摘要
硅是水稻生长的必需元素。试验表明,烟后稻(即烤烟后作水稻)施用硅肥,有利于其生长发育,增强水稻抗逆性,提高水稻有效穗,实粒数增多,千粒重增重,从而达到增产增收的效果。其关键技术是:于烟后稻拔节期前施用硅肥,施用量150～225 kg/hm2。
Silicon is an essential element for the growth of rice. The results showed that applying silicon fertilizer on post-tobacco rice could help its growth and development, strengthen resistant lodging, increase effective panicles, produce more filled grains, improve 1000-grain weight and finally achieve the effect of increased production and income. The key technique is to apply silicon fertilizer of 150 - 225 kg/hm2 before elongation stage of post-tobacco rice.
