简介：瑞斯耕作长被认为从在某处在画热带野米饭的年度类型播种发源，热带或在长江盆。然而，当我们认为巨大的困难让原始的人在温暖、潮湿的气候播种任何谷物庄稼时，那个想法包含一个毁灭性地弱的点，在杂草全年繁荣的地方。而不是接受理论，我们不得不看见可食的植物的植物的繁殖是在如此的区域的农业的一种主导的形式的现实。可能性被讨论那个工作的眼泪和米饭，对这个区域唯一的二谷物庄稼，可能经由植物的繁殖被开发了在谷物生产以前在后院花园里为药或植物茶获得材料。这个想法被在适度的区域的米饭在它的生长习惯仍然是长期的并且有移植芋头的如此的后院花园能仍然从中国的云南省被看见到老挝的事实支持。由于在整个为19701980的中国的野米饭的详细调查，野米饭的一套克隆在江西省在浅沼泽地存在，这现在被证实，有严重冬季的一个区域冷。在早夏天，古老的农民可能划分了发芽的芽并且由移植进充满的浅沼泽地散布了他们。繁殖力量的如此的方法更快比的为对人的干扰的反应通过一个更好基因的潜力改进了不太高效的大米在种子繁殖的快固定，因为植物的部分是异构的。显然，大米耕作的如此的一种原始方式确实包括了大米耕作的必要部分，即，托儿所床，在浅沼泽地的充满的地里移植象一样。到由种子的真托儿所的从原始托儿所的转移以后可能允许米饭耕作被延长到北区域。在因此设计的充满的耕作，有一系列唯一的优点，即；在一个一样的阴谋的大米的连续收割，没有土壤侵蚀，土壤富饶的慢衰落，矿物质的可获得性，并且每统一区域导致高产量，它一起在温暖、潮湿的区域达到了高度高效的谷物耕作。在沼泽地的瑞斯耕作也是有利的提起鱼文化，哪个组成了一个营养地平衡的底。到充满的�

简介：一个壶实验被执行在在栽培变种，超级米饭变化Ningjing1和传统的变化Zhendao11，它当前是商业地在南京使用了的二米饭之间的植物生产率和CH4排放学习差别，中国。CH4排放流动和土壤答案CH4内容的类似的季节的变化在测试栽培变种之间被发现。尽管在在栽培变种之间的植物生物资源生产没有重要差别，Ningjing1的谷物收益在35.0%是显著地更高的(P<0.05)与比Zhendao11，而从Ningjing1的全部的CH4排放是，35.2%降低(P<0.05)。在在栽培变种之间的CH4排放的数量的主要差别从tillering阶段发生在时期到出发阶段。可伸缩生物资源、可伸缩收益的CH4排出物是分别地为Ningjing1的3.8和5.2mg/g，显著地为Zhendao11比那些降低(7.4和12.8mg/g，分别地)。根据在植物生长特征和CH4排放之间的关系，一个更强壮的根系统主要作出贡献到Ningjing1的更低的CH4排放，作为与Zhendao11相比。我们的结果证明超级米饭不仅在谷物生产率而且在CH4排放缓解有优点。收割的超级米饭的进一步的扩大将在中国提高米饭收益和还原剂温室气体排放。
