Taiwan Province Daqingzao has the characteristics of fast growth, early maturity and high and stable yield. Economic life is over 30 years. 45-66 grafted seedlings per mu can blossom and bear fruit in the same year. Fresh dates can be harvested after 9 months of planting, with an yield of 500-700 kg per mu and 800- 1500 kg in the following year. In the fourth year, it can enter the high-yield period, with an yield of 4500-6000 kg per mu. In fruit tree planting, Daqing in Taiwan Province Province has long been a short, flat and fast project worth popularizing. In areas where the temperature is below zero in winter, greenhouses must be planted. The fruit of Daqingzao is rich in nutrition. The ancients said that "three dates are pale and live forever".

High-yield cultivation techniques of Daqingzao in Taiwan Province: Daqingzao, also known as Indian jujube and Maoyezao. Originally from India, it was introduced to Taiwan Province Province, China, and became an economically cultivated fruit tree through variety selection. In recent years, it was introduced to the mainland from Taiwan Province Province, and the upsurge of planting big green jujube was formed in southern China. Daqingzao is fast-growing and easy to cultivate, and can bear fruit in the same year. The close planting garden can achieve high yield in the second year, and the yield per mu can reach 2000-3000 kg.
Jujube in Taiwan Province Province is ripe in winter, and the harvest period is as long as 3-4 months, which avoids competition with other fruits and is convenient for storage and transportation. It can be kept fresh for more than 10 days at normal temperature and for more than 30 days at low temperature, and can be easily transported to all parts of the country for sale. 1. Growth and fruiting characteristics: Daqingzao grows all year round. Young trees branch 3-4 times a year. The flower bud differentiation of Daqing jujube is rapid, continuous and lasts for a long time. The same plant has a large number of flowers, flowers and fruits, and it blooms and bears fruit twice a year. Flower bud differentiation is synchronized with the growth of new buds. The flower bud differentiation period is May to August, and the flowering period is 2 to 3 months. March-May is spring every year, fruit ripens in August-September, and blooms in autumn of 8- 10, and February-March of the following year.
Requirements for environmental conditions: Daqing jujube can grow normally in areas where the average temperature is higher than 17.5℃ and there is basically no frost all the year round. The daily average temperature reached 65438 08℃, with more buds sprouting and rapid growth of new shoots. When the daily average temperature is lower than 15℃, the buds rarely germinate and sprout. When the temperature is lower than 18℃, the flowers bloom later. Therefore, Daqing jujube is frosty in winter and cold in early spring in some parts of the south, and it still needs to be cultivated in winter through anti-freezing measures or facilities (greenhouses) to ensure the safe overwintering of flowers and fruits in autumn. Daqingzao is drought-tolerant and can be planted in dry-hot valley with annual rainfall of 700-2400 ml. However, in the dry season from March to April, irrigation should be done twice a month to promote the flowering of branches. Daqingzao is a kind of tree species that actively likes light. Under the condition of sufficient light, it has fast growth, large flowers and high fruit setting rate. On the contrary, the fruit setting rate is low and the flower and fruit drop are serious. Therefore, pruning should be done in production to make the branches sparse. Daqingzao has strong adaptability to soil and can grow on sandy soil, gravel soil, clay and loam. The PH value is 6.0-7.5. When planted on loose sandy soil and sandy loam, the fruit quality is better. Daqing jujube grows vigorously and its yield is stable on loam with deep soil layer and fertile soil.
