摘 要:相比于傳統的種植田地方式,大棚是個封閉的農業生產設施。自然降雨不能被直接利用,大棚內農作物需要的水分完全依靠人工灌溉措施來保證。而傳統的灌溉方式效率低、人工成本高,亟需向自動化、智能化轉變。隨著科學技術的發展,尤其是物聯網技術在農業生產中的逐步應用,智能灌溉已經成為大棚灌溉的發展趨向。本文主要探討了基于GPRS和LORA的大棚智能灌溉系統的探索與設計。

Abstract:Greenhouse is a closed agriculture facilities compared with the traditional planting fields. The requisite moisture for crops in greenhouse completely depends on artificial irrigation,because the natural rainfall can’t be absorbed by the crops directly. As the efficiency of traditional irrigation is very low and the cost of labor is very high,so the traditional irrigation urgently needed to be more automated and more intelligent. With the development of science and technology,especially the internet of things has been using in agricultural production gradually,the intelligent irrigation has been a trend in the developing of greenhouse irrigation. The purpose of this study was to explore and design a greenhouse intelligent irrigation system based on GPRS and LORA.

近些年來,我國大棚種植面積不斷提高。大棚農業是根據農作物生長發育需求,通過人工調節改變局部氣象環境,為農作物的生長發育提供適宜的環境條件,一定程度上擺脫了對自然因素依賴的新型農業。它改變了傳統農業的種植生產模式,打破了農作物生長在地域和時空上的界限,推動了現代農業的發展進程。但由于大棚是個相對封閉的農業生產設施,大棚內作物不能直接吸收自然降雨,所需要的水分完全依靠人工灌溉。而農作物的生長的土壤需要保持一定程度的濕度,并且不同的生長時期對水分的需求往往不同。人們通常是通過觀察土壤濕度情況、農作物生長狀態并結合自己在種植中的經驗,對農作物進行灌溉。這種人工灌溉方式不能及時或者準確地控制灌溉水量,因此不能滿足農作物的最佳適宜濕度,同時也會對水資源造成浪費。
