COMPARISON OF PLANT FOOD
We prepare three variants of the conditioner described on the right. We put one plant in a solution that contains all the ingredients, the other in a nitrogen-free nutrient solution (we give calcium chloride instead of calcium nitrate), the third in the conditioner without sulfur (we give magnesium chloride instead of magnesium sulfate). Place the fourth plant in tap water, and the fifth in distilled water. We germinate the seeds on blotting paper (on the right) before placing them in test tubes. We write down differences in growth.
The composition of the conditioner
10 g of calcium nitrate
2.5 g of potassium phosphate
2.5 g of magnesium sulfate
2.5 g of potassium nitrate
A pinch of iron chloride 1 dcm of distilled water
1. Carefully cut or tear off a twig or a piece of shoot from the mother plant. She must look strong and healthy. We immerse its end in the rooting agent.
2. We put in a pot, burying the cut in the ground. We keep warm, shade and moisture. If we prepare a lot of seedlings, we can use a multiplier to keep the air moist and warm. Then we transfer them to compost soil, taking care, so as not to damage the rootlets.
Grafting in a wedge
1. We select a scion with a thickness such as the washer and cut it in the form of the letter "V”.
2. Fold the scion tightly to the rootstock and tie it with wet raffia.
3. After binding, leave in a warm place.
Vaccination for the bark (sheepskin)
This method can be used with fruit trees, grafting several scions on one rootstock.
1. We cut the bark and put a scion under it.
2. We cover the vaccination site with raffia and spread it with garden ointment.
1. Use a sharp knife to cut the eyelet with a piece of bark.
2. Carefully make a T-shaped cut on the root of the rootstock”.
3. We put the eyelet into the gap and tie the whole thing together.
Vaccination by rapprochement
1. We remove the bark strips from the rootstock and scion yes, to fit together.
2. We fold the cuts together, tying carefully.
3. We cut off the upper part of the rootstock and the lower part of the scion.
Taking consecutive photos
By taking pictures at regular intervals, we will record the growth of the plant. Checkered paper as a background will make it easier for us to make measurements of height. The photos are pasted in the right order.
