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.Retaining agents most commonly used, such as mixed use, mixed with soil.
( 1 ) 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.
At the time of planting seedlings of fruit trees, gardens, water retention agent should use granular potassium polyacrylate, each tree fertilizer 20-50 G, trees, small trees less. Also mix well with dry soil, applying tree bottom, planted trees, fill, compacted, water permeable. Needs to pay attention in the tree to form a ring around the Groove in order to collect rainwater, planted trees with this approach later without artificial irrigation, natural rainfall alone will ensure its growth. Fruit on water of demand big, best each across three years Chase Shi once insurance agent, we selection big particles polypropylene n amine type insurance agent, in Chase Shi insurance agent Shi, along Crown projection at dug a article ring ditch, also can dug 5 article to trunk for Center of radiation-like Strip ditch, long to Crown of projection edge, wide for 10-15 cm, depth to show part root for associate, Super absorbent polymers application into the trench, and the bottom 10 cm of the soil mix, after sufficient irrigation ditches fill compaction, a dimple-shaped top to collect rainwater. If the fertilizer and topdressing, best fertilizer on top of the water retaining agent, so that the maximum benefit is that you can prevent the leakage of fertilizers, improving fertilizer use efficiency. Using water retaining agent can not only improve the survival rate of trees, can also increase the fruit of fruit trees, so as to achieve the purpose of increasing yield and income.
( 2 ) 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.
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, 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.
