          If the crop is not good, it may be that the rice blast is stealing and how to solve the problem.

          Both adults and nymphs of brown rice blast can be harmful, and they accumulate at the base of rice plants to absorb juice, which hinders the growth of rice.
          The lower part of the rice grove became dark brown, and gradually the whole plant withered. After the rice is threatened at the booting stage, it is often impossible to produce spikes or empty spikes that are “necked”;
          After being killed after heading, it will affect the grain fullness and the 1000-grain weight will drop, causing serious yield reduction. During the feeding period, brown rice blasts easily make rice
          The plant developed soot. In addition, brown rice bran can also spread rice virus disease.
          So; how do we deal with these pests? The best way is to make insecticides that are dedicated to killing these pests, but the same
          When you can't hurt the growth of crops, what can you do?
          Extract the DNA of rice blast, study its characteristics and test the effect of pesticides on its DNA, so that they can not harm crops, guarantee Zhuang
          The crop can thrive.
          The traditional grinding method has a very large sample loss, and cannot guarantee the sampling amount of DNA. If there is a grinding machine with high grinding efficiency, it is helpful.
          Researchers can ensure that the grinding sample is large, without loss and at a very fast rate. The tissue grinder is a special type.
          A fast, efficient, multi-tube consistent system. It can be used from any source (including soil, plant and animal tissues/organs,
          The original DNA, RNA and protein of bacteria, yeast, fungi, spores, paleontological specimens, etc. are extracted and purified.

          Experimental steps:
          Step 1: Prepare the centrifuge tube,
          Step 2: Add a few grinding beads and add the sample;
          Step 3: Set the parameters
          Step 4: Take out the sample and do the follow-up experiment
