The field management of stevia: after stevia is planted, you should grasp the five links of seedling replenishment, irrigation, fertilizer and topping and centering. After planting seedlings, 5-7 days should start to check the field to make up seedlings, to ensure that the whole seedling, to improve the yield. Stevia is resistant to moisture and afraid of drying out, high temperature and lack of rain in summer, when there is insufficient water, the lower leaves are easy to wither and fall off, especially during the seedling planting and slowing down of the most sensitive to the water, so after planting, every 2-3 days depending on the soil humidity for irrigation, it is desirable to small water irrigation, so that the soil water holding capacity of 60% or so, which is the key to the full seedling yield.

Stevia is a fertilizer-resistant crop, its medicinal part is the leaves, only enough fertilizer to make the plant grow tall, tillers, leaves and fat, good quality, high yield, therefore, in addition to applying enough fertilizer to supply the entire growth, but also need to be fertilized in order to meet the needs of the various stages of its growth and development. Stevia seedlings grow more slowly, in order to accelerate growth, so after the seedling should be combined with irrigation per mu of ammonium sulfate 6 kg, or 800 kg of rotted human urine. In the early stage of vigorous growth, 15 kg of urea per mu should be applied. Later every 20-30 days as needed for foliar spraying of potassium dihydrogen phosphate 2-3 times, the dosage of about 2 kg per mu. In order to promote stem and leaf proliferation to increase production, when the seedling height of 20 to 25 cm, in addition to seed retention, can be topped, centering, topping and centering, to promote the growth of lateral branches, each plant than the control group can be added to the branching 12, can increase yields by more than 30%.
