Embodiment 1

[0024] Example 1. A method for preventing and controlling citrus aphids by grass, including the following prevention and control measures:

[0025] Before citrus tree shoots, sown nightgrass in citrus orchard to attract aphids. According to the climatic conditions in Fujian Province, generally 15 to 30 days before the spring or autumn shoots of citrus trees germinate, in the citrus orchard every two citrus trees are digging a strip of trench or digging 3 to 5 holes, and applying calcium, magnesium, phosphorus, After the organic fertilizer is mixed with the soil, 5-10 seeds (or 2-5 per hole) of Solanum grass seeds are sown in the strip trench, and the soil is covered and then watered, properly managed, preferably in the spring of citrus trees Or when the autumn shoots begin to sprout, the intercropped Solanum grass grows to a height of no less than 15cm and has more than 2 pairs of alternate leaves. If there are aphids at this time, the aphids only feed on the young leaves of nig...

Embodiment 2

[0026] Example 2: A method for preventing and controlling Guanxi honey pomelo aphids with grass, including the following prevention and control measures:

[0027] Plant grass to prevent and control Guanxi honey pomelo aphids before spring shoots germinate, and sow Solanum grass in Guanxi honey pomelo orchard to attract aphids. According to the climatic conditions of the southern provinces, generally in early and mid-February, in Guanxi honey pomelo orchard every two pomelo trees dig a strip of trench or dig 3-5 holes, apply calcium, magnesium, phosphorus, organic fertilizer and mix with the soil After uniformity, sown 5-10 seeds (or sown 2-5 seeds per hole) of Solanum grass seeds in the strip groove, and cover with soil and then water. After sowing, if it is sunny for more than 5 consecutive days, you need to water in time. It is best when the spring shoots of Guanxi honey pomelo trees begin to sprout. The height of the intercropped Solanum grass is not less than 15cm, and there ...

Embodiment 3

[0028] Example 3: A method for preventing and controlling navel orange aphids with grass, including the following prevention and control measures:

[0029] Plant grass to prevent and control navel orange aphids before the winter shoots germinate, sow nightgrass in navel orange orchards to attract aphids. According to the climatic conditions of the southern provinces, generally in mid-to-late July, dig a strip of trench 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. Sow 5-10 seeds (or sown 2-5 seeds per hole) of Solanum Solanum seeds in the strip groove, and water them after covering with soil. After sowing, if it is sunny for more than 5 consecutive days, water it in time. It is best when the navel orange tree starts to sprout in winter. The intercropped Solanum grass can grow to a height of more than 15cm and have more than 2 pairs of alternate leaves. If there...

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 insect pests, in particular to a method for preventing and controlling citrus aphids by grass, and belongs to the technical field of plant protection. Background technique [0002] China's citrus planting industry is developing rapidly, and the citrus planting area and output rank first in the world. With the rapid expansion of the citrus planting area, various pests are becoming more and more serious. For example, in the past, citrus spring shoots were less harmful to pests. In recent years, there have been frequent outbreaks of aphids, which seriously threaten the flowering and fruit setting of citrus, and increase the use of pesticides. Environment, and increase production costs. [0003] Exploring a prevention and control method that does not need to spray pesticides and can prevent the new shoots of citrus from being damaged by aphids can effectively reduce the use of pesticides, wh...
