Taiwan jujube fruit is large, fine in core, crisp in meat, sweet in taste and high in nutritional value; and the fruit is hung in the year of planting in the same year, and the harvest period can enter the second year. Taiwan jujube grows roughly and fast, has strong adaptability to temperature, can withstand high temperature of 35 degrees and a low temperature of 10 degrees, and is suitable for planting in tropical and subtropical areas. So how can growing Taiwanese jujubes yield high yields?
At present, the varieties cultivated in Taiwan jujube mainly include: GaoLang No. 1 (also known as Fifty Sons or Red Cloud), Five Thousand, Biyun, Yellow Crown, Five Crown, Telong, Century Jujube and so on. Different varieties, their yield, fruit shape, quality, flavor, etc. are quite different. Such as the yellow crown variety, the largest fruit shape, the single fruit weighs up to 150 grams, shaped like an apple, but the sugar content is low, only 11 degrees, the taste is lighter, the meat quality is also looser; the single fruit of the red cloud variety weighs about 50 grams, the egg shape, the sugar degree reaches 14 degrees, the quality flavor is good, and the price is also higher; five thousand varieties are the most popular varieties among many varieties, the fruit is oval, the single fruit weighs 80 to 100 grams, the ripe fruit is light green, the sugar degree is 13 to 15 degrees, the flesh is white, the texture is crisp, the sweetness is fragrant. Commodity fruits sell for the highest price.
Taiwan jujube to 3-5 months planting is the most ideal, this period of temperature is not very high, rain more, humid air, even if the planting of root seedlings, the survival rate is as high as 95%, the growth rate is also very fast, August began to flower, November began to ripen, proper management, the year of a single plant fruit production up to about 10 kg, can achieve the purpose of planting that year, the year of production, the purpose of the year of income. If it is a bagged seedling, it can be planted all year round, and the survival rate can generally reach more than 95%. High-quality bagged seedlings are planted even in July and August, and can still flower and bear fruit that year. Root seedlings are planted in the summer high temperature season, if the root seedlings are not well packaged, and they are transported for a long time, and the interval is long, the survival rate cannot be guaranteed.
Taiwan jujube branches are mainly lateral oblique growth, the canopy area is large, there are many branches, and reasonable pruning can form a good tree shape, which is convenient for ventilation and lighting, reducing pests and diseases, and improving yield and quality. There are fewer pests and diseases of jujube in Taiwan, and the main pests and diseases are: powdery mildew, shell worms, caterpillars, fruit flies, etc. When the climate is dry, powdery mildew is more likely to occur, the spread is also faster, the young fruit, leaves are more harmful, can be controlled by fungicides such as powder rust Ning; spray once in the whole park at the beginning of the disease, and spray once every 7 days after that, a total of 2 to 3 times. Mesophores can be killed by rapid culling, oxidation of lego, and killing of scavengers; caterpillars and fruit flies can be sprayed with dichlorvos and pyrethroids. Spraying should be stopped 10 days before the fruit ripens. Spraying is best done in the morning or in the evening.
