The seed is very small, so it is necessary to finely prepare the soil before sowing. Apply appropriate amount of manure and phosphate fertilizer as base fertilizer in poor soil to facilitate nodule formation. Appropriate amount of lime should be applied to the acid soil, and 20 to 40 kg of lime per mu when the soil pH is 5-6. Inoculated with rhizobium nodularium when cultivated on soil that has never been planted has good yield-increasing effects. It can be broadcast in spring, summer broadcast, autumn broadcast or winter broadcast. Spring sowing is good, and areas where wind and sand are less harmful can be sowed in spring. In the spring drought, late frosts occur later, and areas with more sandstorms can be sown during the rainy season. It is not too cold in winter, and it can be broadcast in autumn in areas with a plant height of up to 10–15 cm before winter. Autumn sowing is good, and weeds are less harmful. Can also be sowed in the early winter soil before the beginning of freezing, the year does not make germinate, until the second year of early spring using soil defrosted water to emerge. Seedlings of plants are short and vulnerable to weeds. Weeding should be done in time. The large amount of water consumed by thorium consumes 800 pounds of water per kilogram of dried matter. Therefore, during the dry season, irrigation can greatly increase the amount of grass production. Pre-winter froze the water to help the plants overwinter. Early spring irrigation and irrigation after each castration are very significant in improving the yield of alfalfa. In the early spring before returning to green land after squatting or cutting, cultivating tillage is beneficial to improve soil aeration and preserve soil moisture, and promote the growth of earthworms. Should be cast at the early flowering stage, affecting the yield too early, and reducing the feed value too late. It is advisable to keep a height of 5 cm for regeneration. The last harvest should not be too late. It should generally be carried out before September 25th so that the regenerated grass before winter can grow to 10–15 cm in order to accumulate nutrients for safe wintering and the following year. One year can be castrated 3 - 4 times, the general yield of grass 5000 - 6000 pounds, high-yield up to 10,000 pounds or more. Every 4 - 5 kg of fresh grass can be dried 1 kg of hay. Seed farming should be diluted seeding, seeding amount of 1 kg is appropriate, spacing 40-50 cm. It is not appropriate to sow in the year of sowing, and the first barnyardgrass is used to harvest seeds after the second year.
