Method for researching influence of soil moisture on diameter growth of Larix gmelinii trunk

Abstract

The invention discloses a method for researching influence of soil moisture on diameter growth of a Larix gmelinii trunk. The method comprises taking samples of Larix gmelinii, measuring the soil moisture, measuring the diameter of the Larix gmelinii trunk and analyzing the data dependency. The Larix gmelinii sampling step includes sample preprocessing, interference of the external environment and loss of moisture in the Larix gmelinii cuticle are reduced, furthermore, the soil moisture and the Larix gmelinii trunk diameter can be measured accurately in real time, and a reliable theoretical basis is provided for data dependency analysis. The method for researching the influence of soil moisture on the diameter growth of the Larix gmelinii trunk is simple to operate and clear in mind, and can be widely applied to plantation and research of Larix gmelinii forests, and plays an important role in increasing the survival rate of Larix gmelinii and promoting the Larix gmelinii trees to grow.

Description

technical field [0001] The invention belongs to the field of ecological environment research, and specifically relates to a method for studying the influence of soil moisture on the growth of larch trunk diameter. Background technique [0002] Larch is a deciduous tree of the genus Larix in the family Pinaceae. It is a tree species in cold temperate and temperate zones. It likes light and strong positive planting. It has strong adaptability and a wide range of adaptability to soil moisture and nutrients. Its wood is heavy and solid, and it is resistant to compression and bending. It has high strength and high wood craft value. It is an excellent material for poles, sleepers, construction, etc. It can also be used to make arabinogalactan, which has strong economic benefits. [0003] Larix is ​​planted in a large area in my country. It is one of the important forest tree species and is widely distributed in Northeast China, Inner Mongolia and other regions. Due to the warming...

Problems solved by technology

[0004] The traditional method is to study the monthly average rainfall and the rough change of larch trunk diameter, and draw analysis based on the relationship between the two. This method can only roughly estimate the relationship between its influence and change, and cannot specifically explore its correlation. In order to realize the exploration The concrete correlation of soil moisture and larch trunk diameter, proposed a kind of research soil moisture of the present invention to the method that the influence of larch trunk diameter grows, can monitor soil moisture change and larch trunk diameter change in real time, utilize linear regression equation Correlation analysis by which regulation of soil moisture by irrigation can promote larch trunk diameter growth
