印度旁遮普地区低山区,冬小麦生长季节降雨量极少,干旱常常造成小麦减产。要保证种子正常发芽,就必须在播种层保持充足的水分。过去有人报导,残留在地表的枝叶,可保持土壤贮存的水分,尤其可以提高土壤表层的含水量。由于覆盖地表,使播层水分发生微小的变化,就能对小麦增产起很大作用。 In low-mountain areas of Punjab, India, there is very little rainfall during winter wheat growing season and drought often leads to a decrease in wheat yield. To ensure the normal seed germination, we must maintain adequate moisture in the seeding layer. In the past, it was reported that the leaves and leaves that remain on the ground maintain the moisture stored in the soil, and in particular, increase the water content of the soil surface. Covering the surface, so that the sowing of small changes in water, wheat yield will be able to play a significant role.
