Seedling-free tray straw degradable matrix block for rice dry seedling raising

Abstract

The application discloses a seedling-free straw degradable substrate block for dry rice seedling raising, comprising a substrate and a frame around the substrate that protrudes from the surface of the substrate; The lower surface is provided with a square protrusion corresponding to the cavity, and the shape of the cavity is matched with that of the protrusion; A "π"-shaped air channel is formed; the outer frame and the lower surface of the substrate are sprayed with a shaping layer film; the original frame structure of the substrate block of the present application can prevent the continuous sowing of rice seeds from spilling and the adhesion of rice seedling roots, and improve the volume of the substrate block. Blanket efficiency; the "π"-shaped airway structure can ensure the oxygen supply to the bottom of the substrate after the rice seeds in the concave root, and promote the formation of a gas-liquid-solid interface with the lower surface bulge, which has the functions of water retention and ventilation; the substrate block can effectively promote the rice Specialization, mechanization and scale of seedling raising and machine transplanting cultivation.

Description

technical field [0001] The invention relates to the related technical field of agricultural rice seedling raising matrix carrier and agricultural machinery for rice seedling raising, in particular to a seedling-free tray straw degradable matrix block for dry rice seedling raising. Background technique [0002] my country is the largest rice producer and consumer in the world, and more than 60% of the population takes rice as the main food. So far, my country's rice planting area has exceeded 20% of the world's total planting area, and the annual total grain output accounts for 1 / 3 of the global total grain output. With the transformation of planting patterns, rice planting is gradually developing towards standardization and scale. To achieve sustainable development of the rice industry, yield and quality are equally important. Seedling raising is the first step in rice high-yield cultivation technology, and is the basis for realizing high-yield and high-quality rice. [00...
