Abstract

The invention belongs to the field of agricultural waste cyclic utilization, in particular to a degradable seedling culturing bowl prepared with straw and a preparation method thereof. The degradable seedling culturing bowl prepared with the straw is prepared with, by weight, 50-100 parts of sweet potato straw, 50-100 parts of wheat straw, 50-100 parts of soybean straw, 50-100 parts of cotton straw, 5-10 parts of astragalus membranaceus herb residues, 1-5 parts of isatis root residues and 0.2-2 parts of addition agents. The seedling culturing bowl is good in water storage performance and medium in blow wall strength, unshelling is not needed after seedlings culturing is completed, the bowl is not harmful to roots and seedlings, the seedlings in the bowl are convenient to transport, integrated transplantation is facilitated, the bowl can decompose in soil naturally, no pollution is caused to the soil, and a certain fertilizing effect is achieved.

Description

technical field [0001] The invention belongs to the field of recycling agricultural waste, and in particular relates to a degradable seedling pot prepared from straw and a preparation method thereof. Background technique [0002] Straw fiber is one of the huge regenerative biopolymer resources in nature. The annual output of straw fiber in the world is about 40×10 tons, and the annual output of straw resources in China reaches 790 million tons. People pay more and more attention to the huge waste of resources and serious environmental pollution caused by burning or burying straw. At present, there have been many reports on the utilization of straw, such as fertilizer, new energy, animal feed, degradable material, base material for cultivating edible fungi, and building material. [0003] Patent CN104025945A discloses a degradable seedling pot and a production method thereof. The seedling pot uses biopesticide fermentation residue as the main raw material, adds some straw p...
