当前,我国林业苗圃育苗所需的种子正向良种化、基地化方向发展,大部分都需从种子园、人工母树林采集。针对这一情况,我们自行研制了一种新的采种工具——采种抓(图1)。此工具总重量1公斤,造价2元,地面采种高度可达6~8米。一、操作方法①举:用双手拿着竹杆把采种抓举起。②对:把抓果齿的开口对准所采集的果枝或较大果柄的基部。③拉:用一只手往下拉操纵绳使两片抓果齿合拢。④拽:用双手同时向下拽动操纵绳和竹
At present, the seeds needed for nursery nursery in China are being improved in seed quality and base development, most of which need to be collected from seed orchard trees and artificial mother trees. In response to this situation, we have developed a new kind of seed-collecting tool - Seeding (Figure 1). The total weight of this tool 1 kg, cost 2 yuan, the height of the ground seed up to 6 to 8 meters. First, the operation ① lift: holding the bamboo with both hands to seize the seeds raises. ② right: the opening to catch the teeth of the fruit branch or larger fruit stem base. ③ pull: pull down the control rope with one hand to grab two pieces of fruit closed. ④ Drag: drag both hands down the rope and bamboo with both hands
