盐碱地种植水稻要获得高产、稳产,关键要抓好改良土壤、防止碱害这一技术环节。尤其是秧苗抗盐碱能力很弱,当土壤pH>7时,就会使苗期立枯病大发生。因此,盐碱地旱育秧必须育出壮苗、健苗,为丰产打下坚实基础。 In order to obtain high yield and stable yield for planting rice in saline-alkali soil, the key point is to improve the soil and prevent alkali damage. In particular, the capacity of salt-resistant seedlings is very weak, when soil pH> 7, it will make the blight at seedling stage. Therefore, saline-alkali dry nursery seedlings must grow strong seedlings, Jianmiao, lay a solid foundation for high yield.
