  culture system

This study established a culture system of artificial Shiro formation and also provided a premise for formulation of culture substratum for fruit body formation of T.

In this culture system, the hormone did not affect the rate of oocytes that reached the final stages of meiosis but inhibited their transition from telophase I to metaphase II.

In vitro fertilization of bovine oocytes in protein-free culture system

We studied the possibility of fertilization of bovine oocyte-cumulus complexes, matured in vitro in a protein-free medium, in a protein-free culture system without preliminary capacitation of spermatozoa.

Thus, the efficient tissue culture system and transformation of haploid poplar plants were achieved.

The concept of the culture system for Chinese fir, based on the results of research in farming system and culture history of Chinese fir, was presented in this paper for the first time. Besides, the function, the evolution history, the classification and designing of the culture system have also been studied. And in the end,the development tendency of culture system of Chinese fir is pointed out.

ith the area of Chinese fir plantation increasing constantly, the soil fertility degradation of the site of Chinese fir plantation is increasingly serious. Controlled burning is one of the major causes which cause the soil fertility degradation of the site of Chinese fir plantation. On the basis of the achievements of previous related studies, we, in this paper, fully expound the effects of controlled burning on the slashes, soil and water loss, soil fertility and Chinese fir growth at home and abroad, summarize the advantages and disadvantages of controlled burning,and raise some corresponding countermeasures. This is of great significance for changing the traditional culture system of Chinese fir and for the sustainable use of the resources of the mountainous area in South China.

隨著杉木人工林面積的不斷擴大，杉木人工林地力衰退問題日益嚴重，而煉山是導(dǎo)致杉木人工林地力衰退的主要原因之一。本文在國家“七五”攻關(guān)子課題《煉山對杉木幼林生態(tài)系統(tǒng)影響機理及計量評價研究》連續(xù)１０ａ定位研究成果的基礎(chǔ)上，對國內(nèi)外有關(guān)煉山對采伐剩余物、水土流失、土壤肥力、杉木生長影響等問題進行全面闡述，同時對煉山利弊問題進行歸納與總結(jié)，并提出相應(yīng)對策，這對變革傳統(tǒng)杉木經(jīng)營制度、可持續(xù)利用南方山地資源具有重大指導(dǎo)意義。
