子京(Madhuca hainannensis)是海南岛的五个特类珍贵用材树种之一。种子成熟于四月份,正逢海南的干旱季节。由于子京种子极易发芽,种粒也较大,其幼苗主根发达,生产上常采用直播造林。但出苗后受干热气候影响,一般保存率较低。如不及时播种,种子很快失去发芽力。为此,作者用正交表安排试验,以探索子京种子的贮藏方法,以期达到短期贮存的目的,使直播造林的时间延至雨季进行。
Madhuca hainannensis is one of five special species of precious timber species in Hainan Island. The seeds mature in April, coinciding with the dry season in Hainan. As the seed can easily germinate seeds, seeds are larger, the main seedling developed, the production often used live afforestation. However, after the emergence of dry and hot climates, the general preservation rate is low. If not sown in time, the seeds lose their germination quickly. Therefore, the author arranged the experiment with orthogonal table to explore the storage method of Zijing seeds, in order to achieve the purpose of short-term storage, so that the direct seeding afforestation time to the rainy season.
