休閑土壤
英文
fallow soils-
The changing procedure of soil water infiltration capacities is in keeping with second - degree polynomial change functions in cornfield, sesame field and fallow field and with quartic - degree polynomial change functions in wheat field in unfrozen phase, the changing process of soil water infiltration capacities suit second - degree polynomial change functions in various husbandry condition in frozen phase
在非凍結期，玉米地、芝麻地和休閑地的土壤水分入滲能力的變化過程符合二次多項式變化規律，小麥地的土壤水分入滲能力符合四次多項式變化規律；在凍結期，無論是哪種耕作條件土壤水分入滲能力符合二次多項式變化規律。In light of current using situation and drawing on the experience of many scholars researched methods and viewpoints, this thesis made com land, fallow land, orchard, grass land as experimental field in black soil region jlau, which carried out experiment by applying different amounts of n and p fertilization in corn field. by means of collecting the samples of rainfall runoff, erosion silt and surface layer soil before and after rainfall for one year nature precipitation in field, we study the effect of surface runoff on n and p nutrient and fertility degeneration. the results showed : ( l ) there are lots of factors which affect soil erosion and losses of n and p, in which rainfall and rainfall intensity were more important, while rainfall intensity is the most important meteorological phenomena factor
針對當前黑土利用現狀，本文借鑒眾多學者的研究方法和觀點，在吉林農大黑土區選擇利用方式不同的玉米地、休閑地、果園、草地，在玉米區進行了不同數量的施肥，通過野外試驗，採集一年自然降雨產流及泥沙樣品，同時採集降雨前後的耕層土壤樣品，研究了黑土區地表徑流對氮磷養分特徵及肥力退化的影響，結果表明：土壤侵蝕和氮磷的流失受諸多因素的影響，降雨量、降雨強度是重要因子，而降雨強度是影響農田地表徑流養分流失的最重要的氣象因子，特別是暴雨，暴雨徑流中氮磷濃度較平時高得多；隨作物生長，覆蓋度逐漸增加以及不同利用方式下表現的覆蓋度差異，氮磷流失都表現為顯著的差異。The results show that ( 1 ) the system of contour dams, contours and fallow had positive impact on water and soil losses than grass stripes and contour ditch. at the same time it was showed that contour dams, contours, fallow significantly reduced soil erosion and water loss, grass stripe and contour ditch had recorded reduction in water and soil losses although to a much less extent than above 3 farming systems. most of sediment was bed load in all the systems except in contour dams and contour fanning
研究的主要結論如下： 1 、運用坡面徑流小區法系統地研究了當地農業生產活動中不同農作措施下紅壤坡耕地水土流失特徵、土壤養分流失規律及形態特徵，結果表明： （ 1 ）同順坡農作措施相比：其它農作措施均具有明顯減輕水土流失的作用，等高土埂，等高農作、休閑處理控制水土流失的效果優於水平草帶和水平溝處理。A filed study on soil nutrient loss of different slope landuse types in the xiaolangdi gorges reservoir area was conducted under simulated rainfall
摘要通過野外模擬降雨試驗，分析了撂荒荒坡、林草間作、農林間作、造林林地和坡耕地翻耕種植玉米、坡耕地翻耕休閑6種利用方式下的土壤流失特徵。( 2 ) the losses of organic carbon, nitrogen, phosphorus and potassium were different in different farming systems. this losses of these elements according to respective farming systems was the following order : tradition > grass stripe > contour ditch > fallow > contour dam. compared with traditional fanning practices, others farming systems reduced losses of organic carbon, nitrogen, phosphorus and potassium and losses in contour dam, contour and fallow were much less than grass stripe and contour ditch
（ 2 ）不同農作措施徑流小區有機碳、氮、磷、鉀流失差異明顯，有機碳、氮、磷、鉀流失總量的順序為：順坡農作水平草帶水平溝休閑等高土埂，同順坡農作相比，其他農作措施均有減少有機碳、氮、磷、鉀流失的作用，以等高土埂、等高農作、休閑處理減少土壤有機碳、氮、磷、鉀流失的效果較好。In the northern wheat growing areas, most of the water used by the wheat crop falls before the growing season and the crop is grown mainly on stored moisture from fallowing
在南部小麥栽培區，大部分雨水分佈在4至10月份之間，這是小麥大致的生育期，盡管也有一些地區土壤水分是靠休閑時儲蓄的。The wide range in yields is due to the particular farming practices which include crop rotation and length of fallow and their effect on soil moisture levels
產量之間差異較大是由於各自不同的農藝措施，這包括作物輪作、休閑時間長短及它們對土壤水分的影響。分享友人
