玉林地区牛角瓜引种栽培试验初探

Primary study on calotropis gigantea trial of introduction and cultivation in Yulin prefecture

【目的】本文以玉林地区林科所、大义林场和陆川林场3个点不同密度牛角瓜种植为研究对象,找到适合玉林地区生长的密度,为该地区的栽培提供科学依据。【方法】采用完全随机设计,每个处理10株,3次重复,分析树高、地径、冠幅生长指标以及统计开花、结果和寒害,确定牛角瓜在玉林地区前期生长的最佳种植密度。【结果】1.5m×1.5m的种植密度在各项生长指标中表现较好,但该种植密度对牛角瓜后期树高生长、开花和结果量无显著影响。【结论】1.5m×1.5m的处理表现较好,可以作为栽培前期的最适合密度。

【Objective】This article takes different density calotropis gigantea in three points of Forestry Re-search Institute in Yulin prefecture,the Dayi Forest Farm and Luchuan Forest farm as the research object,find out the density of calotropis gigantea planting which suitable for Yulin prefecture condition,provide a scientific basis for the cultivation of the region. 【Method】Apply completely random design,each process-ing comply with the follows rules：10 strains,3repetitions,analysis of tree height,ground diameter,crown growth index and statistics of flowering,fruit,and cold injury,determine the the best planting density of calotropis gigantea grow in the early stage of the Yulin prefecture. 【Results】The results show that： during the growth,the index of planting density 1. 5 m×1. 5 m shows better,but no obvious effect on tree height growth,flowering and quantity of bear fruit in the the late stage of calotropis gigantea. 【Conclusion】 The growth performance of density 1. 5 m×1. 5m is better,which can be applied as the most suitable density for early cultivation.
