用扦插方法繁殖的葡萄苗,其根系状况是影响插苗成活率和地上都生长的重要因素,也是判别苗木质量的重要指标。所以,在葡萄扦插育苗中,常常采用各种方法,提高生根率,促进根系生长。据试验,“踵状”插条扦插是一种有效的方法。“踵状”插穗即剪取一年生插条时将基部的一部分二年生部位也带上,构成一、二年生部位结合的形似是踵状的插穗。一般一年生部位留两个饱满芽,二年生部位相当于一年生部位的1/2至1/3长度即可。“踵状”插条打插有如下优点: 1.增加根量:试验表明,一年生单条插穗苗木平均每株根数为5.95条,而“踵状”插穗每株根数为12.85条。经方差分析,二者达到极显著水平。在“踵状”插穗中二年生处是主要的发根部位,尤其是一、二年生交界附近发根更多。二年生部位平 The grape seedlings propagated by cutting method, the root system status is an important factor that affects the survival rate of seedlings and the growth of the ground, and also an important index to judge the quality of seedlings. Therefore, grape seedling cutting, often using a variety of methods to improve the rate of rooting and promote root growth. According to the test, “heel” cuttings cutting is an effective method. “Heel-like” cuttings that cut the annual cuttings will be part of the base part of the biennial site also brought together to form a biennial shape is like a heel cuttings. General annual leave two full buds, biennials equivalent to the annual area of ​​1/2 to 1/3 length can be. “Heel” cuttings insert has the following advantages: 1. Increase the amount of roots: The experiment shows that the annual average number of single seedlings per plant is 5.95, while the number of “heel” cuttings is 12.85. By ANOVA, the two reached a very significant level. In the “heel” cuttings biennial Department is the main hair root sites, especially in the first and second year, more hair roots near the junction. Biennial position flat
