Abstract
The invention relates to an improved controlled-release fertilizer which is prepared from the following components in parts by weight: 3-8 parts of monoammonium phosphate, 6-10 parts of ferrous sulfate, 9-15 parts of organic fertilizer, 2-8 parts of calcium superphosphate, 3-9 parts of zeolite, 8-14 parts of grass carbon, 4-6 parts of ammonium molybdate, 3-5 parts of calcium nitrate, 3-6 parts of clay, 5-10 parts of alfalfa, 5-8 parts of plant lactobacillus, 2-5 parts of EDTA chelated zinc and 2-8 parts of sodium selenite. The controlled-release fertilizer can provide nutrient substances for crops for a long time, has long acting time, and can provide nutrients according to crop demands.
Description
Technical field
The present invention relates to a kind of slow-release or control-release fertilizer of improvement.
Background technology
Sustained-controll-release fertiliser refers to that fertilizer nutrient rate of release is slow in a broad sense, and release period is longer, can meet the fertilizer of plant growth need in the whole vegetative period of crop.But concerning slow-release fertilizer and Controlled Release Fertilizer, there is again its definition different separately in the narrow sense.Slow-release fertilizer is also known as controlled availability fertilizer, and mainly finger changes the speed of plant available nutrient into than common fertilizer fertilizer slowly after being manured into soil.Its rate of release, mode and time length can not control well, and the impact by fertilization mode and envrionment conditions is larger.Controlled Release Fertilizer release principle is that the nutrient in fertilizer is from the process of solid state into liquid state, the speed of its release and the rule of Crop nutrient match, time such Crop nutrient is many, just release is many, what just discharge time few lacks, and improves the utilization ratio of fertilizer greatly, so Controlled Release Fertilizer is more high in technological content than common fertilizer, there is the effect of Intelligent controlled release, so be also its intelligent fertilizer.
Summary of the invention
For the deficiencies in the prior art, the technical problem to be solved in the present invention is, provides a kind of slow-release or control-release fertilizer, can provide nutritive substance for a long time, long action time to crop, can need to provide nutrition according to crop.
For solving the deficiencies in the prior art, technical scheme of the present invention is, a kind of slow-release or control-release fertilizer of improvement, and it is made up of following weight part:
Monoammonium phosphate 3-8 part, ferrous sulfate 6-10 part, fertilizer 9-15 part, calcium superphosphate 2-8 part, zeolite 3-9 part, peat composed of rotten mosses 8-14 part, ammonium molybdate 4-6 part, nitrocalcite 3-5 part, clay 3-6 part, Alfalfa 5-10 part, plant lactobacillus 5-8 part, EDTA chelated zinc 2-5 part, Sodium Selenite 2-8 part.
The invention has the beneficial effects as follows, slow-release or control-release fertilizer of the present invention, nutritive substance can be provided to crop for a long time, long action time, can need to provide nutrition according to crop.
