The planting methods of Pseudomonas aeruginosa include soil preparation, sowing, planting, watering and fertilizing. Sow seeds in spring from February to April, autumn varieties in late July, and winter and spring varieties in late September to early October.

1. Land preparation for sowing

The soil required for planting Xuelihong requires high fertility. Before planting, the land should be leveled into strips and a foot-wide drainage ditch. When sowing, generally choose to sow in the morning or evening after rain. The amount of seed per mu is about 1 catties. Before sowing, pour enough water and cover with light soil after sowing. After the seedlings emerge, strive to ensure that the seedlings are uniform, even and strong.

2. Planting

In the snow, the red seedlings are about 15 cm tall and have 5 leaves. Depending on the weather conditions, transplant the seedlings in the snow. The time should be controlled at around 8 to 10 o'clock in the morning. There should be a certain amount of soil on the seedlings. When planting, the row spacing is required to be 30 cm, the plant spacing is 35 cm, and about 4,000 plants per acre are required. Watering must be done after transplanting.

3. Watering

After transplanting Xuelihong, prevent drought and waterlogging. If it doesn't rain often, watering should be done in time. If watering is not carried out in time, the red in the snow may dry out. If it is rainy season, drainage work should be done well. Although Xuelihong prefers water, if it is watered frequently, water may accumulate in the ground, which will greatly affect the growth of Xuelihong.

4. Fertilization

The fertilizer for Xuelihong is mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer. Usually, one acre of land requires 100 kilograms of compound fertilizer, 100 kilograms of ammonium carbonate, 30 kilograms of calcium, magnesium and phosphate fertilizers, and 20 kilograms of potassium chloride fertilizer. It is worth noting that watering and top dressing should not be carried out 20 days before we pick Xuelihong, which can effectively improve the quality of Xuelihong.

Planting time

The planting time of potherb mustard is determined according to the variety and consumption method. It is generally divided into three sowing periods. Sow seeds in spring from February to April, and sow autumn varieties around late July. Winter-spring varieties are usually sown from late September to early October and transplanted 30 days later. The above-ground parts, tender shoots, stems and leaves are harvested during the spring bolting period. You can pickle vegetables.
