密度 1.(密集的程度) density; thickness 火力密度 density of fire; 兵力密度 density of troops; 那個(gè)國(guó)家的人口密度為每平方英里685人。 the population density of that country is 685 per square mile.2.[物理學(xué)] (物體的質(zhì)量和其體積的比值) density 電流密度 current density; 海水密度 seawater density; 水銀的密度比水大得多。 mercury has a much greater density than water.; 密度計(jì) densimeter; densitometer; density gage; density indicator; gravitometer
These significant increment in yield compensate for the 3 to 5 more months the grower has to wait for harvest when using densities of 3 , 300 to 5 , 000 plants , in comparison with the normal density of 1 , 400 - 1 , 600 plants per hectare ( table 1 ) 與傳統(tǒng)的1400 ~ 1600株/公頃相比,使用3300 ~ 5000株/公頃的種植密度所獲得的產(chǎn)量增加完全可以補(bǔ)償種植者等待收獲的3 ~ 5個(gè)月時(shí)間(表1 ) 。
What myr has pointed out in china is that many of the present day recommendations are outdated because they were either obtained with low inputs ( low yielding varieties , low fertilizer use , low plant populations , etc . ) or imbalanced fertilization 中國(guó)的最高產(chǎn)量研究指出,許多現(xiàn)行的推薦已過(guò)時(shí),因其或在低投入(低產(chǎn)品種、低施肥量、低種植密度等)或在不平衡施肥的情況下獲得。
Studies on the effects on the growht , yield , quality with different planting densities of the watermelon variety zhonghuaquanwang results that the best planting density is 500 individual plants in 667 m ^ 2 area with 3 stems of the grafted individual 摘要研究不同種植密度對(duì)于中華拳王西瓜生長(zhǎng)、產(chǎn)量、品質(zhì)等影響,結(jié)果表明,中華拳王嫁接西瓜采用三蔓整枝,每667平方公尺種植此品種的最佳密度為500株。
Firstly we maked sure method of isolating arabidopsisis mutant by thermal imagings in many ways on trial , optimize conditions for isolation , and confirm the good period of seedlings and fine density for isolation , select correct isolating pressure ( drought and h2o2 ) that is fit for isolate mutant . secondly we obtain an ml population derived from 0 . 4 % ethyl methanesulfonate ( ems ) - mutagenized wild type arabidopsis thaliana 本實(shí)驗(yàn)首先是對(duì)利用遠(yuǎn)紅外成像技術(shù)篩選擬南芥突變體方法的可行性進(jìn)行多方面的試驗(yàn),優(yōu)化篩選條件、確定篩選所需幼苗的生長(zhǎng)時(shí)間、種植密度,界定用于篩選所需的脅迫(過(guò)氧化氫和干旱)選擇壓力。
The sub - model for design of population density was developed according to the principle of determining boll number from target yield , fruit node from boll number , fruit branch from fruit node and population density from fruit branch by integrating the effects of sowing date , cutout date , effective temperature accumulation above 12 , variety type , and fertilizer and water management levels . sowing rate was then decided by integrating the effects of different soil water and salt contents , ph , temperature and sowing style on seedling emergence rate with relative weight method 基于“以產(chǎn)定鈴、以鈴定節(jié)、以節(jié)定枝、以枝定苗”的原理,同時(shí)考慮播種日期、打頂日期、 12的有效積溫、品種株型特性、肥水管理水平差異等因素來(lái)確定適宜的種植密度;在此基礎(chǔ)上,應(yīng)用相對(duì)權(quán)重法計(jì)算土壤含水量、含鹽量以及整地質(zhì)量和播種方式等多個(gè)生態(tài)環(huán)境因子對(duì)出苗率的綜合影響,進(jìn)而確定播種量。
