Embodiment 1

[0018] Formula: ectoine 400g / L, γ-aminobutyric acid 20g / L, mannitol 10g / L, potassium dihydrogen phosphite 250g / L, distilled water to 1L.

[0019] Preparation:

[0020] A, first dissolve ectoine in water to prepare a solution;

[0021] B, then dissolving gamma-aminobutyric acid in the solution in step (A), stirring slowly until dissolving;

[0022] C, mannitol is dissolved in the solution in step (B) again, agitate slowly, until dissolving;

[0023] D, then potassium dihydrogen phosphite is dissolved in the step (C) completely in the mode of intermittent feeding;

[0024] E. Finally, distill the liquid in step (D) to 1 L with distilled water, and mix thoroughly to obtain a special foliar fertilizer for saline-alkali land containing ectoine.

Embodiment 2- Embodiment 6

[0026] The raw materials and proportions of Embodiment 2 to Embodiment 6 of the present invention are shown in the following table.

Abstract

The invention discloses a ectoine-containing special foliar fertilizer for saline-alkali soil as well as a preparation method and application of the foliar fertilizer. The foliar fertilizer is prepared by taking ectoine as a main effective component, taking ectoine and gamma-aminobutyric acid as stress resistance factors and mannitol and monopotassium phosphate as fertilizer synergists, is used for foliar spraying in a seedling stage and a mature stage of saline-alkali soil crops, and is verified by indoor pot culture experiments and field plot experiments. The problems that crops are not easyto survive and grow slowly in saline-alkali soil are solved, the content of free proline in the crops and the expression of an antioxidant enzyme system can be remarkably improved, and the yield increase of the crops and the improvement of the quality of the crops are promoted.

Description

technical field [0001] The invention belongs to the technical field of foliar fertilizers, and specifically relates to a special foliar fertilizer for saline-alkali land containing ectoine, a preparation method of a special foliar fertilizer for saline-alkali land containing ectoine, and a method for preparing a special foliar fertilizer for saline-alkali land containing ectoine. The special foliar fertilizer for saline-alkali land of hydropyrimidine is used in improving crop yield and crop quality on saline-alkali land. Background technique [0002] In recent years, with the development of agriculture, fertilizers have gradually changed from the generality of crops to the specificity and functionality of crops. Compared with traditional fertilizers, foliar fertilizers can provide nutrients to crops more quickly and efficiently through the leaves, or change the signal pathway of crops to improve the stress resistance of crops. [0003] Saline-alkali land means that the soil...
