Description
Technical field
The present invention relates to corn planting technical fields, and in particular to a kind of amino acid liquid is fertile and its in corn planting
Using.
Background technology
During agricultural development, fertilizer plays a crucial role.Lead Chinese agriculture field the nineties in last century
" outstanding problem and suggestion that China's chemical fertilizer faces " report that the brainstrust of developing direction proposes promotes China's centering, micro
(Li Yong, Yu Guangwu, Li Xiaobing wait middle and trace element Fertilizer developments for the attention of element fertilizer, new-type fertilizer and environmental protection agricultural
Necessity and its Analysis on Prospect [J] chemical fertilizer industries, 2013,40 (4):1-3.).Hereafter, occur largely being directed to multi-component composite fertilizer
The research of effect.
In order to which the effect for allowing multiple element to be administered simultaneously is more than the effect applied respectively, middle and trace element must be just solved
Between antagonism problem and each element influenced to reduce the problem of plant absorption utilizes by soil pH.Since amino acid is not by soil
Earth pH and other ions influence, therefore are often used as the chelating agent (life of Shao Jianhua, Ma Xiaoxin Amino Acid Chelated Mineral Fertilizers of trace element
Production and the Guangdong application study progress [J] trace element science, 2000,7 (9):40-42；Wang Chen, Liu Chao, the spray of the blade faces the such as horse Jing
Apply influence [J] Chinese soil and fertilizer of the amino acid-zinc complexes to rice yield traits and zinc-iron alloy solution, 2017 (4):118-
123.)。
However, the amino acid being currently known kind of (Wagner I, Musso H.New Naturally up to more than 500
Occurring Amino Acids [J] .Angewandte Chemie International Edition, 2010,22 (11):
816-828.), the amino acid and used in fertilizer at present is mostly compound amino acid (including a variety of amino acid) rather than single ammonia
Base acid.Early in 1997, just studies have found that kilnitamin fertilizer efficiency be considered higher than etc. nitrogen quantity single amino acid (Xu Yu
Orchid, Liu Qingcheng Fertilizer Efficiency of Amino Acids research [J] amino acid and living resources, 1997 (2):1-6.).
Corn (Zea mays L.) has a decisive role in terms of world food and energy consumption.As corn
Important growing stage in growth and development process, grouting directly affect corn kernel dry-matter accumulation amount.In addition, bald tip of corn is existing
As the generally existing in Production of Large Fields, bald point phenomenon not only causes nutrient consumption, but also reduces seed quantity, the production to corn
Amount and quality cause extreme influence.Bald tip of corn after female fringe abortion of spikelets or little Hua inseminations mainly by failing normally to be in the milk
(woods, Rong Tingzhao, II, maize ear different parts little Hua of research, the seed of the green bald tip of corn of topaz are prayed by Tang caused by abortion seed
Differentiation and development period [J] Sichuan Agricultural University's journal, 1999,17 (2):162-166.).Some scholars by corn variety,
Macro-scales research bald tip of corn Producing reason (Zhang Wenzhong, Song Dianzhen, the chestnut such as soil fertility condition, planting density and climatic factor
Red-face role waits Reason Analysis on Barren Ear Tip of Maize [J] Exploitation of Agriculture in Heilongjiang science, 2007,2007 (6):20-22.), some research attempts
Establishing hormonal readiness, (woods, relationship [J] nuclear agricultural science reports of the clear bald tip of corn of Rong Ting and endogenous hormones, 2007,21 (4) are prayed by Tang:
366-368.), plant vasular beam (grind by the comparison of He Qiping, Dong Shuting, high Rong Qi different types corn variety Ear vascular bundles
Study carefully [J] Acta Agronomica Sinicas, 2007,33 (7):1187-1196.) being associated between bald tip of corn, some scholars from heredity and molecule
On the basis of dissect bald tip of corn phenomenon (ability source, Li Kai, Jiang Tao wait the Genetic Model Analysis and SSR marker of bald tip of corn characters
[J] Jilin Auto Industries, 2015,37 (1):6-13.).The research of forefathers is more to the preliminary of bald tip of corn reason
It probes into, fails to the practical operable method for solving the problems, such as this propose with universality, specific.
Invention content
The problems such as in order to solve such as bald tip of corn phenomenon, to improve the yield of corn.The present invention is carried in first aspect
A kind of amino acid liquid fertilizer is supplied, wherein the amino acid liquid fertilizer includes the water of amino acid and surplus, and the amino acid is essence
Propylhomoserin or glutamine.
Second aspect of the present invention provides a kind of corn planting method, wherein the method includes：It is sprayed to corn and includes
The liquid fertilizer of the amino acid of 0.5mM to 2.5mM, the amino acid are arginine and/or glutamine.
Third aspect present invention provides application of the amino acid in improving corn grouting effect, wherein the amino acid
For arginine and/or glutamine.
The present invention has the following technical effect that：(1) corncob phenotype improves, including grain plumpness improves, cob length
Increase, kernal number increases and bald sharp phenomenon mitigates；(2) mass of 1000 kernel increases, and increment is even as high as 22% or more in the kind having；

(3) section nitrogen potentiality=processing section nitrogen quantity * 100/CK handle amount of nitrogen；
Wherein：
CK indicates the nitrogen (urea) using 200 kg/ha；
LN indicates the nitrogen using 0 kg/ha；
Processing indicates the arginine or glutamine using 1.25mM；
Control indicates not apply the arginine of 1.25mM or glutamine but sprays equivalent (volume is equivalent to aminoacids solution
The volume of state fertilizer) water；
Then：
CK processing indicates the arginine or glutamy of nitrogen (urea) and application 1.25mM using 200 kg/ha
Amine；
LN processing indicates the arginine or glutamine of nitrogen (urea) and application 1.25mM using 0 kg/ha；
CK controls indicate the nitrogen (urea) using 200 kg/ha and spray to be equivalent to amino acid fertilizer (containing smart ammonia
Acid or glutamine) amount water；
CK processing amount of nitrogens include the N from nitrogen (urea) and the N from amino acid.
It can be seen that from section nitrogen potentiality correlation formula under conditions of reaching equal production volume, 2 kinds of amino acid processing are able to
The nitrogen of saving.The result for saving nitrogen potentiality is as shown in figure 19, it can be seen that applying arginine or glutamine in four differences
Nitrogenous fertilizer can be saved significantly in kind, can at least save 20% or more (LY99, arginine), it is highest to save nearly 90%
(87.6%, XY335, glutamine).In addition, section nitrogen potentiality are variant between different cultivars, and the section nitrogen of glutamine
Potentiality are above arginic section nitrogen potentiality in four different cultivars.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, it will be understood by those of ordinary skill in the art that：It still may be used
With technical scheme described in the above embodiments is modified or equivalent replacement of some of the technical features；
And these modifications or replacements, various embodiments of the present invention technical solution that it does not separate the essence of the corresponding technical solution spirit and
Range.
