中文摘要: |
在极端干旱气候环境以及质地较粗的含石土壤条件下,为了搞清楚成龄葡萄萌芽期合理的灌水量,采用深层坑渗灌技术,设了6个不同的灌水处理,通过边界效益分析法,分析了萌芽率与灌水量的关系。得到以下主要结论:萌芽期灌水量越大,枝蔓萌芽的均匀性越好,灌水量越小,枝蔓萌芽的均匀性越差;建立了萌芽期的水分性状函数和水分性状效率函数;当灌水量为62 844 m3/hm2时,萌芽率达到极大值78.25%,当灌水量为54 545m3/hm2时,水分性状效率达到极大值1.348×10-3%/m3。因此,葡萄萌芽期的合理灌水量范围确定在54 545m3/hm2与62 844 m3/hm2之间。 |

In the extremely arid climate and coarse texture soil containing stone, in order to find out the reasonable
irrigation water for mature grape-vine in germination period, under the condition of deep-pit irrigation with six different treatments,the relationship between germination rate and irrigation was analyzed with the method of boundary benefit analysis. The main findings are as follows: The more irigation water in germination period, the better uniformity of ger-mination and the less irrigation water in germination period, the worse uniformity of gemination. Both the function of wa-ter traits and the function of water traits efficiency was established. The maximum qermination rate was 78.25%0 with an irrigation water of 62 844 m3/ hm2,and the maximum water traits eficiency with an irigation water of 54 545 m3/hm2. The range of reasonable imigation quota for grape vine was from 54 545 m/hm2 to 62 844 m/hm2. |
