Rice-maize (R-M) cropping systems have emerged in recent years on 3.5 million hectares in Asia in response to the increasing demand from a rapidly expanding human population for rice and livestock pro...
Allelopathic effect of aquatic hull extract of rice (Oryza sativa L.) on growth of Silybum marianum and Echinochloa crus-galli
Allelopathy Echinochloa crus-galli Oryza sativa L Silybum marianum
2011/1/12
In this research, the allelopathy effect of rice hull extracts (Oryza sativa L.) on Silybum marianum and Echinochloa crus-galli was investigated. The water extracts were gotten from 13 cultivated rice...

Scarcity of water and N fertilizer are major constraints to rice production, particularly in developing countries where rainfed upland condition dominates. Improvement of genetic adaptability to inade...
Development of the V-furrow No-Till Direct Seeding of Rice Stabilization of Culture by Adopting the Winter-Puddling Seedbed Preparation
Growth and yield No-till direct seeding Rice Seedbed preparation Seedling emergence
2009/7/8
In Japan, no-till direct seeding of rice has been expected to reduce production cost, and thus many trials have been repeated. However, we pointed out that it has problems for practical use such as l...
CERES-Rice模型在中国主要水稻生态区的模拟及其检验
CERES-Rice模型 水稻生态区 模拟与检验
2007/12/28
本文利用水稻生长观测资料和气象资料，采用CERES-Rice模型在中国主要稻区开展应用研究，对水稻产量、开花期和生物量等的模拟能力进行了评价。所选试验站点分布在不同的水稻生态区，地跨北纬20º02´(海南海口)至北纬45º45´（黑龙江五常）。结果表明，在不同的水稻生态区，CERES-Rice模型模拟水稻开花期、每平方米粒数、单位产量及生物量的误差在合理...
