查询词典 ryegrass

Soil pot experiments were carried out to study the ecological effect of rare earth elements on rice in yellow brown earth. The ryegrass was used as an indicator plant to study the relationship between chemical available REs and REs absorbed by plant in four different soils and to study the concentrations threshold in soils.

本文通过生物盆栽试验研究了稀土元素对水稻的生长效应，并选用四种不同类型的土壤，以黑麦草为指示作物，研究稀土元素化学有效态和生物有效性之间的关系以及不同土壤上施用稀土的极限浓度等问题。

The study on the inherent relations of microbial biomass in red soil with soil nutrient cycling and ryegrass growth shows that the microbial biomass was not only significantly correlated with soil organic C, total N and available N, but also highly correlated with dry matter yield and N uptake of plants,indicating that soil microbial biomass could be used as an important indicator for soil fertility and plant production.

研究了红壤微生物量与土壤养分循环及植物生长的内在联系。结果表明，红壤微生物量不仅与土壤有机碳、全氮、有效氮等显著相关，而且与植物干物质产量及吸N 量也存在着良好的相关性，可作为指示红壤肥力水平和作物产量的重要指标。

On the other hand, mycorrhiza significantly decreased Cu and Cd concentrations in all plant species except for ryegrass.

两种植物混合种植情况下黑麦草显示了相对竞争优势，而菌根共生体能够提高三叶草的竞争能力。

RELATIONSHIPS BETWEEN FREE PROLINE CONCENTRATLON ,SOIL WATER CONTENT AND LEAF WATER CONTENT IN SIMULATED SWARDS OF PERENNIAL RYEGRASS LOLIUM PERENNE L .

模拟草地内黑麦草叶游离脯氨酸含量与叶含水量，土壤含水量之间的相互关系研究英文

模拟草地内黑麦草叶游离脯氨酸含量与叶含水量，土壤含水量之间的相互关系研究

Perennial ryegrass was grown in soil column systems in which soil water content was monitored by regular weighing the column and was maintained within a predetermined range by controlling watering frequency and water amount.Three types of water stress were imposed after the simulated swards were well established,cyclic,sustained and progressive,each of which was further divided into mild,moderate and severe levels,and an adequately-watered column was used as control.

实验植物黑麦草种植于自行设计和制作的圆形土壤柱内，土壤含水量采用称重法加以控制，通过调节灌水次数和每次灌入水量模拟3种类型的水分胁迫，即周期性胁迫、持续稳定性胁迫和渐进性胁迫，并以充足灌水作为对照。3种胁迫又分别设有3个水平，即轻度、中度和重度。

There is an intermediate type of ryegrass first produced by a New Zealand plant breeder.

还有一类中期黑麦草，为新西兰一名植物培养家首先培育出来。

Six soil free mixtures (Ⅰ. decayed grass fibre : slag : chicken dung = 3 : 1:1;Ⅱ. Decayed grass fibre: peat: slag2 : 2 :1;Ⅲ Decayed wood fibre: slag: chicken dung3 : 1: 1;Ⅳ. Decayed wood fibre: peat: slag2 : 2 : 1;Ⅴ. peat : slag chicken dung=2 : 1 : 1;Ⅵ. Peat : vermiculite : perlite = 2 : 2 : 1;Ⅶ. Soil.) were used as growth medium for perennial ryegrass turf establishing experiment.

以单一的基质为材料，调制成6种混合无土基质，分别为：Ⅰ3腐熟草质纤维十炉渣＋鸡粪；Ⅱ2腐熟草质纤维＋2泥炭十炉渣；Ⅲ3腐熟木质纤维＋炉渣＋鸡类；Ⅳ2腐熟木质纤维＋2泥炭＋炉渣；Ⅴ2泥炭十炉渣＋鸡类；Ⅵ2泥炭＋2蛭石＋珍珠岩、Ⅶ土壤。

Results showed that cultivation of forage crops, especially ryegrass and rye, in winter improved soil properties over cultivation of grain crops by lower soil pH and increasing contents of organic matter and available nutrients, which contributd to growth and possibly yield of the crop to follow.

结果表明：冬季种植牧草与种植粮食作物比较降低了土壤pH值、增加了土壤有机质和速效养分，特别是冬季种植多花黑麦草和黑麦明显增加了土壤有机质、碱解N、速效K和速效P含量，促进后作生长，为后季作物增产提供可能性。
