1. Base fertilizer: It is the material basis for ensuring good plant growth after planting. It requires large amount of fertilizer, full element, high concentration and proportion coordination. Use manure, compost, soil and fertilizer, waste fertilizer processed by tanning, green manure, and cake fertilizer. Add appropriate amount of chemical phosphorus, potassium and magnesium fertilizer.
Red soil and calcium red soil with low nitrogen and low calcium available phosphorus, 3.5-4 tons of fertilizer, 150-200 kilograms of superphosphate, 15-20 kilograms of potassium sulfate, 0.8-1 kilograms of magnesium sulfate, together with two topsoil Evenly, apply to the ditch and plant the seedlings.
2. Base fertilizer: The basic fertilizer for the growth and development of pineapple in one year is the material condition for ensuring high yield and high quality in the next year. Therefore, there is a theory of “one base wins and three chasingsâ€, which is applied after harvesting the second fruit. Shi Shi first opened the fertilization ditch between the foot or the row, put the dead leaves, fruit stems, weeds or green manure on the bottom of the ditch, and then applied the farmyard manure and fertilizer mixed with two topsoil. Generally, 2-2.5 tons of soil-fertilizer is applied per mu, 20-25 kg of NPK compound fertilizer, and 25-30 kg of cake fertilizer. Immediately after the application, the soil was cultivated.

3, topdressing:
1) Strong bud fertilizer. After the fruit is harvested, it is applied to the soil of the stem foot or the base of the petiole with Dole water to promote the growth of the bud.
2) Pre-flowering fertilizer. In the first month before flower bud differentiation, each plant applied 2-2.5 kg of fertilizer, 20-30 g of urea and 40-50 g of superphosphate to promote flower bud differentiation, increase the number of small flowers and enhance the cold resistance of the plants.
3) Promote bud fertilizer. In January, the stalk-based ditch was applied, mainly phosphorus and potassium fertilizers, mixed with half of the farmyard manure, and each plant was applied with 0.8-1 kg to promote the flower bud hypertrophy and lay a material foundation for increasing the fruit:
4) Strong fruit germination fertilizer. After the Xiehua and the small fruit expansion period from April to May, the application of potassium and phosphate fertilizers, combined with a small amount of nitrogen fertilizer, the amount of fertilizer used to account for 1/5 of the annual fertilization amount, ditching or using in the stem of the stem Dole is applied.

4, foliar spray fertilizer: Because the leaves of pineapple have special water storage structure and absorption function, the effect of foliar spray fertilizer is particularly good, especially when the fertilization of the rhizosphere is inconvenient after the plant is sealed, the foliar spray fertilizer is more fat An important way. In the vegetative growth period, nitrogen fertilizer is the main factor. In the reproductive growth period, potassium is the main factor, and phosphorus is the second. The foliar spray can be used to name the big fat treasure, Dole and calcium fertilizer. In May, June and July, each leaf surface is sprayed with Dole 1-2 times a month, which can significantly increase the sugar content and flavor of the fruit.
