What details do you need to pay attention to when choosing fertilizer for flowers?

It is important for flowers to choose fertilizer, but the details are more important for people who choose fertilizer at the same time. We all know that the production of flowers is inseparable from fertilizer, all producers will worry about a problem, that is, how to buy fertilizer, do not know how to choose fertilizer. So, today, let's take a look at several techniques for producing flowers and selective fertilizers.

First of all, the purchase of fertilizer can not only look at the price. Every producer hopes to choose a cost-effective fertilizer, but it is not reasonable to decide to buy it solely on the basis of price, which will affect the effectiveness of fertilizer in production. Yang Kuang-sheng, a professor and fertilizer expert at National Taiwan University and a technical consultant to Dahan Landscape Development Co., Ltd., points out that the purchase of fertilizer should not only look at it, but also ignore the relative value. Only when it can give full play to the effectiveness, so that producers can obtain high-quality products and ideal income, the economical fertilizer is worth choosing when calculating the cost comprehensively.

Take the average fertilizer with a nitrogen-phosphorus-potassium ratio of 20-20-20 as an example, the price offered by the supplier will be different for the same specification of fertilizer because of the difference in substance. Among them, there are three forms of nitrogen in fertilizer: ammonium nitrogen, nitrate nitrogen and urea nitrogen. For general flowers, the ratio of ammonium nitrogen to nitrate nitrogen can not exceed 3: 7; potassium may exist in the form of potassium nitrate or potassium sulfate. Potassium sulfate is cheaper than potassium nitrate, but the effect of potassium nitrate is better than that of potassium sulfate. Some fertilizers have the purity of potassium nitrate, while others are, but the 0.9% difference is much lower in price. Some iron elements in fertilizers exist in chelated state, while others are ferrous sulfate. the price of chelated iron is 60,000 yuan per ton and ferrous sulfate is no more than a few thousand yuan per ton. The difference in these raw materials directly leads to the difference in the price of the finished product. When choosing and purchasing, producers must carefully look at the instructions on the fertilizer packaging, seriously study the composition of the products, and finally choose according to their own needs and economic strength.

At present, the more popular way of fertilizer use is 75% controlled release fertilizer plus 25% water-soluble fertilizer, which is economical and effective to use according to this proportion. In the view of most people, the price of controlled-release fertilizer is high, which will increase the cost when used, but it is not. Water-soluble fertilizer will be wasted more in use, and the labor cost is higher. Controlled-release fertilizer is an encapsulated fertilizer, which can be released according to plant demand, which can reduce the waste of fertilizer, high efficiency, and can reduce labor, and the cost will be reduced in the end. In addition, when choosing controlled-release fertilizers, we should also pay attention to some instructions provided by suppliers, such as the composition differences between different brands, and some brands of fertilizers have patented technology that can promote the absorption of nutrients by plants. this information should provide a basis for selection.

Secondly, when selecting fertilizer suppliers, we should pay attention to their after-sales service. Some suppliers only sell products without after-sales service, while others will provide supporting services and they will provide a full range of fertilization plans according to the types of products produced by producers. The fertilizers used by plants are different at different growth stages. for example, fertilizers with high nitrogen, low phosphorus and low potassium should be used at the seedling stage, while fertilizers with low nitrogen, high phosphorus and medium potassium should be used when promoting flowering. For some producers, due to the short time in production, lack of experience, and lack of familiarity with the details of fertilizer use, the thoughtful service provided by fertilizer suppliers is even more important.
