Mistake 1: The new roots of the vine have not been grown yet. Excessive application of fertilizer before the new roots grow will, on the one hand, lead to difficulty in water absorption of the seedlings and, on the other hand, will lead to difficulties in the growth of new roots. In the event of high temperatures, the above-ground parts will die and die. Before the new root grows, it is only suitable for foliar supplementation, and it can be sprayed with 500 times urea water and 600 times potassium dihydrogen phosphate. Mistake 2: Immediately after germination, a large amount of fertilizer is used to water. If a large number of fertilization and watering are selected after germination, the soil temperature will be lower, the root absorption capacity will be worse, and the root system itself will be less and weaker, and eventually the more watering and fertilizing fruit trees will not be. At this point to breathe loose soil, increase the temperature, at the same time to give the foliage nutrition. Error 3: The treetop or the entire tree is yellowed with blind iron. Foliar iron supplementation is a blind behavior and cannot replace the absorption of roots. It can only be a temporary solution. At the same time, if the amount of fertilizer is too large, it is easy to burn roots. In this case, the first problem to be solved is the problem of soil permeability and vitality of the root system. Loose soil and evacuation are effective measures. Error 5: The soil is seriously acidified and acidic fertilizers are applied. If the soil has been acidified, it is not appropriate to apply physiological acidic fertilizers again. It should be regulated by physiological alkaline fertilizers, which can be used alone or in combination with other fertilizers. Mistake 6: Fertilization with high temperature and lack of crops. High temperatures, poor soil moisture content, if not timely irrigation after fertilization, the roots absorb large concentrations of fertilizer, prone to post-fertilization leaf margin coking phenomenon, if the late rain, leaf disease occurs seriously, and even cause the leaves to fall. Error 7: The balance of fertilizer application is incorrect. The amount of nitrogen fertilizer should be applied when the leaf is hypertrophy and green color. The fruit coloring period is mainly phosphorus and potassium fertilizer. Appropriate amount of nitrogen, phosphorus and potassium compound fertilizer is applied after fruit is harvested to promote the early restoration of fruit tree function and prevent premature aging.

Error 4: Only drip fertilizer without driping water when drip irrigation. Individual fertilizers are added to the individual orchards at the time of drip irrigation, and the drip of fertilizer immediately stops the drip of water. As the amount of water in each drop is limited, the evaporation of water on the surface causes the concentration of fertilizer in the soil to become higher and higher, eventually causing the roots to burn out. The integration of water and fertilizer should be preceded by drops of water before the first 15 minutes of water.
