Permanent Raised Beds(PRB),which is an agricultural technology with the features of conservation tillage,controlled traffic,ridge-tillage and furrow irrigation,can adopt ridge-loosing technique to solve the problem of weak water infiltration ability of wide ridge.

Effects of ridge width and planting density on corn yields in rainwater-harvesting system with plastic film mulching on ridge

As a cultivation and irrigation method for field crops,wide ridge and furrow irrigation have already been paid attention gradually.

On the basis of comparson between the "broad row and unmoving vine" planting model and traditional planting model,the results showed that there were many superiorities of this planting model,such as increasing marketable yield(The total yield of the "broad and unmoving vine" planting model is 97.
