TL;DR: Water extracts from roots and stems of lambsquarters, and roots, shoots and inflorescences of foxtail at 3 mg.ml−1 stimulated growth of the bacterium by more than 40 times the control, and similar extracts from several other plants were marginally stimulatory.
Abstract: Yeast extract-mannitol broth supplemented with 3 mg.ml−1 extract from aerial parts of plants was noculated withB. japonicum 3I1b110. Filter-sterilized water extracts of foxtail (Setaria viridis), lambsquarters (Chenopodium album), Johnsongrass (Sorghum halepense) and Pennsylvania smartweed (Polygonum pensylvanicum) stimulated growth of the bacterium by 3–4 times after 48 h incubation; however, similar extracts from several other plants were marginally stimulatory. Autoclaved water extracts and methanol (75%) extracts were less stimulatory than filter-sterilized water extracts. Autoclaved water extracts of nutsedge (Cyperus esculentus) and ragweed (Ambrosia psilostachya), and methanol extracts of smartweed, peat and ragweed depressed growth of the bacterium. Filter-sterilized water extracts from shoots of foxtail and lambsquarters increased growth of the bacterium linearly up to 6 mg.ml−1. At that level growth in the presence of lambsquarters shoot extract was almost 20 times that of the control. Comparable growth stimulation by this extract was also found in four other strains ofB. japonicum. The water extracts from roots and stems of lambsquarters, and roots, shoots and inflorescences of foxtail at 3 mg.ml−1 stimulated growth of the bacterium by more than 40 times the control.

TL;DR: In this article, a polygonum multiflorum bio-fertilizer is proposed to resolve indissolvable phosphorus and potassium in soil, the soil fertility is improved, phosphorus and Potassium are absorbed and used by polygonal multiflora, and consumption of the fertilizer is reduced.
Abstract: The invention discloses a polygonum multiflorum biofertilizer, and a preparation method and application thereof. The polygonum multiflorum biofertilizer is prepared by the following raw materials in parts by weight: 1500 parts of farmyard manure, 4.5 parts of quicklime, 18-22.5 parts of microbial inoculum, 200 parts of calcium magnesium phosphate fertilizer, 60 parts of urea, 6 parts of borax fertilizer, 14 parts of potassium sulphate fertilizer, 6 parts of manganese sulfate fertilizer and 0.5 parts of sodium molybdate fertilizer. The prepared polygonum multiflorum biofertilizer uses phosphate-solubilizing and potassium-solubilizing microoganisms to resolve indissolvable phosphorus and potassium in soil, the soil fertility is improved, phosphorus and potassium are absorbed and used by polygonum multiflorum, and consumption of the fertilizer is reduced. The raw material of the polygonum multiflorum biofertilizer, the microbial inoculum, can also be used for producing a phytohormone substance to stimulate and regulate growth of the polygonum multiflorum, the polygonum multiflorum grows strongly, the nutritional status is further improved, and further the yield and quality of the polygonum multiflorum are increased and improved.

TL;DR: It is concluded that basal infusion of precursors is not the most suitable technique for studies of phenolic biosynthesis because it contained more insoluble radioactivity than the terminal ones.

TL;DR: In this article, a preparation process of polygonum multiflorum medicinal slices is described, which successively comprises the following steps: excavating when polygonal multiflorus leaves wither in autumns and winters; cutting two ends, and cleaning; cutting big polygonumm multiflorums into cubes, and drying; removing mud, dust, mildew spots and other dirty substances on the surface of the polygonus; cleaning the polygomedia; uniformly stirring the cleaned polygonuma multifloruma with black bean juice which accounts for 8 to 12 percent of
