A Series of Techniques for the Oil Tea Tree Clone Bearing Early and Plenty

This article shows a series of techniques for the breeding of Oil Tea tree grafted in a great number. The article also show four key points for the planting: making the grafting stronger; planting in the season with plenty of rainfall; protecting them from weeds, cattle and other's damage; planting with older grafting after breeding in the nursary for 1.5 or 2.5 years. The test indicated that in order to get rich yield, we must pay more attention to the following: planting several clones in a certain field to insure 4~5 clones flowering at the same time; growing grafting denser than the plantation with seedlings; putting high clone tree together with low one in order to get more energy from the sun; cutting the tip and selecting the side shoots to form suitable crown when they are very young; fertilizing with a suitable proportion of N, P, K; planting some kinds of plants between graftings during the first 6 years. 8 surper clones have been selected from 200 clones. The tests also show that the plantation grown with these clones could produce 210.0kg edible oil per hectare every year in general condition, and produce 375~600 kg oil in good condition. All of these techniques have been put into use in the main Oil Tea areas in our country, reaching a total area of over 330 hectares.
