春耕施肥的智者，哪位勇敢的农友能来解答这些疑惑？

1.在施用尿素后，不可立即浇水，因为它会转化为酰胺，如果立即浇水，就容易流失；同样，不能在大雨前施用。

2.果树中应避免使用硝酸铵，以免造成中毒。

3.长期施用硫酸铵会增加土壤酸性和破坏土壤结构；在碱性土壤中使用时，它们中的铵离子被吸收，而剩余的酸根可能与钙反应导致板结。

4.虽然微量元素对作物至关重要，但不应忽视其他营养素，否则可能影响作物生长发育。

5.混施碱性肥料与铵态氮肥会导致氨挥发损失降低肥效。

6.化肥与根瘤菌混合施用可能杀伤或活菌，从而使其失效。

7.尿素和碳铵不能同时使用，因为尿素需通过腺酶转变才能被作物利用，而碳铵加速了这个过程中的氮挥发损失。

8.碳铵与菌肥混合也不可行，因为它会对活性菌产生毒害作用，使其失去效果。

9.acidic fertilizers should not be mixed with alkaline fertilizers as they will neutralize each other and cause nitrogen loss.

10.unfermented manure should not be used as it can cause root burn or the production of harmful gases for young seedlings, especially for tomatoes.

11.high concentration fertilizer should not be applied at once as it may damage plant roots and affect growth.

12.phosphorus-based fertilizers are best applied in a way that allows them to reach the root zone, rather than being scattered on the surface where they may be absorbed by the soil.

These principles of spring planting fertilizer application need to be studied by farmer friends, and welcome everyone to supplement more knowledge points together to exchange ideas.
