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 embodiment, a high-precision 1 / 2MS (containing carbon source and fixed medium) (containing carbon source and fixed medium and fixed medium) solid culture substrate large-scale production method, including accurate calculation, accurate weighing, first less Afterwards, there are six steps of mixing, sealing, separate mother liquor preparation, and unsealing for use.

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

[0016] ① Accurate calculation: expand the 18 elements contained in the MS basic medium by 1000 times, that is, 0.1g of thiamine hydrochloride, 0.25g of sodium molybdate dihydrate, 0.5g of nicotinic acid, 0.5g of pyridoxine hydrochloride, and 0.83g of 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 dihydroge...

Abstract

The invention discloses a large-scale preparation method of a high-precision 1 / 2MS (containing carbon sources and fixed media) culture medium, belonging to the plant biotechnology field. The large-scale preparation method comprises the following steps: firstly computing the quantity demands after 18 elements contained in the medium are increased by 1000 times and the quantity demands after CuSO4.5H2O and CoCl2.6H2O with minimal quantity demands are increased by 10000 times; accurately weighing chemicals after increase; successively mixing the 18 elements uniformly according to the quantity demands and sealing a solid medium; dissolving CuSO4.5H2O and CoCl2.6H2O in the quantity demands with 1L of distilled water for later use; and respectively unsealing the solid medium as needed to be used. The large-scale preparation method has the beneficial effects that the medium prepared by the method has the characteristics of high precision, convenience and quickness in operation, simplicity in application and small errors between different batches and in the batches; the phenomena such as large errors, precipitation and mouldiness, caused by manual operations and impacts of external factors, are avoided; the method can be applied to the biotechnology such as plant tissue culture.

Description

technical field [0001] The invention discloses a large-scale production method of a high-precision 1 / 2 MS (containing carbon source and fixed medium) 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 e...
