Moreover, the tilth soil is uniform in size and in small, broken bits and loose. It expands the new soil ＂four warehouses＂ （namely soil nutrient warehouse, water warehouse, oxygen warehouse and microbial warehouse）, and under the conditions of ＂three no increase＂ in chemical fertilizer and pesticide, irrigation water and labor input, various crops show a increase of 10%-30% in yield （average increase by 25.48% in the 23 rice, wheat and corn planting areas of several provinces）, 5% in quality, and 1 time in water retention. And the sustainable production-increasing ef- fect lasts 2-3 years after once Fenlong tillage, with the comparative efficiency reaching about 20%. It is suggested using Fenlong to activate the arable land, saline land grassland and rivers resources, so as to drive the construction of green agriculture ＂3＋1＂ industrial system, which can promote the realization of the increases in available agricultural resource stock, quality food resource stock and available water resource stock in China and even in the world, realize the ＂two responses＂ to ecological environment deterioration and climate warming, and achieve the harmonious coexistence of human beings and nature.展开更多
