查询词典 soil

The soil had great population of bacteria, but the fungi quantity is excessive which may cause the multiplication of germina. As base-fertilizer, the slowed-release fatty had positive influence on soil fast-effect nutrient, but the organism quality is small, the soil enzyme activity with microorganism activity both low. Soil EC, total nitrogen, available nitrogen, available phosphorus and organic matters were significantly negative related to the soil pH. Soil total nitrogen was positive significantly related to soil available nutrient.

Because of the regional difference of soil and climatic conditions, the division of 4 stages of soil moisture circulation is not all the same between different areas; the soil moisture dynamics between different dry farming areas in the Yellow River Basin is contrasted in this report. The results indicate that soil moisture increases gradually from dry semi-arid area to semi-arid area, dry semi-humid area and semi-humid area, and the high value district generally appears during soil moisture resuming period in rainy season or soil melting period. While the low value district appears at the stage of fast evaporation in spring or slow evaporation in autumn; in views of vertical changes of soil moisture, it is showed that the variation range of upper lays is larger than that of lower among the different dry farming areas in the Yellow River Basin.

Uses method which the field investigation sample and the indoor analysis unify, 2007-2008 years live the unicast awnless brome lawn and the awnless brome and the alfalfa interlacing in the Inner Mongolian nationality university agriculture school test farm take 2 years mix broadcast the lawn and the colleague mix broadcast the lawn as the objects of study, have studied under the different sowing seeds way the forage grass to the soil physics and chemistry nature influence, finally indicated:the change tendency which under the different sowing seeds way increases the soil bulk specific gravity overall along with the soil layer depth to present after reduces first increases, is the 10-20cm soil layer is lowest; Looking from the 0-40cm soil layer's mean value, the unicast awnless brome lawn soil bulk specific gravity is smallest, the colleague mixes broadcasts the lawn soil bulk specific gravity to be biggest.

科尔沁草原是典型的农牧交错地区，长期以来，由于不合理利用草地资源造成该区生态环境严重恶化，农牧业生产受到严重影响[1]。建立高产优质的人工草地是解决我国高寒地区草畜供求季节不平衡的矛盾，促进草地畜牧业持续发展的关键措施之一[ 2]。无芒雀麦和紫花苜蓿都是营养价值高、适口性好、抗寒抗旱能力强的多年生牧草。将这两种牧草混播不仅能提高牧草产量和品质，延长草地使用年限，还能改善牧草的营养，提高牧草的适口性，有利于调制和青贮[3]。
