Problems solved by technology

[0005] China invented "Pineapple Controlled Release Fertilizer and Its Preparation Method". Application No. 201210580691.8 emphasizes the mass ratio of "nitrogen, phosphorus pentoxide and potassium oxide". It has no selectivity for varieties, and the target is not strong. There is no specific application amount and application During the period, pineapple yields were low; China invented "a comprehensive fertilization method for pineapple rhizosphere liquid fertilization", and the application number 201010198939.5 was aimed at the Bali variety and the pearl variety, not the thornless caine pineapple, which was different i

Abstract

The invention relates to a smooth cayenne pineapple package fertilizer and an application method thereof, and belongs to the technical field of agricultural production. The fertilizer application method comprises that the fertilizing amount per hectare comprising that when smooth cayenne pineapple is planted in August, a base fertilizer is applied with the amount of 895.9-939.5 kg, in February of a second year, a seedling strengthening fertilizer is applied with the amount of 918.8-972.9 kg, and in August of the second year, a bud promoting fertilizer is applied with the amount of 679.5-714.2 kg. The base fertilizer comprises the effective ingredients by the weight percentage: 19-20.5% of pure nitrogen, 69.5-71.0% of phosphorus pentoxide, and 29.5-31.5% of potassium oxide; the seedling strengthening fertilizer comprises the effective ingredients by the weight percentage: 49.0-51.0% of pure nitrogen, 29.0-31.5% of phosphorus pentoxide, and 28.5-30.5% of potassium oxide; the bud promoting fertilizer comprises the effective ingredients by the weight percentage: 29.0-30.5% of pure nitrogen, and 39.5-41.5% of potassium oxide. The application method can reduce application of nitrogen and phosphorus, reduces the risk of environmental pollution, besides, can improve the contents of soluble sugar and vitamin C of smooth cayenne pineapple, improves the yield of pineapple, and increases income.

Description

technical field [0001] The invention relates to a set fertilizer and its fertilization method, in particular to a thornless caine pineapple set fertilizer and its application method, belonging to the technical field of agricultural production. Background technique [0002] In recent years, my country has rapidly popularized set fertilizers and special fertilizers on food crops, effectively ensuring food supply, reducing the risk of environmental pollution, and promoting agricultural ecological security. However, for specific crops, especially tropical crops, there is a lack of in-depth and systematic research on package fertilizers and application methods. In addition, there are many types of tropical crops, and the fertilizers for specific economic crops can only be passively selected from products on the market. The applied fertilizers and crop nutrient requirements are different. Matching, resulting in a huge waste of fertilizers, causing potential pollution to the farmla...
