preparation example Construction

[0051] The present invention also provides a preparation method of the controlled-release formula fertilizer, which can be obtained by putting all the raw materials of the controlled-release formula fertilizer of the present invention into a blender, stirring and fully mixing. The stirring time is preferably 5-10 minutes, so as to prevent the influence of stirring heat on the fertilizer efficiency of each raw material.

[0052] The particle size of each of the above-mentioned raw materials is preferably within the range of 2-4 mm, so as to improve the mixing efficiency and ensure that the fertilizer supply of the obtained controlled-release formula fertilizer is in harmony with the law of plant fertilizer demand.

[0053] The invention also provides the application of a controlled-release formula fertilizer, which is applied once as a base fertilizer when sowing. Preferably, no top dressing is necessary.

[0054] The controlled-release formula fertilizer of the present invent...

Abstract

The invention provides a controlled-release formula fertilizer, a preparation method and application thereof. The controlled-release formula fertilizer comprises more than two controlled-release fertilizers with different release periods and at least one quick-acting chemical fertilizer. Supply of the fertilizer is coordinated with the fertilizer requirement rule of plants.

Description

technical field [0001] The invention relates to a slow and controlled-release fertilizer, a preparation method and application thereof, in particular to a controlled-release formula fertilizer in which the fertilizer supply and plant fertilizer demand are in harmony, the preparation method and the application thereof. Background technique [0002] The main defect of quick-acting chemical fertilizers is that the nutrient supply pattern is inconsistent with the nutrient absorption of crops (including vegetables), and cannot meet the high-intensity demand for nutrients in the rapid biomass accumulation stage of crops. Reasonable) leads to relatively low fertilizer utilization efficiency of current plants (such as cabbage vegetables), and increases the risk of environmental pollution. [0003] Coated controlled-release fertilizer is a new type of fertilizer specially developed for the nutrient supply defects of ordinary quick-acting chemical fertilizers. For example, the control...
