According to Lu Shihua, an expert from the Soil and Fertilizer Institute of the Provincial Academy of Agricultural Sciences, in the case of drought, an important prerequisite for scientific fertilization is water-saving cultivation and water-saving irrigation. “It is necessary to use the water-saving agricultural technology as the basis to exert the production effect of fertilizer.†Lu Shihua said that in the severe drought last year, Xiangshui Village, Yanjiang Town, Yanjiang District, Ziyang City promoted the “water-saving and drought-resistant cultivation technology for rice filmâ€. The effect is very good: the field where the technology is implemented, the fertilizer has a very high production efficiency, and the grain yield per mu has generally reached more than 1,000 kg in the year of drought, and the highest level is more than 1,300 kg; instead of the field where the technology is implemented, Little or no grain is harvested.
At the same time, Lu Shihua also proposed three important principles of scientific fertilization in the case of drought:
Partial fertilization is applied once in a drought, which is likely to cause pollution in the field ground garden. If heavy rain occurs after the drought, the applied fertilizer is easily washed away, causing economic losses to the farmers and polluting the environment.
Deep application of fertilizer In the case of drought, if the fertilizer is applied only to the surface, the fertilizer is volatile. If there is heavy rain after a drought, it is easy to be washed away by the rain. Therefore, chemical fertilizer should be applied as deep as possible to maintain fertilizer efficiency.
Emphasis on the use of potassium fertilizer, boron fertilizer, potassium fertilizer can make crop leaf pores smaller, reduce water transpiration loss, is conducive to drought resistance. In addition, drought is easy to induce boron deficiency in crops, especially peanuts, fruit trees, rapeseed, etc. that are growing, and attention should be paid to the application of boron fertilizer.
Lu Shihua specially reminded farmers to do a good job in fattening after the disaster. “After suffering from drought, some crops have low yields or even no harvests, but there are still many nutrients remaining in the soil after the application of chemical fertilizers in the early stage. I advocate the use of straw covering technology to cover the soil to protect the residual fertilizer nutrients in the soil. â€
Huang Zelin, deputy director of the Soil and Fertilizer Division of the Provincial Department of Agriculture, suggested that in the case of drought, the majority of farmers should follow the guidance of the local technical department's soil testing formula, and according to the different conditions of the local soil, the shortage should be supplemented. Apply organic fertilizer. Because it can provide more complete nutrients for the soil, it also has drought resistance. In drought-heavy fields (such as sloping farmland), drought resistance is best."

Applying deep potassium fertilizer and boron fertilizer
During the spring ploughing season, the soil is affected by drought. How to apply fertilizer to fully absorb the crops? On the 13th, the reporter interviewed relevant experts from the Provincial Academy of Agricultural Sciences and the Provincial Department of Agriculture.
