我们在中国科学院和河南农田灌溉研究所的帮助下,在郊区侯砦公社试验场和金海公社冯庄大队科研组进行了马铃薯滴灌试验。供试场地为粉砂质土,肥力较差;供试品种为高原7号、73—03、73—07和643,均以沟灌为对照。试验结果表明,在相同条件下,滴灌比沟灌可大大节省灌水,马铃薯的产量有显著提高。节省灌水:按每生产1斤马铃薯所耗水分的斤数计算,滴灌的耗
With the help of Chinese Academy of Sciences and Henan Institute of Farmland Irrigation, we carried out potato drip irrigation tests in the Houzhai commune pilot site in the suburbs and the research group of Fengzhuang Brigade, Jinhai Commune. The test site was silty soil with poor fertility. The tested cultivars were Plateau 7, 73-03, 73-07 and 643, all of which were ditched for comparison. The experimental results show that under the same conditions, drip irrigation can significantly save irrigation than furrow irrigation, potato yield has increased significantly. Save irrigation: According to the production of 1 kg of water consumed by the kilograms of water, drip consumption
