摘要:

本研究旨在为促进当年生大果沙枣(Elaeagnus mooraroftii)扦插育苗生长提供基础材料,为进一步开展大果沙枣扦插育苗相关研究奠定基础。以当年生大果沙枣扦插苗为试材,共设3个样区,12个处理,分别追施尿素、复合肥及对照,确定最佳施肥量。在3个样区中,样区二的大果沙枣株高最高、地径最粗、最长和最短枝条的长度最长、最长和最短枝条的基径最粗,分别为212 cm、16.26 mm、99 cm, 33 cm,6.28 mm,3.51 mm;样区二各个生长指标的隶属函数平均值为最大0.390,样区三的为最小0.189,综合评价为样区二>样区一>样区三,在样区二的土壤条件下,840 kg/hm2为最佳施肥量。本研究评价了促进大果沙枣扦插育苗生长的最佳施肥量,为大果沙枣扦插育苗栽培技术研究提供依据。

Abstract:

The purpose of this research is to provide basic materials for promoting the growth of current-year cutting seedlings of Elaeagnus mooraroftii, and lay a foundation for further research on the cutting seedling raising of E. mooraroftii. Using the current-year cutting seedlings of E. mooraroftii as the test materials, 3 sample areas and 12 treatments were set up, and urea, compound fertilizer and control were applied as topdressing, to determine the optimal fertilization amount. Among the 3 sample areas, the highest tree height, the biggest ground diameter, the highest length of the longest and shortest branch, and the biggest base diameter of the longest and shortest branch of E. mooraroftii were all observed in sample area 2, which was 212 cm, 16.26 mm, 99 cm, 33 cm, 6.28 mm, and 3.51 mm, respectively. The average membership function of each growth index in sample area 2 was the maximum of 0.390, while that in sample area 3 was the minimum of 0.189. The order of comprehensive evaluation of the three sample areas was: sample area 2 > sample area 1 > sample area 3. Under the soil condition of sample area 2, 840 kg/hm2 was the optimal fertilizer amount. This study evaluated the optimal fertilizer amount for promoting the growth of cutting seedlings of E. mooraroftii and provided a basis for the cultivation technology research on cutting seedlings of E. mooraroftii.
