施肥

Using the methods of field experiment,chemical analysis and biological statistics, effects of applying fertilizer on the law of absorption of Zn、Se and yield quality of spring wheat were systematically illuminated .

通过田间试验与室内分析及生物统计相结合的方法，研究了施肥对内蒙古土默川地区春小麦Zn、Se吸收规律及产量品质的影响。

The experiment studied soybean law of nitrogen absorption, distribution and transferring under different density and fertilizer treatment, taking BeiFeng-14 as test variety and adopting 5 factors and 3 levels treatment.

以北丰-14为供试品种，采用五因素三水平实施方案，系统研究了大豆在不同密度、施肥量处理下，对氮素吸收的规律。

In ttmtreatments of coring aerification, vertical mowing and raking, respectively, compared with the control treatment.

施肥与打孔、切根和梳草处理之间在草坪密度和地上生物量上存在显著的互作效应（P〈0.05）。

The process of lawn aerification is a straightforward one: it simply involves making a series of holes in your turf which allows water, air, and nutrients to reach the plants.

时间过的真快，一年一度的草坪aerification又开始了。我家这几年一直用同一家公司来做春季，秋季施肥，除杂草，还有aerification 和 lime。

The height of turfgrass and the length of the second leaf from the top were shown to significantly increase under the coring aerification, vertical mowing and raking, treatments compared with the control treatment, with the height of turfgrass increased by 34.64%,27.71% and 39.26%, respectively, and length of leaf increased by 24.03%,17.05% and 31.78%, respectively.

结果表明，打孔、切根和梳草3种措施对夏初修复的草坪草层高度和叶片长度有明显的促进作用（P〈0.05），草层高度依次比未修复＋未施肥处理增加34.64％、27.7l％和39.26％；叶片长度依次增加24.03％、17.05％和31.78％。

It is an item of newest scientific findings incorporating microbiolody , agrology , plant nutrition into an organic whole, mainly take many kinds of function type biological active funguses as the core , regard such organic matter as innoxious and treated beasts and birds excrement and urine , humic acid ,etc. as carriers, while cooperating with right amountly , micro- nutrition element, reach and improve the soil microorganism to trend towards the department, foster and apply fertilizer purpose of soil, fertilizer add nitrogen synergist and phosphorus , potassium chela mixture also, can apply fertilizer once only , does not need to topdress again in the whole breeding time.

是一项集微生物学、土壤学、植物营养学为一体的最新科研成果，主要是以多种功能型生物活性菌为主，以无害化处理后的畜禽粪便、腐殖酸等有机质为载体，配合适量中、微量营养元素，达到改良土壤微生物趋系，培肥土壤的目的，肥料中还添加氮肥增效剂和磷、钾螯合剂，可以做到一次性施肥，全生育期不需再追肥。

Often the agronomist did not use high or even balanced fertilization.

在中国，试验小区的密度一般为45000－55000株/公顷，这种密度是农学家几年前选育品种时所定的，但当时他们采用的施肥量不高，甚至不平衡，所以，最高产量也是对这种密度而言。

Proper feeding, care and fresh air make a healthy plant which is more resistant to inspect problems.

适当施肥，精心照料，外加充足的新鲜空气，能使植物健康茁壮，增强对病虫害的抵抗力。

The effect of nitrogen and potassium fertilizers on nutrient quality of two lettuees were different, increasing potassium or nitrogenous fertilizer was more effective in acid soil than in alkali one.

不同施肥处理对两种土壤上科兴3号和双尖莴笋营养品质的作用不一致。在酸性土壤上增施K肥或提高N肥的用量对莴笋营养品质的改善更有效果。

The effects of fertilization on rates of nitrogen ammonification,mineralization and nitrification were s tudied in the soil grown Amomum under tropical rainforest in Xishuanbanna using close -top Incubation.

采用封顶埋管法(Close-TopIncubation)研究了施肥后西双版纳热带雨林下种植砂仁土壤的氮素净氨化、净硝化和净矿化速率。

Objective: To study the effect of polycythemia on blood oxygen saturation.

裴蕾目的：观察RBC剧增而引起的高粘血症对血氧饱和度的影响。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
