肥料在农业生产中必不可少，它可以提高农作物生长速度，增产增质，对提高农业经济效益有很大的帮助。肥料虽好，但是也要使用方法正确，才能发挥它真正的作用，下面就给大家介绍肥料使用十大原则，以及肥料使用中的注意事项。

Fertilizer is indispensable in agricultural production. It can improve the growth rate of crops, increase production and quality, and is of great help to improve agricultural economic benefits. Although fertilizer is good, it must be used correctly in order to play its real role. Here are ten principles of fertilizer use and precautions in fertilizer use.

肥料使用十大原则 Ten principles of fertilizer use

1、使用尿素后不能马上浇水。Do not water immediately after using urea.

2、碳铵不能直接施在土壤表面。Ammonium bicarbonate cannot be applied directly to the soil surface.

3、碳铵不能在温室和大棚内施用。Ammonium bicarbonate cannot be used in greenhouses and greenhouses.

4、铵态氮化肥最好不要与碱性肥料混施。Ammonium nitrogen fertilizer should not be mixed with alkaline fertilizer.

5、硝态氮化肥最好不要在稻田施用。Nitrate nitrogen fertilizer should not be applied in paddy fields.

6、硫酸铵最好不要长期施用。Ammonium sulfate should not be used for a long time.

7、磷肥最好不要分散施用。Phosphate fertilizers are best not to be dispersed.

8、钾肥最好不要在作物后期施用。It is best not to apply potassium fertilizer in the later stage of the crop.

9、含氯化肥最好不要长期单独施用，需避免在忌氯作物施用。It is best not to apply chlorinated fertilizers alone for a long time, and it is necessary to avoid the application of chlorine-avoiding crops.

10、含氮复合肥最好不要大量用于豆科作物。It is best not to use nitrogen-containing compound fertilizers for legume crops in large quantities.

肥料使用注意事项 Precautions for fertilizer use

1、肥料要现配现用 Fertilizers should be prepared and used immediately

肥料一定要现配现用，特别是在水质不好的情况下，防止肥料成分与水中物质产生反应。

The fertilizer must be prepared and used immediately, especially in the case of poor water quality, to prevent the fertilizer components from reacting with the substances in the water.

2、挑选恰当的施肥时间 Choose the right time to fertilize

在晴天温度高的情况下，施肥应该选在早上十点之前，下午四点以后，避免在阳光强射下施肥;要避免雨天施肥，尤其是叶面喷施，避免肥料流失。

In the case of sunny days with high temperature, fertilization should be selected before ten o'clock in the morning and after four o'clock in the afternoon, avoid fertilizing under strong sunlight; avoid fertilizing in rainy days, especially foliar spraying, to avoid fertilizer loss.

3、滴灌施用水溶肥时，先滴清水 When water-soluble fertilizer is applied by drip irrigation, drip water first

滴灌施用水溶肥时，先滴清水。等管道充满水后开始施肥。施肥结束后立刻滴清水20~30分钟，将管道中残留的肥液全部排出。如不洗管，可能会在滴头处生长青苔、藻类等或微生物，堵塞滴头。

When applying water-soluble fertilizer through drip irrigation, water should be dripped first. Start fertilizing when the pipes are full of water. Immediately after fertilization, drip water for 20 to 30 minutes to discharge all the residual fertilizer in the pipeline. If the tube is not washed, moss, algae, etc. or microorganisms may grow on the dripper, blocking the dripper.

4、与农药混配时要注意酸碱度及是否产生凝絮 When mixing with pesticides, pay attention to the pH and whether flocculation occurs

在与农药混配举行灌根或叶面喷施时，要避免酸性肥与碱性农药混配、碱性肥与酸性农药混配，同时更要注意混合时是否有凝絮现象产生，如有凝絮产生，则禁止混合使用。

When mixing with pesticides for root irrigation or foliar spraying, it is necessary to avoid the mixing of acidic fertilizers and alkaline pesticides, and the mixing of alkaline fertilizers and acidic pesticides. At the same time, pay attention to whether there is flocculation during mixing. If flocculation occurs, mixing is prohibited.
