茶树密植免耕可以快速高产,这已为近十年来各茶区的广泛实践所肯定,但是种植多年之后(十年以上)是否还持续高产呢?有人断言密植免耕茶园中后期再高产是不可能的。其理由是:届时茶树的个体和群体矛盾日益突出,将导致全园植株衰弱;与此同时,因树冠的高度郁蔽,群体的光能利用率也会渐次降低,由此而不可避免地走向低产。根据我们的进一步研究,密植免耕茶园不仅可以速成高产,而且能够稳产高产并历经二十年以上仍不衰退。
Tea tree dense no-tillage can be quickly and yieldably, which has been affirmed by extensive practice in various tea areas in the past decade. However, after many years of planting (more than ten years), is there still a sustained high yield? Some people have asserted that the later high-yielding in close-planting and no-tillage tea gardens is not possible. The reason is that the contradiction between the individual and the group of tea trees will become increasingly prominent at that time, which will result in the weakening of the whole plant. At the same time, due to the high density of the canopy, the utilization rate of light energy of the group will also gradually decrease, Low yield. Based on our further research, the dense-planting no-tillage tea plantations can not only produce high-yielding fruits at a rapid rate, but also maintain stable and high-yielding crops and remain unchanged for more than two decades.
