1.喷水器的多目的利用在茶园中喷水器本来是用于灌溉的,我们在用于灌水的同时,还用于施肥、防治病虫、防止霜害、防止潮风害等作了研究。(1)灌水:茶园水的消耗量夏季最盛期为3～4mm/日,而冬季不到1mm/日。一般是在10～20cm 土层的 PF 值达2.3时,灌水20～30mm 的效果较好。灌溉效果因气象条件而异,某些年份可以增产5～10%。在一年中,一轮茶灌溉效果差,二、三轮茶效果好。(2)施肥:利用含氮率为15%的液体肥料作叶而施肥,其浓度在新梢生长期稀释到200倍,无新梢时稀释到100倍较好,使 1. Sprinkler multi-purpose use Sprinkler in the tea garden was originally used for irrigation, we used for irrigation at the same time, but also for fertilizers, pest control, prevent frost damage, prevent damp wind and other research. (1) Irrigation: The consumption of tea plantation water is 3 ~ 4mm / day in summer and less than 1mm / day in winter. Generally in the 10 ~ 20cm soil layer PF value of 2.3, irrigation 20 ~ 30mm better. Irrigation effects vary by meteorological conditions and may increase yields by 5-10% in some years. In a year, a round of tea irrigation effect is poor, two or three rounds of tea effect is good. (2) fertilization: the use of nitrogen fertilizer rate of 15% of the liquid fertilizer leaves and fertilization, the concentration of the shoot growth in the diluted to 200 times, no shoot diluted to 100 times better, so that
