Embodiment 1

[0031] In 2014, in Wangli Village, Taiping Town, Pingguo County, Guangxi, we promoted non-refined afforestation and close-to-natural forest management techniques in Wangli Village, Taiping Town, Pingguo County, Guangxi, and built Rendou public welfare forest. The survival rate of afforestation was only 12%.

[0032] In November 2015, afforestation site preparation was carried out. For forest land clearing, clump clearing is adopted, centering on the planting point, weeds, shrubs or logging residues within a radius of 60cm~80cm are cleared and piled up. Hole-shaped soil preparation, the size of the planting hole is 40cm-50cm long x 40cm-50cm wide x 30cm-40cm deep, and the topsoil and core soil are stacked separately on the edge of the hole. Planting density 1667 plants / hm 2 , the afforestation density is determined after deducting the area that cannot be afforested in the afforestation land with bare rocks.

[0033] In January 2016, base fertilizer was applied. Before planti...

Embodiment 2

[0039] In 2015, in Wangli Village, Taiping Town, Pingguo County, Guangxi, the karst shrub and grass mountainous area promoted the management technology of non-alpine afforestation close to natural forest, and built Rendou public welfare forest.

[0040] In November 2015, afforestation site preparation was carried out. For forest land clearing, clump clearing is adopted, centering on the planting point, weeds, shrubs or logging residues within a radius of 60cm~80cm are cleared and piled up. Hole-shaped soil preparation, the size of the planting hole is 40cm-50cm long x 40cm-50cm wide x 30cm-40cm deep, and the topsoil and core soil are stacked separately on the edge of the hole. Planting density 1200 plants / hm 2 , the afforestation density is determined after deducting the area that cannot be afforested in the afforestation land with bare rocks.

[0041] In January 2016, base fertilizer was applied. Before planting, combine with the soil returning process, backfill the surface ...

Embodiment 3

[0047] In 2015, in Wangli Village, Taiping Town, Pingguo County, Guangxi, the karst shrub and grass mountainous area promoted the management technology of non-alpine afforestation close to natural forest, and built Rendou public welfare forest.

[0048] In November 2015, afforestation site preparation was carried out. For forest land clearing, clump clearing is adopted, centering on the planting point, weeds, shrubs or logging residues within a radius of 60cm~80cm are cleared and piled up. Hole-shaped soil preparation, the size of the planting hole is 40cm-50cm long x 40cm-50cm wide x 30cm-40cm deep, and the topsoil and core soil are stacked separately on the edge of the hole. Planting density 1450 plants / hm 2 , the afforestation density is determined after deducting the area that cannot be afforested in the afforestation land with bare rocks.

Abstract

The invention provides a forestation method characterized by bagging seedlings for protecting the seedlings against crickets and cutworms. The method comprises the steps of adopting block clearing and pit-shaped soil preparation in the autumn and winter of the last year; applying 0.2kg-0.3kg of base fertilizer to each pit; in January-March of the next year, planting seedlings on the conditions that soil is drenched after raining or rainy days continue successively for forestation; inserting four bamboo sticks 60cm long in a square shape with each seedling as the center, bagging each seedling with a high pressure polyethylene transparent flat opening bag which has openings at two ends and has a width of 40cm and a length of 50cm-60cm, wherein the bottom bag opening is pressed tightly by using fine soil and the top end bag opening is fixed to the four bamboo sticks by tying and binding of galvanized iron wire. The method has the advantages that seedlings are protected via bagging and artificial isolation barriers are built, so that intrusion of underground pests such as crickets and cutworms can be prevented; the insect control effect reaches 100%; the method causes no pollution to environment, and does not kill and injure pests and natural enemies, thereby protecting ecological balance and promoting sustainable development of forestry; the method is low in cost, simple in operation and remarkable in effect, is easy to promote and popularize and has high ecological benefit, social benefit and economic benefit.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and in particular relates to an afforestation method for protecting seedlings by bagging and preventing crickets and cutworms. Background technique [0002] China is one of the countries in the world where forest diseases and insect pests occur more seriously. The occurrence area of ​​forest diseases and insect pests has been on the rise. In the 1950s, the occurrence area of ​​forest diseases and insect pests in China was 1 million ha 2 , which rose to 11 million hm in the 1990s 2 , with an average annual increase of 25%, has become one of the important factors restricting the sustainable development of China's forestry. There are more than 8,000 types of forest diseases and insect pests in China, of which more than 200 often cause serious damage, posing a huge threat to China's forest resources, ecological environment and natural landscape. [0003] In recent years, the promotion of ...
