Embodiment 1

[0025] Cultivation of green feed corn in solar greenhouse. The germination stage and seedling stage are cultivated in the solar greenhouse used in the seedling room, and the newly germinated corn seeds are planted in the seedling pot. After 20-25 days, when the seedling grows to 10-30cm, the pot soil is transplanted to the growing pot. In the greenhouse, 5,000 to 8,000 green feed corns are planted per mu. Use biogas residue as base fertilizer, and biogas slurry and biogas residue as top dressing. 2,500-6,000kg of biogas residue base fertilizer per mu, 1,000-1,500kg of biogas residue topdressing fertilizer, biogas slurry topdressing depends on the growth of green corn, and is generally irrigated or sprayed in a timely manner during the jointing stage, pollination stage, and grouting and milking stage. Daytime CO 2 The concentration is controlled at 800~1200ppm / cm 3 , less than 800ppm / m 3 When opening the valve to supplement CO 2 , higher than 1200ppm / m 3 When the valve is...

Embodiment 2

[0027] Cultivation of sweet sorghum in solar greenhouse. The germination stage and seedling stage are cultivated in the solar greenhouse for seedling room. After the seedlings grow in the seedling shed for 10 to 20 days, when the seedling height is 10 to 30 cm, they are transplanted into the solar greenhouse for growth with potting soil for cultivation. Planting 4000 per mu ~7500 plants. Use biogas residue as base fertilizer, and biogas slurry and biogas residue as top dressing. 2,500-6,500kg of biogas residue base fertilizer per mu, 1,000-1,500kg of biogas residue topdressing, and biogas slurry topdressing depend on the growth of sweet sorghum, and are generally irrigated or sprayed in a timely manner during the jointing stage, pollination stage, and grouting and milking stage. Daytime CO 2 The gas concentration is controlled at 900~1150ppm / cm 3 , less than 900ppm / m 3 When opening the valve to supplement CO 2 , higher than 1150ppm / m 3 When the valve is closed, the natur...

Embodiment 3

[0029] Sorghum grass is cultivated in the solar greenhouse. Cultivate in the seedling shed during the germination and seedling stages, plant the newly germinated Sorghum grass seeds in the seedling pots, and after 20-25 days, when the seedlings grow to 10-30cm, transplant them into the solar greenhouse for growth with potting soil middle. Grow in a solar greenhouse for 140-160 days. During the period, the plant can be cut once when the plant grows to 1.3-1.6m. After cutting, new shoots will grow from the roots to grow into new seedlings. During the growth period, it can be cut three times. Plant 5,500 to 8,300 Sorghum per mu. Apply 3,500-6,000 kg of organic base fertilizer, and 1,000-1,500 kg of topdressing fertilizer. Topdressing should be applied after each cut, and topdressing should be done at the jointing stage. 日间CO 2 Gas concentration can be controlled at 900~1200ppm / cm 3 ,低于900ppm / m 3 时打开阀门补充CO 2 , higher than 1200ppm / m 3 When the valve is closed, the natural con...

Abstract

The present invention relates to a method for planting forage grass by utilizing heliogreenhouse. It is characterized by that said method includes the following steps: close-planting and cultivating the germinated seeds in seedling room, controlling CO2 concentration and making it be 800-1200 ppm / cu.m, making cultivation at 10-40deg.C to obtain forage grass seedlings; transplanting the forage grass seedlings into a heliogreenhouse for promoting growth of forage grass, controlling CO2 concentration and making it be 800-1200 ppm / cu.m, after the forage grass seedlings are grown for 70-160 days at 10-40deg.C, harvesting forage grass. Several heliogreenhouses for promoting growth of forage grass can be combined together so as to form a forage grass production system.

Description

technical field [0001] The invention relates to a method for planting forage grass, in particular to a method for planting forage grass in a solar greenhouse. The present invention recovers CO from industrial production 2 Supplement forage grass in the greenhouse, and use the photosynthesis of forage grass to absorb CO 2 , to fix carbon in the forage grass to increase green forage production and reduce CO emissions 2 double effect. Background technique [0002] In the past two decades, my country's animal husbandry has developed rapidly, and it is moving from a large animal husbandry country to a strong animal husbandry country. The bottleneck in the development of animal husbandry is to solve the forage problem. my country's animal husbandry industry uses nearly 100 million tons less feed grain than the United States every year, but produces 20 million tons more meat. The main reason for this is the large use of green fodder. At the same time, a large amount of green f...
