硼、镁是促进作物良好生长的微量元素。硼能显著提高作物授粉率,有利于种子形成,促进根系发育,增强抗灾能力,提高产量。镁是作物叶绿素的主要组成成分。宽甸县几年来的试验证明,玉米用1%的硼镁肥溶液浸种6小时,可提早3天出苗,平均增产10.3%;水稻、高粱、小麦在扬花期用0.8—1%溶液喷施,可早熟3—4天,平均增产5%;大豆和花生在花前喷1%的硼镁肥,提早成熟3天,平均增产4—5%,烟草在14—15片叶时喷1%浓度的溶液,叶宽和叶长均显著增加并提前开花,白菜在刚包心时喷0.6%的溶液,心包得紧实,比对照增产15%。作物喷硼镁肥既早熟又有较大幅度的增产效果。
Boron and magnesium are trace elements that promote the good growth of crops. Boron can significantly improve the rate of crop pollination, is conducive to the formation of seeds, promote root development, enhance disaster resilience and increase production. Magnesium is a major component of crop chlorophyll. Kuandian County trials over the past few years proved that corn with 1% solution of boron and magnesium fertilizer soaked 6 hours, 3 days earlier emergence, with an average yield of 10.3%; rice, sorghum, wheat flowering with 0.8-1% solution spray, Premature 3-4 days, with an average yield of 5%; soybean and peanut spray 1% before and after spraying boron and magnesium fertilizer, early maturity for 3 days, an average yield of 4-5%, tobacco spraying 14-15 leaves 1% concentration Solution, leaf width and leaf length were significantly increased and flowering in advance, cabbage in the heart of the heart just spray 0.6% solution, pericardium was tight, 15% more yield than the control. Crop boron fertilizers are both premature and more substantial yield increase effect.
