35尺一个单元,就是一条渠道两扇畦,渠道占地3尺,畦埂占地2尺,畦心占地15尺,一条渠道两扇畦共占地35尺。竖渠横浇,每扇畦再做成横畦埂,构成15尺见方的小方畦。这种渠畦结构的好处是:一、便于平整土地采取一埂二平三渠四畦五浇水的步骤,实现了地平畦平。效果很好。一埂:就是筑好边畦埂,按照35尺的尺码,两端树桩,标好线,用犁筑好埂边,保证做到埂直如线。二平:在两埂之间先横向找平,然后再纵向找成统一的坡降,顺水畦内由上往下找,
A unit of 35 feet means two channels of one channel. The channel covers an area of 3 feet and the 畦 埂 occupies 2 feet. The center of the channel occupies 15 feet. A channel occupies a total area of 35 feet. Vertical canal lateral pouring, each fan and then made horizontal 畦 埂, 15 square feet square 畦. The benefits of this drainage structure are: First, to facilitate the formation of the land to take a 埂 平 three drainage four 畦 five watering steps to achieve peace and harmony. good results. A 埂: is to build a border 畦 按, in accordance with the 35-foot size, both ends of the stump, marked a good line, with a plow to build 埂 edge, to ensure that 埂 straight line. Two flat: horizontal leveling between the first two, and then find a unified vertical gradient, Shun Shui within the top to find,
