Usage of water retaining agent

Introduction: water retaining agent is non-toxic and harmless It releases and absorbs water repeatedly, so people in agriculture compare it to "mini reservoir" So, how to use water retaining agent? Come and have a look with you! The function of water retaining agent is not only to absorb and store water, but also to conserve soil, fertilizer, increase production, improve soil matrix environment, improve soil hardening, textile soil erosion and so on So, how to use water retaining agent? Let's introduce the small edition of Baibai safety net! There are four most commonly used methods of water retaining agent: dip root method: it is to evenly dip the root system of plants with the paste liquid made of water retaining agent The root dipping method is mainly used in transplanting vegetables, flowers and seedlings with bare roots Generally, a kilogram of water retaining agent can treat at least 2000 seedlings With this method, the survival rate of fixed plantlets can be increased and the delay time of seedling can be shortened Mixing soil method: mixing soil method is to mix the water retaining agent and soil in a certain proportion, and apply it into the cultivation ditch or hole Mixing soil is to make the water retaining agent evenly distributed around the root system of plants, which is the most widely used method at present It can be used in sowing, seedling planting, potted flower planting, tree planting and substrate seedling raising When the seedlings are raised in vegetable, flower and other crop substrates, the water retaining agent and the seedling substrate can be mixed and stirred at the ratio of 1:100, put into the seedling tray, and then put the seeds into the tray for watering Seed dressing and mixing fertilizer method: seed dressing with water retaining agent is also called seed coating or seed coating It can form a hydrogel like protective film on the surface of seeds to be seeded The selected water retaining agent is usually of small particle type, or seed dressing powder Seed dressing can improve the emergence rate, save labor and facilitate mechanized operation The specific method is to mix the seed powder and water in proportion to 1:100, and put it in a steady state for about 3 hours After being all hydrogel, pour the seeds into it, stir it well, mix it evenly, and put it in a cool place for 4-6 hours The mixing proportion of water retaining agent and seed is subject to the product instructions, generally around 1:500 Take corn as an example, each kg of water retaining agent can mix about 500 kg of corn seed Soilless culture: water retaining agent can also be used as soilless culture medium, also known as crystal mud Its type is mainly polyacrylamide, the shape of circular particles, irregular particles, a variety of colors, its products are colorful It is mainly used for ornamental gardening The flowers cultivated with crystal mud are suitable for placing at home or in the office The use of crystal mud is very simple First, select a transparent glass container for planting flowers, take a certain amount of crystal mud particles, soak the crystal mud particles with clear water for 3-4 hours, after all the absorption, take 2 / 3 of the crystal mud into the glass container, then transfer the root washed flowers into the plant, and finally pour the remaining 1 / 3 of the crystal mud into it Pay attention not to have too much water in the container, and avoid direct sunlight when placing the vase The above is a small edition for you to introduce the use of water retaining agent some of the content, I hope to help you oh!
