施肥

Experimenting with different approaches can serve as a rich cross-fertilization for the future (as evidenced by your interesting question).

实验方法不同可作为一个丰富的跨）施肥对未来（有趣的是证明了你的问题。

This paper discusses an intelligent spatial decision support system for variable rate fertilizing of precision agriculture, VRF-ISDSS.

介绍一个具有数据库、知识库、方法库与模型库，用于精细农业中变量施肥的决策支持系统VRF -ISDSS。系统包括农业区的基础地理信息、作物生产知识、作物生长养分需求的数学模型和分析方法。

The difference of soil nutrient between operation units can be learned from the maps, and the decision and operation for variable rate fertilization can be made according to the difference.

应用实践表明：建立的田间土壤养分信息库可以应用于精确农业变量施肥的决策和作业管理

In addition to controlling insects, bacterial diseases, and weeds, crop dusting can be used to apply fertilizers, delay fruit ripening, increase or decrease the number of fruit a plant produces, and defoliate plants to facilitate harvest.

此外，以控制害虫，细菌性病害和杂草，作物喷粉，可以用来施肥，延迟果实成熟，增加或减少的水果植物数目的生产，和落叶植物以方便收获。

A setting sun casts a fiery glow over a crop duster spreading pesticides in a Brawley, California, field. In addition to controlling insects, bacterial diseases, and weeds, crop dusting can be used to apply fertilizers, delay fruit ripening, increase or decrease the number of fruit a plant produces, and defoliate plants to facilitate harvest.

It has the negative correlation with Cu、nicotine,has positive correlation with Zn、Cl and has negative correlation with deoxidize sugar/N.

因此深入研究土壤肥力与烟叶化学成分的关系，了解土壤肥力对烟叶化学成分的影响，能为改善植烟土壤环境、提高烟叶质量和合理施肥提供一定的科学依据。

The research in adsorption and desorption of nitrogen and phosphate is crucial to application of fertilization and environmental pollution prevention.

研究土壤对氮、磷的吸附/解吸附特性对合理施肥、防止环境污染等有重要的作用。

In this paper, phosphorus sorption and desorption in Albic soil were studied under long- term fertilization.

对白浆土在长期施肥条件下磷的吸附与解吸进行了研究。

In this paper,the research history and status were summarized.The processes of soil nitrogen input,interior transformation and output,including litter return,fertilization,atmosphere desposition,ammonification nitrogen fixation,ammonification,nitrification,denitrification,plant uptake,NH 3 volatilization and NO 3- leaching,were introduced.Finally,the tendency of study on soil nitrogen...

本文综述了森林土壤氮素转化与循环的研究历程和现状；介绍了凋落物的归还、施肥、大气沉降、自生固氮、氨化、硝化、反硝化、植物吸收、NH3 的挥发、NO3 -淋溶等土壤氮素输入、转化和输出的途径和过程；最后从研究目标、研究方法、研究对象和研究内容 4个方面归纳了森林土壤氮素转化与循环的发展趋势。

Perhaps it would be better to allow them to die off and fertilize the garden naturally.

但留下它们是为你菜园施肥的最好方式。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
