| Abstract: |
| Based on the technology of double ridges whole film rainfall harvesting cultivation for corn on upland,the corn no-till planting mode of double ridge mulching "one film used for two year" on upland was studied.The results showed that compared with the conventional film mulching cultivation,this technology had better agronomical characters,increased corn yield by 956.1 kg/hm2(16.31%),and the soil water content of early period was increased.In comparison with the double ridges whole film rainfall harvesting cultivation and the conventional film mulching cultivation,this technology enhanced seeding rate by 2.58% and 14.5%,respectively;reduced investment by 1 350 yuan/hm2 and 1 860 yuan/hm2,respectively;increased net profit by 703.9 yuan/hm2 and 3 055.1 yuan/hm2,respectively. |
