五、讲究施肥方法,提高施肥效益 在茶叶生产中,讲究施肥方法,使有限的肥料充分发挥其经济效益,无论是生产大宗茶还是名优茶都是十分重要的。由于名优茶价格高,更应讲究施肥方法,发挥名茶效应,提高施肥的经济效益。俗话说“没有不良的土壤,只有不良的耕作方法;没有不良的肥料,只有不良的施肥方法”,这充分说明了耕作和施肥方法对改良土壤和提高肥效的重要意义。一般来说,即使有很好的肥料,如果不讲究施肥方法,不注意施肥质量,也会使好肥料失去其优越性,达不到施肥效果,相反,即使肥料性质不算好,但只要讲究施肥方法,注意施肥质量,也可克服其缺点,发挥其效果。所谓讲究施肥方法,就是要采取“看天、看土、看树、看肥”施肥。看天,就是根据天气变化情况而施肥。早春名优茶生产期间,天气多变,如追施尿素后第二天下一场大雨,因尿素来不及分解成铵就会被雨水淋失。如施碳铵,施肥后立即下大雨却能防止氨的挥发,而土壤对碳铵有较强的吸附能力,不易被雨水淋失,效果反而比尿素好。所以,追肥时根据天气情况选用不同
Fifth, pay attention to fertilization methods, improve fertilizer efficiency In tea production, pay attention to fertilization methods, so that limited fertilizer to give full play to its economic benefits, whether it is the production of bulk tea or famous tea are very important. Due to the high price of famous tea, but should pay attention to fertilization methods, play famous tea effect, improve the economic benefits of fertilization. As the saying goes, “there is no bad soil, only poor farming methods; no bad fertilizers and only poor fertilization methods”, which fully demonstrates the importance of cultivation and fertilization methods in soil improvement and fertilizer efficiency improvement. In general, even if there is a good fertilizer, if you do not pay attention to fertilization methods, do not pay attention to the quality of fertilizers, but also make good fertilizer lose its superiority, fail to fertilization effect, on the contrary, even if the nature of the fertilizer is not good, Fertilization methods, pay attention to the quality of fertilizers, but also overcome its shortcomings, to play its effect. The so-called stress fertilization method, is to take “to see the sky, see the soil, see the tree, see the fertilizer” fertilization. To see the sky, it is based on changes in the weather and fertilization. During the production of famous tea in early spring, the weather is changing. For instance, the next day after the topdressing of urea, heavy rain will be lost due to the rain when urea is too late to decompose into ammonium. Such as the application of ammonium bicarbonate, immediately after the rain under heavy rain can prevent the ammonia volatilization, and the soil has a strong ammonium bicarbonate adsorption capacity, not easy to be leaching rain, the effect is better than urea. Therefore, top dressing according to weather conditions choose different
