The effects of improving soil fertility by organic materials(ISFOM) on the composition, C, N distribution and activity of microaggregates were studied with field experiments in Brown earth and Black soil. The method used in this paper for preparating microaggregates was also evaluated. The results were summarized as follows; 1, the dominant and secondary dominant partical sizes in the soils were 10-50 and 50-250|im, respectively. The C, Ndistribution in various partical sizes of...

The effects of improving soil fertility by organic materials(ISFOM) on the composition, C, N distribution and activity of microaggregates were studied with field experiments in Brown earth and Black soil. The method used in this paper for preparating microaggregates was also evaluated. The results were summarized as follows; 1, the dominant and secondary dominant partical sizes in the soils were 10-50 and 50-250|im, respectively. The C, Ndistribution in various partical sizes of microaggregates were generally in follow sequence: 10- 50>50 - 250^0- 5> 5-10|am fractions; 2, the carbon activity(CA)and nitrogen activity(NA)were increased with the increase of the partical size of microaggregates; 3, the content of 50-250|am partical size in microaggregates composition and the CA, NA of various sizes of microaggregates were basically increased after EJFOM; 4, the sedimentation siphonage method for preparation of microaggre-gates is available before a new method found.

本文通过田间试验研究了土壤有机培肥(ISFOM)对棕壤和黑土微团聚体组成及其碳、氮分布和活性的影响。并对本文所用的制备微团聚体的方法进行了评价。结果表明:①棕壤和黑土的优势粒级和次优势粒级分别为10~50μm和50~250μm,C、N分布一般为10~50μm>50~250μm≥0~5μm>5~10μm。②随粒级的增加,棕壤的碳活性(C_A)和氮活性(N_A)提高。③ISFOM后一般使50~250μm粒级含量、各级微团聚体的C_A和N_A增加。④在没有更好的方法以前,用沉降虹吸法制备微团聚体是可行的。

This paper deals with the effect of improving soil fertility by organic materials on the optical properties and the activation degree of humic acids from brown earth in field and incubation experiments. The results are summarized as follows; the logK and activation degree increased, whereas RF value decreased under treatment, which suggested that humic acids molecule became less complex and more aliphatic. The humic acids of 50- 250 um particle fraction were more sensitive to treatment. The concept and...

This paper deals with the effect of improving soil fertility by organic materials on the optical properties and the activation degree of humic acids from brown earth in field and incubation experiments. The results are summarized as follows; the logK and activation degree increased, whereas RF value decreased under treatment, which suggested that humic acids molecule became less complex and more aliphatic. The humic acids of 50- 250 um particle fraction were more sensitive to treatment. The concept and the method for evaluating the activation degree of humic acids was also provided first in this paper.

本文通过田间和模拟试验研究了棕壤施用有机肥料对土壤胡敏酸(HA)光学性质和活化度的影响。结果表明,土壤有机培肥(ISFOM)使棕壤HA的色调系数(Δlogk)和活化度升高,相对色度(RF)下降,说明HA的分子结构简单化和脂族化。ISFOM对大粒级(50~250μm)中HA的影响较大。本文还提出了HA活化度的概念及测定方法。

To study the effect of improving soil and applying manure experiment on growing for Panax Quinquefolium. The result shows that adding 20% plant ash made root system of Panax Quinquefolium increase 2% in length, 22% in thick. The yield of fresh Panax Quinguefolium is 1250~15000kg·hm -2. Many experimental data and main technical points are provided in this paper.

研究北方农田退化黑钙土经过改土施肥处理,对西洋参生长发育的影响。试验结果表明,黑钙土壤中掺20%草炭灰西洋参根系增长2%,增粗22%,增重45%。施混合畜肥体根系增长18%,增粗39%,增重45%。每hm2(公顷)平均产鲜参1250~15000kg。报告中提供一些具体试验数据和技术要点
