, 2023 非损伤微测技术(NMT)作为生命科学领域的关键核心技术,已帮助中国科研学者在包括Cell、Nature、Science 等在内的各类学术期刊上发表各类文献超过1200 篇,但由于NMT 目前依然属于普及度不高的新技术,初次接触NMT 的研究人员,需要花费较高地时间成本来收集NMT 相关资料,以了解并学习NMT 的使用。 为了能够让研究者们更系统、高效地学习NMT,我们汇总了国内NMT 领军企业旭月公司及超过1000 位的中国科研学者和工程技术人员,在近二十年的时间里总结出的应用经验和体系视频资源 ...

Do diverse landscapes provide for effective natural pest control in subtropical rice?
Journal of Applied Ecology, Volume 57, Issue 1, Page 170-180, January 2020., 2020 Our findings question the cost‐effectiveness of current chemical‐based pest management in farming, and highlight opportunities for more ecologically based pest management strategies based on the widespread activity of natural enemies. Pest damage and biocontrol, however, are largely independent from the landscape context, which might be due to the ...

Shuitu Baochi Xuebao, 2006 研究了分次施氮条件，施氮对水稻根际土壤微生物生态效应的影响，结果表明：水稻根际土壤微生物生态效应不仅仅受到根际土壤微生物的影响，同时也受到水稻生长状态的影响。一般来说，水稻生长旺盛的时候，水稻根系与根际土壤微生物竞争营养元素，导致水稻根际微生物活性的下降。在水稻生长周期内，水稻根际土壤微生物生物量C与根际土壤酶等变化不一致。分次施氮条件下，施氮对根际微生物生物量C、磷酸酶、脲酶、总蛋白和总酚有一定的影响，尤其是在水稻生长的后期，4次施氮全部完成后，施氮与不施氮表现出明显的差异。

Shuitu Baochi Xuebao, 2020 针对水稻生产中存在秸秆处理不当以及化肥用量增多等问题，以山东省济宁市稻麦轮作体系下水稻"圣稻18号"为研究对象，通过田间试验设置3个处理：常规施肥，小麦秸秆不还田（CK）；常规施肥+小麦秸秆全量还田（T1）；常规施肥量的85%+小麦秸秆全量还田（T2），深入探究秸秆还田与化肥减施对不同生育期水稻生长、光合参数和产量的影响，为制定合理的水稻种植措施提供理论依据。结果表明，稻麦轮作体系下秸秆还田不利水稻前期生长，但能显著提高水稻生长中、后期的生长指标，并增强水稻生长中、后期对氮、磷、钾等养分的吸收 ...

Shuitu Baochi Xuebao, 2006 采用^15N-尿素进行盆栽和田间试验，研究了复合氮肥增效剂用量、尿素与复合氮肥增效剂配施对水稻生长、籽粒产量和氮素吸收利用的影响。结果表明，适宜用量（施氮量的20％）的复合氮肥增效剂能显著促进水稻幼苗生长发育；尿素全量配施复合氮肥增效剂不影响水稻生长，能显著提高水稻植株Ndff％、氮吸收总量，氮素利用率和^15N的吸收量,尿素减量5％～15％（即减少施氮7．8～23．7kg／hm^2）配施复合氮肥增效剂基本上不影响水稻生长、籽粒产量和吸氮总量，能显著提高氮素的农学效率、生理效率和氮素利用率；植株吸氮总量、

Research on the Livelihood and Changes of GuangHui Village in North Hunan Province [PDF]
, 2016 光辉村是湘北地区典型的多姓氏杂居村落，该村所拥有的河湖平原地貌与亚热带季风气候使得村民形成了与之相适应的以水稻种植为主的生计方式。作为一个传统上以水稻种植业为主的村落，种粮是村民们最主要的生计手段。除种植水稻外，村人还种植蔬菜、养殖禽畜与鱼类作为粮食生产以外的补充，以此能够自给自足。自上世纪80年代以来，光辉村的生计模式经历了从“水稻种植为主体、蔬菜种植、渔业、禽畜养殖为补充的传统自给自足的农业生计模式”转变为“农业为主体、外出务工为补充的生计模式”，之后再转变为以“农业为基础、外出务工为主体的生计模式”
