1. Look at the growth of the crops: The dark green leaves with thick green seedlings should not be applied with wax fertilizer. The young leaves with green and blue seedlings should not be applied or applied, and the leafy yellow-green thin seedlings should be replanted.
2. Look at soil fertility: P and K fertilizers should be applied to plots with low fertility, low base fertilizer, or plots without base fertilizer. For the year-round single application of chemical fertilizers, organic fertilizer should be added.
3. Look at the crop species: The application of wax fertilizer must vary from crop to crop. 1 Rapeseed: The manure and phosphorus fertilizers were mixed and rotted. From late December to early January, 1500 kg per acre was applied to the rapeseed rows, and the roots were mixed with the soil. Early maturing varieties should be applied earlier than late-maturing varieties due to early springing. 2 Wheat: In the middle and late December of December, 2500 kg of mixed fertilizer should be applied or applied per mu of Datian. Strong seedlings should be applied to strong seedlings, while weak seedlings and late-maturing wheat should be mixed with appropriate amount of phosphate fertilizer.

5. Appropriate mix of organic fertilizer and chemical fertilizer: decomposed pig dung, human waste, fermented pond mud, river mud, plant ash, and cake fertilizer are all high-quality organic fertilizers. For thin and thin seedlings, human feces and urine are added with nitrogen fertilizer. Mainly to promote seedling thick; strong seedlings should be pond mud, soil miscellaneous fertilizer based.
