Description
Technical field
The invention belongs to Rice Cropping technical fields, are related to the fertilizing method of rice, specially a kind of rice in saline-alkali field
Fertilizing method.
Background technique
Currently, for global saline alkali land area up to 9.5 hundred million hectares, saline-alkali soil is the general designation of solonchak and alkaline earth, is general in the world
All over existing land resource, since it contains the excess salt and alkali component such as chloride, sulfate, heavy carbonate, Yi Yinqi soil object
Reason, chemical property change, and most of crop growth environment is caused to degenerate, grow by different degrees of inhibition.Salt-soda soil
Soil is there are pH value height, salt content height, and alkaline land soil is barren, and rich water utilization rate is not high.Coastal alkaline land soil silt content
Height, the content of organic matter is not high, and soil aggregate structure is poor, and soil rich water buffer capacity is not strong.
The rice in saline-alkali field exploitation plantation of " to wash salt, with hydraulic pressure alkali, with rice water log control " in recent years, successfully develop
Technology, so that salt-soda soil be made to obtain effective exploitation utilization.But the edaphic condition and environmental condition special due to salt-soda soil, change
Fertile dosage is excessive, fertilizer application frequency is more, and utilization rate of fertilizer is low.Therefore the development of fertilizer dedicated to alkaline land material is always scientific worker's
Research emphasis.Currently, existing fertilizer dedicated to alkaline land is single, the indissoluble in improving alkaline land soil structure and dissolution alkaline land soil
Property metallic compound in terms of it is ineffective, the gas permeability of soil can not be effectively improved, N P and K and micro- in water-retaining property and soil
Secondary element utilization rate causes alkaline land improving ineffective.
Summary of the invention
In view of the above problems, purpose is intended to provide a kind of rice in saline-alkali field fertilizing method to the present invention, and this method reaches
To nitrogen application number and dosage is reduced, fertilizer utilization efficiency and production efficiency are improved, improves rice quality.
In order to achieve the above technical purposes, the present invention is realized especially by following technical scheme:
A kind of fertilizing method of rice in saline-alkali field, including application base manure, fetilizer for tillering and ear manuer:
The 50%~60% of the total amount of application of nitrogen fertilizer of nitrogenous fertilizer Zhan in the base manure, the total nitrogenous fertilizer of nitrogenous fertilizer Zhan in the tillering fertilizer
The 20%~30% of amount of application, the 10%-20% of the total amount of application of nitrogen fertilizer of nitrogenous fertilizer Zhan in the ear manuer；
The nitrogen fertilizer slow-releasing phase is respectively 100d, 50d and 50d in the base manure, fetilizer for tillering and ear manuer；
The determination of total nitrogen fertilizer amount: 500 kilograms of rice of per mu yield 12-14 kilograms of purity nitrogen per acre.
Further, the content of N P and K is respectively 22%:8%:0% in the base manure；Nitrogen in the tillering fertilizer
The content of phosphorus potassium is respectively 22%:8%:0%, and the content of N P and K is respectively 22%:0%:5% in the ear manuer.
Further, the basal fertilizer applying method is drained after water in field becomes clear, then, is applied after the 1-2 rotary tillage desalinization of soil by flooding or leaching
With base manure, rakes filling shallow water, prepare rice transplanting or live streaming.
Further, the step of applying of the tillering fertilizer: tillering fertilizer is using primary or secondary application, and fertilising exists for the first time
1 week after record, second of fertilising is 7-10 days after first time applies fertilizer, and for the first time and the quantity of second of fertilising accounts for 50% respectively.
Preferably, breeding time longer kind, using secondary fertilising.Tillering fertilizer application before paddy field moisture is fallen naturally it is dry,
It applies fertilizer, then irrigates when field face is wet, reach 3-5cm water layer, will be seeped into topsoil under the fertilizer companion moisture of thawing.
Further, the step of applying of the ear manuer: the application when four leaves start elongation falls paddy field moisture naturally
It is dry, it applies fertilizer when field face is wet, then irrigate, reaches 3-5cm water layer, topsoil will be seeped under the fertilizer companion moisture of thawing.
The invention has the benefit that
Implementation method of the present invention is reasonably combined by organic fertilizer and chemical fertilizer in rice different growing, makes to apply fertilizer scientific and reasonable,
And fertilizer is saved, it is remarkably improved yield and quality of rice；Base manure is that soil lays in nutrient, provides nutrient for rice after transplanting；
Tillering fertilizer promotes rice tillering, plays the role of increasing fringe；The main purpose of ear manuer is to improve setting percentage, it is ensured that full maturity increases
Add mass of 1000 kernel.
Specific embodiment
Below in conjunction with specific embodiment of the present invention, technical solution of the present invention is clearly and completely described, is shown
So, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the reality in the present invention
Example is applied, every other embodiment obtained by those of ordinary skill in the art without making creative efforts all belongs to
In the scope of protection of the invention.
A kind of fertilizing method of rice in saline-alkali field, including application base manure, fetilizer for tillering and ear manuer:
