Whether the pitaya can blossom and bear fruit quickly depends on reasonable fertilization, and attention must be paid to timely and appropriate fertilization. \x0d\ \x0d\ 1. Timely fertilization: Pay attention to the period of fertilization to avoid waste, failure or even counterproductive. Generally, it should be applied more in the growth, flowering and fruiting seasons, but not or less in the winter dormancy season. Thin fertilizer should be applied frequently during flowering and fruiting period. \x0d\ \x0d\2. Appropriate fertilization: All kinds of organic fertilizers must be fully fermented and decomposed before application. Single fertilizer should be avoided when applying fertilizer. It is not advisable to apply a large amount of nitrogen fertilizer in flowering and fruiting seasons to avoid causing vines to grow in vain without flowering and fruiting. Although humus fertilizer contains more balanced nutrients, it is not suitable to apply some manure, but all kinds of organic fertilizers should be mixed, otherwise it will produce antagonistic effect of nutrients. \x0d\\x0d\3. Avoiding element deficiency disease and antagonism: \x0d\ Any plant's demand for various nutrients has a limited relationship, and the so-called dialectical relationship of "extremes meet" is also reflected in the balanced relationship of nutritional needs. Violation of this balanced relationship will inevitably lead to element deficiency disease or antagonism. \x0d\\x0d\( 1) Nitrogen deficiency: Nitrogen is the main element that constitutes the organic protein of pitaya plants, and it is also an important component of nucleic acids, vitamins, alkaloids, enzymes and chlorophyll in organisms. Therefore, if the pitaya plant is short of nitrogen, it will grow poorly, the vines will be yellow and thin, the root system will be underdeveloped, the plant will grow slowly, or even stop growing, and the flower and fruit will drop, and the fruit quality will decline. However, nitrogen fertilizer should not be applied in a partial way, otherwise too much nitrogen will cause the vines to grow in vain without flowering and fruiting. \x0d\\x0d\(2) Phosphorus deficiency: When the pitaya plant is deficient in phosphorus, it will seriously affect the results. The quality of flower bud differentiation is poor, the fruit is small and the quality is poor. However, excessive phosphorus will also inhibit the absorption of nitrogen and potassium, and will also affect the absorption and transformation of other trace elements. \x0d\\x0d\(3) Potassium deficiency: Pitaya plants are short of potassium, which will lead to poor growth, decreased stress resistance, smaller fruits and poor quality. However, excess potassium will also affect the absorption of nitrogen, calcium and magnesium. \x0d\\x0d\(4) Calcium deficiency: Calcium deficiency in plants will affect the ability of pitaya to resist pests and diseases, and will also affect new growth points and root tips. However, too much calcium will reduce the nutritional solubility of trace elements such as boron, iron, manganese and zinc, and produce element deficiency disease, which will make the soil alkaline and harden, which is not conducive to the growth of pitaya plants. \x0d\\x0d\(5) Magnesium deficiency: the pitaya plant is magnesium deficient, the vines turn yellow, the fruit is small, the sweetness is poor, and the quality is degraded. At the same time, it will prevent the absorption of nitrogen and phosphorus. \x0d\\x0d\(6) Sulfur deficiency: Pitaya plants lack sulfur, which will affect assimilation. The vines are easy to wither, with poor stress resistance, small fruit and poor quality.
