1. Fruit dressing during fruit set-up: Fruits grow rapidly after the first fruit set, so whether the fertilizer is sufficient or not has a direct influence on the size of the fruit or the level of yield. Adequate nutrition can accelerate cell division and increase the volume, such as fertilizer and water shortage, it will affect the development of the fruit and even drop fruit. Therefore, top dressing during young fruit period not only affects the level of yield, but also relates to the quality of the fruit. The top dressing is suitable in mid-July. In addition to topdressing nitrogen fertilizer, phosphorus and potash fertilizers can be used in combination to meet the needs of the development of jujube trees for phosphorus and potassium and improve fruit quality.
Second, the top-dressing: Top dressing in August to September is particularly important to promote fruit growth before the maturity, increase fruit weight and tree nutrient accumulation, especially for the more plants can not be ignored. Late-stage topdressing not only benefits the increase in yield and quality, but also has a good impact on the growth and results of the following year. The top-dressing can be sprayed with nitrogenous fertilizer and combined with a certain amount of phosphorus and potassium fertilizers.
Third, the autumn basal fertilizer: harvest before the best basal fertilizer, this time, the leaves still have a higher photosynthetic efficiency, sunny, autumn air, large temperature difference between day and night, is conducive to the accumulation of organic nutrients to meet the bud, flower bud differentiation in the following year Need for flowering and fruit setting. In autumn, basal fertilizers should be dominated by organic fertilizers such as ring fertilizers and soil excreta. At the same time, appropriate fertilizers should be applied to some of the available fertilizers.
