The principles of flower fertilization should be mastered and the cultivation techniques of edible fungi should be understood.

First, the newly planted plants are not applied. There are many wounds in the newly planted plants, and if they are stimulated by the outside world, they will not be able to heal and cause rotten roots.

Second, the flowering period is not applied. Fertilization during flowering will cause bud drop, flower drop and fruit drop.

Third, do not apply during the dormant period. Flowers stop or slow down their growth during the dormancy period, slow metabolism and poor photosynthesis. If fertilizer is applied, dormancy will soon be broken, causing plants to continue to grow, which will consume more nutrients and affect flowering in the coming year.

Fourth, do not apply thick fertilizer. Potted flower fertilization, the concentration should not be too large or too much, otherwise it will cause death. Generally speaking, we should grasp the principle of applying thin fertilizer frequently, and it is appropriate to use three parts of fertilizer and seven parts of water.

Fifth, do not apply raw fertilizer. If unripe fertilizer is used, it is not only easy to produce worms and maggots, but also often gives off a stench and pollutes the environment, and will ferment in the presence of water, harming the roots of the plant.

Sixth, not only apply nitrogen fertilizer. Flowers should be fertilized with nitrogen, phosphorus and potassium, preferably with cake manure, barnyard manure, compost and other farm manure.

Seventh, the sick and weak plants should not be applied. The branch of the diseased and weak plant is thin, the photosynthesis is poor, the metabolism is slow, the deficiency is not replenished, if fertilized, it is easy to cause fertilizer damage.
