Understand how to cultivate edible fungi and how to prevent orchids from catching arrows.

The clip arrow refers to the phenomenon that the arrow can not come out when the arrow is drawn and blossoms in the tower. We should find out the cause of the entrapment of the arrow and solve it in a targeted manner.

One is to adjust the temperature. The optimum temperature for the growth of Cymbidium is 15-25 ℃, if it is lower than 15 ℃, it is difficult to draw flowers and arrows, and if the temperature is higher than 25 ℃, it is not conducive to drawing arrows. Low temperature can put the flowerpot on the radiator, the bottom of the pot with a thin board, so that the temperature is not more than 25 ℃; if the temperature is too high, the flowerpot can be placed 1 meter in front of the fan to cool down.

The second is to increase nutrition. The flowering period of Magnolia needs more phosphorus and potash fertilizer, so the partial application of nitrogen fertilizer and the lack of phosphorus, potash fertilizer and trace elements will affect the arrow flowering. The frequency of fertilization should be increased in autumn, and it is best to apply liquid fertilizer with high phosphorus content. It is found that the arrow outcrop should spray 0.3% potassium dihydrogen phosphate solution to the leaf.

The third is moderate watering. More water is needed in the arrow drawing stage, if there is a lack of water at this time, it will not only affect the arrow drawing, but also make the leaves shriveled, withered, sagging and curling and so on. Should pay attention to increase the amount of water, it is best to pour magnetized water every 3-5 days, the amount of water should not be too large, but must not let the basin soil dry thoroughly, so as not to cause arrows to affect flowering.

In addition, when the pressure of the leaf sheath and false bulb is too high, it will also make the stem of the arrow unable to escape inside. A sterilized blade can be used to cut the leaf sheath of the arrow by 1-2 cm to reduce the pressure and promote the extraction of the arrow. (source: rural public)
