Embodiment

[0013] A kind of northern tea tree antifreeze cultivation method, it comprises the following steps:

[0014] (1) Spread grass between rows. One is to loosen the soil shallowly in early June, spread 2000kg of wheat straw per mu of tea garden, press the soil on the grass, distribute it in a star shape, and spray water on the grass; the other is to spread grass in early November, shallow Plan and loosen the soil, spread 2000kg of wheat straw per mu of tea garden, press the soil on the grass, distribute it in a star shape, and spray water on the grass.

[0015] (2) Apply organic fertilizer and phosphate fertilizer. In mid-March or early September, dig a fertilization ditch with a depth of 50cm, apply soil and miscellaneous fertilizers at a ratio of 3750kg of dry tea and 15kg of pure phosphorus according to the yield of 50kg per mu, and apply them in layers together with the grass laid, and then the dug out Soil backfill.

[0016] (3) Top dressing. In mid-March, germination-ind...

Abstract

The invention discloses a freeze-proof culture method of tea plants in North China, which comprises the following steps: firstly, performing inter-row turfing, namely wheat straw turfing, between teaplant rows, covering the wheat straws with earth, and spraying water on the wheat straw, wherein the wheat straws are arranged in a star shape; secondly, applying organic fertilizer and phosphate fertilizer layer by layer together with the straws to be turfed and filling earth dug out back; and thirdly, applying topdressing at four times, wherein the nitrogen to phosphor to potassium ratio is 3:1:1. The culture method of the invention improves the ecological condition of a tea garden, keeps ground temperature, preserves soil moisture, saves water, preserves and fertilizers the soil, suppressesgrass, promotes roots, increases tea leaf yield, improves tea leaf quality, is simple in operation and easily acceptable to tea farmers and has a promising promotion prospect.

Description

technical field [0001] The invention relates to the field of tea tree cultivation, in particular to a frost-resistant cultivation method of tea trees, which is especially suitable for hilly tea areas north of the Yangtze River. Background technique [0002] Tea originated in China and is one of the three major beverages in the world. The distribution area of ​​tea is very wide, which can be roughly divided into four major tea areas: Southwest China, South China, Jiangnan and Jiangbei. Hubei and other places are tea regions in northern China, mainly producing green tea. The annual average temperature in this tea area is 15-16 degrees Celsius, and the absolute minimum temperature in winter is generally around minus 10 degrees Celsius. The annual precipitation is less, about 700-1000 mm, and the distribution is uneven. The soil of the tea garden is bare, and the tea trees in this area are often damaged by freezing. [0003] The main causes of freezing damage to tea trees are...
