The invention discloses novel tea polyphenol induction salt-tolerant application, seed soaking solution and a salt-tolerant method for wheat seedlings. The wheat seedlings are irrigated with the seed soaking solution in salination environments when the wheat seedlings grow and the heights of the wheat seedlings reach 10 cm. The salt-tolerant method includes 1), disinfecting wheat seeds; 2), repeatedly thoroughly washing the disinfected wheat seeds in distilled water; 3), accelerating germination of the wheat seeds; 4), irrigating the wheat seedlings with the seed soaking solution for continuous three days when the wheat seedlings grow and the heights of the wheat seedlings reach 10 cm. The seed soaking solution contains tea polyphenol, and the content of the tea polyphenol is 10-40 micrograms / mL. The novel tea polyphenol induction salt-tolerant application, the seed soaking solution and the salt-tolerant method have the advantages that degradation of chlorophyll in leaves of the wheat seedlings can be obviously deferred under salt-stress conditions, the activity of CAT (catalase) and POD (peroxidase) can be improved, the proline content can be increased, accumulation of membrane lipid peroxidation products MDA can be reduced, and the salt-stress resistance of the wheat seedlings can be ultimately improved.

The invention relates to a composition containing 5-ALA and mycose and a leaf fertilizer prepared by using the composition. The composition for preparing the leaf fertilizer contains 2000-4000 parts by weight of mycose and 0.5-1 part by weight of 5-ALA. According to the leaf fertilizer containing 5-ALA and mycose, the concentration of the mycose is 2-4g / L, and the concentration of the 5-ALA is 0.5-1mg / L. The 5-ALA and the mycose are compounded at specific concentration, and multiple nutrient elements at specific concentration are used to prepare the compound leaf fertilizer. The 5-ALA and the mycose are synergized and can enhance the content of chlorophyll in the blade in comparison with separately using 5-ALA and the mycose, the photosynthesis of multiple crops is promoted, particularly under adverse situation, the stress resistance of crops can be remarkably enhanced, the growth of plants is greatly promoted, and the yield and quality of crops are improved by maintaining the stability of cells, lowering membrane lipid peroxidation and other physiological ways.

The invention belongs to the technical field of agricultural production, and particularly relates to a cold-resistant agent for brassica rapa L. The cold-resistant agent for the brassica rapa L. seedlings is mainly characterized by comprising raw materials as follows: 15-25 mg / L of ABA (abscisic acid) and the balance of water, wherein the purity of the ABA (abscisic acid) is higher than or equal to 99.9%. The cold-resistant agent aims to solve the problem that the brassica rapa L. in the northern cold and arid regions is vulnerable to low-temperature freezing damage, growth of the overground part and the root system of the brassica rapa L. is promoted with chemical control means, especially the thickening growth of roots, the outstanding performance refers to increase of dry matter accumulation, and safe wintering of the brassica rapa L. is guaranteed; meanwhile, permeability (relative electrical conductivity) of leaf cell membranes as well as accumulation of membrane lipid peroxidation malonaldehyde can be reduced, so that the low-temperature freezing degree of leaves of the brassica rapa L. is reduced, the cold resistance of the brassica rapa L. is remarkably improved, and the cold-resistant agent has great practical significance on brassica rapa L. production.
