摘要
以浙禾香2号为材料开展试验,探究不同锌肥施用对水稻产量、抗倒伏性、稻米品质及养分含量的影响.结果表明,S1W2处理(农户常规施肥基础上,基施锌动力2 kg/667 m2,并于分蘖期与抽穗期分别喷施戴乐锌400 mU 667 m2)效果最佳,稻谷籽粒产量达652.3 kg/667 m2,相比CF处理增产8.7％,植株的抗倒伏性、稻米品质和养分含量明显提升;喷施锌肥可显著提高籽粒的全锌含量.
Abstract
An experiment was conducted with Zhehexiang 2 as the material to explore the effects of new zinc fertilizer applications on yield,lodging resistance,quality,and nutrient content of rice.The results showed that the S1W2 treatment(on the basis of conventional fertilization by farmers,2 kg/667 m2 of zinc power is added to the base fertilizer,and 400 mU667 m2 of deloxin is sprayed at the tillering stage and heading stage respectively)had the best effect,with a grain yield of 652.3 kg/667 m2,an increase of 8.7％compared to the CF treatment(conventional fertilization by farmers),and a significant improvement in plant lodging resistance,rice quality,and nutrient content.Spraying zinc fertilizer could significantly increase the total zinc content in grains.
