Stump reserving bud afforestation method for cutting poplar industry raw material forest

Abstract

The invention relates to the technical field of afforestation, in particular to a stump reserving bud afforestation method for cutting a poplar industry raw material forest. The stump reserving bud afforestation method comprises a first step of cutting poplars in the poplar industry raw material forest before sap flows in spring, reserving stumps, and enabling the tops of the stumps to be higher than the ground; a second step of enabling the soil to be covered on the stumps, and enabling the thickness of the covering soil to be higher than the tops of the stumps; a third step of instantly irrigating the poplar industry raw material forest where the soil is covered; a fourth step of performing intertillage on the poplar industry raw material forest undergoing natural reforestation; and a fifth step of enabling the growth height of buds of the stumps to be 8cm to 10cm. According to the stump reserving bud afforestation method, the complex afforestation process of digging original stumps, flattening land, digging planting holes, purchasing seedlings and planting is not required, the afforestation cost is reduced, the tree nutrition absorption area is large by reserving huge root systems of the original trees, growth of the trees is accelerated after the renewed trees grow normally, the cutting cycle is shortened simultaneously, and production benefit is greatly improved.

Description

technical field [0001] The invention relates to the technical field of tree planting and afforestation, and relates to a method for afforestation of poplar industrial raw material forests by cutting stakes and leaving buds. Background technique [0002] my country is a big producer of wood and wood products in the world, and it is also a big consumer. At the same time, it is a country with very little forest (timber) resources per capita. Since 1998, the state has started to implement the natural forest resources protection project in key areas, and has taken measures to reduce domestic forests year by year. 67% of the forestry land in key areas has been designated as ecological protection areas, forest logging in prohibited logging areas has been completely stopped, the total supply of commercial timber in the country has shrunk by 1 / 3, and there is a large supply gap in the timber market. Mr. M.Viart, chairman of the International Poplar Committee, believes that "poplar i...

Problems solved by technology

[0004] The invention provides a method for afforestation of poplar industrial raw material forests by cutting stakes and leaving buds, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problems of high afforestation cost, long growth period and low production efficiency of traditional poplar industrial raw material forests. The traditional tree replacement pile renewing afforestation and leaving the pole is easy to split with the original pile or the forest is not neat
