查询词典 fertilization

Artificially induced a single 〓elevation could effectively drive the activation, in recently ovulated oocytes (12—13 h after hCG) however, a single Ca〓 increase was futile in initiation of activation and only repetitive 〓 rises were avalable, suggesting that the activation of recently ovulated oocytes requires oscillatory Ca〓 signals as occuring at fertilization.

This model considered many factors affecting the growth of maize, such as irrigation, rainfeed, CO_2 fertilization and predating the planting date by 5 days and 10 days when analyzing the change of yield and period duration. It further indicated how the production of maize was affected by the increase of CO_2 and PAR by using the data collected from the field experiment in Changping Experimental Station of China Agricultural Academy of Sciences.

模拟时分别考虑了灌溉、雨养、CO_2的肥效作用、播种期提前5天和10天条件下玉米的产量和生育期的变化情况，同时利用在中国农业科学院昌平试验站所做的田间试验结果进一步说明CO_2升高以及光强增加对玉米生产的影响情况。

In 1999, Kuwayama left the boine world to became head of research at Tokyo's Kato Ladies Clinic, which says it performed nearly 18,000 in-itro fertilization cycles last year. He soon deeloped a quick-freezing method using liquid nitrogen that reduced crystallization and lowered the need for alcohol.

在1999年，Kuwayama离开牛厂去成为东京Kato Ladies Clinic的研究主任，它说，他去年做了18000例体外受精实验，然后不久他发展了用液氮快速冷冻的方法，这种方法不仅降低了结晶而且也减少了对乙醇的需求。

The results showed that the best ratio of male parent to female parent was 1:3, and 210 kg/hm2 N fertilization was better. It indicated that hybrid seeds production in two crop seasons, especially the second crop season based on the utilization of ratoons of flue-cured tobacco which regenerated after hybrid seed was harvested in the first crop season, was beneficial to higher seed yield, lower cost, and less laborers employed as well.

结果表明，烟草杂交制种父母本比例以1：3较好；在中等肥力田块制种头季以施纯氮195~210kg/hm2较理想；利用头季杂交种收获后萌生的腋芽进行杂种二季制种在提高杂种种子产量，降低劳动量和生产成本等方面具有较理想的效果。

According to analyzing the relations between tar content and physical and chemical characters in flue-cured tobacco leaf,some measures of cultivation and flue-curing techniques on reducing tar content were summarized: cultivating and popularizing low tar content of tobacco varieties: increasing the potassium content of tobacco leaf by the adding the application to K fertilization; seizing the proper stage of topping and height and height and suckering in time;far improving the maturity of tobacco leaf; confirming a feasible process of flue-curing; developing and generalizing planting method anything else that could produce low tar content of tobacco leaf.

通过分析烤烟焦油产生量与烟叶的理化特性之间的密切关系，综述了降低烤烟焦油含量栽培调制技术措施：选育并推广焦油量低的烤烟新品种；增施钾肥，提高烟叶含钾量；把握打顶时期和高度，及时除芽；进一步提高烟叶成熟度；确定适宜的烘烤工艺；开发推广低焦油烟叶的其他栽培技术。
