为迅速改变丘陵荒山面貌,去年我地区引进湿地松种子300斤,我所播种130斤。由于土地条件的限制,圃地全部摆在坡度15—25度的酸性红壤山坡上,土质差、肥力低,又无自流灌溉条件,虽经春秋两季严重干旱,但平均高仍达20厘米,平均地径0.45厘米,产苗约40万株。在育苗的实践过程中,我们对湿地松苗期生物学特性进行了初步观察,对育苗的技术措施也有些体会,现作简要介绍。 In order to rapidly change the appearance of hills and barren hills, last year, my country introduced 300 kg of pine seeds, and I sowed 130 pounds. Due to the restriction of land conditions, all the nurseries were placed on the slopes of acidic red soil with a gradient of 15-25 degrees, with poor soil quality, low fertility and no gravity irrigation. Although the severe drought in spring and autumn resulted in an average height of 20 cm, The average diameter of 0.45 cm, about 400,000 seedlings. In the practice of nursery, we conducted a preliminary observation of the biological characteristics of the pine at the seedling stage, some of the technical measures of nursery experience, now a brief introduction.
