Embodiment 1

[0024] Embodiment 1, a kind of method of preventing and controlling citrus aphid with grass, comprises following prevention and control measures:

[0025] Before the citrus trees shoot, sow nightshade grass in the citrus orchard to attract aphids. According to the climatic conditions in Fujian Province, generally 15-30 days before the spring or autumn shoots of citrus trees germinate, dig strip-shaped trenches or dig 3-5 holes between every two citrus trees in the citrus orchard, and apply calcium, magnesium, phosphorus, After the organic fertilizer is mixed with the soil evenly, sow 5-10 seeds (or 2-5 seeds per hole) of Solanum nigrum in strip furrows, cover with soil and water them properly. Or when the autumn shoots start to germinate, the interplanted nightshade grass grows to a height of not less than 15cm, and there are more than 2 pairs of alternate leaves. If there are aphids at this time, the aphids only eat the tender leaves of nightshade grass and do not harm the y...

Embodiment 2

[0026] Embodiment 2: a kind of method of preventing and controlling Guanxi honey pomelo aphid with grass, comprises following prevention and control measures:

[0027] Plant grass to prevent and control Guanxi honey pomelo aphids before the spring shoots germinate, sow nightshade grass in the Guanxi honey pomelo orchard, and plant grass to attract aphids. According to the climatic conditions of the southern provinces, generally in early and mid-February, dig strip-shaped trenches or dig 3 to 5 holes between every two pomelo trees in the Guanxi honey pomelo orchard, apply calcium, magnesium, phosphorus, organic fertilizer and mix with the soil After uniformity, sow 5-10 (or 2-5 per hole) Solanum nigrum seeds in strip furrows, cover with soil and water. If it is sunny for more than 5 consecutive days after sowing, it needs to be watered in time. It is best when the spring shoots of the Guanxi honey pomelo tree start to germinate. . If there are aphids at this time, the aphids ...

Embodiment 3

[0028] Embodiment 3: a kind of method of preventing and controlling navel orange aphid with grass, comprises following prevention and control measures:

[0029] Plant grass to prevent and control navel orange aphids before the germination of winter shoots, sow nightshade grass in the navel orange orchard, and plant grass to attract aphids. According to the climatic conditions of the southern provinces, generally in the middle and late July, dig a strip-shaped ditch or dig 3 to 5 holes between every two navel orange trees in the navel orange orchard, apply calcium, magnesium, phosphorus, organic fertilizer and mix with the soil evenly, Sow 5-10 (or 2-5 per hole) Solanum nigrum seeds in strip furrows, and water them after covering with soil. If it is sunny for more than 5 consecutive days after sowing, it needs to be watered in time. It is best when the winter shoots of the navel orange tree start to germinate. If there are aphids at this time, the aphids will only eat the youn...

Abstract

The invention relates to a method controlling citrus aphids with grass. The method includes grass class selection, aphid trapping through grass cultivation and aphid elimination through grass cutting. According to the invention, before citrus trees sprout, solani nigri herba is planted in a citrus garden for trapping aphids, so that the aphids do not injure the tender branches of the citrus trees. After leaves of the branches of the citrus tree unfold completely, the solani nirgri herba is cut off and dried, so that the aphids lose food and die. The method has a distinctive advantage that pesticides are not needed for aphid control in the citrus garden, so that the biological safety is ensured; the aphid control effect is obvious; the method is simple in structure, easy to implement and promote, stable in control effect, free of toxic and side effects, free of public dangers, zero pollution, low in investment, quick in action, suitable for large area promotion and application and distinctive in social economic benefit and biological benefit.

Description

technical field [0001] The invention relates to a method for preventing and controlling citrus pests, in particular to a method for controlling citrus aphids with grass, which belongs to the technical field of plant protection. Background technique [0002] China's citrus planting industry is developing rapidly, and its citrus planting area and output both rank first in the world. With the rapid expansion of citrus planting area, various pests are also increasing. For example, there were few pests in spring shoots of citrus in the past, but aphids often broke out in recent years, which seriously threatened the flowering and fruit setting of citrus. environment and increase production costs. [0003] To explore a prevention and control method that does not need to spray pesticides and can avoid the damage of citrus shoots by aphids can effectively reduce the use of pesticides, which is conducive to the construction of pollution-free and ecological citrus gardens, and will pr...
