Effects Of Cultivation Substrate And Fertilizer On Growth Of Potted Ginseng

Panax ginseng C.A.Mey and Panax quinquefolium Line are famous medicinal plants in China.It has the reputation of"King of Baicao",its green leaves,symmetrical body,and bright red fruit.Ornamental value,become the new darling of forestry ecotourism in recent years,especially potted ginseng as ornamental plants won the South and the city guests welcome.To meet the tourism market and urban people on the fresh ginseng favorite and curious,its potted form into the family,into the southern region and Changbai Mountain tourism market has great potential for development.But the current ginseng potted ornamental lack of technical support series,so research and development of potted plants series technology is imperative.(1)The pot experiment was carried out in six different treatments according to the different volume ratio,using the garden soil,the peat,the mountain fog leaf,the slag,the perlite and the river sand.The results showed that the comprehensive evaluation value of J1(mountain skin rot leaf soil)was the highest,and it was most suitable for potted ginseng,followed by J4 treatment,again for J6 treatment.The formula of J4(mountain peeling leaf:peat:2:1:1)was used as potted ginseng,and the growth of the ginseng,plant height,stem diameter,leaf area,polysaccharide and total saponin content,Water use efficiency was significantly better than other treatments,the use of peat and bacteria residue mixed,reducing the amount of mountain fog soil.(2)To J4 as potting substrate,set 4 base fertilizer treatment:CK not fertilization,treatment 1 Suzi fertilizer 100g/m2,treatment 2 soybean cake fertilizer 300g/m2,treatment 3 high concentration of potassium sulfate compound fertilizer 40g/m2.The results showed that the application of basal fertilizer was higher than that of CK,and the net photosynthetic rate and water use efficiency were high.The results showed that the content of polysaccharides and total saponins in root was less than that of treatment.1 Although the growth of leaf stage was slow,it had a tendency to rise slowly.Green fruit grows more than the time of treatment 3,the viewing effect is the best,to the end of the test has been better than the other three treatments,the growth period 6 times the root of polysaccharides and total saponins content are at the highest level.In the first and fifth determinations of the growth period,the difference in chlorophyll a+b content of the four treatments was:treatment 1>treatment 3>treatment 2>CK,where treatment 1 was 4.6 times that of CK and net photosynthesis The rate is also highest.I recommend:potted American ginseng base fertilizer preferred Suzi fertilizer,followed by the use of high concent rations of potassium sulfate compound fertilizer.(3)All-nutrient enzymes were subjected to 4-factor 4-level orthogonal design tests and sprayed in the form of foliar top dressing.The results showed that the optimum combination of ginseng growth of the whole nutrient enzyme was 700 times the photosynthetic enzyme+1100times the structure of the enzyme+6000 times the open enzyme.On this basis,set CK(water)control,Z1(700 times photosynthetic enzyme+1100 times the enzyme+6000 times the open enzyme+700 times the pollen enzyme),Z2(green peon root root seedling:700 times the water+1750 times powder),Z3(0.3%urea+0.3%potassium dihydrogen phosphate)4 treatment.The results showed that the stem diameter of each treatment was 1.65 times,2.08 times,1.87 times and 2.20 times,respectively,and the ratio of CK was higher than that of CK 26.37%,13.33%,33.33%;Z3 treatment of the best viewing characteristics.The net photosynthetic rate and water use efficiency of potted ginseng were significantly different from CK(P<0.05),and ZI was the first.The chlorophyll content of leaves was the highest,and the chlorophyll content of Z1 was the highest,which was significantly different from that of other treatments(P<0.05).Ginseng root polysaccharides every time higher than other content.It is concluded that the whole nutrient enzyme has a significant effect on improving the quality of potted ginseng.Followed by urea and potassium dihydrogen phosphate combination.
