How to use potassium dihydrogen phosphate on flowers?

The method of using potassium dihydrogen phosphate on flowers:

1. Seed soaking and seed dressing: it can stimulate seed germination and promote seedling strength, making its stem stout, tall and straight and resistant to lodging. Soak seeds: every 100 kg of seeds with 200 grams of potassium dihydrogen phosphate, 50 kg of water, soak seeds for 12 to 16 hours, remove shade to dry. Seed dressing: every 100 kg of seeds with 200 grams of potassium dihydrogen phosphate, 10 kg of water, mix well with the seeds.

2. Dipping roots: before transplanting flowers and trees, use 0.4 to 0.5 kilograms of potassium dihydrogen phosphate per mu, mix well with dry and fine soil, add water to make pulp, and dip in the root when transplanting. A week after the daffodil was launched, the daffodils sent out tender leaves, and fibrous roots have grown at the base. They can be soaked in 0.1% potassium dihydrogen phosphate solution instead of water for one day a week to promote the width of the leaves and the fragrance of flowers.

3. Foliar fertilizer spraying: the foliar surface is often sprayed with 0.3% potassium dihydrogen phosphate solution during the growing period, which can make the branches strong and leaves luxuriant and flowers colorful. Herbaceous flowers, such as a string of red, petunia, dahlia, etc., can be sprayed with 0.3% potassium dihydrogen phosphate solution 2 to 3 times in the bud stage to make the flowers large and colorful.

4. Prepare nutrient solution: use 3 grams of potassium dihydrogen phosphate, 5 grams of urea, 1 grams of calcium sulfate, 0.5 grams of magnesium sulfate, 0.001 grams of zinc sulfate, 0.0003 grams of ferric sulfate, 0.0001 grams of copper sulfate, 0.003 grams of manganese sulfate, 0.002 grams of boric acid, and 5 kilograms of water. The peanuts in the pot should be irrigated once a week for a long time, and the dosage can be determined according to the plant size. For example, the positive flowers with a diameter of 20 cm in flowerpots should be watered about 100 grams each time, while the amount of flowers that like yin should be slightly reduced. In winter or dormant period, irrigate once every half month or one month.

Precautions for the use of potassium dihydrogen phosphate on flowers:

1. Foliar spraying (notice that both sides of the leaf should be sprayed) is the most commonly used method, which absorbs directly into the plant from the leaf stomata to make up for the lack of phosphorus and potassium nutrients, can enhance photosynthesis, prevent plant premature senescence, strengthen leaves and roots, improve resistance to low temperature and high temperature, promote the synthesis and accumulation of starch and sugar, and promote the formation of anthocyanins. Generally speaking, the effect of spraying and pouring before the bud period is better. Note that it is not applied in rainy days and at noon in sunny days; it is better to apply fertilizer before 10:00 in the morning and after 4 o'clock in the afternoon, and the effect is also good when properly mixed with aspirin in March and April.

2. If you want to increase the seedling rate, apply this medicine more often in winter (3-5 times, 10 days apart); if you want the flowers to bloom more and bloom well, apply this fertilizer every 10 days from July 10 to August 10, which is especially effective for grasses that haven't flowered for years.
