Quality of orchard protection with different value of liquid
2004
Bugarin, R.M.
In this study the aim was on researching quality of treating orchard with sprayers which works with different value of liquid. It was research standard sprayer using standard, large, middle and small value of liquid with different speed of agregate, air capacity of fan and nozzle type. The aim was found the best liquid value for treating, after special analysis of quality of treating some grass zone. On the same time it was some losses as result of air and land drift which was connected with value of liquid and work term. In work are given results laboratory vertical deposit of liquid using especially equipage for measurement. It was also given results of air speed in some zone of apple tree on the place and in move. Answer on our postulate about quality of orchard protection, base on results of our research is: Quality and care work with middle (500-1000 l/ha) and small liquid value (200-500 l/ha) compare with standard value (1000 - 1500 l/ha) will give us quality of treating without different on standard which will be important. Middle and small value of liquid, give us large decrease of energy which means better economic results with better protection of our environment. Determinate quality of treating was made with especially water-sensitive plate. Arrangement of measuring plate was made very accurately in laboratory by scaner and computers.
