Jitian Xingwen | Spring dyes the earth at the right time

Suzhou No.1 Satellite (Jitian Star A-03) and Jilin University No.1 Satellite (Jitian Star A-01) are the new generation of optical remote sensing experimental constellations independently developed by Jitian Xingzhou. The satellite is equipped with an independently developed "high timeliness, high geometry, high spectrum" optical camera, which has conventional and dynamic imaging capabilities. The ground panchromatic, multispectral, and hyperspectral resolutions are 3m, and the width is 15km.
Spring returns to the earth, and all things revive. From the hills of western Henan in March to the coast of Bohai Sea in April, farmland sheds the silence of winter and turns into interwoven color blocks of depth and shade. We look down upon this land through the eyes of Jitian, and write the most simple spring poems with furrows and ridges as pens and seedlings as ink.
In March, the hills in western Henan gradually turn green, and the terraced fields wrap around the mountains like a swirling green belt. The fields that have turned green from winter wheat are intertwined with the exposed brown soil, and the ridges of the fields are winding like fingerprints on the earth. The traces of the initial melting of spring water flow along the ditch towards the fields, injecting vitality into the land that has been silent for a winter.
Note: The farmland shown in the image in a bare state is a spring sowing plot that is about to be planted; The plot with green spots is the one where crops returned to green after being sown in winter last year
At the end of March, green winter wheat and silver white plastic film covered fields were neatly arranged on the Jiaodong Plain like black and white piano keys, playing a magnificent melody of spring plowing.
Note: The silver white strip plots in the image are covered with plastic film or greenhouse during spring sowing, and the green patches are the plots where crops returned to green after winter sowing last year.
In April, on the Weibei Plateau, the light brown spring sowing land and lush wheat fields are pieced together to form a colorful tapestry, as if nature and humans are holding brushes together, blending the spring atmosphere on the loess.
Note: The farmland shown in the image in a bare state is a spring sowing plot that is about to be planted. The plot with green spots is the one where the winter crops returned to green last year.
The spring irrigation in the northern plain of Henan is quietly spreading, and the crisscrossing field ridges are painting the regular fields into green chessboards of varying depths, sending the gift of spring water to every inch of land.
Note: The plot with green spots in the image refers to the plot where crops were replanted in winter last year.
On the banks of Bohai Bay, the coastal saline alkali land is undergoing a spring plowing scene of "improving soil and harvesting grain". The orderly strip fields and alkali drainage ditches form a precise grid, weaving a beautiful scroll of coexistence between humans and nature.
Note: Haixing County is located on the coast of the Bohai Sea. Due to its seaside location, the terrain is relatively low, and the groundwater is buried shallow with high salinity, which makes the soil salinization problem in the area more serious. The irregular patches in the wheat fields in the image are caused by poor growth of wheat due to salinization.
These spring plowing scenes frozen by satellites are the harmony of land and season, and the hopeful melody played by cultivators. As the green gradually blends the mountains and rivers, every ridge of land is the most sincere hope of the earth.
