《天工开物·上篇·乃粒》
播撒稻种时，如果田里积水过深，稻种没有来得及沉下，这时猛然刮起了狂风，谷种就会堆积在秧田的一个角落，这是第二种灾害。
凡稻撒种时，或水浮数寸，其谷未即沉下，骤发狂风，堆积一隅，此二灾也。
When sowing the seeds, if the water in the field is too deep, the seeds will not sink down in time. If a strong wind suddenly blows, the seeds will accumulate in one corner of the field, which is the second kind of disaster.
