一、避免直接冲施 Avoid direct injection

由于水溶肥复合肥养分含量比较高，因此在使用的时候用量不能太多，在施肥前需进行二次稀释水溶肥，比较水溶肥冲施是出现烧苗伤根、苗小苗弱等现象，而且对水溶肥进行二次稀释，不仅利于肥料施用均匀，还可以提高肥料利用率。

Due to the relatively high nutrient content of water-soluble fertilizer and compound fertilizer, the amount of water-soluble fertilizer should not be too much when used. Before fertilization, it is necessary to dilute the water-soluble fertilizer twice. Compared with the flushing application of water-soluble fertilizer, the phenomenon of burning seedlings, damaged roots, and weak seedlings occurs. The secondary dilution of the water-soluble fertilizer is not only conducive to the uniform application of fertilizers, but also can improve the utilization rate of fertilizers.

二、少量多次施用 Small amount of multiple applications

由于水溶肥速效性强，因此在土壤中长期存留，因此可以采取少量多次的施肥方法，减少因为大量施肥而造成的淋溶损失，也是符合植物根系不间断吸收养分的特点，一般来说每亩地施用量在3～6千克。

Because water-soluble fertilizers are quick-acting, they remain in the soil for a long time. Therefore, a small amount of fertilization method can be adopted to reduce the leaching loss caused by large-scale fertilization. It is also in line with the characteristics of plant roots that continuously absorb nutrients. The amount of application per mu is 3 to 6 kg.

三、注意养分平衡 Pay attention to nutrient balance

水溶肥一般采取浇施、喷施，或者将其混入水中，采取滴灌或者喷灌的灌溉方法，需要注意的是，在使用滴灌施肥，由于作物的根系生长密集且繁多复杂，因此对土壤的养分供应依赖性减小，更多依赖于通过滴灌提供的养分，如果施水溶肥时配方比例不平衡，会影响作物生长，而且施用水溶肥的时候，禁止大水漫灌或流水灌溉等传统灌溉方法，这样会导致肥料浪费和施肥不均匀。

Water-soluble fertilizers are generally watered, sprayed, or mixed into water, and drip irrigation or sprinkler irrigation is used. It should be noted that when using drip irrigation fertilization, due to the dense and complex root growth of crops, the supply of nutrients to the soil The dependence is reduced, and it is more dependent on the nutrients provided by drip irrigation. If the formula ratio is unbalanced when applying water-soluble fertilizer, it will affect the growth of crops, and when applying water-soluble fertilizer, traditional irrigation methods such as flood irrigation or flowing water irrigation are prohibited. This results in wasted fertilizer and uneven fertilization.

四、配合施用 Cooperate with application

水溶肥料为速效肥料，大部分都是用于追肥，小编在这里提醒各位一点，就是在常规的农业生产中水溶肥是不能替代其他常规肥料的，应该要做到基肥与追肥相结合、有机肥与无机肥相结合、水溶肥与常规肥相结合，，既能降低施肥成本，又能发挥各种肥料的优势。

Water-soluble fertilizers are quick-acting fertilizers, and most of them are used for top dressing. The editor here reminds you that water-soluble fertilizers cannot replace other conventional fertilizers in conventional agricultural production. The combination of fertilizer and inorganic fertilizer, and the combination of water-soluble fertilizer and conventional fertilizer can not only reduce the cost of fertilization, but also give full play to the advantages of various fertilizers.

五、尽量单用或与非碱性农药混用 Try to use alone or in combination with non-alkaline pesticides

很多菜农在蔬菜出现缺素症或根系生长不良时，会通过采用喷施水溶肥的方法加以缓解，但需注意的是水溶肥要尽量单独施用或与非碱性的农药混用，以免金属离子起反应产生沉淀，防止出现叶片肥害或药害。

Many vegetable farmers will use the method of spraying water-soluble fertilizers to alleviate the deficiency of vegetables or poor root growth. However, it should be noted that water-soluble fertilizers should be used alone or mixed with non-alkaline pesticides to avoid metal ions. The reaction produces precipitation to prevent leaf fertilizer damage or phytotoxicity.

六、避免过量灌溉 Avoid over-watering

1、以施肥为主要目的灌溉时，达到根层深度湿润即可。

When irrigating with fertilization as the main purpose, the root layer can be deeply moistened.

2、对于不同的作物，根系生长深度自然有所不同，因此可以用铲随时挖开土壤了解根层的具体深度。

For different crops, the root growth depth is naturally different, so you can dig the soil at any time with a shovel to know the specific depth of the root layer.

3、过量灌溉不仅会增加灌溉成本，还会对作物根部生长造成影响，比如说浇水后会使的养分淋失到根层以下，从而影响作物吸收，浪费肥料，特别是水溶肥中的尿素、硝态氮肥(如硝酸钾、硝酸铵钙、硝基磷肥及含有硝态氮的水溶性肥)极易随水流失。

Excessive irrigation will not only increase the cost of irrigation, but also affect the growth of crop roots. For example, after watering, nutrients will be leached below the root layer, which will affect crop absorption and waste fertilizers, especially urea and nitrate in water-soluble fertilizers. Nitrogen fertilizers (such as potassium nitrate, calcium ammonium nitrate, nitrophosphate fertilizers and water-soluble fertilizers containing nitrate nitrogen) are easily lost with water.

七、防止地表盐分积累 Prevent surface salt accumulation

很多大棚种植或者温室种植都长期采用滴灌施肥，从而造成地表盐分累积，严重影响作物生长，因此可以采用膜下滴灌抑制盐分向表层迁移。

Many greenhouses or greenhouses use drip irrigation for fertilization for a long time, which causes the accumulation of surface salt and seriously affects the growth of crops. Therefore, drip irrigation under the film can be used to inhibit the migration of salt to the surface.
