农业化肥

The invention use an alcaligenes faecalis as a fermentation strain, using sucrose or glucose commonly used in food industry as carbon source for microbe cultivation, using conventional chemical fertilizer in the agricultural production as nitrogen source and inorganic salt, the medium of microbial growth is prepared by auxiliary yeast powder, aerobic fermentation is processed in the conditions of 30 DEG C, 1.0vvm, 500r/min ventilatiing and stirring, adding specially supplementary food fluid in the fermentation course achieves the following aims:(1) controlling the penetrating pressure of the broth in the hypotonicity condition;(2) controlling the pH of the broth between 4.0 and 7.0;(3) providing abundant nutritious matter such as carbon source and nitrogen source for microbial growth, obtaining Weilan gum broth after 72 hours, obtainin Weilan gum product by drying in 95-115 DEG C and atmospheric pressure.

本发明以一株粪产碱杆菌为发酵菌种，使用食品工业中常用的蔗糖或葡萄糖作为微生物培养的碳源，以农业生产中常用的化肥作为氮源和无机盐，辅以酵母粉配制微生物生长的培养基，在30℃以1.0vvm、500r/min通风搅拌条件下好氧发酵，发酵过程中流加特殊配制的补料液以达到以下目的：(1)控制发酵液的渗透压处于低渗条件；(2)控制发酵液的pH处于4.0～7.0之间；(3)为微生物生长提供丰富的碳源和氮源等营养物质，经72小时得到威兰胶发酵液，在95℃～115℃下常压干燥得到威兰胶产品。

To inoculate beneficial microorganisms has been the topic of scientist to cope with it.

在生态农业中，通过向土壤中接种有益微生物部分替代化肥已是科学家研究的热点。

The chemical fertilizer of traditional agriculture, fertilizer and jobber can disappear.

传统农业的化肥、肥料和批发商可以消失。

On the basis of satellite remote sensing image,GIS was applied to analyze 3-demension information about the geomorphy to investigate the non-point source pollution distribution in association with soil erosion information, and thus to pinpoint the essential pollution control region.

我国东部湖泊的污染负荷输人量中，农业非点源污染负荷人湖量已超过50%，大理洱海流域非点源污染氮、磷分别占流域污染负荷的97.1%和92.5写，农田过量施用化肥是造成非点源污染的主要原因图。

Implementation of conservation tillage, decrease of chemical fertilizer application, increment the rate of straw returning to field and organic fertilizer, should be the primary regulation direction of geoponic management in the future.

实施保护性耕作、降低化肥用量、提高秸秆还田量和有机肥的用量成为今后农业生产管理方式调整的主要方向。

Implementation of conservation tillage, decrease of chemical fertilizer application, increment the rate of straw returning to field and organic fertilizer, should be the primary regulation direction of geoponic management in the future.

实施保护性耕作、降低化肥用量、提高秸秆还田量和有机肥的用量成为今后农业生產管理方式调整的主要方向。

Because nitrogen oxides were already present on early Earth, our finding opens up the possibility that oxygen was available to microbial metabolism before the evolution of oxygenic photosynthesis.

同时，由于亚硝酸盐通过化肥的使用而在淡水农业土壤中大量存在，新的研究结果也可为肥料在甲烷循环中的利用提供契机。生物谷 Bioon.com

The introducing arrangement for this chapter is: Firstly, analyzing the amount of fixed asset investment at the whole society and rural areas(including the collections and the personals);analyzing the amount of fixed asset investment at the eastern, middle and the western provinces by second; after that, doing the up-date of farmer's investment and the rustically personal fixed asset investment at the eastern, middle and the western provinces; fourthly, making the analyses on the Agriculture, forestry, animal husbandry and fishing, labor forces, amounts of chemical fertilizer-spraying and the actuality of watering irrigation; fifthly, analyses on the actuality of agriculturally basic construction investment in this chapter; sixthly, nationally financial investment; taking the up-date of nationally financial investment , especially the ones being used to support the farmers with the following;and finally, the up-date of other investment owner being analyzed.

首先，分析了全社会、农村固定资产投资额。其次，分析了东中西部省区农村集体固定资产投资。第三，分析了农户投资的现状及东中西部农村个人固定资产投资。第四，对农林牧渔、劳动力、化肥施用量和水利灌溉现状进行了分析。第五，对农业基本建设投资的现状进行了分析。第六，对国家财政投资，尤其是财政支农投资现状进行了分析。第七，对其它投资主体的现状进行了分析。

Today, agricultural experts estimate that in many parts of China fertilizer use can be slashed by up to 60%.

现在，据农业专家们估计，在中国的许多地区，化肥的使用可能削减了达60%。

Grain yield per hectare is the most important factor in the method of the gray system analysis. There was significant correlation between effective irrigated area, the amount of fertilizer applied, mechanical power and the grain yield. The area of grain and the population of agriculture are factors that affect grain production. The correlation coefficient of natural resources and grain production changes unstably.

单产与粮食产量始终保持很高的关联度；有效灌溉面积、实际机耕面积、化肥施用量、农村用电量和农机总动力等农业投入对粮食产量提高影响重大；耕地面积和劳动力对粮食产量具有一定的制约；自然条件与粮食产量的关联度剧烈变动。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
