地膜栽茶技术 近年来,湖北宜都市在引种定植无性系良种茶苗建园实践中,摸索总结出了地膜栽茶技术,这一技术能显著提高茶苗移栽的成活率,避免移栽茶苗受冻害、干旱等灾害性气象的影响,确保建园成功。该技术适合在降雨量少、干旱年份多和冬季气温低于10℃的长江流域及江北茶区应用。具体技术要点如下。 1.测土选地 土壤条件为酸性土,pH值要求在4.5-6.0;背风向阳;土层深厚(1m以上),地下水位1m以下;有机质含量1.5％;水源充足,排灌方便。 2.抽槽改土 建园时必须抽槽改土,施足底肥。采用单条式密植的按行距130～150cm,宽窄行双条密植的按行距150～170cm放线抽通槽,槽宽60cm,深50cm。

In recent years, Yidu City, Hubei Province in the introduction of planting clones of good seedling tea plantation practice, groping summed up the filming tea technology, this technology can significantly improve the survival rate of transplanting tea seedlings to avoid transplanting tea Miao by frost damage, drought and other disastrous weather to ensure the success of the park. The technology is suitable for application in the Yangtze River and Jiangbei tea areas with less rainfall, more dry years and less than 10 ℃ in winter. Specific technical points are as follows. 1. soil testing and selection of soil conditions for the acidic soil, pH requirements in the 4.5-6.0; leeward sunny; deep soil (1m above), groundwater table below 1m; organic matter content of 1.5%; adequate water, irrigation and drainage convenience. 2. pumping tank to change the soil when the soil must be modified slot, Shi enough base fertilizer. The use of a single type of close-spaced row spacing 130 ~ 150cm, wide and narrow rows of two close-planting spacing of 150 ~ 170cm discharge line slot, groove width 60cm, depth 50cm.
