T/ZLX 003-2020 Green food production technology specifications for Jiande Baocha

Scope

Main Technical Content: 4. New Development of Production Environment for Tea Gardens Tea gardens should be located on slopes below 25° with excellent ecological environments, an effective soil layer depth of at least 80cm, no hardened layers or clay-coated layers within 50cm, a pH value between 4.5 and 6.5, and an organic matter content of more than 1.5%. The groundwater level should be below 100cm, with predominantly loamy soils such as red soil, yellow soil, and brown-yellow soil. The production environment conditions should meet the requirements specified in NY/T 391. 5. Cultivation and Planting 5.1 Tea Garden Preparation When preparing tea gardens, attention should be paid to soil and water conservation. Based on the scale, topography, and other conditions of the base, a reasonable road system should be established and a complete irrigation system should be built to ensure water storage and drainage. Flatlands and gentle slopes below 15° should be terraced at the same level, while slopes between 15° and 25° should be equipped with terraced rows of tea plants. The cultivation of barren slopes should be divided into two stages: initial cultivation and re-cultivation. Initial cultivation should be carried out in summer or winter, with a depth of ≥50cm and removal of tree roots, grass roots, and stones. Re-cultivation should be conducted one month before planting, with the digging of planting trenches ≥30cm deep and 60cm wide. Enough base fertilizer should be applied to each 667m2 plot (250kg–500kg of cake fertilizer, 1000kg–2000kg of organic fertilizer, and 100kg–200kg of phosphorus fertilizer), followed by covering the soil to level it. 5.2 Varieties and Seedlings Main varieties include Wuniuzao, Longjing 43, Jiuke group varieties, Zhongbaizi No.1, Bailiezi No.1, and Zhonghuangzi No.1, which are suitable for making Biancha tea in Kendin County. Seedling cuttings should come from the mother gardens of the relevant varieties and meet the quality requir
