China is a big tea country. China's tea is very famous. Each region has its own famous tea. For example, like West Lake Longjing Tea, it is deeply loved by people. Then how to cultivate and manage Longjing tea? Let's take a look at it.
1. Select the tea tree variety suitable for Longjing tea
The well-known Longjing tea is native to Longjing tea area and is most suitable for frying Longjing tea. The “Longjing Changye and Longjing 43†series are selected from the Longjing tea group and belong to the second special early and early birth. Strong bud ability, resistant to mining, suitable for Longjing tea. The main varieties of the current West Lake Longjing tea are still Longjing, and the auxiliary varieties are “Longjing Changye and Longjing 43â€.
2, "three tillage and four cutting" combined with soil conditions
This is the intensive cultivation measures that farmers in Longjing tea area have summarized from long-term practice based on natural conditions and the characteristics of tea tree growth. Three-ploughing of soil, that is, through spring ploughing, ploughing, autumn ploughing, combined with fertilization, can not only mature the soil, deep worms, but also improve soil fertility, promote soil microbial decomposition of organic matter, and improve root growth and nutrient conditions.
Four-cut, refers to the cutting of spring grass, cutting grass, cutting autumn grass. It aims to solve the contradiction between weeds and tea trees, and to change weeds into fertilizers. Tea tree fertilization should be seen four times. One is to look at the fertilization of the day. Dry season is used during the rainy season and wet application is used during the dry season. The second is to see the land fertilization. The soil plate is tied to the animal fat, the soil is loose and the cake fertilizer; the thin layer of the top dressing is less, and the soil layer is thicker. The third is to see fertilizer and fertilization. Organic fertilizer and phosphorus, potassium fertilizer, base fertilizer in autumn and winter; nitrogen fertilizer for topdressing and root fertilizer. The fourth is to look at the tree to fertilize. The young tea trees are mainly phosphorus and potassium fertilizers, supplemented by nitrogen fertilizer; the tea leaves are mainly nitrogen fertilizer, and combined with phosphorus and potassium fertilizers.
3. Picking of Longjing tea
The system of timely, batch, multiple, and retaining leaves and the method of picking are the long-term experience accumulated in Longjing tea area. The quality of picking is directly related to the quality of the wine and the rise and fall of the growth of tea trees. The above picking technology effectively overcomes the contradiction between the growth and picking of tea trees and ensures the quality of fresh leaves of Longjing tea. The picking method can be divided into single hand picking and double hand picking.
The order of picking: varies depending on the growth status of the tea tree variety and the conditions of the producing area. The early harvesting plant first picks up the late harvesting garden; the mining with poor ground force first picks up the good ground power; the sunny slope first picks, after the dark slope Mining; low mountain first mining, high mountain mining; adult tea garden first, young or updated after the harvest. The general requirement is early tender mining, and the mining period should be sooner rather than later. When the bud leaves have a picking standard of 5% in the canopy of the tea garden, they should be mined. 40~44 batches were picked throughout the year. Spring tea, one batch every day or every other day; summer tea, take a batch every 3 to 5 days. Autumn tea, picking up every 5~8 days. Fresh leaves collected in each batch, tenderness, uniformity] clarity, freshness should be basically the same. Quality standard: one bud and one leaf initial exhibition, one bud and two leaves initial exhibition, one bud and two leaves, one bud and three leaves initial exhibition, one bud and three leaves. The bud leaves should be complete. Fresh leaf grading.
Grade shape length quality requirements
The first bud and one leaf are initially spread to one bud and one leaf, and the bud leaf angle is smaller than the leaf bud leaf length of 3 cm.
Grade 1 one bud and one leaf to one bud and two leaves initial exhibition, with one bud and one leaf as the main bud and the leaf length is substantially equal to the length of the bud leaf 3.5 cm.
Grade 2, one bud, one leaf, one bud, two leaves, the first bud, the main bud and the leaf length are substantially equal to the length of the bud leaf 3.5 cm.
Grade 3, one bud, two leaves to one bud, three leaves, and the initial leaf length is 4 cm longer than the bud leaf.
Grade 4, one bud, two leaves to one bud, three leaves are longer than the bud leaf length of 4 cm.
