Description
Technical field
The present invention relates to coating agent for seed technical field, and in particular to a kind of corn seed coating agent and preparation method thereof.
Background technology
Corn is most important food and feed resource, is that China has the call and answered as second-biggest-in-the-world crop
With one of extensive staple food crop in field.
North of China Spring maize seeding area, based on three provinces in the northeast of China, the Inner Mongol and Ningxia, due to sowing when weather conditions it is poor,
Particularly drought and water shortage and disease is serious, causes that corn seed germination rate is relatively low and seedling growth is weak, so as to finally have impact on jade
The yield of rice.Therefore the corn seed of northern dry land after planting how is enable to have sufficient moisture and nutrition to promote its sprouting
And seedling growth, it is the key for improving this area's corn yield.At the same time, almost all of corn variety not Salt And Alkali Tolerance,
Corn seed survival rate in salt-soda soil is low, does not have a good harvest.There is no effective ways to solve corn seed in salt-soda soil at present has abundance
Moisture and enough nutrition ensure its germination percentage and promote maize seedling growth, while resist disease and saline-alkali land stress ask
Topic.
The content of the invention
The purpose of the present invention is to be directed to problem of the prior art, there is provided a kind of corn seed coating agent and preparation method thereof.
