As an important fruit tree crop, the flower bud differentiation process of citrus has a crucial impact on the subsequent flowering and fruiting. Knowing when citrus flower buds are differentiating and fertilizing them properly is key to ensuring healthy citrus growth and yields. This articleHaifu AgricultureThe timing of citrus flower bud differentiation and the corresponding fertilization guidelines will be given in detail.
1. Citrus flower bud differentiation time.
Citrus flower bud differentiation occurs mainly between late autumn and early spring, depending on the variety and local climatic conditions. In general, when the temperature gradually drops and the daylight hours shorten, the citrus tree begins to enter the flower bud differentiation stage. At this stage, the number and quality of flower buds are determined by the internal nutritional status and external environmental conditions.
2. Guide to fertilization of flower bud differentiation.
Fertilization principle: In the flower bud differentiation stage, fertilization should follow the principle of "phosphorus and potassium fertilizer as the mainstay, supplemented by nitrogen fertilizer". Phosphorus and potassium fertilizers can help promote flower bud differentiation and improve flower bud quality, while appropriate nitrogen fertilizers can help maintain the normal growth of the tree.
Fertilization time: The fertilization time should be selected about one month before the flower bud differentiation, which can ensure that the fertilizer can fully play its role in the flower bud differentiation process.
Fertilizer type and dosage:
Phosphate fertilizer: You can choose diammonium phosphate, superphosphate and other phosphate fertilizers, and the dosage per mu is about 10-15 kg.
Potash fertilizer: You can choose potassium chloride, potassium sulfate and other potassium fertilizers, and the dosage per mu is about 15-20 kg.
Nitrogen fertilizer: Nitrogen fertilizer such as urea and ammonium sulfate can be selected, but the dosage should be controlled within 5 kg per mu, so as not to cause excessive growth of the tree body and affect the differentiation of flower buds.
Fertilization method: Fertilizer can be applied in furrows or holes, and the fertilizer can be evenly applied into the soil and fully mixed with the soil. At the same time, attention should be paid to watering to promote the dissolution and absorption of fertilizers.
3. Summary. Flower bud differentiation is an important stage in the growth process of citrus, and reasonable fertilization is of great significance to improve the quality and quantity of flower buds. Growers should follow the above fertilization guidelines according to the growth of citrus and local climatic conditions to ensure that citrus trees can grow healthily, blossom and bear fruit. At the same time, with the continuous progress of agricultural science and technology, citrus fertilization technology will also continue to improve and innovate, bringing more convenience and benefits to growers.
