冬,春塑料大硼蔬菜栽培,在棚内地面均匀地撤施一层草木灰,可以有效地降低棚内湿度,提高地温,补充钾肥,是冬、春大棚蔬菜栽培的有效防病防虫,提质增产措施。其具体的好处是: 1、降温防病虫大棚蔬菜栽培,湿度过高,容易使蔬菜发生严重的病虫危害。干草木灰具有很强的吸湿性能、撤施于大棚内地面后,可有效地吸收棚室内的水分,降低棚室内的湿度,大大降低病虫害的发生率、减轻病虫危害,提高大棚蔬菜的品质和产量。2、保温增动力因为表面黑色的物体辐射吸收热的能力强,草木灰呈灰黑色,具有较强的吸热能力,均
Winter and spring plastic boron vegetable cultivation, uniform removal of a layer of ash in the shed floor, can effectively reduce the shed humidity, increase ground temperature, add potash, winter and spring greenhouse vegetable cultivation effective disease prevention and pest control, quality Increase production measures. The specific benefits are: 1, greenhouse pest control greenhouse cultivation, high humidity, easy to vegetable serious pest damage. The hay ash has a strong hygroscopic property. After being removed in the greenhouse, the moisture inside the greenhouse can be effectively absorbed, the humidity in the greenhouse can be reduced, the incidence of pests and diseases can be greatly reduced, the pests and diseases can be lessened, the quality of greenhouse vegetables can be improved, Yield. 2, the thermal insulation by the surface of the black body radiation ability to absorb heat, ash is gray-black, with a strong endothermic capacity, are
