Study On The Nutrient Effect Of Juice-Bio-Fertilizer

The effects of seven kinds of wild plant juice exacted from Sambucus Chienesis Lina.,Clerodendrum colebrookianum Walp.,Artemisia annua L.,Alternathera philoxeroides Grisb,Uritica L.,Rubus Lambertianus Ser.,Amaranthul S. and juice-bio-fertilizer(JBF) on plant growth,yield and quality was studied by means of cultivation experiment and field experiment. The results as follow:(1) In seven kinds of wild plant juice, Sambucus Chienesis Lina..,Clerodendrum colebrookianum Walp., Alternathera philoxeroides Grisb,Amaranthul S .could promote the growth ,increase the yield and improve the quality of capsicum apparently. Clerodendrum colebrookianum Walp.and Sambucus Chienesis Lina are better than others. The yield of capsicum which treated by Clerodendrum colebrookianum Walp.and Sambucus Chienesis Lina juice was increased by 15.1 percent and 14.6 percent respectively,the content of nitrate was decreased by 13.2 percent and 10.4 percent respectively.(2) Drenching wheat with juice of Sambucus Chienesis Lina.,Clerodendrum colebrookianum Walp.and Alternathera philoxeroides Grisb was benefit to the growth of wheat. The plant height,root length and the ratio of root /corona were prompted apparently. The three kinds of juice of Artemisia annua L.,Uritica L.,Rubus Lambertianus Ser. had little prompt using on wheat's growth. The juice of wild plant could also increase wheat's content of chlorophyll and enhance photosynthesis. Furthermore,the root's absorption on nutrient was prompted through increasing root activity.(3) Low concentration of mineral nutrient had little influence on microorganism. When the concentration of mineral nutrient was less than 3 percent,it had some prompting effect on microorganism. High concentration of mineral nutrient had apparent restraint on microorganism. When the concentration of mineral nutrient was greater than 6 percent,the number of microorganism decreased promptly.(4) It was reasonable with wild plant juice act as the carrier of the microorganism. The activity of the microorganism was increased and the lay intime was elongated when Sambucus Chienesis Lina juice was added into the microorganism liquid Furthermore Sambucus Chienesis Lina juice could decrease the toxic action of mineral nutrient to the microorganism,and increased the ability of enduring salt.(5) JBF which compounded with wild plant juice,mineral nutrient and microorganism could increase the yield and improve the quality of vegetable. Especially in decreasing the content of nitrate and increasing the content of vitamin C. The effect of Sambucus Chienesis Lina,Clerodendrum colebrookianum Walp and Alternathera philoxeroides Gris juice bio-fertilizer was proved to be the best,the yield of pot capsicum was increased by 13.5 percent,10.31 percent and 9.2 percent,the content of nitrate was decreased by 10.25 percent,9.43 percent and 13.52 percent respectively,the content of vitamin C of pot capsicum was increased by 25.53 percent,21.31 percent and 12.65 percent respectively.(6) JBF could improve the physical and chemical character of soil,enhance the fertility of soil,and lead the soil nutrient into a beneficial recycle. It embodied that the content of soil organic matter increased,soil unit weight improved,and the number of soil microorganism increased.
