Abstract
The invention provides a slow release fertilizer for peanuts. The fertilizer is a granular fertilizer; fertilizer granules comprise three slow release films, namely, the outer-layer slow release film, the middle-layer slow release film and the inner-layer slow release film, wherein the outer side of the outer-layer slow release film is wrapped with seedling-emergence-stage compound fertilizer, the space between the outer-layer slow release film and the middle-layer slow release film is filled with growth-stage compound fertilizer, the space between the middle-layer slow release film and the inner-layer slow release film is filled with flowering-stage compound fertilizer, and fruiting-stage compound fertilizer is wrapped in the inner-layer slow release film. Stage-by-stage slow release of the fertilizer can be achieved for different growth stages of crops, with the slow release films for different stages as the slow release basis, pores are formed in the slow release films through degradation, and thus the fertilizer can be slowly released; through the design of different components in the slow release films, different slow release cycles and different times needed for pore formation in degradation are achieved.
Description
Technical field
The present invention relates to controlled-release compound fertilizer field, particularly relate to one and cultivate peanut Controlled Release Fertilizer.
Background technology
Controlled-release compound fertilizer refers to slow down or control the new-type fertilizer of nutrient releasing speed, also becomes slow-release fertilizer,
It is roughly divided into sulphur coating (fertile bag fertilizer), resin coating, urease inhibitors etc..Existing Controlled Release Fertilizer can only
Accomplish a sustained release cycle, it is impossible to according to the different phase of plant growth, control by stages release fertilizer.
Summary of the invention
It is an object of the invention to provide one to cultivate peanut Controlled Release Fertilizer, to solve above-mentioned technical problem.
The technical problem to be solved realizes by the following technical solutions:
One cultivates peanut Controlled Release Fertilizer, it is characterised in that: fertilizer is granular fertilizer, and fertiliser granulates includes three layers of controlled release
Film, respectively outer layer release-controlled film, middle level release-controlled film and internal layer release-controlled film, wrap outside described outer layer release-controlled film
It is wrapped with stage composite fertilizer of emerging, is filled with growth phase between described outer layer release-controlled film and middle level release-controlled film multiple
Hefei, is filled with flowering phase composite fertilizer, internal layer controlled release between described middle level release-controlled film and internal layer release-controlled film
Film internal package has result stage composite fertilizer；
It is 4-6 days that described outer layer release-controlled film is degraded into the time of penetrating film, and effective controlled release period is 25-35 days,
Outer layer release-controlled film is made up of the raw material of following weight portion: titanium dioxide 2 parts, peat soil 1.5 parts, clay 2 parts,
Delustring micro mist wax 1.2 parts, erucyl amide 5 parts, pentaerythritol stearate 0.3 part, polyethylene are 105 parts；
Preparation method is: above-mentioned each raw material mixes, and through twin screw extruder extruding pelletization, then is blow molded through film
Machine blow molding, can obtain outer layer release-controlled film；
Described middle level controlled release membrane degradation becomes the time of penetrating film to be 1-2 days, and effective controlled release period is 4-7 days,
Middle level release-controlled film is made up of the raw material of following weight portion: nano-silica powder 1.6 parts, turfy soil 1.2 parts,
Paris white 2 parts, delustring micro mist wax 1.2 parts, erucyl amide 5 parts, pentaerythritol stearate 0.3 part,
Polyethylene is 105 parts；Preparation method is: above-mentioned each raw material mixes, through twin screw extruder extruding pelletization,
Again through film blow molding machine blow molding, middle level release-controlled film can be obtained；
It is 2.5-3.5 days that described internal layer release-controlled film is degraded into the time of penetrating film, and effective controlled release period is 8-15
My god, internal layer release-controlled film is made up of the raw material of following weight portion: 1.2 parts of aluminum oxide, fertile soil 2.2 parts, carbon
Acid calcium powder 2 parts, delustring micro mist wax 1.2 parts, erucyl amide 4 parts, pentaerythritol stearate 0.3 part, poly-
Ethene is 115 parts；Preparation method is: above-mentioned each raw material mixes, through twin screw extruder extruding pelletization,
Again through film blow molding machine blow molding, internal layer release-controlled film can be obtained.
Described stage composite fertilizer of emerging is to be wrapped in the outermost layer of fertiliser granulates for carrier being sustained glue, described
Sustained release glue is made up of the raw material of following weight portion:
Pentaerythritol stearate 1.2 parts, TEPA 0.3 part, nano calcium oxide 1.5 parts, rare earth 2.3
Part, liquid rosin resin 35 parts；
Above-mentioned each raw material mixes, and is heated to 85 DEG C, and continuously stirred more than the 15min of water bath heat preservation to obtain final product.
This Controlled Release Fertilizer be manured into soil in after, first outermost stage composite fertilizer of emerging discharges, to peanut
Stage of emerging provides nutrient, and stage composite fertilizer of emerging, with sustained release glue as carrier, reaches the sustained 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 phase composite fertilizer is sustained by outer layer release-controlled film, and effective controlled release period is 25-35 days, should
Stage is second stage sustained release, and after second stage sustained 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, composite fertilizer was sustained by middle level release-controlled film,
Effectively controlled release period is 4-7 days, and this stage is phase III sustained release；After phase III sustained 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, composite fertilizer led to
Crossing internal layer release-controlled film sustained release, effective controlled release period is 8-15 days, and this stage is fourth stage sustained 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 sustained release cycle and degraded occurs needed for hole different time
Between.
