Embodiment Construction

[0015] Hereinafter, the above-mentioned and other technical features and advantages of the present invention will be described in more detail.

[0016] The main process of the method for the present invention to kill fig overwintering bovine larvae is:

[0017] Step a, in spring, before the buds of fig branches germinate, cut off all aboveground branches from near the ground, leaving only short piles of about 10 cm, and then crush the branches with a plant grinder to kill the beetle pest in the branches. Crushed fig branches can be used as a culture substrate for the production of edible fungi.

[0018] Step b, use general farmland water, such as river water, pond water or tap water, etc. to submerge the soil of the orchard and the short piles of figs in the water, keep it for 12-24 hours, and then remove the accumulated water in the orchard, and then parasitize on the roots and branches of figs. Overwintering cattle larvae in the dry can be killed by smothering them all.

Abstract

The invention relates to a method for killing fig overwintering longicorn larvas. The method specifically comprises the steps that firstly, in spring, all overground branches are wiped out before fig branch buds germinate, and longicorn pests in the branches are killed; secondly, orchard soil and fig short stumps are immersed in general farmland water, accumulated water in an orchard is drained, and therefore all the parasitism overwintering longicorn larvas in fig roots and branches can be suffocated and killed. According to the method, the manual eliminating method and the physical suffocating method are adopted to kill the fig overwintering longicorn larvas, chemical pesticide is not used at all, and the method has the advantages of being friendly to the environment, simple and easy to apply.

Description

technical field [0001] The invention relates to the field of plant protection, in particular to a method for killing fig overwintering bovine larvae. Background technique [0002] Fig (Ficus carica L.) is a perennial deciduous woody fruit tree in subtropical to warm temperate zone. Under natural conditions, it can grow into a large tree with a height of 5-8 meters, while under artificial intensive cultivation conditions, the height of fig trees is generally controlled within 2 meters. The growth and fruiting characteristics of figs are different from those of ordinary fruit trees. Its flower buds are divided into two types, one is differentiated in the autumn of the previous year, and is usually distributed at the top of the branches. As the temperature rises in spring, these flower buds gradually develop and mature in June-July of that year, which is the so-called "summer fruit". The second flower buds began to differentiate in the spring of that year. With the germinat...
