Core Viewpoint - The wheat harvest in Cheng County, Gansu Province, is in full swing, with significant improvements in efficiency due to mechanization and scientific agricultural practices. Group 1: Wheat Harvesting Efficiency - The wheat harvesting period has begun in Cheng County, with 155,700 acres of wheat being harvested [1] - A mechanical harvester can complete the entire process of harvesting and threshing a 20-acre field in just 3 hours, compared to 5 days with 20 workers previously [1] - Approximately 70% of the wheat has been harvested, with expectations to complete the harvest in about a week [16] Group 2: Wheat Growth Assessment - The growth of wheat can be assessed using the "look, count, weigh" method, indicating healthy growth with an average plant height of around 60 cm [2][4] - Each wheat plant averages about 45 grains, with uniform and plump grains indicating sufficient nutrient supply during the filling period [4][6] - The estimated yield for the wheat fields is around 700 pounds per acre, consistent with last year's production [6][7] Group 3: Agricultural Practices - The local wheat varieties are drought-resistant and have been improved through a purification and rejuvenation program, achieving over 99% purity [9][11] - Scientific management practices include uniform sowing, fertilization, and pest control, contributing to standardized and green wheat production [11] - The use of various machinery in a coordinated manner has significantly increased harvesting efficiency [14] Group 4: Post-Harvest Utilization - After wheat harvesting, straw is quickly bundled and transported, with one acre yielding about 20 bundles, which can be used as livestock feed or for medicinal plant cultivation [16] - The integration of mechanization in post-harvest processes enhances income for farmers and promotes environmental sustainability [16]
