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

[0012] The present invention will be further described below in conjunction with specific embodiments.

[0013] In this embodiment, a large-scale production method of MS basic solid culture substrate includes five steps of accurate calculation, accurate weighing, first mixing less and then more, sealing, and unsealing for use.

[0014] The specific operation of the above five steps is as follows:

[0015] ① Accurate calculation: expand the 18 elements contained in the basic solid base of MS by 1000 times, that is, 0.025g each of cobalt chloride hexahydrate and copper sulfate pentahydrate, 0.1g of thiamine hydrochloride, 0.25g of sodium molybdate dihydrate, and 0.5g pyridoxine hydrochloride, 0.83g potassium iodide, 2g glycine, 6.2g boric acid, 8.6g zinc sulfate heptahydrate, 22.3g manganese sulfate tetrahydrate, 36.5g sodium iron edetate, 100g inositol, Potassium dihydrogen phosphate 170g, magnesium sulfate heptahydrate 370g, calcium chloride dihydrate 440g, ammonium nitrate 1...

Abstract

The invention discloses a scale production method of an MS basic solid 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; accurately weighing the enlarged drug quantity, wherein CuSO<4>.5H<2>O and CoCl<2>.6H<2>O are accurately weighed by using a one over ten-thousand balance; sequentially mixing the 18 elements according to the quantity demand; sealing 250g of the solid culture substrate into a fixed plastic container; unsealing and using respectively according to the requirement. According to the method, the MS basic solid culture substrate which is enlarged by 1,000 times can be prepared, and the method has the characteristics of convenience and quickness in operation, simpleness in application, and small errors in different batches and in the same batches, and can be applied to biological technologies such as plant tissue culture.

Description

technical field [0001] The invention discloses a large-scale production method of MS basic solid culture substrate, which belongs to the field of plant biotechnology. More specifically, it is a five-step process including accurate calculation, accurate weighing, mixing less and more, sealing, and unsealing, in order to obtain culture substrates with minimal errors between different batches and batches, and reduce Method of trial and error. 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 categories are different, resulting in in...
