大叶相思是含羞草科相思属的常绿乔木。原产澳大利亚,生长迅速,耐干旱瘠薄,是南方水土流失严重的红壤和砖红壤造林的先锋树种。木材坚韧、纹理细致。用做家具、造纸和建筑等,均优于台湾相思。根系有根瘤能固氮,可改良土壤,促进林木生长。十多年来在我所引种成功的基础上,目前已为全省(区)内各地提供了部分种子推广试种,表现均为良好。现就育苗技术措施简介如下: 1.采种。大叶相思,每年8-9月为花期,翌年3月果熟。果壳呈黄褐色即可采种,种采回后经太阳晒至开裂去壳待育。2.选整圃地。苗圃地要选择阳光充足、土质疏松、肥沃、湿润,近水源且排水良好的沙质壤土。播种前先将圃地翻转曝晒,让其充分风化。作畦前撒适量六六六粉进行土壤杀虫。然后碎土起畦。畦高2.5厘米,宽1米。
Acacia macrophylla is an evergreen tree mimosa Acacia genus. Origin Australia, rapid growth, drought-resistant infertility, is a pioneer tree species of red soil and brick red soil afforestation in southern soil and water erosion. Tough wood, fine texture. Used as furniture, paper and construction, are superior to Acacia Taiwan. Root nodules can fix nitrogen, can improve soil, promote forest growth. For more than a decade, based on the successes I have introduced, we have provided some seed-breeding projects for various parts of the province (region) and have performed well. Seedling technology measures are as follows: 1. Seed collection. Acacia macrophylla each year from August to September for the flowering, ripe fruit in March the following year. Nutshell was brown to seed, the kind of mining by the sun to the cracked shelled shelled. 2. Select the whole garden. Nursery to choose sunny, loose soil, fertile, moist, near water and well-drained sandy loam. Before sowing, turn the nursery upside down so that it is fully weathered. Sprinkle the soil before planting amount of 666 powder insecticide. Then broken ground 畦.畦 2.5 cm high and 1 meter wide.
