摘要

为了提高吊篮式移栽机构喂苗准确率和降低苗钵质量损失,利用接触力学建立苗钵最大变形量的方程,并用高速摄像观察番茄穴盘苗与栽植器的碰撞运动,得出栽植器的角速度、接苗角和番茄穴盘苗株高是影响喂苗准确率和苗钵质量损失的主要因素.在移栽频率为45和50株·min-1时,以接苗角和番茄穴盘苗株高为因素进行正交试验,用综合评分法得出接苗角取60°和80°,番茄穴盘苗株高取12和16 cm时,试验结果的综合评分较高.田间移栽试验表明,试验结果与正交试验基本一致,移栽频率为45～50株·min-1,接苗角取60°,番茄穴盘苗株高小于16 cm时,有利于提高喂苗准确率和降低苗钵质量损失.

Abstract

To improve the feeding accuracy of basket transplanter and reduce the damage rate of root lump,the maximum deformation equation of root lump was established by contact mechanics, and the collision movement between tomato plug seedling and transplanter was observed by high speed camera. The results show that angular velocity, seedling angle of planting device and height of tomato plug seedling are the main impact factors on feeding accuracy and weight loss of root lump. When the transplantation frequencies are 45 plants·min-1 and 50 plants·min-1, the orthogonal test is carried out with seedling angle and height of tomato plug seedling as factors to show that the overall rating of test result is good with seedling angles of 60°and 80°and heights of tomato plug seedling of 12 cm and 16 cm by the comprehensive score method. The field transplanting experiment illuminates that the test results are basically consistent with the orthogonal test. The feeding accuracy can be improved with reduced weight loss of root lump when the transplantation frequency is from 45 to 50 plants·min-1 with seeding angle of 60°and tomato plug seedling height less than 16 cm.
