由于干旱或种子发芽率不高,种植作物时经常出现缺苗断垄等情况。保证作物苗全苗壮是争取高产高效的前提条件。采用化学药剂在播前浸种或拌种是目前农业生产上常见的保苗方法之一。本试验旨在筛选促进种子萌发和根芽生长的有效药剂。1 材料与方法 本试验所用小麦品种为冀 3235.药剂分别为 1/100×黄腐酸盐、不同浓度的赤霉素
Due to drought or seed germination rate is not high, often lacking seedlings off ridge and other conditions when planting crops. It is a prerequisite for high yield and high efficiency that crop seedlings are fully sprouted. The use of chemicals before sowing seed or seed dressing is one of the common methods of seedling conservation in agricultural production. The purpose of this experiment is to screen for effective agents that promote seed germination and root bud growth. 1 Materials and methods The wheat varieties used in this experiment as Ji 3235. Pharmacy were 1/100 × fulvic acid, different concentrations of gibberellin
