1. The spring shoot fertilizer is generally applied after the spring shoots are drawn out in April, and is mainly composed of quick-acting phosphorus and nitrogen fertilizers, and the organic fertilizers are combined with chemical fertilizers. Using calcium superphosphate, peanut bran or soybean bran), manure and feces urine, 3 kinds of fertilizers are made into manure water according to the ratio of 2:3:100. The initial result tree uses 5 to 10 kilograms per plant, watering 1 times the loop or acupuncture, if adding a small amount of urea is better. 0.5 kg of compound fertilizer can also be applied.
2. Protect the fruit fertilizer from June to July, when the thumb of the fruit is large (starting to transfer pedicle). Use calcium superphosphate, peanut bran, and human feces in a ratio of 1:2:100. Use 15 to 20 kilograms of water for each plant. 0.5 kg of compound fertilizer per plant can also be used.
3, strong fruit to promote flowering from the beginning of August, the fruit shape, full, and a group of flowers continue to open, then you can apply a second fertilizer, the same type and quantity of fruit fertilizer. At this time, the temperature is high and the sunshine is strong. Fertilization should be carried out in the evening. If the drought is watering or watering.
4, to promote cooked fertilizer In order to make the fruit early maturity and improve quality, 20 days before each fruit production will be ripe to apply a quick-release compound fertilizer, 50 grams per plant, and appropriate to reduce irrigation.
5, wintering fertilizer (basal fertilizer)
This is the key fertilizer in the year and should account for more than 25% of the annual fertilization amount. It plays an important role in enhancing tree vigor, improving cold resistance, reducing winter defoliation, and increasing the output in the coming year. In December, heavy fertilizer was applied, mainly organic fertilizer, and 15-20 kg of composted livestock manure per plant, 1.5 kg of bran fertilizer, and 1-1.5 kg of superphosphate. Later, as the age of trees increases and the amount of results increases, the amount of basal fertilizer is appropriately increased. The carambola entering the production period, after 6 months of each year, vegetative growth and reproductive growth are carried out at the same time. The shoots, buds, flowering, and the result are collected in one tree. The amount of fertilizer required is large. Therefore, it is necessary to apply fertilizer continuously from June to October. Apply 15 times a day. 80% of the fertilizer should be applied at this time, mainly organic fertilizer, and fertilizers should be properly used. The amount of fertilizer applied to the tree increased with increasing yield. Generally, for every 50 kg of fruit produced, 1 kg of peanut bran was applied, and 0.5 kg of urea, potassium chloride, superphosphate, and lime were added, and 50 kg of soil-based fertilizer was added to the rhizosphere. . The method of fertilization is the same as other fruit trees. The juvenile tree adopts circular or strip fertilization. Big trees are strips, spots or fertilizing. Cover soil after fertilization. When the soil is too wet, it is not suitable to apply water fertilizer, so as to avoid causing rot. Fertilizer should also pay attention to, fertilizer should be used in conjunction with organic fertilizer, but also depending on tree vigor, leaf color, soil fertility and other factors determine the time, frequency, type of fertilizer and fertilizer. Before and after the flowering period, partial nitrogenous fertilizer should be avoided so as to avoid excess nutrients, which is not conducive to flowering results, and may also incur pests and diseases. In addition, timely top-dressing, top and post-blooming with 0.3% potassium dihydrogen phosphate plus 0.1% boric acid spray 2 to 3 times, can improve the fruit setting rate and quality.
