1, as the growth of the object: the leaves of the green color of the long seedlings should not be applied to the fertilizer, the leaves of the green and strong seedlings are less or not applied, the leaves of yellow-green thin and weak seedlings should be re-applied.
2, look at the soil fertility: high fertility, the bottom of the fat foot of the plot can be less or not applied to the fertilizer; low fertility, less fat on the plot or no plot of fertilizer to increase the application of phosphorus and potassium fertilizer. Perennial single application of chemical fertilizers should be increased by applying organic fertilizer. The application of wax fertilizer in sandy soil should be carried out in small amounts to prevent loss of fertilizer leaching.
3, as the type of matter: the application of wax fertilizer must be different depending on the crop. 1 Rape: Mix the manure and phosphate fertilizer to make rotten. From the end of December to the first day of January of the next year, use 1500 kg of strips per acre to apply to the rapeseed line. Early-maturing varieties should be applied earlier than late-maturing varieties due to early spring. 2 Wheat: In the middle and late December, 2,500 kilograms of soil is applied per acre of field or mixed soil, and the strong seedlings should be mixed with soil, while weak and late-maturing wheat should be mixed with appropriate amount of phosphate fertilizer. 3 green manure: apply 150-250 kg of ash fertilizer per acre of field or apply a thin layer of pig and cow manure.
4, see the weather: the temperature is lower, the application of delayed manure, compost, pond mud, gray fertilizer or human and animal excrement; when the temperature is high, grab the sunny day to apply easy decomposition of urea, ammonium chloride, ammonium bicarbonate Wait for fertilizer.
5. Reasonable combination of organic fertilizer and chemical fertilizer: decomposed pig manure, human excrement, fermented pond mud, river mud, fire ash, cake fertilizer, etc. are all high-quality organic fertilizers. For thin and weak seedlings, human feces and urine should be added with nitrogen. Mainly chemical fertilizers, promote seedlings and strong; for strong seedlings should be based on pond mud, soil and fertilizer. Organic fertilizers should be used as wax fertilizers to avoid concentrated application to the roots to prevent burning of seeds during drought.
