在盐碱地旱育水稻秧苗，偏高的土壤pH能降低报系活力，并促进有害微生物繁殖，抑制报系利2州市分的吸收，造成植株代谢紊乱，抗病性减弱。同时，在旱育秧过程中，给水量的减少常会导致降低水对好气性寄生苗的抑制作用，减弱水对土壤PH值的调节功能。因此，盐碱地种水稻旱育秧苗 In saline-alkali dry rice seedlings, high soil pH can reduce the viability of the reported lines and promote the propagation of harmful microorganisms, and inhibit the absorption of the reported phenobarbital subdivides, leading to the disorder of plant metabolism and the weakened disease resistance. In the meantime, in the process of drought nursery seedling, the decrease of water supply will often result in reducing the inhibitory effect of water on the aerobic parasitic seedlings, and weakening the regulating function of water on the soil PH value. Therefore, saline-alkali rice dry seedbed seedlings
