[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 in variety; Special foliar fertilizer for pineapple and its application method”, the application number 200910093675.4 is aimed at the Bali variety, and the application for protection of the “external root fertilization method and application amount” is sprayed on the pineapple leaves when used, mainly absorbed by the stomata of the leaves. Topdressing fertilizer application, while base application at the root, is suitable for ordinary furrow application and drip irrigation fertilization, and the application method of the special fertilizer for thornless caine pineapple based on the root system has not been reported yet.

Abstract

The invention relates to a thornless caine pineapple set fertilizer and an application method, belonging to the technical field of agricultural production; the fertilizer application amount per hectare of the fertilization method of the invention is as follows: when planting in August, 895.9-939.5 kg of base fertilizer is applied, and 2 in the second year. 918.8~972.9kg of seedling-strengthening fertilizer is applied in the month, and 679.5~714.2kg of bud-promoting fertilizer is applied in August of the second year; the active ingredients of the base fertilizer are composed by weight percentage: pure nitrogen 19~20.5%, phosphorus pentoxide 69.5~71.0% %, potassium oxide 29.5~31.5%; the active ingredient of described seedling strengthening fertilizer is composed by weight percentage: pure nitrogen 49.0~51.0%, phosphorus pentoxide 29.0~31.5%, potassium oxide 28.5~30.5%; The active ingredients of the fertilizer are composed by weight percentage: pure nitrogen 29.0~30.5%, potassium oxide 39.5~41.5%; this application method can reduce the application of nitrogen and phosphorus, reduce the risk of environmental pollution, and at the same time can improve the thornless caine pineapple. The content of soluble sugar and vitamin C, increases the yield of pineapple and increases the yield.

Description

technical field [0001] The invention relates to a fertilization method for a set fertilizer, in particular to a method for applying a thornless caine pineapple set fertilizer, and belongs 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 the application methods of package fertilizers. 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 farmland...
