Timing is Crucial for Plug Seedling Substrate Testing [PDF]

open access: yesHortTechnology, 1997
Many plug seedling growers complain about the inadequacy of substrate testing as a measure of nutritional status because results are too variable. We conducted two experiments to test a model system of sampling substrate at a set time after fertilization. Petunias ( Petunia×hybrida Hort.

Soil Bin Studies on Plug and Finger-type Onion Seedling Transplanting Mechanisms [PDF]

open access: yes, 2018
A study was conducted to develop a plug- and finger-type onion seedling transplanting mechanisms in a soil bin and examine the effects of age of seedling and machine parameters (speed of operation, height of seedling drop, finger material) on plant ...

Study on the Impact Damage Characteristics of Transplanting Seedlings Based on Pressure Distribution Measurement System

open access: yesHorticulturae, 2022
Collision is one of the main causes of mechanical damage to the seedling during transplanting. To reveal the impact damage characteristics of plug seedlings, the kinetics equations of seedling collision were established based on Hertz’s contact theory ...

“Two‐steps” seed‐derived plugs as an effective propagation method for the establishment of Miscanthus in saline–alkaline soil

open access: yesGCB Bioenergy, 2021
Miscanthus, a perennial rhizomatous C4 grass, has emerged as a promising lignocellulosic crop. To avoid competition with food crops, marginal lands especially saline–alkaline soil are being recommended to grow Miscanthus across China.

Research on the End Effector and Optimal Motion Control Strategy for a Plug Seedling Transplanting Parallel Robot [PDF]

open access: yes, 2022
Due to the phenomenon of holes and inferior seedlings in trays, it is necessary to remove and replenish unqualified seedlings. The traditional operation is labor-intensive, and the degree of mechanization is low. This paper took broccoli seedlings as the

A Study on the Optimal Grasping Angle Algorithm for Plug Seedlings Based on Machine Vision

open access: yesAgronomy, 2023
During the replanting operation of a seedling tray, the end-effector needs to repeatedly grab the qualified plug seedlings in the supply tray and release them to the target tray for replanting, and in the process of grasping, the end-effector may cause ...
