IRRIGATING 50-150 g watered 50 kg evenly watered crop roots. Soaking 100 g watered 50 kg Soaking 12 hours, remove and dry seeding, the solution can be administered. 10 kg 100 g watered dressing splashed on the seed mix, dry after use. Note: should choose at 10:00 before 16:00 after spraying. It can be mixed with acidic, neutral pesticide application, increasing efficacy, can not be mixed with alkaline substances. This product is a water soluble fertilizer, instant water, please store in a cool dry place. After opening the bag, please do not use the seal. Potassium dihydrogen phosphate fertilizers, it is important to growth regulators, and its main role are the following: 1. Chlorine-free, low salt index, soluble in water. Rich in phosphorus and potassium nutrients, safe, non-toxic, does not go far failed. 2. Can buffer changes in soil pH, soil pH stable. Flowers can promote growth and reproduction of rhizosphere microbial flora. Can improve the soil, so that flowers developed root system, hypertrophy dark green leaves, thick stems, disease resistance, stress tolerance increased. 3. Absorption when used in foliar application rates as high as 80-90%, can regulate the growth of flowers, the nutritional supplement at a critical time. On some flowers applied, can significantly extend the shelf life to improve the quality of transport, making it suitable for use on cut flower production. 4. With less, the effect is obvious. Potassium dihydrogen phosphate, potassium ions and phosphate ions, can be directly absorbed flowering plants use, the effect is quick and obvious. Potassium dihydrogen phosphate in common use on flower production methods are: 1, soaking, seed dressing: to stimulate seed germination and seedling promote strong, it stems stout, erect lodging. Soaking: 100 kg seeds per 200 g of potassium dihydrogen phosphate, 50 kg water soaking 12-16 hours, remove and dry. Dressing: 100 kg seeds per 200 g of potassium dihydrogen phosphate, water 10 kg, with a seed mix. 2, dipping: Before transplanting flowers and trees per acre with potassium dihydrogen phosphate from 0.4 to 0.5 kg, and dry fine soil mix, add water, slurried in transplanting dipping planting. Daffodils in the water after a week, the ball will be issued narcissus leaves, the base has grown fibrous roots, can a week with 0.1% potassium dihydrogen phosphate solution instead of water immersion l days, prompting its leaf width, floral. 3, Yemianpenfei: 0.3% in the growing season often foliar spray of potassium dihydrogen phosphate solution, enabling strong leafy branches, flowers and more Seyan. Herbs such as a bunch of red flowers, petunias, dahlias, etc., in the budding stage sprayed 2-3 times a 0.3% solution of potassium dihydrogen phosphate, can make flowers large and more colorful. 4, the preparation of the nutrient solution: 3 g potassium dihydrogen phosphate, 5 g of urea, 1 g of calcium *, * 0.5 g of magnesium, zinc * 0.001 g, 0.0003 g * Iron * Cu 0.0001 g, 0.003 g * manganese borate, 0.002 g, 5 kg of water, dissolved Serve nutrition. Pouring a flower growing in the week, the amount of time according to plant size. For example, the inner diameter of 20 cm pots hi positive flowers, each poured about l00 grams, and the amount of shade flowers should be diminished. Winter or dormant period, each half or one month pouring 1. Foliar spray (note the leaves should be sprayed on both sides) is the most common method, the absorption lines from the leaf stomata directly into the body, to compensate for the lack of phosphorus and potassium nutrients, can enhance photosynthesis, plants to prevent premature aging, Zhuang Zhuang Ye roots, improve the low temperature, high temperature resilience, promoting starch accumulation of sugar synthesis, promote the formation of anthocyanins. General before bud of spraying and watering better. Note that is not applied in the rain, sunny noon not applied; should select at 10:00 before 16:00 better after fertilization, proper incorporation in January 1000 at 3.4 administering aspirin effect is also very good. If you want to improve sprouting rate, then in the winter Dorsch this drug (3-5 times, every 10 days); much if you want flowers, open well, then please at July 10 through August the 10th applied once every 10 days this fat, but not for many years to spend the grass is particularly effective. Usage: watered 1: 1000. Irrigation or foliar spraying with an aqueous solution of potassium dihydrogen phosphate. To do so, have the following effects: one, enhanced resistance potted flowers. Potted flowers capacity due to soil nutrients less high temperature and low humidity in the summer season, a day sooner or later a lot of watering to prevent dry, but excessive watering and watering too often can lead to a pot of nutrient loss, resulting in a variety of poor growth conditions . If every week, pouring a concentration of 0.2% aqueous solution of potassium dihydrogen phosphate, can reduce the amount of water to prevent nutrient loss, but also enhance the resistance of flowers. Tricolor Dong, petunia, marigold flower pots, etc. on the late autumn, foliar spray once per week, with a clear cold resistance; impatiens, summer pansy, zinnia and other summer and fall flowers, watering per week once, can enhance its drought resistance; Marginata, camellia, Milan and other woody flowers, take root and foliar spray irrigation combination, can prevent anthrax, Sooty mold and mildew root infection. Second, make stocky of potted flowers. Potted flowers require growth height and size of pots with suitable, dry stems should not grow too high, so as not to affect the display on the balcony. Dahlia (Dahlia), hollyhock, high poinsettia flower stems, commonly potassium dihydrogen phosphate watering can make short and robust stems, the flowers are much larger; Verbena, Dianthus class, using the same method, "not only stems grow stout, but not lodging; Wallflower and senior cadres shaped cockscomb, poured root and foliar spray with a combination of approaches, both the individual plant dwarfing, and reduces leaf growth and make flower-shaped large And strange Third, extend flowering. shorter flowering potted flowers, mostly small pots of soil nutrients due to capacity, lack of potassium, phosphorus and other trace elements caused, especially for potash responsive flowers, due to lack of Potassium appeared fragile stems, less buds, flowers wither and not very bright and easy symptoms such as its strategy is through irrigation with potassium dihydrogen phosphate solution on the flower pots pots when the seedlings after foliar spray once every two weeks. according to In this way, pansy, petunia, such as the basin in October, November will bloom from February to May the following year are flowering; hibiscus, Milan, white orchids, camellias, etc., when in bud formation, spraying potassium dihydrogen phosphate, bright flowers can extend the period 5-7 days; auspicious grass, evergreen, foliage plants such as big-leaf Sedum, pouring over 3-4 times a potassium dihydrogen phosphate, also make outstanding stout stems, have mosaic . ornamental value and Mao formulated aqueous solution of potassium dihydrogen phosphate, watering with 0.2% concentration is appropriate depending on the growth stage of foliar spray of flowers will have to be: the seedling stage to 0.1%, with 0.2% of the stalk forming appropriate. as basal concentration was 0.5%, the pots of mud mixed with moist under basal if pot was full, with chicken manure, composting mix of ash mixed with clay pots, clay pots that will not potassium; If not because of Watering too much loss of nutrients, not to be watered or less pouring potassium dihydrogen phosphate. dihydrogen phosphate only as a supplement nutrients flower, must be applied in other fields as a nutrient foot situation, will have a significant effect.
