A low-carbon integrated planting method of peat moss and rice rotation

Abstract

The present invention belongs to the field of rice cultivation and mainly relates to a rice cultivation method, specifically to a low-carbon integrated cultivation method using peat moss and rice rotation. The rice cultivation period in southern my country is generally divided into two planting seasons: spring and autumn, with spring lasting approximately from February to May and autumn lasting approximately from July to October. Therefore, rice fields have a certain fallow period each year. The present invention plants peat moss during the rice fallow period. The mosses increase the organic carbon content in the soil surface required for rice growth through photosynthesis, and regulate the soil pH, temperature and humidity conditions, and the number and activity of microorganisms. This can reduce the use of chemical fertilizers and pesticides, reduce environmental pollution, and reduce greenhouse gas emissions. It can effectively avoid soil fatigue, which is beneficial for improving rice yield and quality. The present invention can achieve efficient land utilization, increase crop yields, and reduce negative impacts on the environment, which is of great significance to the sustainable development of agriculture.

Description

Technical Field

[0001] The invention belongs to the field of rice planting, and mainly relates to a rice planting method, and specifically relates to a low-carbon integrated planting method of peat moss and rice rotation. Background Art

[0002] Rice is one of the world's most important food crops, but its cultivation presents several difficulties and challenges. Climate change can cause changes in climatic conditions such as temperature, rainfall, and drought in rice-growing areas, which can affect rice growth and yield. Furthermore, rice cultivation is often threatened by various pests and diseases, such as rice blast, rice leaf roller, rice planthopper, and rice straw borer, which can reduce yields or even kill rice. Ultimately, rice requires a suitable soil environment for normal growth. The quantity and quality of soil nutrients and microorganisms significantly influence rice growth and yield. However, the use of chemical fertilizers and pesticides in modern agricultural production can degrade soil quality and even cause land degradation, leading to a significant decline in rice yield and quality.

[0003] Sphagnum mosses are a special type of moss that typically grow in wetlands or marshes and possess unique ecological and geological significance. They belong to the phylum Bryophyta, primarily including the families Sphagnaceae and Polytrichaceae. Sphagnum mosses grow slowly, are large, and form fluffy mats. They possess excellent moisture retention properties, absorbing and storing large amounts of water, playing a crucial role in wetland ecosystems. They sequester large amounts of carbon and, under conditions of prolonged wetness, form thick peat layers. The organic matter stored in peat layers is primarily produced by the death and decomposition of peat mosses, making wetlands important carbon reservoirs. Furthermore, peat mosses provide habitat and food sources, playing a vital role in maintaining wetland biodiversity. Peat mosses have applications in agriculture, horticulture, and energy. Peat mosses can be used as fertilizers or soil conditioners, providing nutrients and improving soil structure.

[0004] Therefore, the present invention plans to rotate peat moss and rice to improve soil quality, reduce the use of pesticides and fertilizers, and increase rice yield and quality. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention provides a low-carbon integrated planting method of peat moss and rice rotation, which specifically includes the following steps:

[0006] S1. Preparation of bacterial solution: the concentration is 2.5×10 9 ~4.6×10 9cfu / ml of jelly-like Paenibacillus CICC21698 (purchased from Beijing Yuwei Technology Co., Ltd.) was prepared for use; the concentration was 1.5×10 9 ~3×10 9 cfu / ml of Bacillus megaterium ACCC11107 (purchased from Shanghai Xuanke Biotechnology Co., Ltd.) was prepared for use; the concentration was 2×10 9 ~3.8×10 9 cfu / ml of Bacillus subtilis subspecies NCTC 8236 (purchased from Beijing Biobowei Biotechnology Co., Ltd.) for later use; a bacterial solution of Paenibacillus jelly-like CICC 21698, a bacterial solution of Bacillus megaterium ACCC11107, and a bacterial solution of Bacillus subtilis subspecies NCTC 8236 were mixed in a mass ratio of 1:1:1 for later use; in this step, nitrogen-fixing bacteria can convert nitrogen in the air into ammoniacal nitrogen that can be absorbed by plants, thereby increasing the nitrogen content of the soil; Bacillus megaterium can convert organic phosphorus in the soil that is difficult for plants to absorb into soluble phosphorus, thereby increasing the content of available phosphorus in the soil; Clostridium tyrobutyricum can produce organic acids, which help to lower the pH value of the soil and increase soil fertility;

[0070] Rice yield measurement

[0071] Reference for rice yield determination method (Deng Shijun, Gu Yu. Effects of different nitrogen, phosphorus and potassium fertilizer dosages on rice yield and fertilizer utilization efficiency [J]. Shanghai Agricultural Science and Technology, 2022(03):98-100.); the results are as follows Figure 3 shown.

[0072] Figure 3 This is a comparison chart of rice yields for Examples 5 and 6 of Example 3. According to the results, using peat moss for crop rotation can significantly increase rice yield. When peat moss is not used for crop rotation, the yield of applying bacterial fertilizer to the soil during the fallow period cannot achieve the effect of using peat moss for crop rotation. Peat moss can improve soil texture and increase soil organic matter content during growth. At the same time, peat moss has the ability to absorb carbon dioxide. By planting peat moss, a large amount of carbon can be fixed in the soil, increasing the organic carbon level in the soil and thus high rice yield.

Preparation of bacterial solution: the concentration is 2.5×10 9 ~4.6×10 9 cfu / ml of jelly-like Paenibacillus CICC21698 bacterial solution is ready for use; the concentration is 1.5×10 9 ~3×10 9 cfu / ml of Bacillus megaterium ACCC11107 bacterial solution was prepared at a concentration of 2×10 9 ~3.8×10 9 cfu / ml of Bacillus subtilis subspecies NCTC 8236 bacterial solution for use; jelly-like Paenibacillus CICC 21698 bacterial solution, Bacillus megaterium ACCC11107 bacterial solution and Bacillus subtilis subspecies NCTC8236 bacterial solution were mixed in a volume ratio of 1:1:1 for use; S2. Rice Variety Selection: Select high-quality, high-yield varieties with strong lodging resistance, good stress tolerance, wide adaptability, and strong disease and pest resistance. Ensure that the harvest period is before early November, the seed quality and germination rate meet GB / T 3543.4-1995, and the full growth period is 125-135 days. S3. Site selection: Choose an area with a guaranteed water source, convenient drainage, good isolation conditions, and flat terrain as a planting base. After the previous round of rice harvest, all weeds and straw in the rice fields must be thoroughly removed. S4. Pretreatment of rice seeds:

1. Cleaning: Pretreat the rice seeds by soaking them in clean water and gently rubbing them to remove impurities, nodules and chaff on the surface; 2. Seed soaking: Soak the rice seeds in warm water at 30°C for 6-8 hours or in cold water at 20°C for 12-24 hours to allow the seeds to fully absorb water and promote embryo development; 3. Salting: Soak the rice seeds in salt water with a salt concentration of 20%, rinse them with clean water after 50-60 minutes, which can prevent the seeds from mold and rot and reduce insect pests; 4. Heat treatment: Put the rice seeds in a pot of boiling water, boil for 5-10 minutes, take them out and dry them, which can effectively kill the bacteria and insect eggs on the surface of the seeds; 5. Germination: Add the rice seeds to an appropriate amount of boiling water, and when the water temperature drops to 38-40°C, take them out, place them on a damp towel, cover them with plastic wrap and place them in a place with suitable temperature to promote seed germination; S5. Rice planting: Sow the pre-treated seeds in mid-April every year, choose a seedling raising site with loose soil and good drainage, and carry out leveling and ploughing work. The rice sowing density is 6-8 kg per mu, and transplant the rice seedlings in early May. When transplanting, ensure that the roots of the rice seedlings are not damaged, avoid broken roots and broken roots, and the depth of transplanting should be moderate, burying the roots of the seedlings 5-7 cm in the soil. The density of transplanting should be appropriate, 60,000 to 80,000 plants per mu. After transplanting, irrigate in time to make full contact between the soil and the roots of the seedlings, and maintain appropriate moisture conditions. Avoid overheating or overcooling, overdrying or overhumid environments when growing rice, ensure sufficient sunlight to promote photosynthesis and growth and development of the seedlings, control the water level in the field, and maintain appropriate moisture conditions, but not Do not over-flood, harvest in late July, and then immediately transplant late rice, end before the beginning of autumn, and harvest late rice in late October-November; apply bacterial fertilizer during the growth of rice, apply base fertilizer, dilute the mixed bacterial solution prepared in step S1 with water 100-300 times, and irrigate the roots at 2-3 kg / mu; apply tillering fertilizer, dilute the mixed bacterial solution prepared in step S1 with water 200-500 times, and irrigate the roots at 1-2 kg / mu; apply panicle fertilizer, dilute the mixed bacterial solution prepared in step S1 with water 200-500 times, and irrigate the roots at 1-2 kg / mu; apply granular fertilizer, dilute the mixed bacterial solution prepared in step S1 with water 200-500 times, and irrigate the roots at 1-2 kg / mu; S6. Planting of peat moss: Peat moss is planted during the fallow period from February to May every year. The peat moss will be cultivated in the laboratory at a temperature of 22-23℃, a light intensity of 1500-3000Lx, a light-dark cycle of 16 h / 8 h, and a humidity of 80-90%. It will be planted at a density of 0.5-1 plants per square centimeter. For smaller seeds, you can mix them with a small amount of dry sand for easy even sowing. Sprinkle the seeds evenly on the surface of the substrate, lightly cover with a layer of substrate, spray with an appropriate amount of water, keep the substrate moist, but do not over-soak it, spray water regularly to keep the substrate moist, but do not over-water to avoid waterlogging and root rot.
