RESULTS OF RESEARCH AND TESTING OF THE SYSTEM FOR TREATMENT OF BANANA TREE, LEAVES AND TREE ROOT AFTER HARVEST

Currently in Vietnam, the treatment of banana stems, leaves and roots after each harvest and after the end of the exploitation cycle is carried out by manual labor or using excavators and bulldozers to collect and let them decompose naturally. Thus, the treatment cost is high and the decomposition time is long, creating pathogens to develop. If the excavator is not used to dig up all the roots, after 1-2 months, a large number of young banana plants will grow, hindering the preparation of the land for planting the new crop. The article introduces the results of research and testing of the Banana Stem, Leaf and Root Processing Machine System after harvest. The theoretical research results have calculated the cutting length of the discshaped Combine chopper when operating at a forward speed of 1.5km/h, PTO shaft speed of 540rpm is 23mm; The largest chip thickness of the Combine chopper when operating at a forward speed of 1.5km/h, PTO shaft speed of 540rpm, milling depth of 170mm is 24.48mm. The rate of banana trees growing above the ground at different milling depths is as follows: at depth of 150mm, within a 100m length, there are 8-11 trees growing; at depth of 170mm, there are 4-6 trees growing; at depth of 190mm, there are 3-4 trees growing.
