Embodiment Construction

[0048] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0049]A method for improving acidified soil in a rubber plantation, comprising the following steps: Step 1: Sowing time and selection of green manure varieties: A. The shading degree of the mature rubber plantation is high. If sowing is carried out in early autumn, spring or summer, the green manure selection Green manure varieties with strong shade tolerance and a wide range of suitable pH; B, mature rubber plantations, if you choose to sow green manures in late autumn or winter, because the growth period falls in winter and mature rubber plantations fall leaves in w...

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-...
