Problems solved by technology

[0005]Plant spider mites have serious damage to many plants, especially fruit trees, and can cause serious plant death. At present, most of them are controlled by chemical pesticides such as acaricides. The perennial application of mite control agents is easy to use and cause resistance of harmful mites. Therefore, more and more mite control agents are not effective, and the large-scale application of mite control agents will bring serious harm to the environment and the safety of agricultural products.

Embodiment 1

[0043] The preparation method of ferrous gluconate comprises the following steps:

[0044] (1) Dissolve gluconic acid in water, add water equal to the mass of gluconic acid, add excess iron powder to react at room temperature, after the gas generated by the reaction becomes less, heat the reaction system to boiling to make the reaction complete, and filter immediately;

[0045] (2) After the temperature drops to normal temperature, ferrous gluconate with a mass of 0.05% of the filtrate is put in as a seed crystal for rapid crystallization;

[0046] (3) Dry the crystals under negative pressure at 60°C until the crystals harden, then raise the temperature to 110°C and air-dry for 2 hours, crush them and sieve them with a size of not less than 60 mesh.

[0047] Then the ferrous gluconate and the ethoxy modified trisiloxane are in mass ratio 5: 1 (in the mixture, the iron mass ratio contained in the ethoxy modified trisiloxane and the ferrous gluconate is 1:0.6) mix well, a...

Embodiment 2

[0053] In late July 2012, mix ferrous gluconate and ethoxy-modified trisiloxane evenly at a mass ratio of 10:1, dilute 400 times with water, and spray evenly on iron-deficient pear trees with yellowed leaves, at intervals of 7 Spray once a day and spray 3 times in total. After 20 days after the first spray, there is an obvious regreening effect. After 45 days, the leaves grow normally. Effect picture see Figure 7 , Figure 8 shown.

Embodiment 3

[0055] At the end of October 2011, gardenias with iron deficiency symptoms were selected, and the yellowing was more serious in the fertilized area, see Figure 9 , Figure 9 The left part is the effect picture of the fertilized area before fertilization, and the right part is the effect picture of the unfertilized area as the control group at the same period. Mix ferrous gluconate and ethoxy-modified trisiloxane evenly at a mass ratio of 20:1, add water to dilute 150 times, and spray evenly on the leaves of gardenia in the fertilization area, spray once every 7 days, and spray 3 times in total 20 days after the first spraying, the fertilized area had obvious regreening phenomenon; after 45 days, the fertilized area obtained a good regreening effect, and the growth tended to be normal, while the yellowing of the unfertilized area increased, such as Figure 10 as shown, Figure 10 The left part is the effect map of the fertilized area, and the right part is the effect map of ...

Abstract

The invention provides a medicine for plant leaf surfaces, which is characterized by comprising ferrous gluconate. The medicine can exist and play effectiveness stably in a plant cell environment, is high in iron supplementing effect, has favorable stability, and can obviously reduce and control harm caused by plant spider mites. Moreover, the raw materials of the medicine are low in price and easy to obtain; the preparation and the application are convenient; and the medicine is safe for people and livestock, and cannot pollute the environment.

Description

technical field [0001] The invention relates to a plant medicine, a preparation method and an application method. Background technique : [0002] In the soil under neutral or alkaline conditions, the iron element often exists in an insoluble state, so although the total iron content in the soil is high, the effective iron content is very low, which cannot meet the needs of plant growth, especially for some plants that require more iron. High plants often cause iron deficiency and chlorosis of plants. The light ones show chlorosis and yellowing between the veins, and obvious green reticular patterns appear. In severe cases, the whole leaf is albino, the photosynthesis of the plant is significantly reduced, and the growth of the plant is weak, which often reduces the yield and quality of the crops. [0003] At present, there are three ways to supplement iron to plants, one is through soil application, the other is plant foliar spraying, and the other is trunk strong injectio...
