| 摘 要： | 研究了苍山大蒜管叶发生的叶位及其对蒜薹和蒜头产量的影响,以及管叶发生株率与种瓣大小、蒜种贮藏温度、湿度和光暗条件、播期及生长期土壤水分的关系。结果表明,管叶主要发生在植株内层第3,4叶位上;管叶株上一般只产生1片管状叶,其蒜薹短、蒜头小,产量分别比正常株的降低29.7％和30.3％,蒜种播前经低温贮藏,或选用较大的种瓣,均使管叶株率显著增高;适期晚播,或维持较高水平的土壤相对含水量,可以减少管叶的发生;在管叶出现后,及时划开管叶,可以消除管叶引起的蒜薹和蒜头产量损失。

| Abstract: | The position of tube-leaf on garlic (cv.Ciang Shan) plant and the effects of tube-leaf phenomenon on the scape and bulb characters were studied. The relationships among tube-leaf plant rate and seed clove size, pre-planting storage conditions (temperatures, relative humidities and light and darkness) of seed cloves, planting dates and soil water conditions were also investigated. The results showed that there was usually one tube-leaf on a tueb -leaf plant, it appeared mostly at the 3rd or 4th leaf numbered from scapes. Scapes were short and bulbs were small on tube-leaf plants, the yields of which decreased by 29.7% and 30.3% respectively. The pre-planting cold storage of seed cloves or the selection of cloves with large size can increase 1 ' e-leaf plant rate,but the late planting in right time or the high relative water content in soil during the whole growing stage can reduce the occurence of tubeleaves. After the occurence of tube leaves, spliting them can also reduce the yield losses of scapes and bulbs caused by tube leaves. |
