Problems solved by technology

At the same time, weeds, miscellaneous shrubs and other plants grow faster in tropical and subtropical regions, and there are more types of ants. These factors lead to a low survival rate and preservation rate after direct sowing of Jatropha seeds for afforestation, and it is almost impossible to form a forest
Now commonly used jatropha afforestation methods mainly choose to use bare-root seedlings or nutrient bag seedlings for afforestation during the rainy season, which not only requires a lot of manpower and material resources to transport the seedlings up the mountain, but also costs a lot
Moreover, due to the lack of water sources in the mountains, it is impossible to ensure sufficient rooting water. Once there is no rain within 2 to 3 days after planting, it is extremely difficult for the seedlings to survive.

Embodiment 1

[0016] In Huina Jatropha seed afforestation demonstration area in Menghai County, Xishuangbanna, soaking on-demand afforestation experiments were carried out, and conventional afforestation techniques were used as a comparison. The survey results of afforestation survival rate and cost are shown in Table 1 and Table 2. The specific operation process is as follows:

[0017] (1) Comprehensively clean up the logging sites

[0018] Cut and irrigate barren hills and wasteland from January to February, and make mountains in early April. Mountain refining can carry out comprehensive disinfection, increase fertility, loosen the topsoil layer, and provide convenience for site preparation and afforestation.

[0019] (2) Seed soaking

[0020] In late May, about 10 days before afforestation, soak Jatropha seeds with 100 times carbofuran solution for 48 hours, and dry the soaked seeds for later use.

[0021] (3) Selection of afforestation time

[0022] At the beginning of June, one wee...

Embodiment 2

[0031] Repeat embodiment 1, have following difference: Jatropha seed is soaked 45 hours with 100 times of carbofuran solution.

Embodiment 3

[0033] Repeat embodiment 1, have following difference: Jatropha Jatropha seed is soaked 50 hours with 100 times of carbofuran solution.

Abstract

The present invention discloses dot sowing forestation method of small tung. The dot sowing forestation method includes preparing land for foresting, soaking small tung seed in 100 times of furadan solution for 45-50 hr, dot sowing and conventional fertilizer and water management. The said method has fast germination, high germination ability, capacity of avoid ant harm and high foresting survival rate and excellent application foreground, and is suitable for different kinds of land.

Description

technical field [0001] The invention relates to tropical and subtropical mountain afforestation techniques, in particular to a method for on-demand afforestation with jatropha seeds. Background technique [0002] Jatropha curcas, also known as Jatropha curcas, Jatropha curcas, black soap tree, wood peanut, reed seed, old fat fruit, etc., belongs to Euphorbiaceae (Euphorbiaceae) Jatropha deciduous shrubs or small trees . It is native to tropical America, and now there are a small amount of cultivation or escape in Yunnan, Hainan, Guangdong, Guangxi, Sichuan and Guizhou in China. The oil content of Jatropha seeds is 30% to 35%, and the main components of oil are oleic acid, linoleic acid and palmitic acid, of which the content of oleic acid is about 40%, the content of linoleic acid is about 30%, and the content of palmitic acid is about 20%. Jatropha was mainly used to make soap and organic high nitrogen fertilizer in the past. Modern research has found that its oil can be...
