Winter is the best time to apply wax fertilizer to crops. Attention should be paid to the following points when applying wax fertilizer: 1. Look at the growing trend of the crops: The long green leaf color should not be applied to the wax fertilizer, and the dark green seedlings should not be applied or applied. Thin green and yellow leafy seedlings must be replanted. 2, see the soil fertility: high fertility, the foot of the foot at the foot of the plot can be less or no application of wax fertilizer; low fertility, base fertilizer less plot or no application of base fertilizer plot to increase phosphorus and potassium fertilizer. For the year-round single application of chemical fertilizers, organic fertilizer should be added. The application of paraffin fertilizer to sandy soil is repeated several times to prevent loss of fertilizer leaching. 3, see the crop species: 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. 4, see the weather: the temperature is lower, the application of delayed manure, compost, pond mud, ash or animal and manure urine; when the temperature is high, grab the sunny and easy decomposition of urea, ammonium chloride, ammonium bicarbonate Fertilizers. 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 should be added with nitrogen fertilizer. Mainly to promote seedling thick; strong seedlings should be pond mud, soil miscellaneous fertilizer based. Organic manure is used as a wax fertilizer and should be concentrated in the roots to prevent seedlings from drying out.
