【摘要】 成膜保水剂是一种新型土壤改良剂 ,通过其对作物的影响试验表明 :低 0 2 %PAA浓度的成膜保水剂对大多数作物的发芽有促进作用 ,提高作物的发芽率 ;0 2 %、0 4%PAA浓度的成膜保水剂对玉米的生长有促进作用。生产上应针对不同作物采用不同浓度的成膜保水剂更多还原

【Abstract】 water_conservating membrane is a new material of improving soil.Experiment indicated that 0.2% PAA of it can promote sprouting and increase sprouting rate of majority of crop.We found that appling 0.2% and 0.4% PAA density of water_swing membrane can promote the growth of maize.We shouid applying different density of the membrane according to different crop in agvicaltural prodution.更多还原
