Special fertilizer for melons in protected fields

Abstract

The present invention relates to a special fertilizer for melons in protected fields. The special fertilizer is prepared from organic fertilizer, diammonium phosphate, superphosphate, urea, potassium sulfate, secondary elements, trace elements, a soil modifier and an anti-cropping agent mixing with each other; and the weight ratio of above raw materials is: 300-400 parts of organic fertilizer, 3-5 parts of diammonium phosphate, 4-6 parts of superphosphate, 2-4 parts of urea, 2-4 parts of potassium sulfate, 0.3-1 parts of secondary elements, 0.05-0.3 parts of trace elements, 0.1-0.5 parts of the soil modifier and 0.1-0.5 parts of the anti-cropping agent. The special fertilizer for melons in protected fields has a rational combination, can fully meet the nutritional needs of the melons in whole growth period; and is conducive to the absorption by the root system, thereby improving the utilization rate of the fertilizer. By applying the fertilizer, melons produced are large in size, regular and uniform in shape, and sweet and fresh in taste, thereby having relatively high economic benefits and nutritional value.

Description

technical field [0001] The invention relates to a vegetable fertilizer, in particular to a special fertilizer for protected melons. Background technique [0002] The muskmelon in the protected area grows for a long time, the ambient temperature is high, and its root system is underdeveloped, and the absorption capacity of the root system is weakened in the later stage of growth. The existing fertilizer varieties in production cannot meet the requirements of the muskmelon in a targeted manner. As a result, the fertilizer utilization rate is low, the soil salt accumulation is serious, and the disease increases, which affects the healthy development of vegetable production. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a special fertilizer capable of meeting the nutrient requirements of the protected muskmelon during the whole growth period. [0004] The technical scheme adopted by the present invention to solve the te...
