1. Applicable ammonium bicarbonate: The temperature in winter is low, and ammonium bicarbonate is not easily decomposed, which will help improve fertilizer utilization. Ammonium ammonium belongs to ammonium nitrogen fertilizer, which can be directly absorbed and utilized by crops after being applied to the soil, and has a rapid fertilizer effect. It belongs to a typical “quick-effect fertilizer†and can provide nitrogen nutrition to crops in time. Some people have experimented with applying ammonium bicarbonate in winter wheat fields, which is 1-1.5 times more effective than in high temperature seasons.
2, avoid application of urea: urea is ammonium ammonium phosphate, applied to the soil can not be directly absorbed by the crop, need to be converted to ammonium nitrogen in the soil under the effect of urease bacterial secretion of urea can be absorbed by the root system. Here, the rate of urea conversion mainly depends on the soil temperature at that time. Under normal circumstances, all urea applied to the soil is converted to ammonium nitrogen, which takes 7-10 days at a ground temperature of 10°C, and 4- at 20°C. For 5 days, it only takes 2-3 days at 30°C. It can be seen that crops are topdressed in winter or early spring. If urea is used, it will often affect the growth of crops because of slower fertilizer effect.
3. Increase phosphorus and zinc fertilizers: The absorption of phosphorus and zinc by crops is significantly affected by temperature and light. Low temperature in winter, lack of light, easy to induce winter crops lack of phosphorus, zinc, should be appropriate increase in phosphate fertilizer and zinc fertilizer. In addition, phosphorus can enhance the cold resistance of plants, and the increase of phosphate fertilizer also helps prevent crops from freezing.
MAGIK Lift Series are made of PDO (Polydioxanone), it is a thread with no cones, thus no damage to the tissue. This is the same thread used in Cardiac and other surgeries as sutures, and thus it is very safe.
