馬尾松，又名山松，松科松屬，在嶺南地區廣泛分布，資源充沛。近年來，隨著松柏類盆景的盛行，馬尾松盆景已成為嶺南盆景的熱門樹種之一。裁剪，是嶺南盆景造型手法中重要的手段之一，對松樹裁剪不當不但影響到松樹的整體布局，而且對松樹的生理機能亦產生重大影響。本人喜松，現將學到知識及實踐中出現的一些問題列舉出來，以供同行互相探討。 　　一、封口問題 　　在書刊和網頁上，有人提議用白乳膠封切口，但經本人試驗其效果近乎為零。持此觀點的人是將用白乳膠封雜木切口的方法套用到松樹上。殊不知松樹不同雜木，膠狀的松脂會一連幾天源源不斷流出，原先涂在切口上的白乳膠會隨松脂的外溢而流得一干二凈，所以用白乳膠封松樹切口絲毫不起作用。 　　用紅霉素藥膏封口，實際上行不通。紅霉素藥膏是一種軟膏，當膠狀的松脂從切口處流出時，軟綿綿的藥膏根本無力阻止松脂的外溢，說能預防傷口的感染，其實大部分的膏藥都隨著松脂外溢而流失，附在傷口上的是極少數，所起的作用不大。 　　用泥土封口。經本人試驗，效果倒是不錯。本人在山上裁切山松的枝條時，用山上素土在傷口處涂抹幾下，第二天觀察，傷口處不再流松脂。原來膠狀的松脂和固態泥土互相粘連而凝固在一起，有效地阻止了松脂的外流。 　
Pinus massoniana, and mountains, pine pinus, widely distributed in lingnan area, abundant resources. In recent years, with the prevalence of conifers miniascape, masson pine bonsai has become one of the top tree species in lingnan bonsai. Cutting, is one of important means in lingnan bonsai modeling technique, the improper pine cutting not only affect the overall layout of the pine tree, and physiological function also have a significant impact on the pine tree. I like pine, hereby will learn knowledge and some problems in the practice list, with each other for the colleague. A, sealing problems On the books and the web, someone proposed to use white latex incision, but after I test the effect is almost zero. Take that view of the people is to use white latex sealing the miscellaneous wood incision method applied to the pine. Little imagine different miscellaneous wood, pine gelatinous resin to flow out continuously for several days, the original white latex coating on the cut will all along with the spillover of resin flow, with white latex sealing pine incision so no doesn't work. Sealed with erythromycin ointment, actually it won't work. Is a kind of ointment, erythromycin ointment when gum rosin outflow from the incision, soft ointment, unable to stop the turpentine spillover, said to prevent wound infection, but most of the plaster with rosin spillover and erosion, attached to the wound is very few, the role of is not big. Sealed with mud. In my test, the effect is good. Himself in the mountains cutting mountain pine branches, in the mountains, the soil in place daub a few times, the observation of the next day, wound resin is no longer flow. The original colloidal resin and solid soil adhesion and solidify together, each other effectively stop the outflow of rosin.
