Advantages of small seedlings

Xiao Shiying

Small seedlings are a method of planting tea seedlings that have been cultivated for 6 to 8 months. When the tea seedlings grow to more than 3 pieces of real leaves, the main stems are thick to reach 0.2 cm or more, and the plant is more than 15 cm, it can be planted. This is the "new technology" of tea tree cultivation created by tea farmers in Yunnan.

Small seedlings have many benefits than planting large seedlings for two years: the underground part of the small seedlings grows faster than some branches and leaves above the ground. After transplantation, new roots can be generated quickly, and they quickly return to growth. Small seedlings have less root damage, and are easy to transplant with soil, so it can achieve the effect of high transplantation rate and fast growth after survival.

The seedling of the seedlings is greatly shortened by the seedlings in the two years, and the seedlings can be educated properly, saving the seedlings of seedlings. Little seedlings are also more convenient than large seedlings and save freight. At the same time, the efficiency of small seedlings is also more efficient than large seedlings. Therefore, the cost of transplanting small seedlings is much lower than that of two -year seedlings.

We have done comparative tests of small seedlings and two -year large seedlings. Two years later, the shape of the small seedlings and the big seedlings is basically the same. I can't see who is the big seedlings and the seedlings. Large seedlings. This is the theoretical basis. This theoretical basis is the well -known botanical principle: during the entire life process of plants, when it is in a young age, it is most likely to accept the impact of environmental conditions. And strong ability to restore trauma. This principle has certain guiding significance for botanical and even the entire biological science, and the tea farmers in Yunnan have already applied it creatively to the tea village seedlings.

Of course, some advantages of the two -year large seedlings are not available in small seedlings. For example, the two -year -old seedlings have obvious complete plant morphological characteristics, which are materials selected by young trees. The tall and tall roots of the large seedlings are hard. It is not better to use it in the tea garden lack of planting. Moreover, the two years of large seedlings have strong resistance to root nodular insect disease and weeds. These advantages are that small seedlings cannot be replaced by transplanting.

In 1962, Puwen Farm used a small seedling transplantation method to establish a new tea garden, which was responsible for technical guidance. After years of hard work, more than 4,000 acres of more than 4,000 acres of tea gardens established in the 5,000 acres of tea gardens were carried out in a small seedling. Through the large -scale construction of garden construction, the entire process from cultivating tea seedlings to transplantation and tea management is the process of continuously summing up experience and lessons, and finally a set of practical technologies for promoting seedlings that can be promoted.

At that time, the small seedlings built on the Puwen Farm attracted a lot of people who visited and learned from the scriptures at that time, which became a model for promoting technologies such as seedlings. Today, decades have passed. With continuous efforts, small seedlings have long been the main method for building a new tea garden in Yunnan, and it has been promoted to widely adopted it. It plays a positive role in the construction of new tea gardens in Yunnan and even the country. Drinking tea sources, small seedlings transplanting technology have achieved such a happy results. First of all, they must be grateful to the predecessors of tea farmers in Yunnan. They have created the technology of small seedlings transplanting. At the same time, I also want to thank the later tea people, the continuous improvement and successful application promotion of small seedlings transplantation technology is inseparable from the practice and efforts of later people.
