湖北省广水市农资公司曹宏农艺师经过几年的悉心钻研,成功探索出化肥插管渗施技术。现将该技术要点向农民朋友介绍如下。 插管制作 取长20～25厘米、直径2～3厘米、管壁厚3～5毫米的塑料管一根,将塑料管底部制成圆锥形(便于插入土壤中),在塑管四周(含下端圆锥体)均匀钻成直径为1～2毫米的小圆孔。塑管的顶口部用稍大的塑管制成罩盖(用农膜罩盖缠绑亦可),以防雨水淋入管内和防止化肥挥发。
After years of careful study, Cao Hong agronomist of agricultural materials company in Guangshui City, Hubei Province, successfully explored the technology of chemical fertilization and intubation infiltration. Now the technical points to farmers friends are as follows. Intubation take a length of 20 to 25 cm, diameter of 2 to 3 cm, the wall thickness of 3 to 5 mm a plastic tube, the plastic tube made of conical bottom (easy to insert into the soil), around the plastic pipe (including Lower cone) into a uniform diameter of 1 to 2 mm small round hole. The top of the plastic pipe with a slightly larger plastic cover made of plastic (covered with plastic sheeting may also be tied) to prevent rainwater poured into the tube and to prevent chemical volatilization.
