How to identify edible mushroom diseases? Flower nutrient solution should be prepared like this

In flower cultivation, using solid fertilizer not only makes the dosage difficult to control, but is also rather troublesome. If liquid fertilizer is used, using nutrient solution to grow flowers is both convenient and effective.

Introduce several commonly used nutrient solution formulas and their methods of use. The most widely used flower nutrient solutions include the following two: (1) Potassium nitrate 0.7 g/L, boric acid 0.0006 g/L, calcium nitrate 0.7 g/L, manganese sulfate 0.0006 g/L, superphosphate 0.8 g/L, zinc sulfate 0.0006 g/L, magnesium sulfate 0.28 g/L, copper sulfate 0.0006 g/L, ferric sulfate 0.12 g/L, ammonium sulfate 0.0006 g/L. Method of use: when using, mix the various compounds together, add 1 liter of water, and it becomes nutrient solution, which can be poured directly on the flowers. When the amount used is large, mix in proportion and use as needed. (2) Urea 5 g, potassium dihydrogen phosphate 3 g, calcium sulfate 1 g, magnesium sulfate 0.5 g, zinc sulfate 0.001 g, ferric sulfate 0.003 g, copper sulfate 0.001 g, manganese sulfate 0.003 g, boric acid powder 0.002 g, add 10 liters of water, and after full dissolution it becomes nutrient solution. Method of use: during the growth period of potted flowers, water once a week, with the amount used each time depending on the size of the plant; for sun-loving flowers, about 100 milliliters each time, while for shade-loving flowers reduce accordingly. In winter or during the dormant period, once every 1 month. For ordinary watering, still use tap water.

Notes on preparing nutrient solution: 1. Use glass, enamel, ceramic and other containers to prepare nutrient solution, and never use metal containers. 2. When preparing, first use a small amount of warm water at 50°C to dissolve each element separately, then pour them into the water, stirring while pouring, and mix fully. 3. When using tap water to prepare nutrient solution, a small amount of humic acid compounds should be added to treat the chlorides and sulfides in the water; in rural areas, river water or lake water can be used directly for preparation.
