The quality of soil directly determines the yield of prickly heat. If the soil quality is good and the living environment is good, manual maintenance will be much more convenient and the output will increase. The requirements for soil quality are not high, and it doesn't matter much if there is more sand, gravel, loess, clay and sand. Unique dishes are not afraid of cold, drought or waterlogging. The planting base requires a flat terrain and the land should be conducive to drainage. When the rainy season comes, there is too much water, so the rainwater should be drained as soon as possible, otherwise it is easy to die in a large area. The key point of the nursery must be conducive to the discharge of accumulated water, the soil quality is similar, and the sunshine time is enough.

Second, soil preparation

1. Cultivated land: Lepidium hybridum is very sensitive to fertilizer, and the soil is rich in fertilizer, which makes the growing plants oily green and healthy. However, the soil of a small part of the fields is nursery, and there are similar fertilizers. Because of this, in order to achieve high yield of the seeds of Lepidium chinense, it is necessary to apply enough green manure and sprinkle 4.5 ~ 6.5 tons of cow dung before planting. After applying fertilizer, plough the farmland 1 time and rake it 1 time, so that the soil and fertilizer are fully and evenly mixed together.

2. Border-making: In order to facilitate the necessary maintenance measures such as watering, weeding and fertilization during the whole growth period, it is suggested to make the land into a fixed border with a width of 1.4m and a total length of 16 ~ 22m, depending on the terrain.

Third, sow.

The seed size of Lepidium chinense is average, and the emergence rate is very good. Before planting, you can do some proper germination treatment. The method is actually very simple. Soak in cold water for 1 day, and then take out the dried lepidium seeds to make. The planting thickness should be shallow or shallow, and the covering soil thickness should not be more than 4 cm. Generally, seeds are sown one by one, and the conditions of calm wind are selected. Mix the seeds into the wet sand and then scatter them on the ground. After planting, it can be covered with artificial soil or mechanical soil. After covering soil, it can germinate after 1 irrigation, which takes about 6~ 12 days.

Fourth, maintenance

During the growth period, the amount of maintenance is less, there are basically no pests and diseases, and the growth state is vigorous. The most important thing is to water, pull weeds and prevent pests. At the peak of the growth of lone vegetable, a lot of water and fertilizer are needed. At this time, 35 kilograms of chemical fertilizer can be applied in 660㎡, and sufficient water is needed in the peak growth period of the lone vegetable. The frequency and time of watering should be decided according to the weather conditions.
