Technology for transplanting spring tea seedlings in tea area in north of Yangtze River

Abstract

The invention discloses a technology for transplanting spring tea seedlings in a tea area in the north of the Yangtze River, belonging to the technical field of tea culture. The technology comprises the following steps of: digging a transplanting ridge; shearing a seedling; field planting; irrigating for rooting; spanning a small plastic greenhouse; covering an agricultural film and a sunshading net; and removing the agricultural film and the sunshading net. The technology is characterized by comprising the following steps of: carrying out field planting on a tea seedling in a transplanting ridge, and then, ridging and hilling; spreading wet wheat bran, then covering the agricultural film and the sunshading net; and removing the agricultural film and the sunshading net in good time. Thus, the aims of heat insulation and water retention are achieved, seedling sunburn caused by high temperature is prevented, and the problem of tea seedling root rottenness caused by soil water accumulation in rainy summer is also solved. Compared with the prior art, the technology has the characteristics of no defoliation, rapidness in rooting and high survival rate after the tea seedling is transplanted; the survival rate of the annual tea seedling is 30% higher than that of the tea seedling transplanted by using the prior art; and the technology can be widely applied to the transplanting of spring tea seedlings in a tea area in the north of the Yangtze River, such as Shandong and Shanxi.

Description

technical field [0001] The invention belongs to the technical field of tea tree cultivation. Background technique [0002] The tea gardens bred by clonal tea seedlings, the fresh leaves of the tea trees are neat in shape and high in quality, which is the direction of tea development in the future. Clonal tea seedlings in Jiangbei tea areas such as Shandong and Shanxi are generally introduced from Jiangnan tea areas and then transplanted. [0003] Existing spring tea seedling transplanting technology in Jiangbei tea area has the following deficiencies in practical application: 1. After transplanting, some of the tea seedlings are in the relatively low-lying district furrow or ditch, and the soil near the root system in the summer rainy season Accumulated water will cause the roots of tea seedlings to rot; some are on ridges higher than the surface, which is not convenient for fertilizer and water management, and tea seedlings will die due to lack of water in the root system....

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved in the present invention is: overcome the deficiency of background technology, provide a kind of transplanting technology, solve when the tea seedling of Jiangbei tea area is transplanted in spring, temperature is low and air, soil are dry and cause tea seedling to fall leaf and die, and summer rainfall is heavy again. The problem of root rot of tea seedlings due to water accumulation in the soil
