EFFECTS OF ENZYME PREPARATION ON TEA YIELD AND SOIL FERTILITY

This paper uses the field trial method to study the effects of applying different doses of enzyme (ie, water, 50 times solution, 100 times solution, 150 times solution, 200 times solution and 250 times solution) on tea yield and basic soil fertility. The results showed that: compared with CK (clear water) treatment, the application of different doses of enzyme can increase the bud density of tea gardens by 3.7%-26.3%, the hundred bud weight by 3.9%-21.8%, and the internode length by 5.4%-23.1%; and the organic matter of the cultivated layer soil of tea garden increased by 2.6%-31.8%, the alkali hydrolyzed nitrogen increased by 13.9%-98.3%, the available phosphorus increased by 26.4%-98.7% and the available potassium increased by 24.6%-102.5%.
