When a small amount of attention is paid to the balanced fruit trees, the application of the water-soluble fertilizer should be carried out in small amounts to reduce the leaching loss caused by one-time large-scale fertilization. Water soluble fertilizers are usually applied, drenched or applied by irrigation equipment. Especially under drip fertigation conditions, the roots grow densely and in large quantities. At this time, the dependence on soil nutrient supply is reduced, and more depends on the nutrients provided by drip irrigation. If the formula is not balanced, it will affect crop growth. Reasonable irrigation to avoid excessive irrigation, in general, the root depth of the fruit tree can be kept moist. Excessive irrigation wastes fertilizer, and crop yield reduction, especially urea and nitrate nitrogen fertilizer, is easily lost with water. When applied in combination with other fertilizers, usually the water-soluble fertilizer is used as a top dressing, and water-soluble fertilizer is not used as a substitute for other fertilizers. Precautions for drip fertilization First, when drip fertilization, first drip the water, and then start fertilizing after the pipe is filled with water. Immediately after the end of fertilization, the water is dripped for 20 to 30 minutes, and all the residual fertilizer in the pipeline is discharged. Secondly, long-term use of drip irrigation in greenhouse fruit trees will cause accumulation of surface salt and affect root growth. Under-film drip irrigation can be used to inhibit salt migration to the surface layer. Third, pay attention to the uniformity of fertilization. In principle, the slower fertilization is better.
