固体水对苗木作用效应的研究

固体水为干旱、半干旱地区的抗旱造林提供了一种新的途径 .为了有效地指导其在野外造林的应用 ,在温室可控条件下 ,从植物水分状况、土壤含水量变化及微生物数量等方面 ,研究了固体水对北方主要造林树种油松和侧柏苗木生长的影响 .结果表明 ,使用固体水可提高土壤含水量 ,明显改善苗木的水分状况 ,减轻水分胁迫 ,其中效果最佳的是接触面积为 5 0cm2 的纯固体水和 38cm2 的加剂固体水 .根据固体水释水速率和供试苗木的水分状况及生长表现 ,在没有其它水源补充的条件下 ,艾德迈尔固体水至少可以维持油松和侧柏苗木生长 2个月

The effect of solid water on seedlings

Solid water affords a new approach to drought resistant planting in arid and semi arid area. In order to guide effectively to its application in the outdoors afforestation, the impacts of solid water on the growth of main tree species such as Pinus tabulaeformis and Platycladus orientalis used in northern China reforestation were studied in the green house by water status of the seedlings, variation of soil water content and quantity of microorganism etc. The results show that it can increase soil water content, improve water status of seedlings evidently, alleviate water stress by using solid water, in the experiments the original solid water whose area contacting the soil is 50?cm 2 and the new solid water whose area is 38?cm 2 have the best effect. According to the rate of solid water releasing moisture, the water status and growth of the plants, the growth of seedlings can be maintained for more than two months by using solid water in the condition of without other water resources.
