据1985年统计,宣汉县有茶园面积4.5万亩,其中投产面积约占57％,但茶树生长迟缓,投产迟,单产低,效益不高,1984年亩平只有50多斤,亩平产值46.5元。对此,我县结合低产茶园改造及茶树病虫综合防治,为提高茶叶产量及其经济效益,在加强茶园肥培管理的同时,在茶树上,喷布一种人工合成的新型植物生长调节剂P_(51),经过一年的小区限制试验和大面积示范,与对照比较增产均在15％以上。现将情况简要报道如下。
According to the statistics of 1985, Xuanhan County has a tea garden area of 45,000 mu and an area of about 57% of which is put into operation. However, the growth of tea trees is sluggish, production is delayed, yields are low and the returns are not high. 46.5 yuan. In this regard, my county combined with low-yield tea plantation and tea comprehensive control of pests and diseases, in order to improve tea production and economic benefits, while strengthening the management of fertilizer in the tea garden at the same time, in the tea tree, spray a new synthetic plant growth regulator P_ (51). After one year’s plot test and large area demonstration, the yield increase was above 15% compared with the control. The situation is now briefly reported below.
