Range of application
云南11选5开奖结果Used on agriculture and forestry soil water retention, soil, crops, soil-less planting, seed, nursery stock transplanting, dip, fertilizer additives and so on
Super absorbent polymers on soil water and crop growth of related not only to water absorption and water holding capacity and soil texture, rainfall, irrigation and crop species and so on.
云南11选5开奖结果 Dip use retaining agents most commonly used root, seed, soil mixing, soil-less cultivation, seed sowing, spreading and wait.
( 1 ) Dipping method
Is the root system of the plants evenly coated with Super absorbent polymer into liquid paste. Dip the root method, mainly in vegetables, flowers and seedling of naked root transplanting time.
When the vegetable seedlings, as vegetable growing season is shorter, we can choose the short life of the small particles of water retaining agent. Specific methods of operation: first transplanting a whole, dig planting seedlings points in its hole by constant applied phosphate fertilizer as basal, ready for transplanting seedlings, then dipped in liquid preparation. In preparation dipped root liquid Shi, to increased dipped root liquid of dip to, makes root Shang easy hanging Shang more of dipped root liquid, we can will insurance agent and fine dry soil by must of proportion mixed uniform, then again according to products of using description by proportion joined water, insurance agent and water of proportion roughly for 1:300, side added side constantly mixing, makes its full sucking water, mix Hou static reset 3 hours after water absorption of Super absorbent polymers, such as a mud paste. Dip roots the roots of seedlings into the dip solution, roots to try to hang up the dipping liquid, so it can be planted. Attention when planting seedlings in real land around the seedlings, seedling roots could maintain close contact with the soil, planted seedlings time after water flooded. A kilogram of water retaining agent can handle at least 2000 seedlings. In this way, you can improve the survival rate of planting seedlings, shorten the slow time.
In a small tree when transplanting, when dipped in liquid preparation of seedlings of preparation method of the same, only when you select a Super absorbent polymers, our best selection of potassium polyacrylate, because the tree grows long, most of the trees rely mainly on natural rainfall, water supply conditions are relatively poor, so you should use long life, repeated water-absorbing function of Super absorbent polymers. In addition, bare-root seedlings for long distance transportation easily lose water, dip in with Super absorbent polymers, can give seedlings to add water to prevent water loss in the Middle, improve the survival rate of seedlings. Is in need of attention, and dipped water absorbent seedling roots had better wrap it with plastic film, loss prevention is better.
( 2 ) Fertilization method
Is Super absorbent soil according to a certain proportion of blending, turn it into ditches or cultivation hole. With soil in order to make water retaining agent can be evenly distributed around the plant roots, which is currently the most widely used method, in sowing, planting seedlings, potted plant planting, planting trees and seedling nursery can be used.
For the short growing season of annual crops, at the time of sowing or planting seedlings, we can choose a type of small particles, probably usage per acre 3-5 Kg, number of application specific product descriptions that can be used in accordance with the insurance agent. We take soil, soil can be directly selected field soil, attention to the fine soil, water retention agent and soil about 1:20 ratio blended together, stirring, making it uniform. At the time of application, sprinkle mix the good water retaining agent on seeding Groove or in the planting hole, and then applied the base fertilizer, top with a layer of soil after seeding or planting seedlings and water permeable. After applying this method can reduce more than half the watering frequency, improving the germination rate and seedling survival rate, at the same time, slow time significantly reduced. Vegetables, flowers and other crops when the seedling nursery, Super absorbent polymers and seedling can be 1:100 ratio mix, put inside a seedling into seed water permeable.
( 3 ) Seed
Super absorbent polymer seed also called seed or seed coating, it can be sowing seeds on the surface forming a layer of gel-like protective coating. Selection of Super absorbent polymers are usually s or m- particle type, or seed powder. Seed germination rate can be improved, convenient and conducive to mechanized operations. The specific method is: will mixing flour with water by 1:100 ratio mix, let stand 3 hours or so, pour the seeds after all become hydrogels full stirring, mixing evenly, put in the shade stuffy 4-6 hours Can be directly seeded or dried seeds. Super absorbent polymer seed and seed ratio is subject to product instructions for use, generally in the 1:500 or so, in maize, for example, each kg of Super absorbent polymers can be mixing corn seed 500 kg.
( 4 ) Mix fertilizer, fertilizer absorption method
Mix the fertilizer with water retaining agent can also directly. Mixed with fertilizer use can play a role in water and fertilizer. Operating method is: first use sprayers-Jet wet fertilizer, water and fertilizer by 1:10 ratio of full mix to make it even attached to each other. Is in need of attention, do not spray too much water in the fertilizer, so as to avoid chemical fertilizers knots faster, at the time of sowing plug feeding tubes if there are knots, used a shovel to smash it. Super absorbent polymer materials can also be invested in low-concentration solution of water soluble fertilizers, ensures that the Super absorbent polymer gel absorbs a certain amount of fertilizer, achieve the goal of sustained-release.
( 5 ) Of soilless culture
Soilless culture substrate for retaining agent can also be used as , Also known as Crystal mud. It is the main type of polypropylene acid potassium class, the shape of round granules, irregular-shaped particles, colors are varied, its products are colorful. Mainly used on ornamental horticulture, cultivation of flowers with Crystal mud, suitable for display in the home or Office. Crystal mud of using method is simple, first, selected good flowers of transparent glass container, take must volume of particles Crystal mud, will particles Crystal mud with clear blisters 3-4 a hours, all sucking rose Hou, take 2/3 of Crystal mud pour glass container in the, then will roots flush clean of spent transplant in, last put remaining of 1/3 Crystal mud poured into the can. Note containers which do not have too much water, vase placed to avoid direct sunlight.
( 6 ) With seeds sown below
When the dry season to plant crops, in order to save costs, generally uses the Super absorbent polymer seed sown under way, applied to planting trench (point) of water retaining agent to effectively protect crop seedlings to grow normally.
( 7 ) Strewn
Generally high cost of strewn water retaining agent can be used in planting perennial crops and lawns.
Super absorbent polymer mixed fertilizer to the soil, after absorbing water as the water is released slowly shrink, expand--contract will form a larger soil spaces, some space directly connected with the atmosphere and promote water exchange between soil and atmosphere, the respiration of the roots, but it will also cause some water loss. Application of water retaining agent in the process of expansion--contraction will also form a larger gap, but from the voids in the surface soil interval, weak water exchange with the atmosphere absorb and maintain, since it could maintain a higher moisture content. Pocketing the small contact area of water and soil, moisture holding capacity is small and too concentrated, relatively adequate inhibition of seedling in soil moisture, can result in poor soil aeration influence growth and survival. Some people think that applying superior application, the main reason is the excessive application of local soil moisture affects the normal crop emergence. Groove effect, pocketing, mixing effects of water retaining agent on soil depth distributions in different, determines the depth distribution of water layer in the soil. Application, pocketing over relatively deep water, applying relatively shallow. Application, pocketing absorb the moisture and keep not easy losing, applying the more vulnerable, with many experimental results of the Groove application, cave can increase soil moisture, promote crop growth are consistent. With spring temperatures of rebounded, soil water evaporation strongly, West southern coastal, area of soil easy has salt gathered surface, and tomatoes, crop not resistance salt, insurance agent can reduced evaporation, effective ease soil salt table set, for crop growth create a wet and low salt of soil environment, can more long time of maintained body water balance, keep growth vitality, promote root growth, and flowering fruit period suitable of soil water is high yield quality of key.
