The pest control of pitaya fruit can be carried out through scientific control and land cleaning. The specific implementation measures of scientific prevention and control include beating pesticides and cutting off diseased branches. At the same time of applying pesticides, applying fertilizer, cleaning weeds and pruning diseased branches can not only avoid the large-area reproduction of pests, but also promote plant growth. Land cleaning refers to cleaning at ordinary times to avoid negligence due to small pests. In winter, clear the garden, dig the soil deeply and destroy the winter place of pests. 1、 How to prevent insects from pitaya 1. Scientific prevention and control: applying pesticides is not only an important means to reduce the incidence of diseases and pests, but also the primary item in scientific prevention and control. The time of pesticide application shall be before the large-scale reproduction of pests, and the principle of pesticide application at the sight of pests shall be followed. However, when using chemicals, we must not be careless. We must spray pesticides on all hidden places.
2. Land cleaning: before planting pitaya, be sure to clean up the weeds, dead branches and leaves and some garbage in the ground. Keeping the land clean can spread pests in a large area and affect the planting of plants in the future. 2、 How to plant pitaya 1. Planting time: pitaya is a thermophilic species and tropical food, which has certain requirements for the temperature of the climate. The best planting time is March and April every year. Pitaya likes direct sunlight. The longer the illumination time, the stronger the photosynthesis, the more flowers and the greater the results.
2. Topdressing fertilizer: pitaya grows very fast, and fertilizer is very important in the growth cycle. Applying different fertilizers in different periods can help it grow faster. Generally, nitrogen fertilizer can be used more in the early stage of planting to ensure the growth of rhizomes. The use of nitrogen, phosphorus and potassium fertilizer in the middle and late stage can increase the photosynthesis of plants and promote the formation of fruits. （HuoLongGuoZenMeFangChong）
