The results indicated that soil improver could optimize soil aggregates structure, decrease soil bulk density, soil pH and soil salt content, increase soil organic matter and 1 000-grain weight, thereby enhancing wheat yield. With the increase of soil improver application amount, soil physical-chemical properties became better and wheat yield increased. However, there was no significant difference in the treatments with the application amounts of 3%, 4% and 5%. In addition, the treatment of reducing nitrogen showed no superiority in soil physical-chemical properties and wheat yield, indicating that sufficient nitrogen was essential for the growth of wheat.展开更多

We break through key core technique of farming and agriculture,and invent new method of Fenlong tillage. Broad-spectrum Fenlong tillage technique system based on "full-layer and bottom-layer superdeep tillage without disturbance of soil layer" is established,which provides the possibility for establishing "modern Fenlong agriculture". When applied in 35 kinds of crops in 24 provinces of China,yield could be increased by 10%-50%,and even 1 times. In the transformation of severe saline-alkali land,corn yield could increase by 73. 0%,and Na,Cl and Mg ions in grain decrease by 20. 81%,1. 47%,and 9. 36% respectively. The newly developed "scarification tillage( reclamation) in the bottom area" could cover "bottom tillage" of dryland,paddy field,degraded grassland,perennial sugarcane,forest and fruit land,traditional Chinese medicine land,and ecological reconstruction of desertification land. It is point out that if Fenlong technique is used in 666 666. 67 km2 of farmland,200 000 km2 of saline-alkali land,666 666. 67 km2 of degraded grassland,and fisheries in rivers and offshore waters are used,trillion yuan of Fenlong economy could be formed,and the nationals will walk towards a healthier new era.Fenlong technique involves agriculture,forestry,water,grass,environment and other aspects,and its global promotion could improve eco-environment and change world development pattern.展开更多
