Nghiên cứu áp dụng hệ thống tưới tự động để nâng cao hiệu quả canh tác sầu riêng (Durio zibethinus L.) tại tỉnh Lâm Đồng

Abstract

The study aimed to evaluate the effectiveness of an automatic irrigation system equipped with sensors in the cultivation of durian (Durio zibethinus L.) in Phuoc Loc commune, Da Huoai district, Lam Dong province. The system was designed to adapt to the actual terrain conditions and the physiological requirements of the crop, featuring pressure-compensated sprinkler heads, soil moisture sensors, and a remote control system. The experiment was conducted on three-year-old Ri6 durian trees (Durio zibethinus L. cv. Ri6) employing two irrigation techniques: automatic and manual. The observed indicators included irrigation volume, soil moisture, growth parameters, flowering rate, fruit set, fruit retention rate, and the timely ripening rate of fruit. The results indicated that the automatic irrigation group, which was watered according to demand, had a higher flowering rate (68 compared with 53%), a higher average number of fruits per tree (7.2 compared with 1.3 fruits/tree), and a significantly enhanced timely ripening rate (92 compared with 35%). The results validated that the automated irrigation system enhanced both yield and fruit quality while also optimizing water consumption and decreasing labor expenses. These findings underscore the possibility of extensive implementation of intelligent irrigation systems in durian farming.
