湖北省红安县火连畈茶场有茶园1100亩,其中投产茶园800亩。81年茶叶产量205632.44斤,比1980年增产22.2%,比81年的计划产量超出28.5%,茶叶亩产257斤,比80年每亩提高57斤。这个茶场81年的茶叶生产在气候上是很不理想的,春茶前长期处于低温多雨,春茶减产(81年比80年减产11%),夏茶期问又遇干旱,在这些不利情况下茶叶仍获得增收(夏茶增26%,秋茶增68%),其主要因素是茶园加了新土,培厚了活土层,提高了茶园土壤保肥、保墒、保温的能力,因此实现全年茶叶增产。火连畈过去叫“可怜畈”,犁无三寸土,遍地是麻骨(麻骨石),土质瘠薄,人口稀少,一片荒凉。六十年代初期开辟的茶园尽管也搞了抽槽换土,但建园标准不高,土层浅薄,水土流失严重,有些茶树根系裸露。多年来依靠追施化肥增产,由于茶园土壤质地差,化肥流失严重,大大的降低了施用氮素化肥的经济效果。1980年全场茶园总共施用化肥52.7
Hung An County, Hubei Province fire tea plantation Cha Lian 1100 acres, of which 800 acres of tea plantation. The yield of tea in 81 years was 205,632.44 jin, an increase of 22.2% over 1980, exceeding the planned output of 81 years by 28.5%, 257 kg per mu for tea and 57 kg per mu for 80 years. The 81-year tea production in this tea plantation is not very good in climates. The long-term low temperatures and rainy spring before the Spring Tea, the declining production of the Spring Tea (81% less than the 80% in 1981), the drought in the summer tea season, Tea is still gaining more income (26% of summer tea and 68% of autumn tea). The main factor is the addition of new soil to the tea plantation, which increases the ability of preserving soil, preserving soil moisture and keeping warmth in the tea plantation so that To achieve full-year tea production. In the past, the fire was called “Poor 畈,” plowing no three-inch soil, everywhere is a numb bone (spine), soil infertility, sparsely populated, desolate. Although the tea gardens opened up in the early 1960s also took the place of replacing the soil with the trough, the standard of establishing the garden was not high, the soil layer was shallow, the water and soil loss was serious, and some tea roots were bare. Over the years rely on fertilizer topdressing, due to poor quality of the tea garden soil, serious loss of chemical fertilizers, greatly reducing the economic benefits of nitrogen fertilizer application. In 1980 the total use of chemical fertilizer 52.7 tea garden
