Problems solved by technology

At present, the vast majority of natural rubber in our country is monocultured, and there is a very small amount of mixed rubber tea, but because of the poor quality of the tea, it is basically not used now.
Due to the large-scale monoculture of rubber forests, the diversity and stability of species have been destroyed, the service function of the ecosystem has declined, and its soil

Embodiment 1

[0038] A mixed forest method to increase the economic value of rubber plantations, including the determination of the mixed mode of rubber and agarwood, and the interplanting of pineapple, curcuma Herbaceous or small shrub commercial crops and young forest tending.

[0039] Step (1), determination of mixed planting mode: rubber is planted in wide and narrow rows, with a row spacing of 12 meters for wide rows, a row spacing of 4 meters for narrow rows, a plant spacing of 3 meters, and a planting density of 417 plants / hm 2 , the proportion of rubber tree species accounts for 40%; plant two rows of Agarwood between the wide rows, the row spacing is 3 meters, the plant spacing is 2 meters, and the planting density of Agarwood is 625 plants / hm 2 , the proportion of tree species accounted for 60% respectively; followed by band mixed, staggered planting.

[0040] Step (2), the cultivation of mixed afforestation seedlings: before the rainy season in May, carry out the cultivation of ...

Abstract

The invention provides a mixed forestation method for improving economic values of a rubber plantation. The method includes the steps of rubber and aquilaria sinensis mixed pattern determination, mixed forestation young growth (4-5 years after mixed forestation) pineapple, radix curcuma and flemingia macrophylla short-term herbal or under-shrub economic crop forest intercropping and young forest tending. The forestation method is simple, high in plant percent, good in growth trait expression and high in economic benefit at a mixed forestation young stand stage and has good improvement effectsof decreasing soil loss, improving soil fertility, improving water retaining capacity, increasing biological diversity, building multilayer multiple rubber compound ecological systems and controllingor relieving rubber tree disease and insect damage.

Description

Technical field: [0001] The invention belongs to the technical field of forest management, and in particular relates to an afforestation technology for logging sites and tropical mountainous areas, in particular to a mixed afforestation method for improving the economic value of rubber plantation forests. Background technique: [0002] Mixed afforestation refers to the selection of two or more tree species through different mixed configuration modes (such as star mixed, strip mixed, interrow mixed, block mixed, irregular mixed) according to the biological characteristics and interspecific relationship characteristics of different tree species. 7 models such as mixed with vegetation group) were artificially constructed on the forestation land, and each type of tree accounted for no less than 10% of the forest. Compared with pure forest, mixed afforestation can not only improve the absorption and utilization efficiency of nutrients, slow down soil erosion, maintain the stabili...
