Effect of three furrow openers for no-till wheat seeder on crop growth performance

The structure of furrow opener can affect the power consumption and the wheat early growth. To overcome those problems, three furrow openers, which include the tine opener, the single-disc opener and the rotary opener were studied in the field in Beijing. The soil disturbance, the wheat early growth and the yield were measured and analyzed. The results showed that the yield of different furrow openers were not different statistically(p=0.05), but the different furrow openers could form different seedbed, so it can affect the seed germination, the wheat early growth. The rotary opener can form the loose groove, compared with the tine opener and the single-disc opener, the counts of the adventitious root are the most, but the soil disturbance is bigger, up to 40%～60%, so the power consumption is the highest; The lowest counts of the adventitious root and single plant weight occurred on the condition of single-disc opener, but the soil disturbance is the lowest, with about 10%～50%. So the different furrow openers can adapt to the different areas, people should design and select the suitable furrow openers based on the local characteristics of conservation tillage.
