Biological seedling culture medium processed by papermaking sludge

Abstract

The invention provides a biological seedling culture medium processed by papermaking sludge. The biological seedling culture medium comprises 30-50 percent of papermaking sludge biological compost, 10-20 percent of pearlite and the balance of vermiculite in volume ratio; 1-2kg / m<3> of functional bacteria is added, wherein the proportion of the compost is 40-50 percent preferably when in large seed culture, whereas the proportion of the compost is 30-40 percent preferably when in small seed culture; in the papermaking sludge biological compost, the papermaking sludge is taken as the main material and wheat bran or crop straw is taken as the auxiliary material, and 2-3kg / m<3> of compost rapid zymophyte strain is added to be evenly mixed with the main material and the auxiliary material to prepare a mixture, wherein the moisture content of the mixture is 50-60 percent, and the C / N (Carbon / Nitrogen) ratio is 25-30. In the invention, the fully fermented papermaking sludge is adopted to serve as the substitute material of turf in the seedling culture medium to prepare the industrial seedling culture medium with low cost and sufficient nutrition through the reasonable proportioning. Cultured by the medium, seedlings have emerald green leaves, strong stems, developed roots and robust growth. The biological seeding culture medium can also effectively control the diseases in the seedling stage.

Description

technical field [0001] The invention relates to a seedling raising substrate, in particular to a biological seedling raising substrate processed with papermaking sludge. Background technique [0002] Compared with the traditional seedling raising method, the industrialized seedling raising method has the advantages of using less seeds and occupying less land; it can shorten the seedling age and save the time of seedling raising; it can reduce the occurrence of diseases and insect pests as much as possible; it can improve the production efficiency of seedling raising and reduce costs; it is convenient for unified management and new Advantages such as technology promotion, continuous production throughout the year. The rapid development of industrial seedling raising technology not only promotes the transformation of agricultural production methods, but also accelerates the adjustment and upgrading of agricultural industrial structure and promotes the process of agricultural m...

Problems solved by technology

However, since peat is a non-renewable natural resource, the transportation cost is also high, and there are defects such as insufficient nutritional stamina, it is imperative to find some new materials with low price and wide sources to replace the peat seedling substrate
