preparation example Construction

[0023] The extract is made from just-harvested lentils and Polygonum punctatus together with roots, stems and leaves. The preparation method comprises the following steps:

[0024] ⑴Collect the unicorns and Polygonum spp. together with the roots, stems and leaves, remove impurities and wash them for later use;

[0025] (2) Add the product of step (1) into the pulverizer to squeeze the juice;

[0026] (3) Filter the solid-liquid mixture after squeezing the juice, filter out the residue, and add potassium sorbate with a liquid weight of 0.35‰ to make an extract.

Embodiment 1

[0028] Select 6 acres of cabbage planting land, divide it into three groups, each group is 2 acres, named A, B, and C respectively; A, B, and C have the same soil composition and pH, and the temperature, humidity, wind force, The light is the same, the water source is the same, and the field is managed in the same way.

[0029] The same cabbage variety was grown in A, B, and C, and the plants were planted at the same density and managed in the same way.

[0030] A uses the medicament of the present invention, B uses traditional chemical medicament, and C does not use any medicament.

[0031] In A: the raw materials are unicorns, Polygonum punctatus and roots, stems and leaves, and they are used in the following way:

[0032] (1) Mix the extract with water at a weight ratio of 1:10-11, then add 0.1% washing powder to prepare a spray;

[0033] ⑵When controlling aphids, choose a sunny day to spray the whole plant 1 or 2 times in the morning and evening, with a dosage of 45 kg p...

Embodiment 2

[0040] Select 3 greenhouses for planting celery, and each greenhouse is one mu of land; they are divided into three groups, each group is one mu, and one of the greenhouses is named A, the other greenhouse is named B, and the other greenhouse is named C; A, B The soil composition and pH are the same as those of C, the species are the same, the temperature, humidity, wind force, and light in the area are the same, the water source is the same, and the greenhouse is managed in the same way.

[0041] Shed A uses the medicament of the present invention, Shed B uses traditional chemical medicament, and Shed C does not use any medicament.

[0042] The control effect of shed A was 99.6%, and the aphids in the whole crop were completely prevented and controlled.

[0043] The prevention and control effect of shed B is about 90.2%, and the recurrence rate is relatively high.

[0044] In C, a large area of ​​production is reduced, and some celery has no commercial value.

[0045] Accor...

Abstract

The invention relates to a botanical medicine for preventing and treating aphids of crops. The raw material of the botanical medicine is a Lepidium apetalum and Polygonum glabrum extract liquid, and the extract liquid contains an antiseptic. Rhizomes and leaves of Lepidium apetalum and Polygonum glabrum are adopted as raw materials and are juiced to obtain the extract liquid, the extract liquid is diluted with water, and the diluted extract liquid is sprayed on crops in order to realize a prevention effect when no aphids exist in the crops and realize a very good treatment effect when the aphids exist in the crops; a field test result shows that the prevention and treatment effect reaches 98% or above; the extract liquid can prevent and treat the aphids, and also can obviously prevent and treat thrips, red spiders and other piercing and sucking pests; and Lepidium apetalum and Polygonum glabrum are wild vegetables and can be eaten, so drug residual and environmental pollution problems do not appear in the practical use process, thereby harms of pests are reduced, and the yield increases by 5-8%.

Description

technical field [0001] The invention belongs to the technical field of crop aphid prevention and control, in particular to a method for preventing and treating aphids by using extracts of leaves and capsicum. Background technique [0002] Aphids, also known as honey bugs, greasy insects, etc., mostly belong to the family Aphididae of the order Homoptera, and are pests with piercing and sucking mouthparts. They often cluster on leaves, tender stems, flower buds, terminal buds, etc., sucking juice and causing leaves to shrink. , curly, deformed, causing branches and leaves to wither or even the death of the whole plant in severe cases. The honeydew secreted by aphids can also induce soot and spread viral diseases and other hazards. Aphids are small and soft, with tubular protrusions on the abdomen, and they suck plant juice. Due to the strong fecundity of aphids, female aphids can give birth soon after birth, and can reproduce 10 to 30 generations a year. The generation overl...
