Problems solved by technology

However, because the mother liquor contains different types of reagents, it is often divided into four major categories: macroelements, trace elements, iron salts and organic elements, and the expansion multiples of the four categories are different, resulting in inconsistent quality of medicines, and one is prone to calculation errors; Two, the manufacturer and quality of the medicine are inconsistent, even if the calculation and weighing are consistent, it will affect the test results; three, because the mother liquor is in a liquid state, at the turn of spring and summer, due to the increase in temperature and humidity, it is extremely easy to cause mother liquor infection Bacteria and mold cause different colors or precipitation in the mother liquor, which wastes raw materials; four will cause large errors due to the difference in the scale of the container (especially trace elements) and the precision of the instrument.
[0003] In view of the above-mentioned shortcomings of mother liquor preparation, the preparation of culture medium with conventional mother liquor often leads to failure or unrepeatable test results due to factors such as weighers, drugs, seasons, etc., which greatly affects the use of plant tissue culture or culture media. The process of carrying out trials of soilless cultivation technology has hit the confidence of the experimenters

Embodiment Construction

[0013] The present invention will be further described below in conjunction with specific embodiments.

[0014] In this example, a large-scale production method of high-precision MS (containing carbon source and fixed medium) solid culture substrate, including accurate calculation, accurate weighing, first mixing less and then more, sealing, separate mother liquor preparation, unpacking and using Wait for six steps.

[0015] The specific operation of the above six steps is as follows:

[0016] ① Accurate calculation: expand the 16 elements contained in the MS basic medium by 1000 times, namely 0.1g thiamine hydrochloride, 0.25g sodium molybdate dihydrate, 0.5g nicotinic acid, 0.5g pyridoxine hydrochloride, and 0.83g potassium iodide , glycine 2g, boric acid 6.2g, zinc sulfate heptahydrate 8.6g, manganese sulfate tetrahydrate 22.3g, sodium iron edetate 36.5g, inositol 100g, potassium dihydrogen phosphate 170g, magnesium sulfate heptahydrate 370g, dihydrate Calcium chloride 44...

Abstract

The invention discloses a scale production method of a high-accuracy MS culture substrate, and belongs to the technical field of plant biology. The method comprises the following steps: firstly, calculating the quantity demand of 18 elements which are contained in the MS basic solid culture substrate and are enlarged by 1,000 times and the quantity demand of CuSO<4>.5H<2>O and CoCl<2>.6H<2>O which is enlarged by 10,000 times; accurately weighing drugs; sequentially mixing and sealing the 16 elements according to the quantity demand; dissolving CuSO<4>.5H<2>O and CoCl<2>.6H<2>O by using 1L of distilled water for later use; unsealing and using respectively according to the requirement. According to the method, the prepared substrate has the characteristics of high accuracy, convenience and quickness in operation, simpleness in application, small errors in different batches and in the same batches; particularly, the weighing errors of the drugs CuSO<4>.5H<2>O and CoCl<2>.6H<2>O with extremely low contents are avoided, and the scale production method can be applied to biological technologies such as plant tissue culture.

Description

technical field [0001] The invention discloses a large-scale production method of a high-precision MS culture substrate, belonging to the field of plant biotechnology. More specifically, it includes six steps including accurate calculation, accurate weighing, mixing less and more, sealing, separate mother liquor preparation, unpacking and using, in order to obtain different batches and batches with minimal error A method for cultivating substrates and reducing experimental errors. Background technique [0002] Plant tissue culture technology or soilless culture technology usually requires the preparation of the mother liquid of the medium, that is, the preparation of a liquid that is enlarged by a certain multiple and contains various types of reagents. However, because the mother liquor contains different types of reagents, it is often divided into four major categories: macroelements, trace elements, iron salts and organic elements, and the expansion multiples of the four...
