basic method
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.
