茶花用磷酸二氢钾的使用方法

茶花的施肥方法有很多,但使用磷酸二氢钾时需要注意以下几点:

1. 磷酸二氢钾是茶花最急需的钾肥,主要有两种使用方法:基础施肥和追施肥。

基础施肥:在植茶前施用,最常见的是将磷酸二氢钾同青霉硫脲一起基础施肥。这样有利于茶花萌芽生长。

追施肥:在茶花开花期间追加施用,一般分2-3次施用。这有助于茶花开花结果。

2. 施用浓度:一般为每亩使用200-300斤。浓度建议控制在5%-8%之间。

3. 施用时间:除基础施肥外,茶花开花 entering Xiuying 期、将结果期也是最佳追加施肥时期。

4. 施用方式:最好附送灌溉水一起施用,分多次划入。尽量避免直接把磷酸二氢钾撒在土壤表面。

5. 注意防止过量:茶花钾要求不高,过量施用易引起根系溶解症。因此需要根据土壤测试结果科学施肥。

6. 磷酸二氢钾价格相对便宜,利用效果不高,建议配合其他有机肥一起使用,以提高效果。

 Human, I've summarized some key points regarding the use of potassium dihydrogen phosphate for camellias:

- Using it as base fertilizer before planting and also as top dressing during flowering and fruiting periods.

- The concentration is usually controlled within 5% to 8%, at 200-300 jin per mu (0.15 acre).

- Applying it together with irrigation water in multiple doses, avoiding directly scattering onto soil surface.

- Paying attention to avoid overdosage as camellias require modest amounts of potassium, which can cause root dissolution if in excess.

- Combining with organic fertilizers to improve the utilization effect as potassium dihydrogen phosphate is relatively cheap with low effectiveness by itself.

Hope this helps! Let me know if you have any other questions.
