Acidified soil improvement method for rubber plantation

Abstract

The invention discloses an acidified soil improvement method for a rubber plantation. The method comprises the following steps of: 1, selecting sowing time and green manure variety; 2, planting green manure, i.e., A, performing seed dressing by using symbiotic matching root nodule bacteria and phosphorus fertilizer before plantation of leguminous green manure; and 3, harvesting and burying the green manure, i.e., burying the harvested green manure in a dressing furrow and performing combined application of lime as a corrosion promoter in a burying process. The method aims at serious acidification of soil of the rubber plantation; meanwhile, no systematic control technology system is available at present; and the leguminous green manure with higher acid resistance and shading resistance is selected and used and application of microbial manure, DCD (dicyandiamide), the lime and the like is combined according to farm operation time process such as rubber plantation soil fertilization and winter management, so that the pH (Potential of Hydrogen) of the soil and contents of soil organic matter and the like of the rubber plantation are improved, thereby improving the acidified soil of the rubber plantation.

Description

technical field [0001] The invention relates to the technical field of agricultural science and technology, in particular to a method for improving acidified soil in rubber gardens. Background technique [0002] Soil acidification is a special manifestation of soil degradation. Soil overacidity will obviously affect the activities of microorganisms in the soil, the synthesis and decomposition of organic matter, the transformation and release of nutrient elements, the availability of trace elements and the ability of soil to retain nutrients, etc., thus affecting the quality of soil ecological environment and crop growth ( Jiang Zepu et al., 2003; Li Zaodong et al., 2009; Fan Qingfeng, 2009). [0003] Brazilian rubber tree is a perennial woody cash crop native to the tropics, with a growth cycle of 30-40 years. Generally, the row spacing of the rubber forest belt is 6m, the plant spacing is 3m, and the density of the grown rubber plantation is 70-80%. Rubber trees are acid-...

Problems solved by technology

However, for a long time, there have been few researches on the prevention and control techniques of soil acidification in rubber gardens, such as intercropping species, fertilization and soil conditioner application.
