义县九道岭乡平坊子村科技示范户陶国秋承包的坡耕地,由于干旱瘠薄,玉米单产只有400斤左右。去年秋天,他去山西学习抗旱夺丰收经验,回来后在自家的坡耕地上挖3亩抗旱丰产沟,今春种植锦单五号玉米,他的作法是: 1. 挖沟 秋收后,在坡耕地上横向挖沟,沟宽2.2尺,深1.2尺,上下沟间距为2.2尺。先将地表熟土挖取6寸深,取土放在沟的—侧。在沟里再向下挖6寸深,将生土放在沟的另一侧。然后,把沟内土再翻6寸深,松土不取出。将沟边放的生土就地搂平,压一遍磙子,形成高于沟口的土台。 2. 施肥 把沤制好的秸秆肥或其它农家肥与过磷酸钙混拌(每亩用秸秆肥3,000～5,000斤,其它农家肥8,000斤左右,过磷酸钙100斤),施到沟里后与松土拌匀,然后将沟边堆放的表层熟土推入沟内并搂平。 3. 种植 于4月末在沟内种植玉米,每沟种2行,株行距为1×1尺。按纯面积算,每亩6,000株。播种时,随种下口肥,施用常规量。丰产沟之间的土台上种植早熟系草木樨,4月末至5月初播种,7月初压青。准备种两年后,依照前法,将沟变成台,将台变成沟,继续实行粮草间种。
Yixian Jiudingling Township Pingfangzi village technology demonstration households Tao Guoqiu contract slope farmland, due to dry infertility, corn yields only 400 pounds or so. Last autumn, he went to Shanxi to learn drought-harvest experience and came back to dig 3 hectares of drought-resistant ditches on his sloping farmland. In the spring, he cultivated Jindan No. 5 corn. His practice is as follows: 1. After digging ditch autumn harvest, On the horizontal trenching, groove width of 2.2 feet, 1.2 feet deep, up and down the trench spacing of 2.2 feet. Dig the surface of the earth first 6-inch deep soil, soil placed in the ditch - side. Dug down in the ditch 6 inches deep, will be born on the other side of the trench. Then, turn the furrow 6 inches deep, loose soil is not removed. Gully put place on earth to hug flat, press it again prickly heat, forming a soil station above Mizoguchi. 2. Fertilization to make a good straw fertilizer or other manure mixed with superphosphate (straw mu fertilizer per mu 3,000 to 5,000 pounds, about 8,000 kilograms of other manure, superphosphate 100 pounds), after the ditch into the ditch Mix well with loose soil, and then push the surface of the surface of the trench to push the furrow and hug Ping. 3. Planting At the end of April planting corn in the ditch, each row 2 lines, spacing of 1 × 1 feet. Calculated as pure area, 6,000 plants per mu. Sowing, with the kinds of fat under the mouth, the application of conventional volume. Dachang Ditch between the soil planted early maturing plants Mucuna, from late April to early May sowing, early July green pressure. After two years of preparations, according to the former law, the ditch will be turned into a taiwan, the taiwanese ditch will become a ditch, and the forage species will continue to be implemented.
