Embodiment

[0041] The technical solutions of the present invention will be illustrated below in the form of examples, but the protection scope of the present invention is not limited to these examples.

[0042] 1. Materials and methods

[0043] Location: Experimental Station of China Agricultural University, Shangzhuang, Beijing.

[0044] Corn strains: Xianyu 335 (XY335), Zhengdan 958 (ZD958), Liangyu 99 (LY99) and Denghai 605 (DH605). These maize varieties were purchased from Beijing Si Nong Seed Industry Co., Ltd.

[0045] 1.1 Under the conditions of normal nitrogen supply (CK, 200 kg / ha of nitrogen (urea)) and low nitrogen (LN, 0 kg / ha of nitrogen), the following treatments are carried out:

[0046] (1) Treatment 1 (T1): Spray water;

[0047] (2) Treatment 2 (T2): spray 1.25mM arginine;

[0048] (3) Treatment 3 (T3): 1.25 mM glutamine was sprayed.

[0049] Spraying was carried out in the following stages: (a) stage 1 (ST1): the 6th maize leaf was fully expanded (maize jointing st...

Abstract

The invention relates to an amino acid liquid fertilizer and application thereof in corn planting, and particularly provides an amino acid liquid fertilizer. The amino acid liquid fertilizer comprisesamino acid and the balance of water, and the amino acid is arginine or glutamine. The invention further provides a corn planting method. The method comprises the steps of spraying the amino acid liquid fertilizer for corns. The invention further provides application of the amino acid which is the arginine or the glutamine in the improvement of a corn filling effect. The amino acid liquid fertilizer is simple in formula, convenient to use and remarkable in fertilizer efficiency, is used for corn planting, and can comprehensively improve the corn filling effect, particularly, corncob phenotypesare improved remarkably (including improvement of grain plumpness, increasing of lengths of spike-stalks, increasing of the number of grains and relieving of bare tips), and thousand seed weight, kernels per spike, grain weight per spike, grain type carotene concentration and the like are improved.

Description

technical field [0001] The invention relates to the technical field of corn planting, in particular to an amino acid liquid fertilizer and its application in corn planting. Background technique [0002] Fertilizers play a vital role in the development of agriculture. In the 1990s, experts leading the development direction of China's agricultural field put forward the report "Prominent Problems and Suggestions Faced by my country's Chemical Fertilizers", which promoted my country's emphasis on medium and trace element fertilizers, new fertilizers and environmental protection agriculture (Li Yong, Yu Guangwu, Li Xiaobing, et al. Necessity and prospect analysis of the development of medium and trace element fertilizers [J]. Fertilizer Industry, 2013, 40(4):1-3.). Since then, there have been a large number of studies on the effects of multi-component compound fertilizers. [0003] In order to make the effect of simultaneous application of multiple elements greater than the effe...
