Embodiment 1

[0024] The coating agent, calculated by weight percentage, comprises 94% of polyaspartic acid, 4% of sorbifolia fruit shell powder, and 2% of ethylenediamine crosslinking agent.

[0025] preparation:

[0026] (1) According to the above ratio, add ethylenediamine crosslinking agent to polyaspartic acid to increase the viscosity of the mixture; (2) Grind Xantho radix sorbifolia powder on an ultrafine pulverizer until the fineness reaches 150 mesh Above; (3) the high-viscosity polyaspartic acid prepared in step (1) is evenly coated on the outside of corn seeds, and then the shell powder obtained in step (2) is wrapped, and dried under natural ventilation conditions to obtain Corn coated seeds.

[0027] Said, the weight ratio between the seed and the polyaspartic acid is 1:0.8.

Embodiment 2

[0029] The coating agent comprises 90% of polyaspartic acid, 6% of sorbifolia husk powder and 4% of ethylenediamine crosslinking agent by weight percentage.

[0030] preparation:

[0031] (1) According to the above ratio, add ethylenediamine crosslinking agent to polyaspartic acid to increase the viscosity of the mixture; (2) Grind Xantho radix radix sorbifolium powder on an ultrafine pulverizer until the fineness reaches 50 mesh Above; (3) the high-viscosity polyaspartic acid prepared in step (1) is evenly coated on the outside of corn seeds, and then the shell powder obtained in step (2) is wrapped, and dried under natural ventilation conditions to obtain Corn coated seeds.

[0032] Said, the ratio of parts by weight between seeds and polyaspartic acid is 1:1.

Abstract

The invention relates to the field of applications of biomass materials to crop planting, in particular to a corn seed coating agent with root strengthening, seedling strengthening and water retention functions and a preparation method of the corn seed coating agent. The coating agent comprises polyaspartic acid, a crosslinking agent and xanthoceras sorbifolia bunge shell flour, wherein the weight ratio of polyaspartic acid to the crosslinking agent is 200: (1-6), and the proportion of xanthoceras sorbifolia bunge shell flour to polyaspartic acid is 1: (15-45). By means of the obtained corn seed coating agent, corn seeds planted in the soil under the arid and semiarid climate conditions can obtain more sufficient water and nutrients, the seed germination rate is guaranteed, growth at the corn seedling stage is promoted, and stress tolerance of corn is increased. With adoption of the method, the cost is low, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of applying biomass materials to crops, in particular to a corn seed coating agent with functions of strong roots, strong seedlings and water retention and a preparation method thereof. Background technique [0002] Corn is the second largest crop in the world and the most important source of food and feed. my country is the second largest corn producer in the world, with an annual output of more than 67.5 million tons of corn. Corn is one of the main food crops with the largest demand and wide application fields in my country. [0003] The spring sowing corn area in northern China is dominated by the three northeastern provinces, Inner Mongolia and Ningxia. The planting area is stable at more than 6.5 million hectares, accounting for about 36% of the country; the total output is more than 27 million tons, accounting for about 40% of the country. Due to poor weather conditions during sowing, especially drought and w...
