1. Introduction.
Peanut dry fertilizer is an organic fertilizer rich in nitrogen, phosphorus, potassium and other nutrients, its fertilizer efficiency is high, long-lasting, suitable for all kinds of soil and crops. The correct use of peanut dry fertilizer can improve soil fertility, promote crop growth, and improve yield and quality.
Second, how to use.
1.Time of application.
Peanut dry fertilizer should be applied in the early stage of crop growth, such as base fertilizer, spring top dressing, etc. For crops with a longer growing period, it can be reapplied in the middle of growth. The application time should be determined according to the growth characteristics of crops and the law of fertilizer demand, and should generally be applied before the critical period of crop fertilizer demand.
2.Method of application:
1) Base fertilizer: sprinkle a certain amount of peanut dry fertilizer evenly on the surface of the field, and then plough into the soil with a depth of about 20 cm. The dosage per mu is generally 200-300 kg, and the specific dosage should be determined according to soil fertility and crop type.
2) Top dressing: dissolve the peanut dry fertilizer in water and then water it at the roots of the crop. The dosage per mu is generally 100-200 kg, and the specific dosage should be determined according to the crop growth and soil fertility. At the same time, attention should be paid to controlling the concentration and avoiding root burning.
3) Foliar spray: dissolve peanut dry fertilizer in water, and then carry out foliar spray. This method is suitable for crops that are in urgent need of nutrient supplementation, but care should be taken to control the concentration and frequency of use. In general, the concentration should be controlled at 0Between 5% and 1%, spray about once a week.
3. Precautions.
1.Although peanut fertilizer is rich in nutrients, it may also carry germs and insect eggs, so it should be fully fermented and disinfected before use.
2.Peanut fertilizer contains a lot of organic matter and cellulose, so it can have a negative impact on some sensitive crops. A small area should be tested before use to ensure that there is no adverse effect on the crop.
3.The use of peanut dry fertilizer should be combined with soil fertility and crop growth to avoid problems such as soil salinization and soil compaction caused by excessive use. At the same time, attention should be paid to balanced fertilization with the use of other nutrients.
