달랏의 12구역 구릉 뒤편에는 문자 그대로 혁신적인 무언가가 자라고 있습니다. 관광객들이 전통 딸기 농장으로 몰려드는 동안, 우주 정거장처럼 보이는 기후 제어 온실에서 조용한 농업 혁명이 싹트고 있습니다.
민 아저씨를 만나보세요, 아라비카 커피 농장을 떠나 무토양 상추 농장으로 전향한 전직 커피 농부입니다. 그는 영양분이 풍부한 물에 떠 있는 깨끗한 버터헤드 상추 줄기를 가리키며 웃으며 말합니다. "사람들은 내가 미쳤다고 했죠," "지금은 조카가 우리 사업을 확장하려고 농업공학을 공부하고 있어요."
이 수경재배 상추 농장들은 달랏의 농업 정체성을 새롭게 바꾸고 있습니다. 전통 농업보다 90% 적은 물을 사용하고 단 30일 만에 수확 가능한 채소를 생산하며, 호치민시부터 하노이까지 고급 레스토랑에 공급합니다.
K'Ho 공동체는 이 기술을 받아들여 전통 고원 농업 지혜와 최첨단 수경재배를 결합했습니다. 많은 농장에서는 방문객들이 일본 미즈나, 이탈리아 루꼴라, 무지개 근대 등 달랏의 완벽한 연중 기후에서 자라는 상추 품종을 볼 수 있는 **"미래 농업 투어"**를 제공합니다.
이것이 특별한 이유는? 도시의 수직 농장과 달리, 달랏의 고원 위치는 자연 냉각을 제공해 에너지 비용을 40% 절감합니다. 결과는? 베트남에서 가장 비싼 상추 중 일부—킬로그램당 80,000 VND에 판매되지만, 가장 신선한 상추입니다.
dalat.app 방문객들은 점점 더 이 농업 투어를 예약하며 전통 꽃밭과 베트남 농업의 미래를 엿볼 수 있습니다. 이는 달랏이 단순히 농업 유산을 보존하는 것이 아니라 혁신하고 있음을 증명합니다.
