1982年8月底至10月底,我参加了江西赣州地区林业科学研究所组织的马尾松高产脂优树调查,全区共选出了胸径25～40厘米,产脂力为15克/10厘米侧沟长,相对产脂力超过对照木平均值2.5倍以上者有57株,绝对产脂力为10—15克,相对产脂力为2—2.5倍者125株。我们还发现日产量高达500克以上的马尾松,可见我国江南有些高产脂力的马尾松并不亚于湿地松,在某些方面,它比湿地松更优越。因为湿地松的种植要求土层肥厚,挖穴1米见方,还要施肥、抚育……。而我们现在所选的马尾松一般都是飞籽成林,系自然生长,即是人工种植的也不过是挖一锄头插棵苗,而且一般都是种在水土流
From the end of August 1982 to the end of October 1982, I participated in the survey of high-yield Pinus massoniana plantation organized by Forestry Research Institute of Ganzhou in Jiangxi Province. A total of 25-40 cm DBH was selected and the fat production was 15 g / 10 cm Trench length, the relative fat-producing more than 2.5 times the average control wood were 57, the absolute fat-producing capacity of 10-15 grams, the relative fat-producing capacity of 2-2.5 times the 125. We also found that the Pinus massoniana output of more than 500 grams per day shows that some high-yielding Pinus massoniana in southern China is as good as Pinus elliottii. In some ways, it is superior to Pinus thunbergii. Because the planted Pinus elliottii soil hypertrophy, dug 1 meter square, but also fertilization, tending ... .... The masson pine we now choose is generally a fly plantation, the Department of natural growth, that is, artificial cultivation is nothing but dig a hoe to insert seedlings, and are generally planted in soil and water flow
