The invention discloses a mixing device for preparing an atriplex canescens cultivation substrate and the cultivation substrate, the device combines
powder spraying, rolling and stirring, the stirringefficiency is improved, the mixing sufficiency is facilitated, and the uneven mixing caused by directly adding a small amount of
powder into a large amount of basic substances is avoided. The cultivation substrate is prepared from the following raw materials in parts by weight: 30-90 parts of a
humic acid mixture, 30-70 parts of
peat, 40-80 parts of sand, 10-40 parts of
vermiculite, 0.8-2.0 partsof
chitin, 5-10 parts of
polyacrylamide, 0.5-1.0 part of Pujuxitang, 0.1-0.5 part of a dispersing agent, 0.2-0.4 part of a
wetting agent, 0.1-0.5 part of white
carbon black and 1-3 parts of inorganiccarrier. The culture medium provided by the invention is mainly prepared from
peat, sand,
vermiculite and the like, is good in air permeability, strong in
water retention capacity and rich in nutritional ingredients, and is beneficial to enhancing the
autoimmunity of the atriplex canescens, reducing the infection of
bacteria on the atriplex canescens, improving the
survival rate of the atriplex canescens and promoting the growth of seedlings by combining the characteristics of nano
chitin, methanesulphonamide and Pujuxitang. And a good foundation is laid for
cutting seedling of the atriplex canescens.
