Fertilizer special for relieving successive cropping obstacles of melons

Abstract

The invention discloses a fertilizer special for relieving successive cropping obstacles of melons. The fertilizer is prepared from, by weight, 33-35 parts of activated sludge, 18-20 parts of pulverized fuel ash, 1.3-1.4 parts of Carbomer resin, 2-3 parts of potassium iodide, 6-7 parts of ammonium sulfate, 0.5-0.7 part of sodium citrate, 2-3 parts of EM microbial agent, 1.3-1.4 parts of sucrose enzyme preparation, 1.5-1.8 parts of selenomethionine, 37-43 parts of cyanobacteria, 32-35 parts of corn straws, 2-3 parts of anhydrous calcium chloride, a moderate amount of sodium carbonate, a moderate amount of 5% sulfuric acid solution and a moderate amount of water. A large amount of organic raw materials is added to the fertilizer for soil microbial structure imbalance caused by successive cropping of melons, a variety of beneficial bacteria are added for supplementing, the transition from 'bacterium type' to 'fungus type' of soil microbes is relieved, meanwhile beneficial bacterium groups are formed, the allelochemicals produced in successive cropping are degraded, the amount of soil enzymes is increased, the soil enzyme activity is improved, and further the economic benefits of continuous cropping are ensured.

Description

technical field

[0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for alleviating obstacles to continuous cropping of melons. Background technique

[0002] With the deepening of fertilizer application research, fertilizers have developed from the initial single type fertilizer to the current multi-type compound organic fertilizer. However, there are relatively few researches on specific planting and special-purpose fertilizers for melons. In addition, the melon fertilizers currently used in the market mainly have shortcomings such as low content of macroelements, incomplete content of medium and microelements, lack of bio-organic substances, inability to provide effective solutions to common difficulties and problems in melon cultivation, and short validity period of fertilizer effect. .
