Description
Technical Field
The invention belongs to the technical field of honey pomelo fertilizers, and particularly relates to a quality-improving and efficiency-improving fertilizer special for honey pomelos and an application method thereof.
Background
The honey pomelo is originally produced in famous places in Hei and xi provinces of Fujian province, and the Mi pomelo is more recognized as a Cheng-Ming brand in China and is evaluated as a famous agricultural product in China, which proves that the brand is successfully registered in 17 countries and becomes one of 10 geographical marking products protected by European Union in China. The honey pomelo has the characteristics of storage resistance, thin peel, much juice, sweet taste, pulp taste and the like, and has excellent quality, so the honey pomelo has higher economic added value. In recent years, the honey pomelo industry is rapidly developed, and the planting area of honey pomelos in peace county reaches 65 ten thousand mu, which accounts for about one third of the planting area in China.
However, with the continuous expansion of the planting area of honey pomelos, the phenomena of blind fertilization of fruit growers, excessive nitrogen, phosphorus and potassium fertilization and insufficient magnesium element fertilization commonly exist, so that a series of problems of element deficiency, fertilization and environment are caused. For example, fruit growers have shown that most fruit growers apply compound fertilizer formulations primarily 15-15-15 (N-P)2O5-K2O,%) can not completely meet the special nutritional requirements of the honey pomelos in different growth periods, such as higher nitrogen requirement in the flowering period and higher potassium requirement in the fruit stabilizing period; fruit growers generally do not apply fruit-picking fertilizer after picking fruits, so that the stored nutrition of trees is insufficient, and the blossoming and fruiting in the next year are influenced; most fruit growers are fertilized within a range of 150-180cm (water dripping line range) away from the trunk, and the root systems of the honey pomelos are mainly concentrated within a range of 20-80cm away from the trunk (figure 1), so that the honey pomelos are difficult to effectively absorb fertilizer nutrients, fertilizer waste is caused, soil acidification is serious, nitrate leaching is serious, soil phosphorus is excessively accumulated, and grass growing in an orchard is difficult to grow due to fertilizer over-treatment (figure 2). In addition, most fruit growers do not apply magnesium fertilizer basically or no magnesium element is added in the fertilizer, and the effective magnesium content in soil is low, so that the symptoms of magnesium deficiency of trees are serious, and the growth and the fruit quality are influenced. Therefore, at present, fertilizer efficiency reaction research according to the growth and development rule, nutrient demand rule and soil nutrient supply condition of honey pomelos is urgently neededThe special fertilizer for honey pomelo production is beneficial to fruit growers to save fertilizer consumption, improve the yield and quality of honey pomelo, improve nutrient utilization efficiency and reduce environmental pollution and carbon emission.
