用膨化机将稻壳膨化,使之成为易吸水、质地松软的膨化稻壳,再经过发酵,混拌到培育水稻秧苗的营养土中.这样做不仅可以增加培养土的有机质含量,而且能提高营养土的通透性,使之成为培育水稻壮秧的理想的营养土.小区试验和大面积生产证明:用稻壳营养土培育的水稻秧苗,根多、根长,根系发育好,叶片宽厚、挺直,抗逆性强,秧苗素质好.特别是在春季低温、多湿条件下,更显示其优越性. Puffing the rice hull with an expanding machine to make the puffed rice hull which is easy to absorb water and soft texture and then fermenting and mixing to cultivate the nutritious soil of the rice seedling so as to not only increase the organic content of the cultivated soil but also improve The permeability of nutritious soil makes it an ideal nutritious soil for cultivating strong seedlings of rice.The plot test and large area production prove that the rice seedlings cultivated with rice husk nutritious soil have more root and more root, , Upright, strong resistance, good seedling quality, especially in the spring low temperature, wet conditions, but also shows its superiority.
