  1. The research can offer some important references to the population ecology of endangerous plant, too. based on the dates of two different circumstances, two standard life tables of form. taais chinensis var. mcarei population are founded by mathematical technique according to premising with " space deducing time ", and the curves of survival rate, mortality rate and killing power were drew. the results showed both of the survival curves of population appeared to be a type of deevey - iii and the high mortality of seeding is one of the important reasons which caused taxus chinensis var. mairei to be endangered, which badly limited the enlargement of form. taxus chinensis var. mcarei population

    由於南方紅豆杉無解析木，因而以「空間推時間」 、 「橫向導縱向」方法，將林林依胸徑大小分級，以立木級結構代表年齡結構，採用分段勻滑技術，對兩個不同生境的南方紅豆杉種群編制特定時間生命表，繪制存活曲線，結果表明不同生境的南方紅豆杉種群的存活曲線均趨于deevey -型，兩地差異較小，幼苗死亡率極高，不同生境的幼苗死亡率均達到96以上。
  2. This study dealt with the identification and evaluation of 8 maize populations from tropical and subtropical regions under the ecological conditions in zhengzhou, henan. results showed that the significant delaying days to shed and days to silk, discoordinating for the development of male and female, higher plant and ear height, more leaf numbers, high barreness, worse performance of ear traits compared with the ck ( temperate population ) were found, which showed the tropical and subtropical populations could not be utilized directly under the ecological conditions in zhengzhou. by using selection and improvement the tropical and subtropical populations can be used to broaden the genetic base of temperate maize breeding, beause of the greater genetic variation and higher selection potential within each population. the different performances of the sensitivity to photoperiod were observed among different tropical and subtropical populations and different traits. the asi, time to silk, ear height, leaf numbers, grain yield per ear could be used as the good evaluation traits for identifying the sensitivity to photoperiod

    對8個熱帶、亞熱帶玉米群體在鄭州生態條件下的表現進行鑒定和評價，結果表明，熱帶、亞熱帶群體散粉、吐絲期顯著延遲，雌雄不協調，植株和穗位高、葉片數增多、空稈率高，結實性差，果穗性狀均明顯劣於溫帶對照，在鄭州生態條件下不能直接利用，但是群體內具有較大的遺傳變異和選擇潛力，可以用來拓寬現有玉米種質的遺傳基礎；不同熱帶、亞熱帶群體的光周期敏感性不同；不同性狀對光周期反應的敏感程度不同， asi 、吐絲期、穗位高、葉片數、穗粒重可作為鑒定光周期敏感性的較好指標
  3. This has clearly demonstrated that high plant population is superior to the low

    這清楚地表明高種植密度優于低種植密度。
  4. As is shown in table 1, the yields at high plant population averaged across varieties were statistically higher than that at the low plant population at any fertilizer rates, and it tended to be true for any varieties tested

    如表1所示，在任何施肥量條件下，所有品種高密度處理產量平均值在統計上高於低密度處理產量平均值，這對所有供試品種都是如此。
  5. With this consideration, the factorial field experiments following the principles of maximum yield research （ myr ） were conducted in 1991 rice crop seasons, aiming at identifying the roles of variety, fertilizer and plant population in achieving high yield of rice and the best combination of these factors

    基於這種考慮，按照最高產量研究的原則在1991年水稻種植季進行了析因大田試驗，目的是確認品種、肥料和植株密度在獲得水稻高產中的作用和這些因子的最優組合。
  6. Results from corn research trials in yunnan pointed out clearly the importance of the interaction between crop variety and plant population when using fertilizer efficiently to obtain high and economical yields

    雲南玉米試驗結果清楚地指出，當施用有效量肥以獲得高經濟產量時，作物品種和種植密度間的交互作用很重要。
