Effect of Furrow Opener for No-till Wheat Planter on Seed Zone Properties and Root Establishment
The furrow openers are one of the key parts of the no-till planters, its structure can effect the soil disturbance and the root growth. Experiments were conducted in Daxing district of Beijing city containing a loam soil to assess the effect of the soil disturbance, the wheat root, the plant weight and the yield of three furrow openers. The furrow openers compared were the tine opener, the single- disc opener and the rotary opener. The result showed that different furrow openers can form different the seed groove, so it can effect the seed germination, the root growth and the yield. The rotary opener can form the loose groove, compared to the tine opener and the single-disc opener, gave the maximum the counts of the adventitious root and tillering counts, but the soil disturbance is the biggest, up to 40- 60％, so the fuel consumption is the highest; The minimum yield and the counts of the adventitious root and tillering counts were obtained with single-disc opener, but the soil disturbance is the lowest, just about 10-15％. The coefficient of the tine opener was obtained between the others furrow openers. So we should design and elect the suitable furrow openers which can form shatter sub-surface seedbed and minimum soil disturbance.
