Embodiment 1

[0027] The present embodiment provides a kind of highly resistant daylily disease and insect pest preparation, by mass percentage, comprises the following components:

[0028]

[0029] In this example, the preparation method of the Sophora flavescens extract is as follows: add Sophora flavescens into ethyl acetate at 48°C, soak for 20 minutes, pass through a 100-mesh sieve after high-speed beating, filter out impurities, and adjust the pH to 7.0 -7.5, add 0.3% protease of Sophora flavescens mass, hydrolyze at 38°C for 12min, and cool to room temperature. The solid-to-liquid ratio of said flavescens ethyl acetate is 1:6g / ml. The added amount of the protease is 0.1% of the mass of the Sophora flavescens.

[0030] In the present embodiment, the preparation method of the highly resistant daylily pest preparation specifically includes the following steps:

[0031] (1) Add imidacloprid and chitosan in proportion to 2 / 3 of deionized water, heat and stir in a water bath at 30°C f...

Embodiment 2

[0037] The present embodiment provides a kind of highly resistant daylily disease and insect pest preparation, by mass percentage, comprises the following components:

[0038]

[0039] In this example, the preparation method of the Sophora flavescens extract is as follows: soak Sophora flavescens in ethyl acetate at 50°C for 15 minutes, pass through a 100-mesh sieve after high-speed beating, filter out impurities, and adjust the pH to 7.0 -7.5, add 0.2% protease of Sophora flavescens mass, hydrolyze at 42°C for 12 minutes, and cool to room temperature. The solid-to-liquid ratio of said flavescens ethyl acetate is 1:6g / ml. The added amount of the protease is 0.2% of the mass of the Sophora flavescens.

[0040] In the present embodiment, the preparation method of the highly resistant daylily pest preparation specifically includes the following steps:

[0041] (1) Add imidacloprid and chitosan in proportion to 2 / 3 of deionized water, heat and stir in a water bath at 35°C for...

Embodiment 3

[0047] The present embodiment provides a kind of highly resistant daylily disease and insect pest preparation, by mass percentage, comprises the following components:

[0048]

[0049] In this example, the preparation method of the Sophora flavescens extract is as follows: soak Sophora flavescens in ethyl acetate at 48°C for 20 minutes, pass through a 100-mesh sieve after high-speed beating, filter out impurities, and adjust the pH to 7.0 -7.5, add 0.3% protease of Sophora flavescens mass, hydrolyze at 38°C for 12min, and cool to room temperature. The solid-to-liquid ratio of said flavescens ethyl acetate is 1:6g / ml. The added amount of the protease is 0.1% of the mass of the Sophora flavescens.

[0050] In the present embodiment, the preparation method of the described highly resistant day lily disease and insect pest preparation specifically includes the following steps:

[0051] (1) Add imidacloprid and chitosan in proportion to 2 / 3 of deionized water, heat and stir in...

Abstract

The invention discloses a high-resistance day lily disease and insect pest preparation and a preparation method thereof. The high-resistance day lily disease and insect pest preparation is prepared from the following components in percentage by mass: 0.5-2% of imidacloprid, 15-20% of chitosan, 1.5-3% effective microorganisms (EM), 10-16% of a radix sophorae flavescentis exract, 6-10% of biochemical potassium fulvic acid, 10-15% of hydroxymethyl cellulose, 5-8% of methylenesuccinic acid, 0.5-2% of an emulsifier, 0.2-1% of a dispersant, 0.2-1% of a defoamer and the balance of deionized water. According to the high-resistance day lily disease and insect pest preparation, the metabolism of the plant can be enhanced by strengthening the mutual gain between components can be strengthened, the cuticle of a protective film on the day lily surface can be strengthened, and pathogenic bacteria are prevented from entering. The preparation can not decompose in the body of herbivorous pests, the death of the pests is caused due to physiological blight, the day lily growth is promoted, and the daylily yield and quality are improved; and the preparation method is simple, a storage period can be upto 16 months in a sealed environment, and good market prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a daylily pest preparation, in particular to a highly resistant daylily pest preparation and a preparation method thereof. Background technique [0002] Day lily, also known as day lily, forget worry grass, and brain-invigorating vegetable, is a perennial herbaceous plant of the genus Hemerocallis in the family Liliaceae. Its edible part is the flower bud that has not yet been released, and the flower bud is rich in sugar, protein, vitamin C, calcium, fat, carotene, amino acid and other nutrients necessary for the human body, and its nutritional value is very high. The nature and taste of day lily are sweet and cool, and it also has the effects of hemostasis, anti-inflammatory, heat-clearing, dampness, digestion, eyesight, nerves, brain, anti-aging and so on. According to other studies, day lily also has various health functions such as lowering fat, lowering blood pressure, a...
