Superabsorbent 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. |
