Abstract

The invention discloses a method for homogenizing soil moisture of test fields in hilly areas of the middle and lower reaches of the Yangtze River. The method includes the steps of 1, investigating the characteristics of underground water around the test fields; 2, excavating earthworks; 3, building wall bodies; 4, dumping earthworks; 5, hardening a headrace channel; and 6, arranging water inlet and outlet channels. The method is simple, practicable and convenient to operate and can solve the problem that the difference of the soil moisture is large and causes repeated parallel errors because relative positions of the test fields are different.

Description

technical field

[0001] The invention relates to the technical field of hilly agriculture in the middle and lower reaches of the Yangtze River, and more specifically relates to a method for making soil moisture uniform in a test field in the hilly area of ​​the middle and lower reaches of the Yangtze River. Background technique

[0002] Most of the hills in the middle and lower reaches of the Yangtze River belong to the northern subtropical zone, and a small part belongs to the northern margin of the middle and lower subtropical zone. The annual average temperature is 14-18°C, the coldest monthly average temperature is 0-5.5°C, the absolute minimum temperature is -10--20°C, the hottest monthly average temperature is 27-28°C, and the frost-free period is 210-270 days. Agriculture has two crops or three crops a year, and the annual precipitation is 1000-1400 mm, concentrated in spring and summer. Zonal soils are only found in low hills and gentle hills, mainly yellow-brown soi...
