There are many varieties of water-soluble fertilizer, different types of water-soluble fertilizer have different characteristics, and the use interval is also different.
1. Good water-soluble fertilizer
Good water-soluble fertilizer is the product of mature fertilizer technology, the characteristics are very obvious, it is not only good raw materials, but also has no impurities after dissolution, and the absorption and utilization rate is very high, generally 10-15 days on the line.
2. Relatively low-end water-soluble fertilizer
Compared with the low-end water-soluble fertilizer, it is generally the product of the transition from traditional fertilization to modern fertilization, because the technology is not very mature, there are more impurities after dissolution, and the utilization rate of absorption rate is not too high, so it should be applied frequently, generally once every 7-10 days.
3. Water-soluble fertilizer containing hormones
Some trace element water-soluble fertilizer, in order to have an obvious effect, will add a large number of plant growth regulators, this fertilizer can be used 1-2 days after the effect can be seen, although it can improve the yield to a certain extent, but it is not recommended to use often, so as not to break the growth law of plants, resulting in premature aging of crops, but crops in the case of particularly weak growth, can be adjusted with this kind of water-soluble fertilizer. Under the normal growth of crops, it can be used once a month.
