1、 Treated seeds

When planting, we should select the seeds without disease and bifurcation, first put them in the cellar for low-temperature treatment, take them out after two days, then put them in the sand to promote germination, and then transplant them when they grow young leaves

2、 Land preparation and planting

When planting, select the soil with good water retention and organic matter, mix and stir it with nutrient soil mixed with organic fertilizer, and then plant the germinated seedlings after finishing. When planting, the row spacing of plants should be between 15 and 20 cm, and should not be too close. After planting, cover it with a layer of soil and compact it. In addition, the seedlings should be seen in the later stage, and the seedlings that are too large and too small should be disposed of, so as to be more conducive to the growth of the main seedlings

3、 Fixed value management

When the seedlings grow to a height of about five centimeters, they should be weeded to avoid weeds competing for nutrients. When the length reaches ten centimeters, we have to weed again. In addition, it should be noted that excessive watering is not allowed at this time, and the soil is half wet. Pay attention to timely drainage in rainy season, and there must be no ponding. If it is a dry season, increase the amount of water

4、 Rational fertilization

If you want it to grow more vigorously, you should apply fertilizer reasonably in the later stage. Fertilizer is usually applied four times a year, the first two of which are carried out during seedling spacing. The fertilizer can be diluted fecal and urine fertilizer or urea fertilizer. It should also be applied when fixing seedlings, and the concentration should not be too high. In addition, plant ash shall be applied once in spring
