Description
Technical field
The present invention relates to a kind of release and release control fertilizers, more particularly, to a kind of dedicated release-controlled with the millet broadcast suitable for seed manure
Fertilizer.
Background technique
Background of related of the invention is illustrated below, but these explanations might not constitute it is of the invention existing
Technology.
Millet has had more than 8700 years cultivation histories so far, has been cultivation most ancient in the world originating from China
One of crop.About 2,000,000 hm of China's millet planting area2, it is concentrated mainly on the North China, northeast, northwest drought and half-dried in the north
Nonirrigated farmland area.The features such as millet is full of nutrition with its, drought resisting is barren-resistant, wide adaptability, increasingly attracts people's attention, and is in recent years
Come the chief crop for the coarse cereals heat risen.
In recent years, empiric fertilization leaned on substantially on fertilizer application in peasant household during millet planting, and there are many problems, examples
Such as fertilization structure is unreasonable, fertilizing method is improper.Peasant's randomness when fertilizer is selected is stronger, and when fertilising lacks scientific basis
And theoretical direction, fertilizer utilization efficiency are low.The inclined nitrogen fertilizer application of traditional habit and excessive application for a long time, cause millet to absorb
More nitrogens, disease-resistant, capacity for the resistance to lodging reduce, low quality.Simultaneously extra nitrogen volatilized in the form of ammonia or nitrate nitrogen or with
Water is seeped into deep subsoil, pollutes environment, and utilization rate reduces, waste is serious, and farming returns of investment are bad.Phosphorus potash fertilizer and micro- fertilizer are used
Amount is insufficient, leads to soil nutrient disequilibrium, and nutritional deficiency disease occurs in crop, equally influence yield and quality.Determine that millet fertilizer is used
Amount and Application Ratio, reasonable balance fertilising, improving utilization rate of fertilizer is the root for improving millet yield, improving soil property, reducing pollution
This measure.
With the development of fertilizer industry, Controlled Release Fertilizer increasingly caused by everybody concern, domestic release and release control fertilizer industry grinds
Study carefully in progress, China has been developed that a variety of release and release control fertilizers, and advantage of lower cost, generally the 1.2~1.3 of common fertilizer times.
Portioned product is mainly used for the crops such as rice, cotton, fruit tree at present, and achieves preferable effect.Some researches show that with length
Effect ammonium bicarbonate carries out overfertilization effect test on the crops such as rice, wheat, cotton, sugarcane, tealeaves, rubber and kelp, the results showed that,
The fertilizer efficiency of sandy soil, long-term efficiency bicarbonate ammonium is higher than normal ammonium bicarbonate, and can reduce fertilizer application frequency, and effect of increasing production is obvious.With controlled release
The reduction of fertilizer production cost and the increase of yield, extensive use of the release and release control fertilizer in all kinds of crop productions are chemical fertilizer hairs
The inevitable direction of exhibition also will increasingly be paid close attention to by everybody in millet application special-purpose control-release fertilizer.
Controlled Release Fertilizer can slow down or control the release of nutrient, and fertilizer efficiency period is long and stablizes, and be able to satisfy millet in entire breeding time pair
The demand of nutrient；Reduce the loss such as elution of fertilizer；Dose and number can be reduced, labour is saved, improves the utilization of fertilizer
Efficiency improves the yield and quality, and saves agriculture production cost.
Summary of the invention
For the above-mentioned problems in the prior art, the object of the present invention is to provide a kind of suitable for the special of Growth of Millet
With Controlled Release Fertilizer, it fully takes into account the nutrient requirement characteristics of Growth of Millet phase, by N P and K and middle microelement suitably to compare
Example cooperation, and suitable dicyandiamide, humic acid is added.The needs that not only can satisfy millet the previous growth, meet tiller
The nutrient demand of phase, jointing stage, heading stage, maturity period reduce fertilizer loss caused by multiple top dressing, improve fertilizer efficiency, addition
The iron zinc nutrition that millet seed can be improved in iron fertilizer, zinc fertilizer is horizontal, and soil productivity and millet product can be improved in the humic acid of addition
The dicyandiamide of matter, addition can also improve fertilizer effectiveness.

Plot area: long 30 meters wide 10 meters 300 square metres total.
Planting Row Distance: line-spacing 40cm.
Sowing date: on June 24th, 2015
Test result
(1) harvest time physiological index determining result
September 28 days, in millet harvest time, investigate each processing millet plant height and cauline leaf etc. is tested, each cell with
Machine is investigated 12 plants and is averaged, measurement result such as following table.
Measurement result shows: 1 (special-purpose control-release fertilizer) stem thickness of processing, leaf is long, leaf width is maximum；Handle 2 (traditional fertilization) strains
High highest, and stem thickness, leaf are long, leaf width is less than processing 1；It is minimum to handle 3 (blank) indices.
(2) yield component and yield result
September 29 days, Controlled Release Fertilizer test concentrate and surveys production.12 plants of each cell random searching is averaged, and investigates paddy
Sub- fringe is thick, spike length and spike weight Isoquant constituent element index；Each cell randomly selects 3 sample prescriptions, each sample area
30m2, each sample prescription harvest millet seed weighing, which is surveyed, to be produced, and is produced average value with 3 sample prescriptions surveys and is converted cell production.
Survey produce the result shows that, processing 1 (special-purpose control-release fertilizer) yield forming indices be above processing 2 (traditional fertilization) and
3 (blank) are handled, 1 yield of processing is respectively than high 14.7 kgs/acre and 76.9 kgs/acre of processing 2 and processing 3；(the tradition of processing 2
Fertilising) yield is 3 62.2 kgs/acre higher than handling.
Although referring to illustrative embodiments, invention has been described, but it is to be understood that the present invention does not limit to
The specific embodiment that Yu Wenzhong is described in detail and shows, without departing from claims limited range, this
Field technical staff can make various changes to the illustrative embodiments.
