Embodiment 1
[0031] A method for raising rice seedlings without a tray, the method specifically includes the following steps:
[0032] (1) Mix nutrient soil and hydrosol according to the mass ratio of 3:2 to obtain a mixture of nutrient soil and hydrosol; the nutrient soil includes 10 parts by weight of chaff, 15 parts of sawdust, and soil 15 parts, 45 parts of livestock manure, 15 parts of fungus sticks; the hydrosol is purchased from the market, or processed by itself such as rice;
[0033] (2) Spread the above mixture evenly on the degradable non-woven fabric with a thickness of 4.5 cm. After the hydrogel at the bottom of the mixture is dried and bonded to the non-woven fabric, spread the rice seeds by printing sowing method On the surface of the mixture of nutrient soil and hydrosol, spray a small amount of water to wet the straw paper, and then evenly spread a layer of nutrient soil with a thickness of 0.5 cm to cover the seeds;
[0034] (3) After step (2) is completed, perform conventional...
Embodiment 2
[0036] A method for raising rice seedlings without a tray, which specifically includes the following steps:
[0037] (1) Mix nutrient soil and hydrosol according to the mass ratio of 3:2 to obtain a mixture of nutrient soil and hydrosol; the nutrient soil includes 12 parts by weight of chaff, 10 parts of sawdust, and soil 12 parts, 50 parts of livestock feces, 10 parts of fungus sticks; the hydrosol is purchased from the market or processed by itself such as rice;
[0038] (2) Spread the above mixture evenly on the degradable non-woven fabric with a thickness of 5.0 cm. After the hydrogel at the bottom of the mixture is dried and bonded to the non-woven fabric, spread the rice seeds by printing and sowing On the surface of the mixture of nutrient soil and hydrosol, spray a small amount of water to wet the straw paper, and then evenly spread a layer of nutrient soil with a thickness of 0.4cm to cover the seeds;
[0039] (3) After step (2) is completed, perform conventional seedling f...

Abstract
The invention belongs to the technical field of rice planting, in particular to a diskless rice seedlingraising method. The method comprises the following steps: evenlymixing nutritious soil andhydrosol, then laying on a degradable non-woven fabric, after the hydrogel in the bottom layer is dried and bonded with the non-woven fabric, sprinkling rice seeds on the surface layer of the nutrition soiland hydrosol mixture by a printing seeding method, spraying a small amount of water to weta straw pulp paper, and then evenly spreading a layer of nutrient soil to cover the seeds; carrying out conventional seedbed management, whenseedlings are 17-21cm high and grow 4.2-4.8 leaves, pulling outthe seedlings and planting by a machine. The method uses the mixture of nutritious soil and hydrosol as adiskless seedling raising substrate, which not only can meet the nutrient requirement for seed growth, but also has the advantages of loose substrate structure, good air permeability and good benefits forroot growth. And the diskless rice seedlingraising methodeffectively solves the problems of high cost and heavy investmentof disk seedling raising method, and is easy to operate, labor-saving, time-saving and capable of improving the utilization of rice seedling beds.
Description
Technical field [0001] The invention belongs to the technical field of rice planting, and specifically relates to a method for raising rice seedlings without a tray. Background technique [0002] With the transfer of rural labor, artificial rice seedlings can no longer meet the requirements of my country's social and economic development. The low production efficiency, low labor productivity, and high labor intensity of traditional rice farming techniques based on manual seedling transplanting restrict the development of rice production. In terms of production, there is an urgent need for labor-saving, labor-saving, high-yield and efficient modern rice production technology with mechanized operations as the core, especially rice transplanting technology. In recent years, with the support of policies, my country's rice transplanting technology has developed rapidly, and the proportion of mechanized rice planting rose from 4.4% in 2000 to 28% in 2012. However, the key to the succ...
