在人工控制条件下,研究了生物吸水胶对土壤含水量的影响,胶土水分交换动态,吸水胶×肥料对土壤水分和苗木生长的影响,并进行了多地点大田育苗,造林和农作物试验。基本搞清了吸水胶吸水保水性能的特点。吸水胶用于育苗,造林和农作物的技术要点是:(1)育苗以每个容器(1株苗)0.3～0.7克为宜。苗木生长量增加10.18％～12.65％。(2)用于造林应当在整地后,先施吸水胶,待下雨后栽植。用量1～4克/株。施肥作业应先施吸水胶,待下过雨,胶吸足水之后进行。
Under artificial control conditions, the effects of biosorbent on soil moisture content, the dynamic changes of soil moisture exchange, the effect of superabsorbent x fertilizer on soil moisture and seedling growth were studied, and field nursery, afforestation and crop experiments were conducted. Basically figure out the characteristics of absorbent plastic water absorption and water retention. Absorbent plastic for nursery, afforestation and crop technology points are: (1) nursery each container (1 plant) 0.3 to 0.7 grams is appropriate. Seedling growth increased 10.18% ~ 12.65%. (2) For afforestation should be in the soil preparation, the first water gel, to be planted after raining. The dosage of 1 ~ 4 grams / strain. Fertilization operation should be applied to water plastic, to be under the rain, after the plastic suction full of water.
