Abstract

The invention provides water-soluble fertilizer for reinforcing the cold resistance of crops, as well as a preparing and using method thereof. The water-soluble fertilizer is prepared from the following raw materials in parts by weight: 300-320 parts of urea, 100-130 parts of monopotassium phosphate, 25-30 parts of diammonium hydrogen phosphate, 40-60 parts of bladder-wrack extract, 1-3 parts of vitamins, 5-7 parts of proline, 8-10 parts of glycine betaine, 10-12 parts of sorbitol, 4-6 parts of EDTA-Ca, 1-3 parts of DTPA-Fe, 1-2 parts of EDTA-Zn, 2-3 parts of disodium octaborate tetrahydrate,2-4 parts of nano-silicon sol, 10-15 parts of a pH regulator, 2-3 parts of stabilizer, 8-10 parts of surfactant and the balance of water. The water-soluble fertilizer can be used for effectively reinforcing the low-temperature stress resistance of crops to reduce output reduction caused by cold damage; and the method is simple in preparation steps, is applicable to large-scale industrial production application, is convenient to sue, and is favorable to popularization.

Description

technical field [0001] The invention relates to the technical field of production of functional water-soluble fertilizers, in particular to a water-soluble fertilizer that enhances the cold resistance of crops and its preparation and use methods. Background technique [0002] Low temperature stress is one of the main environmental stresses affecting crop yield and quality worldwide. Low temperature stress will lead to damage of crop plasma membrane, cell dehydration and metabolic disorder, which will seriously affect the growth of crops; even when the low temperature stress exceeds the control range of plants, crops will often die. The cold resistance of crops is a genetic characteristic formed by crops adapting to low temperature environment for a long time. It is closely related to external environmental conditions (including climate, soil fertility, crop growth), endogenous hormones and osmotic adjustment substances in crops, and crop physiological conditions.
