硼是一种微量元素,对各种植物的生长发育都有作用。在小麦生育各个时期,对叶面喷洒硼溶液都有增产效果。实验证明,水地小麦返青期喷硼,增产18％左右;分蘖期喷硼,增产20％左右。旱地小麦在返青期喷硼,增产也达13.4％左右。在孕穗至抽穗期喷硼效果更好,有的小麦增产高达20％以上。硼不仅提高了小麦籽粒产量,而且也提 Boron is a trace element, a variety of plant growth and development have a role. In all stages of wheat growth, spraying boron on the foliage has the effect of increasing yield. Experiments show that the return of water to wheat boron spraying, an increase of about 18%; tillering boron, an increase of about 20%. Dry land wheat in the greening period boron, yield also reached 13.4%. In the booting to heading boron spraying better, and some wheat yield up to 20% or more. Boron not only raises wheat grain yield, but also mention
