Key points of bonsai hydroponic culture techniques what are the methods of hydroponic culture

In order to cultivate excellent new varieties, it is necessary to choose both excellent male parents and good female parents, so as to produce a new generation of excellent varieties. Magnolia is a heterozygote, genetic is more complex, the seeds in the same fruit, often there are great differences, good flowers give good powder, treasures, the probability of the emergence of fine goods is also very small. Some seedlings begin to grow well and lose their state when they are young. On the other hand, some seedlings have 1-2 leaves that are not very good, but they gradually get better after growing a few leaves, that is, the outcome of good flowers and good pollination is not the same as that of secondary flowers.

The technical problems in the cultivation and management of Cymbidium are the key to determine the good growth and development of the plant. here are the key points of bonsai hydroponics:

Container selection:

In order to carry out hydroponic culture of Cymbidium, we should first choose a good container. Generally speaking, it is better to use a transparent glass container. If you raise a seedling, you only need a glass can. If you want to plant a lot of water, you can use fine wire to compile a metal mesh with a diameter of one centimeter, and make a glass hydroponic box slightly smaller than the metal mesh, or you can use a goldfish tank instead. Then the metal net was covered on the hydroponic box, and the seedlings of Cymbidium were inserted into the nutrient solution through the mesh, and the depth of the flower root in the culture medium did not exceed the limit of the false bulb of the root.

Preparation of nutrient solution:

Nutrient solution is divided into inorganic and organic. The inorganic nutrient solution can be prepared according to the following proportion: 1.5g of calcium, 0.01g of ferrous sulfate, 1g of urea, 1g of potassium dihydrogen phosphate and 0.5g of magnesium sulfate. After the above five inorganic salts are mixed together, they can be dissolved in 1000 grams of water. The organic culture solution was prepared as follows: fried flax seed flour 100g, bone powder (made of salt-free fresh bone) 100g, bean cake powder 150g, cooked sesame powder 50g, and then dissolved in 1000 grams of water. Compared with the above two kinds of nutrient solution, the composition of organic fertilizer is rich, but the nutrient content is not high, and the composition of inorganic fertilizer is relatively simple, but the fertilizer effect is high and the effect is fast. In order to learn from each other's strong points to offset their weaknesses, the two can be used together. If used alone, inorganic fertilizer is applied once a week, and organic fertilizer is applied once every 5 days.
