本发明涉及茶树种植技术领域，更具体地，涉及一种抑制茶树生殖生长的方法。The invention relates to the technical field of tea tree planting, in particular to a method for inhibiting the reproductive growth of tea trees.
背景技术Background technique
开花结实、生殖生长是茶树生理上的一个普遍现象，而花果必然影响第二年的茶叶产量和品质，并加速茶树的老化，因为茶树开花结籽一般会消耗茶树养分的 60%，减少来年的茶叶产量 20%以上，而茶叶的产业目的是多产茶叶，因此及时除去花果抑制茶树生殖生长，是茶叶增产的重要手段。影响茶树开花结实的因素主要有品种特性和外部因素，外部因素主要指气象因素、营养条件、外源激素及人为调控措施等。在选育优良品种的同时，人们可以通过激素代谢影响茶树的开花结实，即控制茶树的生殖生长。Blooming and fruiting, reproductive growth is a common physiological phenomenon of tea trees, and flowers and fruits will inevitably affect the yield and quality of tea in the second year, and accelerate the aging of tea trees, because tea trees usually consume 60% of the nutrients of tea trees when they bloom and set seeds, reducing the amount of nutrients in the next year. The production of tea leaves is more than 20%, and the purpose of the tea industry is to produce more tea leaves. Therefore, removing flowers and fruits in time to inhibit the reproductive growth of tea trees is an important means of increasing tea production. The factors affecting the flowering and fruiting of tea trees mainly include variety characteristics and external factors. External factors mainly refer to meteorological factors, nutritional conditions, exogenous hormones and artificial control measures. While breeding fine varieties, people can affect the flowering and fruiting of tea trees through hormone metabolism, that is, control the reproductive growth of tea trees.
小叶种紫芽茶(Camelia sinensis (L.) Kuntze var assamica)是广东省惠州市博罗县特有的一个茶树品种，于2010年被发现，经专家鉴定为一新的茶树品种。现该品种在广东省博罗县得到广泛推广种植，面积已达10000多亩。现成为当地茶叶的主产品种。但该品种栽培中表现出常年开花结果的特点，造成养分的大量消耗，新生枝条抽生数量较低，因而产量很低，远不能满足市场的需要。为了提高产量，抑制茶树的生殖生长过程，减少花果数量显得非常必要。目前小叶种紫芽茶产区主要采用人工除花除果的方法，不仅效率低，还易损坏茶树的新生枝芽。Camelia sinensis (L.) Kuntze var assamica is a tea tree variety unique to Boluo County, Huizhou City, Guangdong Province. It was discovered in 2010 and identified as a new tea tree variety by experts. Now this variety has been widely promoted and planted in Boluo County, Guangdong Province, with an area of more than 10,000 mu. Now it has become the main product variety of local tea. However, this variety shows the characteristics of flowering and fruiting all the year round, resulting in a large consumption of nutrients, and the number of new shoots is low, so the yield is very low, which is far from meeting the needs of the market. In order to increase the yield, inhibit the reproductive growth process of tea trees, and reduce the number of flowers and fruits is very necessary. At present, the production areas of small-leaf purple bud tea mainly adopt the method of manually removing flowers and fruits, which is not only inefficient, but also easily damages the new shoots and buds of tea trees.
