Special-purpose fertilizer for green cucumber

Abstract

The invention relates to a fertilizer specially used for cucumbers, aiming at providing a fertilizer used for cucumbers with reasonable mixture ratio of N, P and K, high utilization ratio of nutrient and nutrient release rate conforming to the fertilizer requiring rule of cucumbers. The technical proposal is that: the weight ratio of N : P2O5 : K2O in a compound / mixed fertilizer is 1 : 0.2 to 0.5: 1.2 to 1.6, the compound / mixed fertilizer contains 4 to 10 percent of fertilizer synergist, and the fertilizer synergist is attapulgite irradiated by ultrasonic wave of more than 20KHz and less than 50KHz for 1 to less than 5 min. The fertilizer specially used for cucumbers has wide applicability, can meet the requirement of the cucumbers in a whole growing season and is applied as a base fertilizer for one time, with obvious fertilizer-saving and production-increasing effects.

Description

A special fertilizer for cucumber technical field The invention relates to a fertilizer, in particular to a special fertilizer for cucumbers. Background technique Cucumber is a popular melon vegetable, and it is one of the main vegetables produced in the open field and in the greenhouse in the northern region. In recent years, due to people's blind pursuit of high yield and blind application of large amounts of fertilizer, the application ratio of nitrogen, phosphorus and potassium has been seriously out of balance, resulting in the accumulation of soil salt and waste of fertilizer. High fertilization means high loss of fertilizer, resulting in more serious environmental problems. According to reports, the utilization rate of nitrogen fertilizer in my country is about 30% to 50%, the utilization rate of phosphorus fertilizer is about 10% to 15%, and the utilization rate of potassium fertilizer is about 30% to 60%. There are many reasons for the low utilization rate of che...
