The correct method for using monopotassium phosphate on flowers

Methods for using monopotassium phosphate on flowers:

1. Seed soaking and seed dressing: It can stimulate seed germination and promote strong seedlings, making the stems thick and sturdy, upright and resistant to lodging. Seed soaking: For every 100 kg of seeds, use 200 g of monopotassium phosphate, add 50 kg of water, soak the seeds for 12 to 16 hours, then remove and dry them in the shade. Seed dressing: For every 100 kg of seeds, use 200 g of monopotassium phosphate, add 10 kg of water, and mix thoroughly with the seeds.

2. Root dipping: Before transplanting flowers and trees, use 0.4 to 0.5 kg of monopotassium phosphate per mu, mix thoroughly with dry fine soil, add water to make a slurry, and dip the roots in it when transplanting. For narcissus, one week after being placed in water, the narcissus bulb sends out tender leaves and fibrous roots have already grown from the base. You can use a 0.1% monopotassium phosphate solution instead of clean water to soak it for 1 day each week, promoting wider leaves and fragrant flowers.

3. Foliar feeding: During the growing period, frequently spraying the leaves with a 0.3% monopotassium phosphate solution can make the branches strong and the leaves lush, with more flowers and brighter colors. For herbaceous flowers such as scarlet sage, petunia, and dahlia, spraying 2 to 3 times with a 0.3% monopotassium phosphate solution at the bud stage can make the flowers larger and more numerous, with vivid colors.

4. Preparing nutrient solution: Use 3 g of monopotassium phosphate, 5 g of urea, 1 g of calcium sulfate, 0.5 g of magnesium sulfate, 0.001 g of zinc sulfate, 0.0003 g of ferric sulfate, 0.0001 g of copper sulfate, 0.003 g of manganese sulfate, and 0.002 g of boric acid, add 5 kg of water, and after dissolving it becomes a nutrient solution. During the growing period of potted flowers, water once a week, and the amount used each time can be determined according to the size of the plant. For example, for a sun-loving flower with a pot inner diameter of 20 cm, water about 100 g each time, while the amount for shade-loving flowers should be slightly reduced. In winter or during the dormant period, water once every half month or once a month.

Precautions for using monopotassium phosphate on flowers:

1. Foliar spraying (note that both sides of the leaves should be sprayed) is the most commonly used method. It is absorbed through the leaf stomata and directly enters the plant body to make up for insufficient phosphorus and potassium nutrients. It can enhance photosynthesis, prevent premature aging of the plant, strengthen leaves and roots, improve resistance to low and high temperatures, promote the synthesis and accumulation of starch and sugars, and promote the formation of anthocyanins. Generally, spraying and watering before the bud stage have better effects. Note that it should not be applied on rainy days or at noon on sunny days; it is better to fertilize before 10 a.m. or after 4 p.m., and in March and April, appropriately mixing in 1/1000 aspirin also gives very good results.

2. If you want to increase the seedling emergence rate, then apply this fertilizer more in winter (3-5 times, with a 10-day interval); if you want the flowers to bloom more and bloom well, then please apply this fertilizer once every 10 days from July 10 to August 10. It is especially effective for grasses that have not bloomed for many years.
