Heart-nourishing vegetables, also known as heart-saving vegetables, high-calcium vegetables or health-care high-calcium vegetables, are 30-70 cm high, with many stems and leaves, 4 cm long and 3 cm wide, alternating layers. The improved third generation vegetables have high medicinal value. Planting time: Yangxin vegetable is a perennial succulent herb, and the planting time is generally in spring and autumn. The climate in the north and south is different, so the planting time is somewhat different. The planting time in the south is mostly from mid-late March to early April, mid-late May and mid-late September, and the climate in the north is slowly warming up. Planting time can be selected from April to early May, or from the middle and late September to 10. Soil selection: Vegetables rich in nutrients are suitable for planting in flat places, not in low-lying places, but in sandy loam with high organic matter content. Dig the soil deeply and rake it carefully, and apply decomposed fertilizer to ensure a suitable planting environment. Accelerating germination and sowing: When accelerating germination of Chinese cabbage seeds, the seeds should be soaked in warm water for half an hour, and then poured into hot water at 60-70℃. They need to be constantly stirred during dumping. After the seeds absorb water, they need to be wrapped with wet cloth, and then placed in an environment of 25-35℃ to accelerate germination. After the seeds turn white, they can be planted. Fertilizer and water management: after planting, topdressing should be applied less. Generally, topdressing is 65,438+0 times a month or watering is coordinated, and 65,438+00 kilograms of urea and 3 kilograms of potassium dihydrogen phosphate are applied per mu. Before wintering or turning green, 2000 kg of decomposed manure or 50 kg of ternary compound fertilizer should be applied per mu. 1 After harvest, potassium chloride10kg or plant ash100kg should be applied to each mu in time to promote branching and increase yield. If the soil is dry, water it in time and water it thoroughly. Nourishing vegetables should avoid waterlogging, and ditches should be cleaned and drained in time in rainy season.
