近几十年来，由于在农村社区人口减少和老龄化后放弃了森林管理做法，竹子在日本扩大了分布。开发竹子生物质资源的有效利用是非常可取的。在这项研究中，我们测试了磨碎的竹子作为一种新型的有机覆盖材料在无农药水稻种植中的效果。具体地说，我们测试了有或没有经过冷藏/发酵处理的粉碎秸秆和叶片是否对水稻产量产生了不同的影响。采用塑料盆(0.31m~2)，采用随机区组设计，共设5个处理，5个重复：(1)对照，(2)发酵碎竹笋，(3)冷藏碎竹，(4)发酵碎竹叶，(5)冷藏碎竹叶。地面施竹子成功地抑制了最具优势的水生杂草--竹叶斑茅的盖度。无论竹器官来源或冷藏/发酵处理的差异，大多数磨碎竹处理的水稻分蘖数和土壤植物分析发育值都显着高于对照(相对于对照)。通过促进水稻植株生长和抑制水生杂草，四种碎竹处理的水稻产量是对照的1.76-2.06倍。追施竹粉对稻米品质的影响不明显。因此，使用磨碎的竹子覆盖在提高优质水稻产量方面具有相当大的潜力，至少在小规模上是这样。
Bamboos have expanded their distribution in Japan in recent decades due to the abandonment of forest management practices following depopulation and aging in rural communities. Developing effective uses for bamboo biomass resources is highly desirable. In this study, we tested the effectiveness of ground bamboo as a new organic mulching material for agrochemical-free rice farming. Specifically, we tested whether ground culms and leaves with or without refrigeration/fermentation treatments influenced rice production differently. Using plastic tubs (0.31 m2), we conducted a field experiment comprising five treatments with five replicates deployed in a randomized block design: (1) control, (2) fermented ground bamboo culm application, (3) refrigerated ground bamboo culm application, (4) fermented ground bamboo leaf application and (5) refrigerated ground bamboo leaf application. Ground bamboo application successfully suppressed the coverage of the most dominant aquatic weed,Monochoria vaginalis(Pontederiaceae). Tiller numbers and soil plant analysis development values of rice plants were significantly higher in most ground bamboo treatments (relative to controls) regardless of differences in bamboo organ source or refrigeration/fermentation treatment. Through enhancement of rice plant growth and suppression of aquatic weeds, rice yields were 1.76–2.06 times higher in the four ground bamboo treatments relative to controls. Application of ground bamboo did not noticeably reduce rice grain quality. Thus, the use of ground bamboo mulch has considerable potential in increasing the yield of high-quality rice, at least on a small scale.
