No matter hybrid rice or conventional rice varieties, erect and semi - erect panicle rice varieties were suitable for equal row spacing cultivation for intercepting mare light at canopy, while curved - panicle rice varieties were for wide - narrow row spacing cultivation for improving light intensities of middle and lower layer leaves
但不同類型品種適宜的栽培方式不同：雜交稻適宜插單苗，而常規稻適宜插3苗；不論是雜交稻還是常規稻，直立穗型和半直立穗型品種適宜等行距栽培以減少群體漏光，彎曲穗型品種適宜寬窄行栽培以改善中下層葉片的光照條件。 -
Heat fluxes estimated from radiative temperature by this model is more accurate than other regular corrective methods. two - layer model has been proposed for many years but was difficult to apply in remote sensing because component temperature were unavailable in traditional thermal sensors. a new airborne multi - angular thermal sensor system and retrieved soil and canopy temperatures were used to solve two - layer model, and the simulated heat fluxes show much better accuracy than the results from one - layer model especially above dry surfaces
雙層模型雖然提出很多年了，但在應用中一直存在信息不足，求解困難的問題，本文用最新多角度熱紅外遙感數據? ? ? amtis系統反演的組分溫度，首次實現了雙層模型在遙感中的應用，結果表明，在輸入參數精度相近的情況下，雙層模型模擬的通量誤差遠小於單層模型，尤其在土壤乾旱，表面溫度較高的地表，雙層模型的理論優勢在計算中表現得更加突出。 -
At first, the relations between vegetation structures and their controlling soil erosion are discussed. the results show that magnitude of plant community coverage or canopy closure is n ' t certainly the adequate condition of an anti - erosive effective community because the community function of soil and water conservation is related to height of coverage layer as well as community coverage or canopy closure
首先，討論了植被結構與其防止土壤侵蝕作用的關系，結果表明，植被蓋度或郁閉度的大小並不一定就是防蝕有效植被的充分條件，植被保持水土功能還與覆蓋層的高度密切相關，覆蓋層高度大並不有利於植被保持水土。 -
Root distribution and canopy structure parameters of s. godejevii in different sandy land habitats ( semi - fixed sand dunes, fixed sand dunes and inter - dunes low land ), as well as species composition and their frequency in the herb layer of the scrubs, were compared the results were as follows : the population hi the semi - fixed sand dunes had the most developed root systems, followed by he population in the fixed sand dunes, and that hi the inter - dunes low land was the last
為了更有效地利用這一重要植物資源，本文對分佈於渾善達克沙地三種不同沙地生境（半固定沙丘、固定沙丘、丘間低地）黃柳灌叢的根系分佈，冠層特徵進行了研究，同時測定了灌叢下草本層植物種類組成及頻度，結果表明：半固定沙丘上的黃柳根系最發達（根系分佈深，數量大） ，固定沙丘的黃柳明顯不及前者，而丘間低地的黃柳根系最不發達。 -
The order of water - holding capacities in different plantation layers was as follows : soil layer > forest canopy > vegetation and litter layer
林分不同層次的持水量大小排序為：土壤層林冠層林下植被和凋落物層。 -
Glauca followed gap - dependent regeneration. they could undergo a long period in shady environment, once a gap emerged, they would exploite the sunlight, and grow quickly into the canopy layer
林隙干擾未出現之前能較長時間忍耐林下郁蔽環境，一有干擾發生就抓住機會快速生長，逐漸實現更新。 -
Many researches have been conducted in terms of vertical variation of hydrological fluxes from canopy layer aboveground to root layer underground, and what were compared between forest and non - forest land, between different forest types, and even between different parts of the same crown
國內外對于森林植被對水文通量的空間分佈的影響，在垂直方向上分層次進行水文通量變化過程的研究；在水平方向上按照林地與非林地的對比，森林植被類型之間的對比，甚至同一樹冠的不同部位的對比等，進行了細致的研究。 -
And this is the first full application of two - layer model in remote sensing. from separated evaporation and transpiration through the model some important field parameters can be derived, such as canopy resistance, co2 flux and crop water use efficiency. a simplified two - layer model was also presented in case of that only radiative temperature is available
在組分溫度的幫助下，實現了土壤蒸發和植被蒸騰的準確分離，並且用植被蒸騰速率反算出冠層氣孔阻抗、二氧化碳通量、以及作物群體水分利用效率等農田關鍵參數，是遙感獲得此類參數的新思路。
