Last Updated: 2024/11/05, Because root nematode parasitism in the root, and make root tissue excessive growth, the formation of different sizes of tumors. Control methods: quarantine, can not carry nematodes with the plant, to no disease area. When opening up new orchards, plowing and drying the soil in sunny weather can also kill root nematodes by sunlight.

The high yield of growing pineapple needs a whole set of scientific fertilization technology to guarantee. Among them, the key technologies of base fertilizer and topdressing are the most important. The ratio of nitrogen, phosphorus and potassium in the vegetative growth period is 17:10:16 and the flowering stage is 7:10:23. Therefore, attention should be paid to the supply of nitrogen and potassium in pineapple fertilization. the application of sufficient basal fertilizer will lay a good foundation for high yield. According to the southern climate and the fertilizer demand characteristics of pineapple, the scientific fertilization measures are suggested as follows: base fertilizer: the one-time application of sufficient base fertilizer in the dry and barren soil of pineapple is the basic measure for high yield and quality of pineapple. It is suggested to use high tower sulfur fertilizer 15-15-15 or 17-17-17. Topdressing: topdressing with high tower sulfur base fertilizer 15-15-15, 17-17-17 or nitro-sulfur fertilizer 21-6-13 at seedling stage. The application of nitro fertilizer 15-5-20, sulfur-based fertilizer 18-5-25 and 16-6-24s had a good effect on fruit expansion and fruit quality. Farmers can adjust the specific use of fertilizer according to local varieties and fertilization habits. Welcome to consult local agricultural technicians.
