开花期

And lower the pod shell soluble sugar content at the beginning of seed filling stage. The effect of nitrogen was different at different growth stages.3、Effect of nitrogen levels on soybean nitrogen metabolismNitrogen can increase nitrate reductase activity, and the effect was the most obvious in the peak period.

施氮可以提高开花期叶片淀粉含量，降低茎秆中可溶性糖含量，在成熟期降低叶片可溶糖含量，并在鼓粒始期降低荚皮可溶性糖含量。3、氮素水平对大豆氮代谢酶影响施氮可以提高硝酸还原酶的活性，且在酶活性峰值期作用效果最明显。

The results showed that the best formula of agronomic measure for yield of essential oil from spearmint ≥82.5 kg/hm2 and good quality was sowing time form 7th November to 22nd November, density 251000~362000 plant/hm2,fertilizer application of pure N 169.2~214.5 kg/hm2、P2O5 91.8~134.0 kg/hm2,and the optimum time for harvesting was when the buds reached about 10% of the main stem.

结果表明苏格兰型留兰香精油产量≥82.5kg/hm2且品质优的农艺措施的优化方案为：播期11月7日—11月22日，密度25.1~36.2万苗/hm2，施肥量纯N 169.2~214.5 kg/hm2、P2O5 91.8~134.0 kg/hm2，最佳收获期为主茎10%左右的花蕾开花期。

The treatments of NPK and NPK+BCF were better than those of N, NP, NK on the plant height, stem, leaves area, chlorophyll, bearing fruit stick, extent of unfolding, the time of blooming and bearing fruit, and plant soma changes of harvest time. The ratio of basal manure to after manuring and the different ratio of after manuring showed mutual effects: The excessive nutrient had unfavorable influences on plant growth and development in former time.

NPK+BCF及NPK的配方在株高、茎粗、叶面积、叶绿素含量、结果枝、展开度、开花期和挂果期、收获期植株营养体变化等指标上都优于NP、NK及只施N肥的配方；不同基追肥比例及不同追肥比例表现出共同的效果：前期施入过多的养分不利于茄子植株的生长发育。

By short-day hastening rate results were analyzed that the blooming time and maturity time of Zhonghuang13 was weaker sensitivity to photoperiod than other two varieties, plant height, node no.

通过短日促进率分析，中黄13的开花期和成熟期与其他品种相比对光周期反应敏感性较弱。

Yield reduction by root cutting was higher in larger panicle variety than in smaller panicle variety, and higher at panicle initiation than at flowering stage.

切根对大穗型品种籽粒产量的影响大於对小穗型品种的影响；在穗分化期切根的影响大於开花期。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
