杉木是我国一个主要用材树种,在我国南方栽培很广。一般来说,决定杉木造林成材有五个条件,即气候、土壤、良种壮苗、造林质量、抚育管理。这五个条件又是互相影响,互相制约的。其中气候、土壤是前提,良种壮苗是基础,造林质量是关键,抚育管理是保证。在这里,我们仅就五星岭林场十七年的生产实践,专门谈谈杉木的幼林抚育。幼林抚育是巩固造林成果,促进林木速生丰产最重要的一环,杉木造林更是如此,通过幼林抚育,解决幼树与杂草、幼树与土壤的矛盾,而幼树与气候的矛盾,则是随着上述矛盾解决而解决的。改变了土、水、肥、气、光、空间等环境条件,幼树就生长快,长得好。但抚育方式不当,或抚育不及时,又会走向反面,如使幼树变成“小老头”,受压,畸形,萌条丛生等等。所以我们很有必要研究杉木幼林抚育的规律,寻找花钱少,成林快的抚育技术。 Cunninghamia lanceolata is one of the main timber species in our country and is widely cultivated in southern China. In general, there are five conditions for determining the afforestation status of Cunninghamia lanceolata: climate, soil, strong seedlings, afforestation quality, tending and management. These five conditions are mutually influential and mutually restrictive. Which climate, soil is the premise, seedling is the foundation seed, afforestation quality is the key, tending management is guaranteed. Here, we only seventeen years of production practice Wuxing Ling Forest Farm, specifically to talk about young fir forest tending. Nursery tending is the most important part of consolidating afforestation achievements and promoting fast-growing and yielding forests. This is even more so when afforestation is carried out in the fir forests. By nurturing young trees, the contradictions between saplings and weeds, young trees and soil are solved, Is solved with the above contradiction. Change the soil, water, fertilizer, gas, light, space and other environmental conditions, saplings grow fast, grow well. However, improper ways of tending, or tending is not timely, will go to the opposite, such as young trees become “little old man”, pressure, deformity, sprouting and so on. Therefore, it is necessary for us to study the law of young fir forest nurture and find out how to spend less and make the forest faster.
