1, accelerating germination
Before planting green vegetables, it is best to accelerate the germination of seeds. First, spread the seeds evenly on the sand, cover them with a thin layer of soil, and after watering once, it is best to keep the soil moist. Put it in a warm and humid environment, spray water 1 ~ 2 times a day to strengthen air circulation, and germinate after about 3 ~ 4 weeks.
2. Soil-prepared vegetables are one of the main vegetables planted by vegetable farmers, and how to plant them is more reasonable. First, a proper amount of compound fertilizer solution is added to the soil as base fertilizer, then the soil is loosened and fully stirred evenly, and a small drainage ditch is made around the soil to facilitate drainage in rainy days.
Step 3: sow.
Place the germinated seedlings flat on the culture soil, keeping the part with the bud tip facing down at a distance of about 15 ~ 20 cm, gently press around with a thin layer of soil, add water in time, and then add the decomposed organic fertilizer solution. It is best to apply urea solution after the plants survive.
4, water and fertilizer seedlings should always keep the soil moist after planting, drainage treatment should be carried out in rainy season, watering should be done once a day in hot climate, remember not to be too much, urea solution should be applied every 2 ~ 3 weeks during the growth period, and the reduction times in autumn and winter are the best, and each fertilization should be combined with watering.
5. illness
Black spot disease and white spot disease are common diseases in the growth of green vegetables, which are very harmful. They mainly erode the leaves and stems of plants, and the leaves will grow poorly, turn yellow and curl. It is best to strengthen air circulation frequently. If diseases are found, chlorpheniramine solution can be sprayed.
