杂交水稻种子煤灰渗调技术四川省绵阳市第二种子公司杨荣合杂交水稻制种按传统的技术浸种催芽,种子发芽率低,出苗不整齐,不易培育壮秧。因此,宜采用煤灰渗调技术。1煤灰渗调的原理煤渣(灰)容重为0.7,总空隙度54.75%(大孔隙度21.75%,小孔隙度33...
Hybrid rice seed ash seepage transfer technology Mianyang City, Sichuan Province, the second subsidiary Yang Ronghe hybrid rice seed germination by traditional techniques of germination, seed germination rate is low, irregular emergence, difficult to cultivate strong seedling. Therefore, it is advisable to use coal ash permeation technology. A principle of coal ash seepage control Cinder (ash) bulk density of 0.7, the total porosity 54.75% (large porosity 21.75%, small porosity 33 ...
