Cucumber

There are three treatments in the cucumber fertilization experiment: no fertilization, conventional fertilization, and application of potassium humate - containing organic compound fertilizer. At the seedling stage, the conventional fertilization treatment drenches 6 kg/mu of ordinary compound fertilizer without humic acid, and the treatment with potassium humate - containing organic compound fertilizer drenches 6 kg/mu. At the early flowering stage and harvest stage, the conventional fertilization treatment broadcasts 25 kg/mu of ordinary compound fertilizer without humic acid once a week, and the treatment with potassium humate - containing organic compound fertilizer broadcasts 25 kg/mu once a week.

Analysis of Test Results (Impacts on Seedlings, Fruit Quality, and Yield)

Figure 3: Effects of conventional fertilization (CK) and FA-K application on cucumber fruit growth rate 

Note: Diagram A = Comparison of cucumber fruit length between conventional fertilization and FA-K application within 14 days of fertilization; Diagram B = Final growth status of cucumber fruits under the two fertilization treatments

Compared with the no-fertilization and conventional fertilization treatments, the cucumber seedlings treated with potassium humate-containing organic compound fertilizer are stronger, with darker green leaves, and the fruits are plumper, more uniform, longer and thicker.
