条田和台田的作用1.有利于排除地表水和降低地下水位。密布田间的条(台)田沟容水量很大,再加上干、支渠的配套,可迅速排泄地表积水,加快地下水位的下降速度(见下图),减少作物受淹时间,保证土壤具有良好的通气性。 Field and Taichian role 1 is conducive to the exclusion of surface water and lower groundwater levels. In the dense field, a large amount of water can be drained in the ditch (table). Coupled with dry and branch channels, the surface water can be excreted rapidly to speed up the descent of the groundwater table (see below), reduce the flooding time of the crops, and ensure that the soil Has good ventilation.
