Problems solved by technology

However, almost all corn varieties are not resistant to saline-alkali, and the survival rate of corn seeds in saline-alkali soil is low and the harvest is not good.
At present, there is no effective way to solve the problem that corn seeds in saline-alkali soil have sufficient water and nutrition to ensure their germination rate and promote the growth of corn seedlings, while resisting the stress of saline-alkali soil

Embodiment

[0025] The coating agent comprises 90% of polyaspartic acid, 4% of 80-fold diluted guaronic acid mother liquor, 5% of fruit shell powder, and the balance is ethylenediamine crosslinking agent in terms of mass percentage.

[0026] Preparation of coating agent:

[0027] (1) According to the above ratio, add guaronic acid mother liquor diluted 80 times (diluted with water) to polyaspartic acid, and stir evenly; (2) After mixing evenly, add ethyl alcohol to the mixture obtained in step (1). Diamine is used to improve the viscosity of the mixture; (3) pulverize Xantho sorbifolia powder on an ultrafine pulverizer until the fineness reaches more than 100 mesh; (3) evenly coat the high-viscosity mixture prepared in step (2) The cloth is placed on the outside of the corn seeds, and then wrapped with the obtained husk powder in the step (3) in proportion, and dried under natural ventilation conditions to obtain the coated corn seeds.

[0028] Said, the weight ratio between the seed and...

Abstract

The invention belongs to the field in which biologic materials are used for plating crops and in particular relates to a corn seed coating agent which is applied to saline and alkaline soil with a low pH value and has the functions of strengthening seedlings, strengthening root and retaining water and a preparation method of the corn seed coating agent. The coating agent comprises the following components in percentage by weight: 80-95% of polyaspartic acid, 2-10% of dilute waste gulconic acid mother liquid, 2-10% of xanthoceras sorbifolia bunge husk powder and 0.5-3% of a cross-linking agent. The corn seed coating agent has an effect of retaining water around the corn seeds in the saline and alkaline land soil; the pH value is low, so that the alkaline stress of the saline and alkaline land can be resisted to a certain extent; the germination rate of the corn seeds in the saline and alkaline land can be ensured; the corn seed coating agent has the functions of strengthening seedlings, strengthening root, increasing the content of chlorophyll in planet leaves and improving stress resistance. The preparation method of the corn seed coating agent is low in cost and simple and convenient to operate.

Description

technical field [0001] The invention belongs to the field of applying biomass materials to crop planting, and in particular relates to a corn seed coating agent suitable for saline-alkali soil with low pH value, strong seedlings and roots, and water-retaining functions and a preparation method thereof. Background technique [0002] The area of ​​China's saline-alkali land is about 100 million hectares, which is equivalent to China's 1.8 billion mu of cultivated land. According to the statistics of the three northeastern provinces, there are a total of 47.955 million mu of saline soil and alkaline soil. Most of them belong to the soda alkalization type, and the total salt content of the soil is not high, but it has a high pH value. These saline-alkali soils have high organic matter content, heavy clay texture, good water and fertilizer retention performance, and higher crop yields after reclamation and utilization. The transformation and utilization of saline-alkali land ha...
