Problems solved by technology

However, in the exogenous substances that improve the drought resistance of wheat and corn, there is a lack of polyamine components, so the effect of the existing external spraying technology has certain limitations, and the improvement of the drought resistance and yield of wheat and corn is limited. limits

Embodiment 1

[0012] A polyamine complex agent for enhancing the drought resistance of wheat and corn, which consists of the following components in parts by weight: 7-280 parts of putrescine, 0.4-10 parts of spermidine, 0.8-16 parts of spermine, and 1 part of succinic acid -15 parts, chitin 6-150 parts.

[0013] The components are weighed in parts by weight, and the weighed components are dissolved in 50,000-150,000 parts of water to prepare the polyamine complex agent.

[0014] One or at least two stages of wheat and corn development are treated with polyamine compound agents, including seed dressing or soaking of wheat and corn seeds, or applying polyamine compound agents at the seedling stage of wheat and corn, or applying polyamine compound agents at the wheat and corn seedling stage. Apply the polyamine compound agent at the heading stage, or apply the polyamine compound agent to the wheat and corn seeds and the seedling stage sequentially, or apply the polyamine compound agent to the...

Embodiment 2

[0016] A polyamine complex agent for enhancing the drought resistance of wheat and corn is composed of the following components in parts by weight: 7g of putrescine, 0.4g of spermidine, 0.8g of spermine, 1g of succinic acid and 6g of chitin.

[0017] Each component is weighed in parts by weight, and the weighed components are dissolved in 50L of water to prepare the polyamine complex agent. The polyamine complex agent is applied sequentially to wheat and corn seeds and seedling stage.

Embodiment 3

[0019] A polyamine complex agent for enhancing the drought resistance of wheat and corn is composed of the following components in parts by weight: 40g of putrescine, 2g of spermidine, 4g of spermine, 4g of succinic acid and 30g of chitin.

[0020] Each component is weighed in parts by weight, and each component weighed is dissolved in 75L of water to prepare the polyamine complex agent. The polyamine complex agent is applied sequentially to wheat and corn seeds and heading stage.

Abstract

The invention provides a polyamine composite agent enhancing wheat and corn drought resistance. The composite agent is composed of the following components, by weight: 7-280 parts of putrescine, 0.4-10 parts of spermidine, 0.8-16 parts of spermine, 1-15 parts of succinic acid, and 6-150 parts of chitin. According to the invention, the weighed components are dissolved into 50000-150000 parts of water, such that the polyamine composite agent is obtained. Compared with prior arts, formerly commonly used spraying agent components are broken through. While the drought resistance of wheat and corn is improved, polyamine can be absorbed by plants according to agriculturally applied concentrations, such that no residue is left in soil. Even the polyamine absorbed by plants enters human and livestock bodies, the concentrations are greatly lower than those synthesized by human and livestock. The composite agent is harmless to human and livestock, and has a relatively low cost.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a polyamine compound agent for enhancing the drought resistance of wheat and corn. Background technique [0002] During the entire growth period of crops, they are often plagued by drought. In response to such natural disasters, researchers often start with methods such as cultivation techniques, chemical regulation, breeding of new drought-resistant varieties and biotechnology to improve the drought resistance of crops. In terms of chemical regulation, in recent years, scholars have used laboratory research methods to try to use various plant growth regulators to improve crop drought resistance; in production practice, they have also been widely used, such as: one spray three anti-pesticides The formulations of Yemianbao and Yemianbao all contain different concentrations of agricultural abscisic acid, paclobutrazol and other plant growth regulating ...
