Problems solved by technology

[0002] There are two kinds of the latest rice seedling raising technology. One is the two-stage rice seedling raising technology in the northern cold region, which is reported in the 9th issue of "Agricultural Science and Technology News" in 2012 and the 17th issue of "Agriculture and Forestry Science and Technology" in 2011. That is, the first stage is to raise seedlings in greenhouses , the second section is transferred to the field and transplanted in two times. This technology is time-consuming and labor-intensive, and the seedlings occupy a large area; The cost of building a shed is high and the lighting is uneven

Embodiment 1

[0027] First, mix peat, leftovers of cultivated edible fungi (such as saw foam), animal manure (such as pig manure or sheep manure or a mixture of the two) and mellow soil in a mass ratio of 1:1:1:1, and use Stack retting to achieve full maturity to make light seedling soil, spread the light seedling soil into the seedling tray, and sow the broken seeds into the light seedling soil through a seeder, and then place the seedling tray to the seedling rack;

[0028] Place the seedling raising frame in the vertical seedling greenhouse for darkening and heating, and control the temperature of the vertical seedling greenhouse through the electric boiler for temperature increase, the sensor for temperature control and the humidifier for humidity adjustment in the vertical seedling greenhouse. The ambient temperature is kept at 30°C, the humidity is kept at 90%, and the temperature and humidity of the bottom layer and the top layer of the three-dimensional seedling greenhouse are adjus...

Embodiment 2

[0031] First, mix peat, leftovers of cultivated edible fungi (such as saw foam), animal manure (such as pig manure or sheep manure or a mixture of the two) and mellow soil in a mass ratio of 1:1:1:1, and use Stack retting to achieve full maturity to make light seedling soil, spread the light seedling soil into the seedling tray, and sow the broken seeds into the light seedling soil through a seeder, and then place the seedling tray to the seedling rack;

[0032] Place the seedling raising frame in the vertical seedling greenhouse for darkening and heating, and control the temperature of the vertical seedling greenhouse through the electric boiler for temperature increase, the sensor for temperature control and the humidifier for humidity adjustment in the vertical seedling greenhouse. The ambient temperature is kept at 35°C, the humidity is kept at 94%, and the temperature and humidity of the bottom layer and the top layer of the three-dimensional seedling greenhouse are adjus...

Embodiment 3

[0035] First, mix peat, leftovers of cultivated edible fungi (such as saw foam), animal manure (such as pig manure or sheep manure or a mixture of the two) and mellow soil in a mass ratio of 1:1:1:1, and use Stack retting to achieve full maturity to make light seedling soil, spread the light seedling soil into the seedling tray, and sow the broken seeds into the light seedling soil through a seeder, and then place the seedling tray to the seedling rack;

[0036] Place the seedling raising frame in the vertical seedling greenhouse for darkening and heating, and control the temperature of the vertical seedling greenhouse through the electric boiler for temperature increase, the sensor for temperature control and the humidifier for humidity adjustment in the vertical seedling greenhouse. The ambient temperature is maintained at 33°C, the humidity is maintained at 96%, and the temperature and humidity of the bottom and top layers of the three-dimensional seedling greenhouse are ad...

Abstract

The invention discloses a three-dimensional sectional seedling cultivating method of rice in cold regions. The three-dimensional sectional seedling cultivating method includes firstly laying light seedling soil into seedling trays, sowing seeds in the light seedling soil, and arranging the seedling trays on a seedling cultivating frame; placing the seedling cultivating frame in a three-dimensional seedling cultivating greenhouse and controlling the environment temperature within 30-35 DEG C and humidity over 90% in the greenhouse; planting the seedlings in the seedling cultivating frame into a seedling cultivating greenhouse after the seedlings grow with one leaf and one bud in the greenhouse. By the three-dimensional sectional seedling cultivating method of the rice in the cold regions, field space for seedling cultivation is saved, effective accumulative temperature is increased, rice growth period is prolonged and yield increasing potential of medium and late varieties is developed.

Description

technical field [0001] The invention relates to the technical field of rice seedling raising in cold regions, in particular to a three-dimensional segmented rice seedling raising method in cold regions and a vertical rice seedling stand for cold regions. Background technique [0002] There are two kinds of the latest rice seedling raising technology. One is the two-stage rice seedling raising technology in the northern cold region, which is reported in the 9th issue of "Agricultural Science and Technology News" in 2012 and the 17th issue of "Agriculture and Forestry Science and Technology" in 2011. That is, the first stage is to raise seedlings in greenhouses , the second section is transferred to the field and transplanted in two times. This technology is time-consuming and labor-intensive, and the seedlings occupy a large area; The cost of building a shed is high and the lighting is uneven. The present invention not only has the advantages of the above two technologies, b...
