In the planting of vegetables, cucumber, tomato, eggplant and other vegetables have a long growth cycle and need a large amount of fertilizer. After entering the flowering and fruiting period, vegetable farmers begin to apply fertilizer to promote flowers and fruits. However, in the frequent watering and fertilizer, many vegetable farmers are flushing a fertilizer for a fertilizer, their point of view is: "so much fertilizer, this does not work, that also works!"

The type of fertilizer should not be changed frequently. The amount of fertilizer required during the growth period of vegetables is particularly large. Fertilizer should be applied after the flowering and fruiting period. The function of fertilizer application is to promote flowers and fruits. However, in frequent watering and fertilizer washing, many farmers like to change one fertilizer at a time. They think that there are many types, even if one does not work, there is another.

Frequent replacement of fertilizer, it is possible to encounter good fertilizer, promote plant growth, but if once encountered fake and shoddy products, but no effect can also, if encountered some harmful crops products, it can suffer. For example, in order to quickly show the effect, some products add excessive plant growth regulators in fertilizers, such as sodium nitrophenolate. Such irrigation and fertilization can generally take effect in 2-3 days after application, but after 6-7 days, vegetables will appear yellow leaves, wilting and other symptoms, and the roots of vegetables will be destroyed after continuous irrigation for 2-3 times. In short, the replacement of irrigation and fertilization should not be too blind, and it is even more undesirable to change it once.

Do not understand the characteristics of fertilizer, frequent replacement, blind application, there is a great risk. At present, the agricultural materials market is full of a large number of fake and inferior fertilizers, a careless one can lead to poor vegetable growth, low yield and poor benefit, and a serious one can lead to no yield or harvest.

Although the demand characteristics of fertilizer for each kind of vegetable are different in different periods and different environments, for irrigation and fertilization, the emphasis is on flowering and fruiting period, and the proportion of fertilizer required is basically stable. It is suggested that vegetable farmers can classify the commonly used irrigation and fertilization and select several suitable irrigation and fertilization formulas.

If a fertilizer with reasonable nutrient content, stable quality and good effect is found, it may be used continuously, which not only can better understand the effect of irrigation and fertilization, but also can reduce the risk of production and operation.
