Abstract
The invention provides a controlled-release fertilizer for a germination stage of peanuts. The fertilizer is characterized in that slow release gum is taken as a carrier and wraps the outermost layer of fertilizer grains; the slow release gum is prepared from the following raw materials in parts by weight: 1.2 parts of pentaerythritol stearate, 0.3 part of tetraethylenepentamine, 1.5 parts of nano calcium oxide, 2.3 parts of rare earth and 35 parts of liquid abietic resin. The slow release gum is formed by means of mixing the raw materials, heating to 85 DEG C, keeping temperature in a water bath, and continuously stirring for 15 or more than 15 minutes. The controlled-release fertilizer disclosed by the invention has the advantages that the fertilizer can be controllably released in stages for different growth stages of a crop, controlled-release films in different stages are taken as a controlled-release basis, and holes are formed in the controlled-release films through degradation, so that the fertilizer is released slowly, and different slow-releasing periods and different time required for forming the holes through degradation are formed by means of designing different components in the controlled-release films.

Fertiliser granulates be manured into soil in after, first outermost stage compound fertilizer of emerging discharges, to Semen arachidis hypogaeae
Stage of emerging provides nutrient, and stage compound fertilizer of emerging, with slow release glue as carrier, reaches the slow release of first stage
Purpose；After first stage terminates, outer layer release-controlled film starts degraded, and after 4-6 days, outer layer release-controlled film is degraded out
Existing hole, growth stage compound fertilizer passes through outer layer release-controlled film slow release, and effective controlled release period is 25-35 days, should
Stage is second stage slow release, and after second stage slow release terminates, middle level release-controlled film starts degraded, and the time is
After 1-2 days, there is hole in middle level controlled release membrane degradation, and the flowering phase, compound fertilizer was by middle level release-controlled film slow release,
Effectively controlled release period is 4-7 days, and this stage is phase III slow release；After phase III slow release terminates, internal layer
Release-controlled film starts degraded, and 2.5-3.5 days, hole occurred in the degraded of internal layer release-controlled film, and the result stage, compound fertilizer led to
Crossing internal layer release-controlled film slow release, effective controlled release period is 8-15 days, and this stage is fourth stage slow release.
The invention has the beneficial effects as follows:
The present invention can realize release and release control fertilizer stage by stage for crop different growth phases, with different phase
Release-controlled film is controlled release basis, makes release-controlled film hole occur by degraded, so that fertilizer slow release, by control
Release the design that component in film is different, reach different slow release cycle and degraded occurs needed for hole different time
Between.
