The invention discloses a saline-alkali soil modifier and a preparation method and application thereof, and belongs to the field of saline-alkali soil improvement, and the preparation method comprises the following steps: S1, extracting fulvic acid mixed liquor from weathered coal in the Nouth Lake of Hami Da in Xinjiang; s2, the fulvic acid mixed solution is graded to obtain F1-grade fulvic acid-F4-grade fulvic acid, and the molecular weight of the F1-grade fulvic acid is 1t; 500 is smaller than or equal to F2-grade fulvic acid molecular weight 1t; the molecular weight of F3-grade fulvic acid is larger than or equal to 1000 and smaller than or equal to 2500, and the molecular weight of F4-grade fulvic acid is gt; 2500: F1-grade fulvic acid or / and F2-grade fulvic acid is the saline-alkali soil modifier. The modifier can obviously improve the physical and chemical properties of soil, also has a certain increase in the contents of soil nutrient organic matters, hydrolytic nitrogen quick-acting phosphorus and quick-acting potassium, and has significant effects on improving the seedling emergence of crops, promoting the growth of the crops and increasing the yield of the crops.

This invention discloses a dry heat treatment method for tomato seeds to enhance seed vigor and extend storage life, relating to the field of tomato seed storage technology. The method includes: selecting mature, plump, and undamaged commercial tomato seeds with consistent maturity and maintaining appropriate moisture content; placing the pre-treated seeds in a single layer on a tray and placing it in a dry heat treatment device, performing dry heat treatment sequentially according to a preset program; comparing the germination indicators of dry heat-treated and untreated seeds to determine the effect of the dry heat treatment; and sealing and storing tomato seeds with qualified germination rates. This invention, through precisely controlled stepwise heating and high-temperature constant-temperature sterilization, effectively activates the seed's internal repair enzyme system while inhibiting metabolic processes that lead to seed deterioration, avoiding physical or physiological damage to the seeds caused by high-temperature treatment, and effectively preventing seed coat cracking, radicle burn, or excessive dehydration.
