Problems solved by technology

The conventional way to prevent mites is to use organophosphorus acaricides, which have a certain effect on mites, but if they are used frequently, their effect on mites will be significantly reduced, because mite pests are harmful to mites. Any medicine has strong drug resistance. In addition, the use of chemical agents to kill mites will also cause phytotoxicity to the leaves of arrowroot, making it unable to grow normally, and the plants will mutate, and the leaves will deform and become smaller. For arrowroot, which is mainly for foliage viewing, if there is a problem with the leaves, it means that the value of its products is declining

Embodiment 1

[0007] Introduce ladybug larvae from the Netherlands around May to June, and feed them with oat grass in a corner of the greenhouse. When the incidence of mite pests is high in winter, distribute the oat grass over 5000m 2 Different places in the greenhouse, every 1000m 2 Put about 6,000 ladybugs, then gently shake off the ladybugs attached to the oat grass, remove the oat grass, and let the ladybugs find food by themselves, so that the ladybugs will find mites and eat the mites. When the mite pests are extinct, place oat grass in different places in the greenhouse. At this time, the ladybugs will also find edible oat grass because they have no food, and gather the oat grass placed in different places together to play a role. The purpose of recycling ladybugs. Do not use any chemical pesticides in the greenhouse where ladybugs are used to prevent mites. The existing supporting technology of arrowroot cultivation using ladybugs to prevent and control acarid pests is: temperat...

Abstract

The invention belongs to the field of a biological control technology of arrowroot. The biological control technology of the arrowroot is realized in such a way that the larvae of more than 30000 ladybugs are bred by oat grass at one corner selected in each 5000m<2> of greenhouse; and when the incidence of mite pests is high at the seasons of spring and winter, the oat grass with the ladybugs is distributed at different places in the greenhouse, about 6000 ladybugs are placed at every 1000m<2>, then the ladybugs on the oat grass are lightly shaken off, and the oat grass is taken off. By using the invention to prevent and treat mites, the experiments of 3 years are continuously carried out in the greenhouse in which the arrowroot is planted, the effect of the invention is very obvious, a plant is free from the large-area damage of the mites, the leaves of the plant are healthy, and the malformation of the leaves, the yellowing, the diminishing of the leaves of the plant and the like do not occur. The invention can punctually supply a product for marketing according to a production plan.

Description

technical field [0001] The invention belongs to the field of biological pest control for plant cultivation, in particular to the technical field of arrowroot biological control. Background technique [0002] Arrowroot is an ornamental foliage plant, and it is one of the popular high-end flowers at present. Because arrowroot is cultivated in a greenhouse, the annual temperature is moderate, and the air humidity is high, so mites are prone to occur, especially in winter with poor ventilation. Arrowroot leaves that have been damaged by mite pests are spotted and yellowed, and in severe cases, the leaves are deformed. The conventional way to prevent mites is to use organophosphorus acaricides, which have a certain effect on mites, but if they are used frequently, their effect on mites will be significantly reduced, because mite pests are harmful to mites. Any medicine has strong drug resistance. In addition, the use of chemical agents to kill mites will also cause phytotoxicit...
