Description
Technical field
The present invention relates to new slow release fertilizer technical field, more particularly to a kind of wheat special slow release bulk blended fertilizer and its
Preparation method.
Background technology
At present, conventional fertilizers industry period at a low ebb, new-type fertilizer is increasingly subject to pay attention to, and as numerous fertilizer enterprises
Tackle " sharp weapon " of market quagmire.China's new-type fertilizer is roughly divided into Slow/Controlled Release Fertilizers, bio-feritlizer, multifunctional fertilizers, synergy class
The major class of fertilizer etc. four.Slowly/controlled releasing fertilizer can be divided into two classes according to nutrients release principle：One class is the course of dissolution for controlling nutrient,
So as to control nutrient to the dissolution rate in soil, nutrient is absorbed beneficial to crop, such as chemical synthesis sustained-controll-release fertiliser,
Physics encapsulates fertilizer；One class is the conversion rate for controlling fertilizer nutrient in soil, such as addition urease inhibitor, nitrification inhibitor
Fertilizer.
In recent years, as the popularization of the raising, no-tillage cultivation new agricultural technology and high-yield variety of wheat purchasing price should
With District of Shanghai yield of wheat has raising by a relatively large margin, and plantation economic benefit is significantly improved, and wheat planting area is also returned year by year
Rise., still using traditional fertilization mode that spreads fertilizer over the fields, unevenness of application, depression collected manure are excessive, so as to cause for current Shanghai Wheat Production
Nutrient loss, environmental pollution.The conventional fertilizer of wheat planting is mostly the kind that fertilizer efficiency period is short, plant recovery of nutrient is relatively low, is applied partially
Nitrogen content fertilizer high, to ignore the phenomenons such as supplement to phosphorus potash fertilizer more universal.Research shows that nutrient is single not only to influence small
The yield and quality of wheat, also easily causes the remaining green when it is due to become yellow and ripe later stage lodging of wheat early stage.Additionally, being commonly used during the wheat planting of Shanghai
Composite fertilizer and special fertilizer be mostly that specific aim is poor based on universal formula, utilization rate of fertilizer is low, do not take into full account difference
The nutrient supply feature and the nutrient requirement characteristics of wheat of soil types, easily cause base manure excessively apply and nitrogen fertilizer amount it is higher,
