官庄乡谭村张补生在低产田上做文章,1989年在自己耕种的1亩河滩地上,采用地膜覆盖技术种植甘薯,亩产达4000公斤。往年在河滩地上,他主要种植豆子,亩产仅25公斤左右。他首先针对河滩地土壤贫瘠的特点,增加了肥料投入,亩施农家肥4000公斤,磷肥50公斤,碳铵25公斤,草木灰50公斤。通过犁开沟条施,增加肥效。其次,针对河滩地耕作粗放的特点,应用地膜覆盖技术精耕细作,科学管理。在秋深耕的基础上进行早春耙耱,并春烧一次。4月中旬及早整地覆膜,控制水分蒸发。采用高垄覆盖的种植形式,将地膜覆于垄上,垄宽67厘
Guanzhuang Township Tan Bu Zhang Anson made an issue in the low-yielding fields, in 1989 he cultivated 1 mu of flood land, the use of plastic film mulching cultivation of sweet potato, mu up to 4000 kg. In previous years in the floodplain, he mainly grows beans, only about 25 kg per mu. He first aimed at the characteristics of poor soil in floodplains, increasing the input of fertilizers, mu of farmhouse fertilizer 4000kg, phosphate 50kg, ammonium bicarbonate 25kg, ash 50kg. Open plow trenches to increase fertilizer efficiency. Secondly, in view of the extensive characteristics of riverbank tillage, the technology of plastic film mulching is intensively cultivated and scientifically managed. On the basis of autumn deep plowing rake 早 early spring, and spring burn time. Early April mid-term plastic film, control of water evaporation. Covering the cultivation of high ridge form, the film covered in the ridge, ridge width 67%
