1. Land selection and preparation: sandy neutral loam is the first choice. On the selected plot, spread 4000 kg of decomposed manure and 50 kg of compound fertilizer per mu, plow and rake to make a ridge with a width of 2 meters, with a ridge in the middle and a width of 30 cm ×30 cm.

2. Seedling raising: High-calcium vegetables have strong stress resistance and strong vitality, and it is easier to carry out cutting seedling raising and cultivation management. Seed propagation can also be used, but cuttage is generally used to raise seedlings, which can be carried out in greenhouse in spring, summer, early autumn and winter.

3. Fertilizer and water management: Plantar fertilizer should be applied before planting, but less after planting. Generally, manure or chemical fertilizer is applied once a month to mix water, and 5 kg of urea and 3 kg of potassium dihydrogen phosphate are applied per mu. Lysimachia christinae should be watered according to the principle of "seeing dry and seeing wet", that is, if it is not dry, it must be watered thoroughly. Pay attention to trenching and drainage in rainy season.

4. Intertillage weeding: Intertillage weeding should be carried out several times a year, and weeding at seedling stage needs weeding. Before wintering every year, before turning green in early spring and after mowing every time, we should concentrate on loosening the soil and weeding.

5. Pest control: There are few pests and diseases in high-calcium vegetables. If there are pests, pyrethroids or biological pesticides can be used as appropriate. Such as using Sophora flavescens insecticide to control root maggots; Control aphids with tobacco stem water and Chinese herbal medicine aphid mites.
