Seed moisture content can be determined by drying method, can also be identified using the following simple method:
The tooth bite breaks the seed with teeth, and it is a dry seed (water content below 15% for rice and below 14% for wheat) that feels hard and brittle (squeaky). Otherwise it is a seed with high water content.
Seeing that the rice grain is brittle and that the rice skin is hairy, it is a relatively high-moisture performance, and the water content is about 15% or more. On the contrary, the belly white is small, the rice grain is hard and complete, and the rice husk is smooth and shiny, and the water content is relatively low. Its moisture is generally below 13%. The depression of the corn seed embryo is also dry, with about 14% moisture.
Listening to a handful of seeds falling from a height, or stirring the seeds by hand, if the sound of crisp, rapid and loud rustling, and dander, is a dry performance, such rice seed moisture content of about 13%.
Hand touch the hand into the heap of seeds, if you feel the seeds smooth, easy to reach into the bottom, or in the summer feel the seed grain rough and astringent, the hand is not easy to insert, even when the hand is pulled out, there are often some seed particles adhere to the back of the hand or Between the fingers, there is a high water content.
The stick will sharpen one end of the fine wood stick or bamboo stick and insert it into the seed pile. Pull it out the next day to see if there is any dampness or temperature rise to identify whether the seed is overly watery.
