Dedicated soil improver formula for northern brown soil newly built tea garden

Abstract

The invention discloses a dedicated soil improver formula for a northern brown soil newly built tea garden. The dedicated soil improver formula mainly comprises the following components in parts by weight: 11-14 parts of aluminum sulfate, 3-6 parts of monopotassium phosphate, 10-13 parts of ferrous sulfate, 3-6 parts of zinc sulfate, 28-35 parts of urea, 50-100 parts of humic acid, 50-70 parts of biochar and 100-150 parts of grass carbon. The dedicated soil improver formula for the northern brown soil newly built tea garden disclosed by the invention can be fully stirred, uniformly mixed and applied to soil before tea seedlings are transplanted half-month ago. By adjusting the soil structure and the physical and chemical properties, the viscidity and the pH value of soil are reduced; the content of organic matters is improved; and the growth of lateral roots of the tea seedlings is beneficially accelerated, so that the tea seedling transplant survival rate is improved.

Description

Technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special soil conditioner formula for newly built tea gardens in northern brown soil. technical background [0002] According to the division of tea regions in my country, most of the tea areas in the north of the Yangtze River in my country are brown loam soil, the soil is sticky, the pH value is generally high, generally between 6.5-7.0, and the tea tree is a kind of acid and alkali plant, suitable for tea planting soil The pH value should be below 6.5, and the most suitable soil pH value is between 4.0-5.5. Newly transplanted tea seedlings or newly sown tea gardens in northern tea areas often have problems such as difficulty in rooting and low survival rate, which makes young tea trees poorly grown and develops and seriously hinders the development of new tea gardens in northern brown soil. In order to develop tea gardens under higher pH soil conditions, increase the surviv...
