本文仅提供一些有关胡敏酸钠的田间实验资料与一些室内辅助实验资料.实验是1959在北京农业大学进行的,供试植株是春小麦(南大2419);土壤为北京西郊褐色士;胡敏酸钠从北京万寿山人民公社的草炭中提取,没有用酸沉淀,直接用丘林法定破后冲稀应用.制成的胡敏酸钠,按作物不同生长期灌溉.施用浓变为100、50、10p.p.m.及对照.土壤、土壤微生物、植物等分析按一般常规方法进行.一、对土壤微生物的影响:在整个供试植株的生长期中,我们做了二次土壤微生物分析.
This paper provides only some field experimental data on sodium huminate and some laboratory-assisted experimental data. The experiment was conducted at Beijing Agricultural University in 1959. The test plant was spring wheat (Nanda 2419); the soil was brownish-brown in western Beijing; Sodium soda was extracted from the peat of Beijing’s Longevity Hill People’s Commune without acid precipitation and was directly applied to the forest by the Chulin law. The sodium huminate was then irrigated at different growth stages and the concentration was changed to 100, 50, 10p.pm and control Soil, soil microorganisms, plants and other analysis according to the general method of A. First, the impact on soil microorganisms: throughout the growing period of the tested plants, we did a second soil microbial analysis.
