自然草

林草模式的根际与非根际pH值都要比自然草模式的大，说明黑麦草较自然草能提高林地土壤的pH值。

Soil pH were higher on the rhizosphere soil and non-rhizosphere soil in forest-herb model than that in natural grass model . It showed that Lolium multiflorum can improve soil pH in contrast with natural grass .

林草模式根际与非根际之间、自然草模式根际与非根际之间有机质含量动态变化相关性都不显著。

Organic matter dynamics on the rhizosphere soil and non-rhizosphere soil in forest-herb model and natural grass model were not significant correlation .

两模式根际有机质差异不显著，非根际有机质在上半年和全年范围内差异显著，都是自然草模式大于林草。

The difference of organic matter on the rhizosphere soil was not significant between two models , but significant on the non-rhizosphere soil in the first half year and all-year .

不同地类的土壤蒸发量为桉树林坡面>自然草坡>阶间草坡。

The amount of the soil evaporation in Eucalyptus wood slope was the highest , followed by the nature grass slope , while it was the lowest in nature slope .

果园自然生草覆盖对土壤理化性状及大桃产量和品质的影响

Effect of natural grasses cover on soil properties and yield and quality of peach

自然生草在降温方面的效果不如覆盖稻草处理明显，但优于覆盖地膜和清耕（对照）。

Natural grass mulch was less effective than straw mulch , but more effective than plastic-film mulch and clean tillage in soil cooling .

果园自然生草、种植牧草后有增加空气相对温度、降低温度、减少温度变幅和防止水土流失的效果。

Wildly growing-grass and man-planting herbage can increase relative air humidity , decrease the temperature , lower the changes of temperature in a day and conserve water and soil .

具体研究结果如下：1相对于自然生草和清耕区，梨园间作芳香植物较显著提高了梨树旺盛生长季节（5月至9月份）的土壤微生物数量，改良了土壤微生物群落的结构。

Results were as follows : 1 Compared to natural grass and clean tillage plots , the soil microorganism quantity of intercropping aromatic plants plots in the period of pear vigorous growing season ( May to September ), and ameliorate the soil microbial community structure .

现在是更容易为自然提高，草喂牛肉，其中也有较高的奥米伽-3脂肪酸和类似的健康福利。

It is now much easier to order naturally raised , grass-fed beef , which also has higher omega-3 fatty acids and similar health benefits .
