1, bottom fertilizer more organic fertilizer, dragon fruit on the soil requirements are not strict, can adapt to a variety of soils, but in the weak acidic soil or neutral soil, the growth will be better. Dragon fruit to grow better, the most important thing is, to plant dragon fruit in loose and fertile, rich in organic matter in the soil, in such a soil into the fully rotted farmyard manure, a variety of animal manure, a variety of cake fertilizer, organic microbial fertilizer. In 1 ~ 2 months before planting, digging a good planting hole in advance, in each planting hole side to add about 8 kg of high-quality organic fertilizer + 0.5 kg of high-nitrogen composite fertilizer, soybean cake 0.5 kg, beneficial microbial fungi fertilizer kilograms, with the soil mixed well, to provide sufficient nutrients for the growth of dragon fruit. Generally in March July October each year, each applied into a farmyard manure as a bottom fertilizer.
2, fertilizer, dragon fruit flowering and fruiting time is long, as long as the temperature is suitable, the year can be many times flowering and fruiting, flowering and fruiting period of about 6 months, generally every month to carry out a fertilizer, dragon fruit root system is relatively shallow, the middle of the fertilizer is appropriate to use the flush, combined with the whole plant spraying way to carry out. Fertilizer available amino acid water-soluble fertilizer, potassium dihydrogen phosphate, as well as containing boron, magnesium and other trace elements in a variety of fertilizer, when the formation of young fruits, continue to spray containing boron, magnesium elements of trace elements of foliar fertilizer + 0.2% potassium dihydrogen phosphate aqueous solution + Tenda 2116, so as to improve the quality of the fruit.
The first 12 months of dragon fruit planting, nutrient growth is mainly in the fertilization on the bias of a little nitrogen fertilizer, phosphorus and potassium fertilizer is appropriate to less, one year later, into the fruit period, reduce the amount of nitrogen fertilizer, increase the amount of phosphorus and potassium fertilizers, to promote the growth of dragon fruit robust, more results.
3, frame to prevent collapse, dragon fruit root system is shallow, upward climbing growth, do not take the frame, in the fruit period is easy to fold, generally use 1.8 meters high cement columns as a frame, the above ground part of the left 1.4 meters or so, buried in the soil 40 centimeters or so, it is not appropriate to use wood frame, because wood is easy to rot in the soil for a long time, the production of the delay in the matter.
4, before and after the Ching Ming Festival for planting, dragon fruit can withstand low temperatures of zero degrees, but also can tolerate high temperatures of 40 degrees, before and after the Ching Ming Festival, the soil temperature stabilized at more than 15 degrees can be planted, generally set the seedling depth of about 5 centimeters or so, and then pouring the root of the water, the water seeps, covered with straw to maintain moisture. Dragon fruit planted a year before the beginning of flowering and fruit, the second year can be a small number of results, the third year can enter the fruiting season, do not need to be planted every year, every year should be carried out to remove the fruiting branches, to promote the re-sprouting, to achieve the year's yield.
