探索在不同酸度条件、不同种植制度下进行酸化防治的适宜石灰用量和施用方法,为全面开展“一斤石灰一斤粮”增产行动提供技术指导依据。试验结果表明:在PH5.0的酸性土壤中每亩施用50公斤石灰的增产效果最为显著,其增产途径是通过改良土壤,提高作物的结实率和千粒重来实现。
Explore the different acidity conditions, different planting system for acidification prevention and control of lime dosage and application methods for the full implementation of “a pound of lime a pound of grain” to provide technical guidance to increase production. The results showed that applying 50 kg of lime per acre in PH5.0 acid soil was the most effective way to increase yield, which was achieved by improving the soil, increasing the seed setting rate and 1000-grain weight.
