稻田渗漏与稻根生长的试验

本文根据珠江三角洲沙围田地区,土质粘重,“四水”过剩,影响水稻根、稻叶早衰,限制稻谷产量的实际问题,对稻田渗漏与稻根生长的关系进行了六年的试验研究。提出了确定稻田适宜渗漏量的指标及其生物学依据,对我国南方类似条件的稻田,均有参考价值。

Experiment ON Leakage OF Rice-field AND Growth OF Rice-roots

Shaweitian Area, located in the Delia of the Pearl River, is heavily-clay texturedand has a surplus of four waters-the atmospheric precipitation, surface water, soilwater and ground waler. The growth of rice-roots is thus affected, early-withering of rice-leaves is caused and rice-yield is limited. Experiments studying the relationship between field leadage and root growth have been conducted for 6 years to solve these problems. This paper puts forward some norms suitable for the determination of rice-field leakage and the biological basis concerned. So a good example is procided here fcr the rice production under similar conditions in, the south of the country,
