Jujube trees need to be poured with water for a year, depending on the weather. In a year of weathering, it may not be poured or poured. If it hits a dry year, it will require more water. In the course of a year's growth, the jujube tree generally needs to be poured with four waters in case of drought and rain. which is:
First, flowering water jujube flowering and setting fruit not only need a certain temperature, but also need a certain humidity, flowering watering can make flower buds increase, prolong the flowering period, promote the fertilization organs elongation and pollen grain germination. At the flowering stage, flower bud differentiation, flowering and fruit setting, and long branch leaf development are the most concentrated requirements for nutrients in the growth process of jujube trees in a year. Therefore, in case of dry weather, the flowering season must be timely watered to prevent high temperatures. The drought caused a defocused flower phenomenon.
Second, the first time the first water should be combined with the jujube first flush fertilizer at the same time as well, the watering time should be implemented before the physiological fruiting period is good, this time not only watering can quickly enlarge the fruit, It can also play a very important role in reducing physiological fruit loss and sunburn prevention.
Third, the second time the watering of the expansion water should also be combined with the second time of the jujube topdressing at the same time as well, the watering time should be carried out during the ripening period of the jujube fruit, at this time the watering can expand the fruit for the last time, improve The yield increases the sugar content of the fruit, and at the same time it is of great benefit to the fruit surface, quality, and prevention of sunburn.
Fourth, coloring water jujube fruit coloring period watering, not only can reduce the phenomenon of jujube fruit wrinkle crust, but also reduce the phenomenon of Yu Yu crack fruit, the jujube fruit taste, quality, storage, transportation, sales, etc. are certain Impact.
In addition, jujube trees generally need to be applied four times in the growth of a year. which is:
First, basal fertilizer is also called base fertilizer, and basal fertilizer is usually implemented after harvesting of jujube or before germination in the following year. On the whole, jujube harvesting is implemented as good, because at this time, the temperature is still high, and the photosynthetic and root absorption functions of the leaves are also strong. The tree can absorb and store large amounts of nutrients and play a role in flowering, fruit setting and high productivity in the coming year. A certain role.
Second, foliar fertilizer foliar fertilizer refers to foliar spray fertilizer, foliar spray fertilizer mainly amino acids, amino acids because of calcium, boron, zinc, iron and other necessary date elements of jujube, jujube fruit The anthracnose, sunburn, and yellow leaves of the jujube tree all have certain curative effects, and can increase the sugar content of the fruit and the thickness of the skin, which facilitates storage and transportation. It is recommended to spray and pest control, and spray fertilizer can be sprayed at the same time each time, no need to spray.
The first time the top dressing date has two expansion periods, the first top dressing should be performed during the first expansion of the date fruit, that is, before the physiological fruit drop period. At this time, the top dressing is mainly nitrogen fertilizer because nitrogen fertilizer can Rapid expansion of fruit, increased yield, and can also play a role in reducing the physiological fruit drop.
Fourth, the second top-dressing The second top-dressing should be in the second fruiting period of jujube fruit, that is, jujube fruit has just been ripened. This time, top-dressing is mainly potash, because potassium can increase the fruit's sugar content and increase fruit. The brightness of the surface can enable the fruit to be listed early in advance.
