Study On Rice Seedling Substrates With Edible Fungi Residue

Abandoned edible fungus industry in the north area of mushroom residue(black fungus mushroom residue and mushroom mushroom residue)on the basis of organic material,supplemented by grass carbon,organic and inorganic materials such as mud,fly ash,and through the nitrogen and phosphorus nutrition elements,study the alternatives to traditional rice seedlings of matrix of soil technology.The results show that:1.After a bunch of ripe black fungus mushroom residue and river mud in volume and mix after mixing,the cultivation of rice seedlings in plant height,leaf age,underground part and root dry weight,chlorophyll content were close to traditional soil seedling seedling quality.After adjusting the N and P nutrients in the matrix,it can be used for rice soil substrate seedling.2.Bacteria slag and coal ash according to volume ratio 7:3 and 8:2,preparation of rice seedling matrix formula produced by the good quality of rice seedlings from other mixed ratio,is a good substrate material combination to the infrastructure.After mixing the bacterial residue,grass carbon and coal ash 3 with 50%,30%and 20%(volume ratio),it was more beneficial to the growth of rice seedlings than the matrix of pure application of bacteria residue and coal ash.3.Nitrogen added matrix "black fungus mushroom residue,ash(7:3)+0.16%～0.23%N" can realize matrix of rice seedling,and in rice leaves and plant growth,root number increased and the earth(ground)is superior to the traditional soil seedling dry matter increase.4.Add in a single nitrogen to form the matrix formula of "mushroom residue,grass carbon and coal ash(5:3:2)+0.23%N)and with nitrogen and phosphorus removal added together to form the matrix formula of "mushroom residue,grass carbon and coal ash(5:3:2)+0.16%N+0.09%P205)"etc.for the rice seedlings in each of the indicators are better than traditional nursery soil,can be used as the matrix of the rice nursery production application.5.Different planting density on the substrate had a great effect on the quality of rice seedling,seedling quality increased with the increase of seedling dish in seeding rate(density),based on the matrix of black fungus mushroom residue in rice seedling best rate for 2～4 grains/hole,based on the matrix of mushroom mushroom residue of rice seedling best rate for 2～3 grain/den.
