The long beans have grown to 1.8 meters, but they don't grow pods anyway. the problem lies in the fertilizer.

Beans as a vegetable we often eat at home, the market price is also quite good, many areas choose to grow beans. But if beans grow to 1.8 meters without pods, it can only show one thing: excessive vegetative growth! It happens in vain. In other words, the use of nitrogen fertilizer is a little too large, while the use of phosphorus and potassium appears to be insufficient.

About vegetative growth and reproductive growth is very necessary for plant growth and development, for growing vegetables, different parts of the harvest, the choice of fertilization strategies will be different. For example, asparagus, this vegetable harvests stems and leaves on the ground, not the fruit of the cabbage after it blossoms. In this case, we are more eager for it to carry out more vegetative growth rather than reproductive growth, then fertilization should focus more like vegetative growth.

For crops that harvest fruit, such as cucumbers, watermelons, beans, tomatoes and other crops, when they are about to enter the flowering stage, that is, the stage of vegetative growth like reproductive growth, topdressing at this time needs to focus on reproductive growth.

The fertilizer requirement characteristics of crop reproductive growth and vegetative growth have been introduced in previous articles. In the vegetative growth stage, the growth rate of plants is very fast, and the cells synthesize rapidly, which is mainly manifested in the development of leaves and stalks. At this time, a large amount of nitrogen fertilizer is needed to ensure the completion of growth.

The reproductive growth stage is different, at this time mainly to the development of fruit, the body's sugar and other nutrients accumulation and storage need a lot of potassium to complete, and in addition, it is also the stage of large synthesis of nucleic acid and glycosides, a large amount of phosphorus is needed to ensure supply.

Therefore, the characteristics of fertilizer requirements are different in these two stages, and the fertilization strategies are naturally different. However, if there is too much nitrogen supply after entering the reproductive growth stage, the plants will grow too much, and the leaves will grow without flowering. This phenomenon is very common in family horticulture. For friends who have this phenomenon, potassium dihydrogen phosphate can be supplied in time to adjust the balance of plant fertilizer demand, and try not to add nitrogen fertilizer.
