There are two main ways to control pests of Siraitia grosvenorii: physical pest control and chemical pest control. Physical pest control refers to the use of light or color to attract pests and diseases, and the use of light to kill insects. Chemical pest control refers to the use of pesticides, chemical fertilizers and other chemicals to eliminate pests, which may have a certain impact on the growth of Siraitia grosvenorii itself. In addition, it is best to focus on prevention and supplemented by treatment. Spraying some efficient and pollution-free pesticides in advance can greatly reduce the incidence of pests. 1、 How to prevent pests of Siraitia grosvenorii 1. Physical technology insecticidal: Siraitia grosvenorii is prone to diseases and pests in all stages of cultivation. The use of physical insecticidal technology can minimize the damage to them. Usually, light and color can be used to trap and kill insects. Science has proved that this way of killing insects is also very efficient.
2. Chemical Technology insecticidal: chemical insecticidal mainly refers to the use of chemical substances such as chemical fertilizers and pesticides. But this way is also the most harmful to the growth of Siraitia grosvenorii. High efficiency, low toxicity and residue free pesticides should be used as much as possible to reduce pesticide residues and heavy metal pollution and prevent affecting their normal growth. 2、 How to fertilize Siraitia grosvenorii 1. Apply base fertilizer: as a basic fertilizer, base fertilizer plays a vital role in the growth and development of Siraitia grosvenorii throughout the year. After the temperature warms up in March, some fully fermented base fertilizer can be applied, combined with deep tillage and land preparation, early application and deep application.
2. Topdressing: Siraitia grosvenorii has a high demand for trace elements such as nitrogen, phosphorus, potassium and magnesium. In the process of their growth, fertilizer and nutrients should be added in time. It is recommended to apply 4-6 kg of rotten pig and cow dung water and 0.2-0.3 kg of calcium magnesium phosphate (or calcium superphosphate) to each plant. During fertilization, mix the fertilizer with fine soil evenly, apply it in a ditch, and fill the soil to cover the fertilizer. (Luohan guozenmefangchong)
