Embodiment 1
[0014] This experiment was carried out in the Xiaokuashan River Basin of Shadi Village, Yuanmou County, Yunnan Province. This county is a typical dry-hot valley with an ecologically fragile area. The number of days is 349 days, the accumulated temperature of ≥10°C is 7786°C; the annual rainfall is about 630mm, concentrated in May-September, and there is little or no rain in other months, and the annual evaporation is 3811.2mm. The climate is dry, and the evaporation is 6 times the rainfall. Total solar radiation 641.8KJ / cm 2 , the sunshine rate is 62%; the dryness is 4.4 (calculated by Penman's formula).
[0015] Jatropha curcas, also known as tung tree, stinky tung tree, Jatropha curcas, and hibiscus tree, belongs to Jatropha curcas L, a plant of the genus Jatropha in the family Euphorbiaceae.
[0016] The water-retaining agent is a kind of artificially synthesized high-molecular polymer with super water-absorbing and water-retaining and releasing capabilities. Its English n...
Embodiment 2
[0023] Embodiment 2 (control 1)
[0024] Carry out by Jatropha curcas plantation building traditional method, but except not applying ripe farmyard manure, superphosphate, potassium sulfate to make base manure and water-retaining agent, other measures are identical with embodiment 1. See Table 1 for specific effects.
Embodiment 3
[0025] Embodiment 3 (control 2)
[0026] Embodiment 3 does not apply the water-retaining agent, but applies the base fertilizer. The composition and content of the base fertilizer are the same as those of the treatment 1, treatment 2 and treatment 3 in the embodiment 1, and other measures are the same as the embodiment 1. The specific effect See Table 1.
[0027] Table 1: the afforestation survival rate of each embodiment
[0028]
[0029] It can be seen from the above table that the afforestation of Jatropha curcas with water retaining agent in this area has an average survival rate of 96.95%, and the survival rate of Jatropha curcas afforestation without water retaining agent is 74.73%, with an average survival rate of 96.95%. An increase of 22.22%. Applying 4kg of cooked farmyard manure, 0.5kg of superphosphate, 0.5kg of potassium sulfate, and 25g of water-retaining agent had the best effect, and the survival rate of afforestation reached 98.45%.
