The loss caused by drought in China exceeds the sum of all other environmental factors, and the drought becomes an important factor for restricting the agricultural production and development in China. The term waterlogging generally includes two layers. One means that the water content of the soil exceeds the field water holding capacity, the soil water is in a saturated state, the root system completely grows in the swamp mud, and the waterlogging damage is wet damage and is also called waterlogging damage. The other means that the water not only fills the soil, but also is accumulated on the ground in the field, and the partial or whole plant of the crop is submerged, which is generally called "waterlogging". According to the report of the food and agriculture organization of the United nations and the estimation of the world soil map drawn by the international soil society, the soil with excessive water accounts for about 12 percent of the world soil. Since 2010, 28 provinces (regions and cities) in China suffer flood disasters, and the disaster area of crops reaches 760 ten thousand meters2. Under the conditions of drought and waterlogging, the roots of crops are in a water-deficient or oxygen-deficient state, and are easy to wither and rot, and even more, the crops die in a large area, the yield is reduced, and the income of farmers is seriously influenced.
The fertilization can not only improve the soil fertility, but also is an important measure for improving the yield of crops in unit area. Fertilizers are the most basic and important material inputs for agricultural production. However, the existing fertilizers mainly comprise: the fertilizer is high in inorganic nutrients, but only provides nutrients, and does not play a role in soil improvement and crop growth promotion and quality improvement. And the other is organic fertilizer which has a certain effect on soil improvement, but needs to be applied with simple substance fertilizer or compound fertilizer to provide nutrients. The fertilizer has single function and low utilization rate, can not stimulate the activity of crop roots and improve the growth of crops, has certain harmful effect on soil after long-term use, leads to the fact that the soil can not be used for a long time, and influences the ecological environment.
