fertigation n.滴灌施肥。

fertile
When fertilizer was added as fertigation , the recovery of nitrogen fertilizer was high as 73 . 55 % , with the 110 . 44 % of increasing rate compared to traditional fertilization way ; and corresponding increasing rate in dry weight of shoot and grain yield and water use efficiency were 49 . 55 % , 67 . 57 % , 109 . 20 % , respectively 滴灌施肥與澆灌施肥相比，水分利用效率增加幅度為109 . 20 % 。肥料氮素利用率達73 . 55 % ，增加幅度為110 . 44 % 。可見，滴灌施肥可以明顯地提高水分和肥料氮素的利用率。
The content of mineral nitrogen content ( nh4 + - n + no3 - n ) decreased during the incubation period after applying nh4 + - n fertilizer and urea . it maybe relates to the nh4 + - n fixation , volatilization , and its nitrification . ( 4 ) fertigation by drip irrigation increased the n uptake and accumulation of dry matter of summer maize , and improved the activity of crop photosynthesis 與滴灌施用硝態氮肥相比，施用銨態氮肥和尿素后在培養期間土壤礦質態氮( n03一n + nh獷一n )的含量有降低的趨勢，降低的原因可能與nh4 +一n在土壤中的固定、揮發及硝化等過程有關。
However , the movement and transformation of n in soil under fertigation remains unclear . the methods of simulation experiment and culture experiment were used to study the movement and transformation of n in soil under fertigation by drip irrigation . the main experimental results were shown as folio wings : ( 1 ) the water infiltration under drop irrigation is a point infiltration ; and the soil moisture in vertical and horizontal directions was increased with the irrigation time , and the movement rate were decreased with the irrigation time 本研究采用室內模擬試驗和生物培養試驗相結合的方法，研究了在滴灌施肥條件下，化學氮肥施入土壤后的遷移、轉化規律以及對作物生長的效應，獲得了以下主要結論： ( 1 )滴灌條件下水分以點源入滲土壤，水平和垂向的濕潤鋒均隨入滲時間的增加而逐漸變大，在入滲開始階段濕潤鋒的推進速率較大，隨入滲時間的延長，濕潤鋒的推進速率逐漸變慢。
We also use polynomial function to model the soil moisture under drip irrigation ; and the function will be useful for design the drip irrigation system and fertigation system . ( 2 ) the amount water added and the way of supplying water and fertilizer were two key important factors to affect the movement , transformation , and leach of urea - n in soil 比較了不同模型擬合的滴灌條件下土壤濕潤鋒的動態變化，認為多項式模型的擬合程度較好；同時建立了土壤濕潤體水分含量( y )與徑向距離( l ) 、垂向距離( h ) 、實驗時間( t )之間的經驗關系式。
Adding fertilizers through the irrigation water ( i . e . fertigation ) is one of common ways of fertilization . however , the uneven distribution and leachings of nutrients and induced crop damage are the common problems for the traditional way of fertigation 灌溉施肥是生產中經常采用的一種水肥調控技術，但施肥不勻，養分流失，容易引起作物灼燒等，是傳統的灌溉施肥方法常常遇到的問題。
From these products came the introduction of many plastic products useful to high - yield agriculture such as plastic films , mulches , drip - irrigation tubing , pipes , fertigation equipment , filters , fittings and connectors , and row covers 由這些產品衍生出許多對高產農業有用的塑料產品，如塑料薄膜、塑料覆蓋料、滴灌塑料管道、輸水管道、灌溉施肥設備、過濾器、配件和接頭以及行覆蓋物。
9 . a gravity sprinkler fertigation device was developed and has been used in practice . it has been found more economical and effective in improving yield in comparison with manual fertilization and airplane application 同時，對噴灌條件下冬小麥、春小麥、油菜三種作物的試驗區與大田噴灌區、常規地面灌區，進行了產量與節水量的比較分析，得摘要出噴灌節水增產效果顯著。
Fertigation has become increasingly popular across the united states as water costs rise and issues related to the environment dictate more precise control of both irrigation water and fertilizer , especially nitrogen 隨著灌水費用的提高和環境上要求更精確地控制灌水量和施肥量尤其是氮肥，在美國灌溉施肥越來越普遍。
Fertigation by drip irrigation as an advanced technology to control the supply of water and nutrients has been applied by other countries in recent years 滴灌施肥作為一種先進的水分調控技術，近年來國外已開始廣泛采用，但對滴灌施肥條件下肥料養分在土壤中遷移轉化規律的了解尚十分有限。
Know the requirements for flushing the irrigation system after fertigation . this may take 10 to 15 minutes . also run clean water through the injection meter , discharge hose and check valve 灌溉施肥后需要沖洗灌溉系統，這也許需要10 ~ 15分鐘，用潔凈水沖洗注射器、拆掉澆水軟管和止固閥。
One of these technologies is fertigation , which is the direct application of water and nutrients to plants through a drip irrigation system 描述:文中介紹的一種灌溉技術叫做施肥灌溉，通過滴流灌溉系統把水和養分供給作物。
Know how much water is needed to refill the root zone during irrigation and plan fertigation accordingly 要了解在灌溉時灌滿根區需要多少水，并據此來制定灌溉施肥計劃。
Water quality is a key component of successful fertigation and necessitates careful attention 水質是灌溉施肥成功的關鍵方面，必須予以重視。
Application of automatic control technology in greenhouse fertigation system 自動控制技術在溫室灌溉施肥系統中的應用
