Abstract

The invention relates to a crop fertilizer applying technique, and provides a facility tomato water fertilizer applying method, which aims at solving the problems of unreasonable tomato fertilizer applying formula, different nutrient contents in the facility vegetable land with different planting ages, and using of empirical fertilizer applying as the main method. The facility tomato water fertilizer applying method is characterized in that organic fertilizers and inorganic fertilizers are applied; all organic fertilizers are used as base fertilizers, and part or all of inorganic fertilizers is used as a topdressing fertilizer; the total applying amount of the inorganic fertilizers is determined according to the age of a facility vegetable land; the total applying amount of the inorganic fertilizers includes the total amount of inorganic fertilizer used as the base fertilizer and the total amount of inorganic fertilizer used as the topdressing fertilizer which are respectively determined according to the age of the facility vegetable land; the topdressing period of the inorganic fertilizers is determined according to the growth and development phase of the tomato. The facility tomato water fertilizer applying method has the advantages that the total applying amount of the inorganic fertilizers in the tomato growth process is reduced, the utilization efficiency of the fertilizers is improved, the waste of the fertilizers is reduced, and the problem of difficulty in control of the existing tomato fertilizer applying method by a farmer is solved.

Description

technical field [0001] The invention relates to crop fertilization technology, in particular to a water and fertilizer fertilization method for facility tomatoes. Background technique [0002] At present, the method of fertilization in protected vegetable fields comes from testing the available nutrients in the soil, understanding the status of soil nutrient content, and fertilizing according to the test data and target yield. However, in actual production, few vegetable farmers understand the soil nutrient content, and it is difficult to base Soil nutrient content and unit output require nutrient amount and target output to calculate the tomato fertilization amount. Therefore, most vegetable farmers mainly use empirical fertilization. Due to the large amount of fertilization and low utilization rate of facility vegetables, nitrogen, phosphorus, potassium and other nutrients are accumulated in the soil. The longer it is, the more obvious the nutrient accumulation. [0003]...
