Description
Technical field
The invention belongs to technical field of agricultural fertilizers, and in particular to a kind of Rice foliar fertilizer and preparation method thereof and promote water
The method of rice volume increase.
Background technique
Rice is one of big staple food in China three, is that China mostly important cereal crops and our people are favorite
One of staple food.China's Rice Cropping history is of long standing and well established, the unearthed charing rice of Zhejiang He Mudu, Hunan Luo Jiajiao, Jiahu, Henan Province
Paddy confirms that Chinese rice cultivates at least existing 7000 or more history.China is maximum Rice Production state in the world, face
Product occupies the second in the world, is only second to India, total output occupies the first in the world.Although China is to produce meter great Guo, it is also simultaneously
Big country is consumed, China consumes 1.3 hundred million tons of rice every year, and it is slightly remaining that domestic rice only realizes balance.Moreover, China human mortality base
Number is larger, and size of population estimation can all continue to keep increasing in 20 years.Persistently increase in the fixed still size of population of cultivated area
Under long environment, how to promote increasing production of rice, is following China within a very long time to ensure that China's rice is in liberal supply
Primary basic task.
German chemist Li Bixi is it is proposed that " law of minimum nourishment ", it is believed that crop yield is controlled by the smallest nutrient of quantity
System, the height of yield within certain limits with this nutrient number and change, so-called minimum nutrient just refers in soil most
That a kind of nutrient lacked, it is difficult continuing growing other nutritional ingredients if ignoring the presence of this limiting factor
To improve the yield of crop again.However, currently marketed major part rice fertilizer all includes various battalion needed for paddy growth
Element is supported, and dosage is substantially all the growth demand for being able to satisfy rice, still, the effective rate of utilization of these fertilizer is lower,
It is still not very obvious to the facilitation effect of increasing production of rice.
Summary of the invention
The main purpose of the present invention is to provide a kind of Rice foliar fertilizer, other goals of the invention of the invention are to provide institute

Embodiment quality described in the specification can be unit of weight well known to the field of medicaments such as μ g, mg, g, kg.
In order to which the effective rate of utilization for solving existing rice fertilizer is low, the limited technology of the facilitation effect of increasing production of rice is asked
Topic, the embodiment of the invention provides the method for a kind of Rice foliar fertilizer and preparation method thereof and promotion increasing production of rice, particular techniques
Scheme is as follows:
A kind of Rice foliar fertilizer, comprising: kelp enzymolysis liquid, protein hydrolysate, rare earth element, urea, potassium dihydrogen phosphate, micro
Element, sodium metasilicate, chelating agent and plant growth regulator；
By the kelp enzymolysis liquid be 15-30 parts by weight in terms of, the protein hydrolysate 10-20 parts by weight, the rare earth element
5-20 parts by weight, the urea 5-10 parts by weight, the dipotassium hydrogen phosphate 5-15 parts by weight, the microelement 1-5 parts by weight,
The sodium metasilicate 1-5 parts by weight, the chelating agent are 5-10 parts by weight, and the plant growth regulator is 0.5-2 parts by weight.
Rice foliar fertilizer provided by the invention, including kelp enzymolysis liquid, protein hydrolysate, the rare earth matched with specified weight
Element, urea, potassium dihydrogen phosphate, microelement, sodium metasilicate, chelating agent, plant growth regulator, each component synergistic effect will
It is applied to rice leaf, is greatly improved rice crop to the utilization rate of each nutrient, improves crop metabolism,
To promote paddy growth, increase the quantity of rice effective tillering, so that spike number increases, and makes Flag Leaves in Rice wider greener,
And then effectively facilitate increasing production of rice.
Specifically, kelp enzymolysis liquid is a kind of green organic composite type liquid fertilizer obtained using biological enzymolysis technology,
Rich in organic principles such as low molecule alginic acid, crude protein, carbohydrate, algal polysaccharide, mannitol, calcium, magnesium, iron, zinc, boron,
The auxin such as the minerals such as manganese and gibberellin, glycine betaine, cytokinin, phenols poly-compounds have significant pest-resistant
Expelling parasite and fungistatic effect.In embodiments of the present invention, it by the active constituent using kelp enzymolysis liquid, such as alginic acid, can drop
The surface tension of low water forms thin film in rice leaf, water-soluble substances is promoted to be easier through cauline leaf superficial cell
Film enters plant cell, so that crop be promoted to absorb remaining nutrient in fertilizer, improves the effective rate of utilization of fertilizer.
In some embodiments, the kelp enzymolysis liquid preparation method the following steps are included:
The water of dry kelp 1-2 parts by weight and described 13-17 times of weight of dry kelp is provided；
The pH of the water is adjusted to 8.5 or more, the dry kelp is added, and is heated at 40-50 DEG C until kelp is soft
Change, the enzyme preparation of 0.02-0.04 parts by weight is then added, reaction 8 hours or more, carries out destroy the enzyme treatment later, stands, in collection
Clear liquid.
In further embodiments, the enzyme preparation used when preparing the kelp enzymolysis liquid is selected as including pectase, fiber
The enzyme preparation of at least one of plain enzyme, protease is conducive to thoroughly enzymatic hydrolysis kelp, so that the active constituent of kelp enzymolysis liquid is more
It is easy to be absorbed by crops utilization.
Urea is a kind of high concentration nitrogenous fertilizer, is mainly used for nitrogen necessary to providing plant growth, rice is to nitrogen nutrition
It is very sensitive, therefore nitrogen is to determine one of most important factor of rice yield.In embodiments of the present invention, the urea is not only used
The nitrogen nutrition needed for providing plant growth is also used to soften blade face epidermal cell cuticula, to accelerate other nutrition of fertilizer
Element penetrates into crop body, and then promotes plant growth.Further, in embodiments of the present invention, the urea and institute are combined

This comparative example the difference from embodiment 1 is that: omit protein hydrolysate；Remaining place is substantially the same manner as Example 1, this
Place no longer repeats one by one.
Comparative example 4
This comparative example use mass percent concentration for 0.004% brassin lactones aqua.
Test case
This test case detects influence of the Rice foliar fertilizer of embodiment 1-2 and comparative example 1-4 offer to rice yield,
Specific test process and test result is as follows:
Using plot experiment, test variety: U.S. perfume (or spice) accounts for No. 2 or day excellent China accounts for, each cell 20m2, 5 processing groups are set,
It is respectively as follows: blank group, experimental group 1, experimental group 2, control group 1, control group 2, each processing group is repeated 3 times.Respectively at rice point
Tiller phase (transplanting latter week), panicle primordium dif ferentiation stage (when the young spike length degree in stem is 1cm or so) are to foliar applied fertilizer, blank pair
Clear water is sprayed according to group, experimental group 1 sprays the Rice foliar fertilizer of embodiment 1, and experimental group 2 sprays the Rice foliar fertilizer of embodiment 2, right
The Rice foliar fertilizer of comparative example 1 is sprayed according to group 1, control group 2 sprays the Rice foliar fertilizer of comparative example 2, and control group 3 sprays comparative example
3 Rice foliar fertilizer, control group 4 spray comparative example 4 brassin lactones aqua other using identical management, to rice maturation
Afterwards, its yield is measured respectively, and testing result is as shown in Table 1 and Table 2.
Table 1
Note: test variety is that U.S. perfume (or spice) accounts for No. 2
Table 2
Note: test variety is that the excellent China in day accounts for
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
