1 换苗器(如图1) 结构:①手柄用4分管材制成; ②锥杆与手柄同径,是用低碳钢加工而成; ③手柄与锥杆成直角焊接,进苗缝在手柄上端。使用:将死苗拔出,在原苗木位置上将锥杆插入适当深度,然后旋转拔出,从进苗缝把补植的新苗根部放入手柄内,再用手柄作引导将苗木送入孔内,用土将孔封严,喷灌后新苗即能与苗床结合。特点:用换苗器解决了因苗木根深、株距小而不易补植的问题,从而提高了产苗量和苗床利用率。 2 杨树苗木扦插器(如图2)
1 for seedlings (Figure 1) Structure: ① handle with 4 tubes made of; ② tapered rod and handle with the same diameter, is made of mild steel; ③ handle and tapered rod at right angles to the weld into the seedling seams Upper handle. Use: The dead seedlings pulled out, in the original seedlings position the cone into the appropriate depth, and then pull out the pull, from the seedling into the replantation of new seedling roots into the handle, and then use the handle to guide the seedlings into the hole Inside, the hole will be sealed with soil, sprinkling seedlings that can be combined with the seedbed. Features: With the seedling changer to solve the root deep seedlings, plant spacing is not easy replanting problems, thereby increasing the amount of seedling production and seedbed utilization. 2 poplar seedlings cuttings (Figure 2)
