% phoxim EC on the canopy ground.

The above methods require a lot of manpower, and all use pesticides, which are detrimental to human health. In the prior art, a method of inducing and killing is generally used at the same time, that is, hanging insect traps, and guiding pests such as fruit flies into the container for killing. The insect traps in the prior art generally only have 3 or 4 induction ports located above the tank body, and the induction ports are set in a roundabout shape, so that it is difficult for pests to escape after entering the tank body. However, the circuitous structure makes it difficult to clean the trap, and there is still a risk of pests escaping due to the large cross-sectional area of the channel. In addition, the number of induced openings is small, and the outer dimension of the induced openings is small, so it is difficult for pests to find the entrance, and the effect of trapping pests is very limited.
