Application scenarios
Three Highs: Wide-Row Wheat, Deep Application of Chemical Fertilizers, and Multi-Functional Product Series
Wide-width wheat drills, deep fertilizer application equipment, and multi-functional product series—high efficiency, cost-saving, and superior performance. Models: 1.6–3.8 meters, totaling 40 models.
(1) This product is suitable for wheat sowing across China (except in the hilly and mountainous regions of southern China), reducing costs and boosting efficiency by 184 yuan per mu. It performs well under various soil conditions, including deep-plowed fields, cultivated fields, fields with hard residues, straw-covered fields, hard soils, and wet, clayey soils. In winter-sown areas, yields are 10-15% higher; in spring-sown areas and low-temperature regions, yields are 6-10% higher. Since 2023, this product has been listed as a key subsidized promotion item in Shaanxi Province and has been recommended to the national authorities. Starting in 2023, the National Promotion Headquarters held a demonstration in Beijing, comparing three types of drive-type row seeders, one conventional row seeder, and one wide-width fertilizer deep-injection seeder under identical standard conditions (see attached table).

Note: 1. From the data in the table, we can see that although no dead seedlings occurred in either plot, the mortality rate of wheat stems in the plot sown by the control machinery was higher than that in the plot sown by the experimental machinery—1.5 times higher than in the YAAO plot.
2. The reason this control group showed only a 5.6% increase in yield is:
(1) With unified deep plowing and land preparation, the advantages of YAAO’s meticulous cultivation cannot be fully demonstrated.
(2) With uniform application of chemical fertilizers, the effect of deep placement of YAAO fertilizers was not evident; instead, the advantages of wide-row sowing—improved ventilation and light penetration, as well as high tillering rate—were clearly demonstrated.
(2) Each business operator can increase net profit per quarter (taking the 250 model as an example): 4,620 yuan/quarter; 7 days × 10 hours × 2 quarters = 9,240 yuan/year.
Comparison of seedling emergence between YAAO wide-row seeding and traditional strip seeding machines:
As clearly shown in the above photo, the seedling band for wide-row seeding measures 13 centimeters, whereas the seedling band for conventional narrow-row seeding is only 3 centimeters. In other words, the seedling band for wide-row seeding is four times wider than that for narrow-row seeding. Yet, the area of empty space remains unchanged. This is precisely why the footprint per individual seed increases while the area of empty space stays constant—thus enabling better ventilation and light penetration, which in turn boosts tillering rates and leads to higher yields.
