There are roughly the following reasons why dragon fruit produces a large number of aerial roots:
1. Insufficient nutrition requires the use of aerial roots to absorb water and nutrients.
2. The climate is suitable, moist and rainy, plant climbing habits, long air rooting.
3. Instable growth requires the use of aerial roots to stabilize the plants.
Comprehensive analysis:
On the one hand, the root of aerial growth is the gene that inherits the climbing growth of dragon fruit. It grows at the end point of the young shoot of the plant to climb on the host and plays a fixed role. On the other hand, field observations show that the plant grows stronger and has shorter rooting. There is a certain relationship with the lack of nutrition.
It was observed that, after the rainfall has cooled, the roots of aerial roots emit white roots that can absorb certain nutrients. Moreover, the roots of aerial roots have emerged. How should different cultivation methods be used?
Column type planting: place a certain height above the ground through the drip irrigation pipe (above the aerial roots), use aerial roots to absorb nutrients when drip irrigation to remove fertilizer;
Row planting: aerial roots mostly grow at the junction with bamboo rafts. As a result, the tip of the mother branch can be used mainly for normal use, and the application of foliar fertilizer or root absorption can be better. effect.

L-serine, as a basic amino acid of protein, is widely used in medicine, food, cosmetics and other industries. At present, the global market demand for L-serine is 10000t / A. L-serine is a non essential amino acid, which is an important precursor involved in the synthesis of intracellular biological substances such as purine, pyrimidine and phospholipid. L-serine is a raw material for compound amino acid infusion, and can also be used as a raw material for light chemical industry . In addition, L-serine is widely used in advanced cosmetics at home and abroad because of its special wettability and moisture retention
D-serine is one of the most important D-type amino acids in mammals, which is about 1 / 3 of the total free serine. It has been found that high concentration of D-serine exists in the higher center of higher animals, including human beings, and it plays an important role in neurotransmitter. It is found that D-serine plays an important role in the corpus cavernosum and lower esophageal sphincter of mice.
