Application of grease in promoting transplanting survival and growth of evergreen big trees

Abstract

The invention relates to the technical field of big tree transplanting, in particular to application of grease in promoting transplanting survival and growth of evergreen big trees. The grease is edible oil or purified waste oil, the evergreen big trees are evergreen coniferous big trees in a sand area, the edible oil or the purified waste oil is used for replacing a water-retaining agent, an antitranspirant, a nutrient solution and the like in the prior art, and the edible oil or the purified waste oil is applied to promotion of survival and growth of the evergreen big trees after transplantation for the first time, the transplanting survival rate of evergreen coniferous big trees in northern sand areas of elm cities is greatly increased, the planting time of evergreen coniferous trees innorthern sand areas of elm cities is prolonged, the growth amount of evergreen coniferous big trees transplanted in northern sand areas of elm cities in the rejuvenation period is increased, and theplanting cost of evergreen coniferous big trees transplanted in northern sand areas of elm cities is reduced.

Description

technical field [0001] The invention relates to the technical field of big tree transplantation, in particular to the application of oil in promoting the survival and growth of evergreen big tree transplantation. Background technique [0002] The sandy area in the north of Yulin City has a dry climate, large evaporation, low rainfall, and extremely inconvenient irrigation. The climate in spring is dry and rainless, with strong wind and sand; summer is long, high temperature and drought, and hot and dry; autumn is between summer and winter, and the time is short, and the annual rainfall is mostly concentrated in autumn; winter is cold and dry, with long freezing time, which leads to tree planting. The afforestation time is short and the survival rate is low. [0003] The best time for afforestation in northern Shaanxi is April, and the effective afforestation time is short. For the large trees after transplanting, it is often necessary to use water-retaining agents, anti-tr...

AI Technical Summary

Problems solved by technology

For the large trees after transplanting, it is often necessary to use water-retaining agents, anti-transpiration agents, nutrient solutions, etc. to promote the survival rate of large trees, but when using water-retaining agents, anti-transpiration agents, and nutrient solutions, defects such as cumbersome procedures and high costs often occur, and Can not thoroughly and effectively improve the survival rate of large tree transplanting and prolong the planting time, these two main reasons have caused serious obstacles to the large tree transplantation in the sandy area in the north of Yulin City

[0004] The water-retaining agent in the prior art is sprayed many times, the input quantity of nutrient solution is large, and the cost is high, thus causing certain economic pressure; , but because the evergreen trees transplanted in autumn have a short growth time in the year of transplanting, it is not easy to survive the winter, resulting in the phenomenon of freezing to death of transplanted trees
