Abstract

The invention provides a special fertilizer for drip irrigation of asparagus and preparation and fertilization methods of the fertilizer. The special fertilizer for the drip irrigation of the asparagus is composed of a special fertilizer for the harvest period, a special fertilizer for the growing period of mother stalks and a special fertilizer for the nutrient accumulation period, wherein the special fertilizer for the harvest period comprises the following components in parts by weight: 380-396 parts of potassium nitrate, 165-182 parts of monoammonium phosphate, 420-440 parts of urea, 2-3 parts of EDTA chelated calcium, 1-2 parts of EDTA chelated ferrous, 0.03-0.05 part of sodium molybdate, 1-2 parts of EDTA chelated manganese, 0.5-1 part of EDTA chelated zinc, 0.1-0.3 part of EDTA chelated copper and 1-1.5 parts of boric acid. According to the special fertilizer for the drip irrigation of the asparagus, different formulations are adopted aiming at different growing periods, so that the special fertilizer is more targeted and more obvious in fertilizer effect, reasonable and comprehensive in proportioning of nutrient elements, stable in quality, good in water-solubility, and very suitable for drip irrigation; meanwhile, the fertilizer is saved, and the problem of soil environment pollution caused by excess fertilization and unreasonable fertilization is avoided.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizers, and relates to a special fertilizer for asparagus drip irrigation and a preparation and application method thereof. Background technique [0002] Asparagus is a perennial herbaceous plant. It can be cultivated once and benefited for many years. It mainly eats its tender stems. The tender stems of asparagus are fine in texture, soft and delicious in fiber, and have a unique aromatic flavor. It is a high-end nutritional and health-care vegetable. The asparagus planting areas in my country are mainly in the central and southern parts. However, due to the high rainfall and serious diseases in the south, which affect the yield and quality of asparagus, the planting areas are gradually moving northward. The northern region is rich in light and heat resources, but lacks water resources. In recent years, the northern region has begun to use drip irrigation facilities to grow as...
