28405 - Machinery for Ornamental Green

Learning outcomes

At the end of the course the student acquires a basic knowledge of the main agricultural machinery and their use in the management of green areas. In particular, the student must be able to evaluate and choose the most suitable machines and techniques for the maintenance and restoration of public and ornamental green areas.

Course contents

3. qw

Prerequisites:

The student who accesses this teaching must be holding sufficient preparation in the fundamentals of mathematics acquired in the first year of studies.

Content of teaching unit 1:

1. Internal combustion engines, tractors and power cultivators (6h)

a. Functional and constructive characteristics of diesel engines and gasoline engines.

b. Performance energy.

c. Characteristic curves of the engine (power, torque and specific fuel consumption).

d. Construction of wheeled and crawler tractors and cultivators.

e. Connecting and drive tools.

f. Dynamic weighting and grip.

g. Safety and side tilting.

h. Types most commonly used for the treatment of ornamental plants.

At the end of the learning unit the student knows the engines and the traction units used for ornamental green and knows how to choose independently the types of machines more appropriate to different uses.

2. Machines for soil tillage and sowing (6h)

a. Purpose and techniques of soil tillage.

b. Description of tools for soil tillage.

c. Description of mechanical seeders (broadcasters, by gravity, rows) and hydroseeding.

d. Types most commonly used for the treatment of ornamental plants.

e. Operational characteristics and productivity of the machines mentioned.

At the end of the learning unit the student knows tools for tillage and seeding. he knows the different performance and functionality of the machines to make appropriate choices.

3. Machines for the distribution of fertilizers and pesticides (6h)

a. Physical and mechanical properties of mineral and organic fertilizers.

b. Description of manure and compost spreaders.

c. Description of gravity flow and centrifugal fertilizer spreaders.

d. Operation of sprayers machines (mechanical, pneumatic and centrifugal).

e. sizes of spray and coverage.

f. Sprayer machines for the distribution of herbicides.

g. Types most commonly used for the treatment of ornamental plants.

h. Operational characteristics and productivity of the machines mentioned.

At the end of the learning unit the student knows the equipment for distribution of fertilizer and pesticides. He knows to calibrate the equipment properly to get the best agronomic performance and the maximum respect for the environment.

Contents of pratical activities:

the topics covered in classroom will be integrated with external visits or laboratory activities (12 h). These will deal with aspects of the use and management of machines for ornamental plants, the calibration of sprayers, the calculation of operating cost.

Contents of teaching unit 2:

1. Introduction to green maintenance mechanization (2 h).

2. Agricultural machines for turf. Preparatory operations. Sowing and transplantation. Cutting devices with horizontal blades and helicoidal blades. Criteria for choosing a cutting machine (8 h).

3. Maintenance operations on turf. Defelting and aeration (4 h).

4. Grassy carpets for sport (3 h).

5. Machinery for ornamental trees and tree-lined roads (3 h).

6. Machinery for the treatment of urban waste. Chippers (3 h).

7. Machine operators safety. Problems related to noise and mechanical vibrations (4 h).

8. Machinery for the management of spontaneous flora on urban territory (3 h).

Readings/Bibliography

Material provided by the teachers and lesson notes.

For further study is recommended:

P. Piccarolo, "Creating and green care", Calderini Edagricole.

Teaching methods

Hall lessons and direct vision of machines.

Assessment methods

The knowledge taught in this course are evaluated through an final oral exam.
Generally this evaluation takes about 20/30 minutes in which they are asked 3-4 argoments.

This course is part of the integrated course "irrigation and drainage systems and machinery for the green." Therefore, the final evaluation of the student takes into account the level of acquired knowledge and skills relating to the contents of the entire integrated course.

Teaching tools

Copies of the visual material shown during the lessons and technical support from machinery factories.
