Embodiment 1

[0042] Specific steps are as follows:

[0043] 1. Rapid reproduction

[0044] (1) Seedbed preparation

[0045]Most grass sorghum, false sorghum, sudangrass and other hybrid varieties of sorghum have small seeds and weak ability to top the soil. Large fields require intensive cultivation and level ground. Combined with plowing, apply 1000-1500kg of organic fertilizer, 50-100kg of superphosphate, and 50kg of nitrogen fertilizer per mu, or apply 1000-1500kg of organic fertilizer and 50-75kg of compound fertilizer per mu. The plowing depth is 20-25cm, and the topsoil is finely raked.

[0046] (2) Seed treatment

[0047] From April to June, when the soil temperature reaches above 10°C, start sowing. Early sowing on sandy soil and dry land, late sowing on clay and depressions. 7-15 days before sowing, dry the seeds for 1-2 days; 2-3 days before sowing, soak the seeds in warm water at 45-60°C for 0.5-1 hour, pile them up in a place with a temperature of 20-30°C, and cover them w...

Abstract

The invention discloses a method for fast growth, high yield and high-efficient carbon capture cultivation of grain sorghum and sudan grass. The method comprises the following steps of using the grain sorghum, sorghum halepense, sudan grass and sorghum moench hybrid seeds for propagation; enlarging the planting area; and by fast propagation, high-yield cultivation, multi-time harvest and timely landfill technologies, cradling for 4-6 times a year, and enabling the yield to reach 90-200T / hm<2>. By using the sorghum plant photosynthesis, the CO2 in the atmosphere can be converted into organic compounds to be filled under the ground, therefore, the negative growth in global carbon emission can be achieved, and the atmospheric greenhouse effect can be reduced; the Earth's ice melt can be choked, the sea-level rise can be controlled, the Earth's climate and biodiversity the maintained, and the life time of the humans on the Earth can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a fast-growing, high-yield and high-efficiency carbon-capturing cultivation method for sorghum and sudan grass. Background technique [0002] Sorghum (Sorghum bicolor (L.) Moench) is an annual herb of the Poaceae Sorghum genus. According to the purpose, there are sorghum for grain, sugar and grass. Grass sorghum generally uses medium and late-maturing large sorghum, represented by sweet sorghum. High yield, strong stress resistance, plant height 2-3 meters, can be mowed 2-4 times a year, fresh grass yield 5-12 tons per mu. Sorghum halepense (Linn.) Pers, also known as Sorghum halepense (Linn.) Pers, belongs to the Gramineae Sorghum genus, perennial tropical and subtropical planting, and temperate one year. Shimao likes sunlight and is resistant to high temperature. It can grow in soil with a pH of 4.8 to 7. It grows best on fertile and loose soil, and its height can re...
