Seed moisture content can be measured by the drying method, you can also use the following simple method to identify: 1, tooth bite: the teeth bite off the seeds, feeling hard and crisp (squeak sound), smooth section is a dry seed (rice species Water below 15%, wheat below 14%, otherwise it is a seed with high water content. 2. Seeing: rice grains are fragile and rice grain is hairy, which is a high water content. The moisture content is about 15% or more. On the contrary, the white belly is small, the grain is hard and complete, the rice grain is smooth and shiny, and the water content is low. The performance of the water is generally below 13%. The depression of the corn seed embryo is also dry, with about 14% moisture. 3. Ear listening: Grab a handful of seeds falling from a height, or stir the seeds by hand. If a crisp, rapid and loud rustling sound is emitted, and there is dander, it is a dry performance. The water content of such rice seeds is 13 %about. 4, hand touch: Put the hand into the seed heap, 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 often there are some seed adhesion In the back of the hand or between fingers, it is a high water content. 5. Plunging stick: Sharpen one end of a fine wooden stick or bamboo stick and insert it into the seed heap. Pull it out the next day to see if there is any dampness or temperature rise to identify if the seeds are too watery. China Agricultural Network Editor
