fertility variation
解釋
育性變異-
On average, soil organic matter, total nitrogen, effective phosphorus content improved, but measures of the effective potassium in the soil, and the ph - value, worsened. from the perspective of spatial distribution, however, there is significant variation in soil fertility and quality
這樣,樣本的社會經濟數據也具有可比性;這樣我們就可以討論社會經濟及政策因素和土壤肥力變化之間可能的因果對應關系。 -
The variation curves of yield and grain protein content with soil water content ( or nitrogen ) were convex in high fertility ( or soil water content were 70 % and 80 % of field maximum moisture capacity ), and the soil water content ( or nitrogen levels ) before maximum protein content ( or maximum yield ) were the soil water content ( or nitrogen levels ) of coordinated variation of yield and grain protein content. [ conclusion ] coordinated variation of yield and grain protein content was possible in suitable condition
在高肥和土壤水分含量為田間最大持水量的70 %和80 %條件下,產量和蛋白質含量曲線均為凸型,蛋白質含量達到最大值之前對應的土壤水分含量為高肥條件下產量和蛋白質含量協同變化區間;產量達到最大值之前對應的施氮量為土壤水分含量為田間最大持水量的70 %和80 %條件下產量和蛋白質含量協同變化區間。 -
The variation of pi was little in the soils with three fertilities. and the proportion of pi in total p decreased while the proportion of po went up with the increase of soil fertility
不同肥力土壤無機磷量差異較小,隨土壤肥力提高,無機磷佔全磷比例下降,但有機磷量及其佔全磷的比例顯著增加。 -
Spatial - temporal variation of integrated soil fertility quality index in the peri - urban suzhou
蘇州城市邊緣帶土壤綜合肥力質量時空特徵 -
Using the regional trial data of guangdong hybrid rice in 1994 and 1995, and regional trial data of national late hybrid indica rice in 1995 and 1996, by t test, variation coefficient and regress coefficient, analysis and compare with the fertility character, steady character and adaptive character of teyou 524 and ck ( shanyou 63, shanyougui 33 ), the result showed : it was obviously that the fertility character and adaptive character of teyou 524 was better than ck, but steady character was between shanyou 63 and shanyougui 33, it was a quite good lat - mature and high - yield new hybrid rice combination
摘要利用1994和1995兩年廣東省雜交稻區域性試驗資料以及1995和1996兩年全國?型雜交晚稻區域性試驗資料,通過t檢驗、變異系數和回歸系數分別對特優524和對照種(汕優63 、汕優桂33 )的豐產性、穩定性和適應性進行分析和比較,結果表明:特優524的豐產性、適應性均明顯地優于對照種,而穩定性則次於汕優63 ,但好於汕優桂33 ,是一個較為理想的遲熟高產雜交稻新組合。
