Problems solved by technology

[0004] Underground pests feed on potato tubers, causing serious economic losses in production
However, in production, the existing control methods for underground potato pests mainly use highly toxic and high-residue chemical pesticides to kill them, causing serious pollution to the ecological environment.

Abstract

The invention discloses a water-soluble fertilizer capable of enhancing disease and pest resistance of potatoes, which is prepared from the following raw materials in percentage by weight: 18-22% of ammonium nitrate, 8-9% of potassium chloride, 8-10% of monoammonium phosphate, 45-55% of potassium nitrate, 5-7% of ammonium chloride, 2-3% of potassium dihydrogen phosphate, 1.4-2% of sodium borate pentahydrate, 0.2-0.4% of zinc chelate, 0.2-0.4% of iron chelate, 0.2-0.3% of copper chelate, 0.3-0.5% of gamma-polyglutamic acid, 0.5-1.5% of jasmonic acid, 1-2% of Tween, 0.3-1.5% of compound sodium nitrophenolate and 0.7-0.9% of auxiliary material. The invention also discloses an application method of the water-soluble fertilizer capable of enhancing disease and pest resistance of potatoes. The water-soluble fertilizer can promote potato growth, increase the yield, enhance the disease and pest resistance of potatoes, reduce the hazard of grubs and other soil pests, enhance the stress tolerance, improve the quality and optimize the ecology, thereby being a resource-saving environment-friendly product.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a water-soluble fertilizer for improving the ability of potatoes to resist pests and diseases and an application method thereof. Background technique [0002] Potatoes are the fourth largest food crop in the world, second only to rice, wheat and corn. Potatoes are often subject to various hazards during cultivation. Potato late blight and underground pests are the most serious pests and diseases that harm potatoes, and they generally occur in potato-producing areas of the world. . [0003] Exogenous jasmonic acid acts as an elicitor to improve the resistance of potato to late blight, as shown in: exogenous jasmonic acid can enhance the activity of resistance-related enzymes in potato leaves; exogenous jasmonic acid can make phenylalanine ammonia-lyase in leaves The activity was significantly increased, so jasmonic acid, as a signal molecule, started the plant defense enzyme ...
