Problems solved by technology

For example, the application number 201210206014X, the title of the invention is a Chinese patent of a multifunctional paddy rice yield-increasing foliar fertilizer and its preparation method. In the foliar fertilizer disclosed in this patent, castor oil polyoxyethylene ether, a non-ionic surfactant, is added in an amount of 5 -6%, but the substance has very low solubility and the production process is not efficient
The application number is 201310231728.0, and the invention name is a Chinese patent for the preparation method and application of a selenium-enriched foliar fertilizer, which discloses the addition of anionic surfactant sodium dodecylsulfonate (SDS) in the foliar fertilizer, and the addition amount is 0.5- 1.5%, however, SDS is not easy to be biodegraded in nature and has certain pollution to the environment

preparation example Construction

[0029] The invention also provides a preparation method of the foliar fertilizer.

[0030] The preparation method of the foliar fertilizer of the present invention, weighs 10~20 parts of compound amino acid powders and adds water and stirs to dissolve in parts by weight; Add 8~10 parts of potassium nitrate, 8~14 parts of urea, 12~18 parts of trihydrate Dipotassium hydrogen phosphate, 0.4-0.6 parts of ammonium molybdate, 0.8-1.2 parts of sodium tetraborate are stirred and dissolved to obtain a clear solution; add 3-5 parts of subtilisin sodium and stir to dissolve, add 4-6 parts of sodium humate to dissolve .

Embodiment 1

[0032] Embodiment 1: Leaf surface permeability experiment

[0033] The greater the conductivity, the greater the permeability. The leaves of pakchoi were treated with different concentrations of lipopeptide sodium for 20 minutes, and the electrical conductivity of the leaves was measured. The results are shown in Table 1.

[0034] Table 1 Conductivity results

[0035]

[0036] It can be seen from the results in Table 1 that the permeability of leaves increases with the concentration of lipopeptide sodium increasing.

Embodiment 2

[0037] Example 2: Disease resistance

[0038]The leaves of Chinese cabbage were sprayed with lipopeptide sodium solutions of different concentrations. After 30 minutes, the leaves were cut off and the conductivity of peroxidase and catalase of the leaves were measured. The results are shown in Table 2.

[0039] Table 2 Results of antioxidant capacity

[0040]

[0041] It can be seen from the results in Table 2 that the addition of lipopeptide sodium can effectively improve the antioxidant capacity of pakchoi, thereby helping to improve its defense capacity and enhance its disease resistance.

Abstract

The invention belongs to the field of agricultural fertilizers and discloses a leaf fertilizer containing natural high-activity iturins sodium surfactin and a preparation method of the leaf fertilizer. The iturins sodium surfactin is capable of improving the permeability of cells and the disease resistance of crops, promoting the normal growth of the crops and improving the nutrient absorption of the crops. The leaf fertilizer contains the iturins sodium surfactin, so that the nutrient absorption of the crops is improved, the biomass of the crops is increased; meanwhile, the iturins sodium surfactin can be absorbed and utilized by the crops, has high possibility of being environmentally degraded and is environmentally friendly. The preparation method of the leaf fertilizer is simple in operation and applicable to industrial production.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, in particular to a foliar fertilizer, in particular to a foliar fertilizer containing subtilisin sodium and a preparation method of the foliar fertilizer. Background technique [0002] The development of planting in agricultural production is inseparable from fertilizers. Fertilizer is a kind of substance that provides one or more essential mineral elements for plants, improves soil properties and improves soil fertility level, and is one of the material basis of agricultural production. In recent years, with the development of fertilization technology, foliar fertilization has been rapidly promoted and applied as a fertilization measure to strengthen the nutrition of crops and prevent certain deficiency symptoms. Practice has proved that compared with soil fertilization, foliar fertilization is a technology that directly applies various nutrients needed by crops to the foliage, and has t...
