一、要确保混合后叶面肥和农药的形状稳定 To ensure that the shape of foliar fertilizers and pesticides is stable after mixing

  这是因为叶面肥可能与农药发生化学或物理反应，影响农药的有效性或造成药害。 若药液有不良表现，则不适宜混合使用。混合后即使药液物理性状良好，也要先进行小范围的试验，看是否容易出现肥害药害，再大面积使用。

This is because foliar fertilizers may have chemical or physical reactions with pesticides, affecting the effectiveness of pesticides or causing phytotoxicity. If the liquid medicine has bad performance, it is not suitable for mixing. After mixing, even if the physical properties of the liquid medicine are good, a small-scale test should be carried out first to see if it is prone to fertilizer and phytotoxicity, and then used in a large area.

  二、叶面肥与农药的混用顺序要注意 Attention should be paid to the mixing order of foliar fertilizers and pesticides

  一般是用足量的水先配好一种单剂的药液，再用这种药液稀释另一种单剂；而不能先混合两种单剂，再用水稀释，以免发生不良反应，造成有效成分的破坏和物理性状的恶化。叶面肥混用时，叶面肥与农药混合的顺序通常为：叶面肥、可湿性粉剂、悬浮剂、水剂、乳油依次加入，每加入一种即充分搅拌混匀，再加入下一种。

Generally, a single dose of liquid is prepared with enough water, and then another single dose is diluted with this liquid; instead of mixing two single doses first, then diluting with water to avoid adverse reactions and cause effective Destruction of ingredients and deterioration of physical properties. When foliar fertilizers are mixed, the order of mixing foliar fertilizers and pesticides is usually: foliar fertilizer, wettable powder, suspending agent, water agent, and EC are added in sequence. 

  三、混合时要注意“水”的使用 Pay attention to the use of "water" when mixing

  水对药液的影响很大，水的酸碱度、离子浓度等，都会影响效果。配药用水以离子浓度低的中性水为好，如干净的雨水、河水等。

Water has a great influence on the liquid medicine. The pH and ion concentration of water will affect the effect. The water for dispensing is preferably neutral water with low ion concentration, such as clean rainwater, river water, etc.

  四、注意要现配现用 Be careful to use it now

  药液虽然在刚配时没有不良反应，但久置容易产生缓慢的反应，使药效丧失或易产生药害。如有的农药品种虽然在弱碱性条件下较稳定，但也要注意现配现用，若长时间放置也易失效。

Although the liquid medicine has no adverse reactions when it is just prepared, it is easy to produce slow reactions if it is stored for a long time, so that the efficacy of the medicine is lost or it is easy to cause phytotoxicity. Although some pesticide varieties are relatively stable under weak alkaline conditions, it is necessary to pay attention to the current preparation and use, and it is easy to fail if placed for a long time.
