The planting method of Rabdosia angustifolia

First of all, the varieties should be selected, such as dwarf resistant green, winter evergreen and Shanghai green varieties. 1000 kilograms of mature farm manure was applied per mu as base fertilizer. Sow the seeds evenly on the border surface, rake the border surface after sowing, cover the seeds, and pour enough water. Do a good job of field management.

1. Variety selection

The selection of varieties is also different in different seasons. when planting in spring, we should choose varieties with strong cold resistance, such as slow February and winter evergreen, etc., while the temperature in summer is very high, so we should choose varieties with strong heat resistance, such as heat-resistant 605 and summer holly, etc.; the temperature is suitable in the early stage of autumn and winter planting, and the temperature is lower in the later stage, generally choose short resistant evergreen, winter evergreen and Shanghai green varieties.

two。 Soil preparation and fertilization

The growth cycle of Rabdosia angustifolia is very short, so a week before ploughing, 1000 kilograms of rotten farm manure should be applied per mu as basic fertilizer, and it should be buried in the soil by ploughing, leveling and raking fine, and then making beds, and planting in the greenhouse in spring, so shallow beds are generally made; while summer is a high-temperature and rainy economy, it is necessary to make deep ditches and high beds, which are conducive to irrigation and drainage; autumn and winter are higher than spring, but shorter than summer.

3. Sowing seeds

When sowing, sow the seeds evenly on the border surface, rake the border surface after sowing, cover the seeds, then step on them, and water them according to the dry moisture of the soil, generally sowing 2 kilograms per mu. Summer is in the high temperature season when sowing, so at the stage of sowing to seedling emergence, shading measures should be taken to avoid strong light from directly drying the seedlings, and the weather is dry, and it is necessary to water once before sowing and sow after the water seeps into the soil. Before emergence, it is necessary to keep the soil moist at all times, high temperature in summer and low survival rate, so the sowing amount is also large, generally sowing 2-4 kg per mu. Autumn sowing is also a period of high temperature, when sowing, if the soil is too dry, it should be watered first, and the sowing method and amount are the same as in spring.

4. Field management

The planting of Rabdosia angustifolia is relatively simple. in the case of sufficient base fertilizer, it can be harvested only after topdressing twice. After the first topdressing of cotyledon, 5 kg of urea per mu is recommended to be washed with water, and 10 kg of urea is applied per mu after the emergence of two true leaves. At the same time, the soil should be kept moist and watered frequently, but it should not be watered with heavy water. at the same time, attention should be paid to the invasion of diseases and insect pests, which are mainly virus diseases, such as aphids, cabbage insects, cabbage moths, and so on. It can be harvested after sowing in spring for 40-50 days, 20-25 days in summer and 25-40 days in autumn and winter.
