輕質壤土 的英文怎麼說
中文拼音 [qīngzhírǎngtǔ]
輕質壤土
英文
light loam-
Soil is the base of agriculture production, the key measure to prevent water and soil loss is to conserve soil, but most soil nutrient is lost with the sediment loss, and serious water and soil loss make the soil thickness degrease, the soil nutrient be deficient and lean, the land quality degrade and the yield of plant decrease, all this results is going to threaten the people ' s transplanting and the agriculture sustainable development, and restrict the economy development of three gorges regions
同時，土壤是農業生產的根本，治理水土流失的關鍵是要保住土壤，而土壤養分絕大部分是隨著泥沙流失的，嚴重的水土流失造成土層淺簿、養分貧瘠，土地質量退化，產量下降，對三峽庫區移民工作和農業可持續發展造成嚴重威脅，制約三峽庫區經濟發展。因此進行三峽庫區坡耕地土壤侵蝕機理研究，探索減輕坡耕地土壤流失的方法措施，具有全局性的重大意義。The soil was brown soil in type and light loam in texture
供試土類為褐土，質地為輕壤。Effect of base to dressing ratio of nitrogen fertilizer on wheat yield and quality in light - loamy chao soil
輕壤質潮土氮肥基追比對小麥產量與品質的影響Abstract : based on analysis of status and structure of land resources in tengxian, it is pointed out that its limited conditions are such as less and bad land and problemes are such as unreasonable texture and no care on land use, and the suggestions and countermeasures correspondly by the idea of sustainable development such as land improving and land use control and population control have been given
文摘:在分析藤縣土地資源現狀的基礎上，指出了不利於土地持續利用和開發的地少質差、土地利用結構不合理及重用輕養等主要問題，並根據可持續發展的思想提出了改良土壤、用途管制、控制人口等對策。The results indicated that as the intensity of sward cleavage increased, elymus nutans and other plants that had high requirements in soil aeration and resource space presented an increased competitive edge and the species that had low requirements in soil aeration and resource space presented an opposite picture ; low - intensity sward cleavage could help increase species diversity to a certain extent, but the diversity index appeared to decline as a whole as the cleavage intensity increased ; the effects of sward cleavage on functional groups of the vegetations showed in such manner as e. nutans - represented grasses increased in their composition with the intensity of sward cleavage raised, and sedges and forbs decreased in their compositions with the intensity of sward cleavage raised ; sward cleavage showed a significant improving effect on primary productivity of the meadows and was capable of increasing the proportion of quality - grass biomass to the total plant biomass ; sward cleavage could be independently employed as an effective measure to rehabilitate and improve alpine - meadow grasslands and thus played a basic and key role in the technical combination aiming at establishing hay fields characterized by e. nutans
結果表明：垂穗披堿草等對土壤通透性和資源空間要求較高的物種，競爭力隨劃破強度的增加而上升，而對土壤通透性和資源空間要求相對較低的物種則相反；輕度劃破干擾對提高物種豐富度具有一定的促進作用，但多樣性指數則總體上表現為隨劃破強度的增加而呈下降的趨勢；劃破干擾對植被功能群的影響表現為以垂穗披堿草為代表的禾草類組分隨干擾強度的增加而顯著上升，莎草類和雜類草組分隨干擾強度的增加而顯著下降；劃破干擾對草地初級生產力的提升具有顯著的促進作用，且可顯著增加植物總量中優質牧草的比重；劃破干擾可獨立作為高寒草甸類草地恢復與改良的有效措施，在定向培育垂穗披堿草型割草場的技術組合中具有核心和基礎性的地位。Since the majority of soils planted to oil palms in thailand are light textured, with a low inherent k status, the scope for improving oil palm yields by better balanced nutrition with potassium is substantial
在泰國，由於油棕櫚主要種植在輕質土壤上，土壤含鉀量低，所以通過包括鉀在內的平衡施肥來提高油棕櫚的產量潛力很大。Because of this, the author researches the theory and method of the geographical equilibrium point of the soil potassium based on the study of others with the case of aquent in xiongxian county of hebei provience. 1
鑒於此，在前人研究的基礎上，以河北省雄縣輕壤質潮土為例，就土壤鉀素地理平衡點的概念、特徵及測算方法進行了探討。分享友人
