Dongzao is a kind of fruit belonging to the plum family. It usually matures in October, so it is called Dongzao. Winter jujube contains a lot of vitamin C, which is the most among all fruits, even the vitamin C hawthorn can't compare with it. Although the winter jujube matures in October, it has very high requirements for the growth environment. Today, the editor will come to talk to you about the environmental requirements for planting winter jujube.
First: temperature
The growth and development of all fruits are inseparable from a reasonable temperature, and the same is true for winter jujube. The temperature directly determines the planting range of winter jujube. Winter jujube is a kind of fruit that likes warmth. Although it matures in winter, sowing is carried out in spring. The temperature is very high when it grows. Winter jujube germinates relatively late, but leaves fall very early. After sowing in spring, as long as the temperature reaches 14 degrees, the seeds can germinate normally. The temperature reaches 17 degrees and shoots and shoots. When it reaches 20 degrees, flower buds will form, and flowers will bloom at 25 degrees. Winter jujube has a strong ability to adapt to temperature. Whether it is a low temperature of 30 degrees in winter or a high temperature of 45 degrees in summer, it can grow normally.
Second: Humidity
Winter jujube is also very resistant to droughts and floods, and can grow normally in areas with heavy rainfall. Even if the area of water in the orchard is one month, the fruit trees will not be flooded. However, winter jujube requires different humidity in each growth stage. For example, a lot of water is needed for pollination and fertilization during the flowering period, and the humidity should be kept at about 70%. If the humidity does not exceed 40% during this period, it will hinder the pollination and fertilization of pollen, which will cause the phenomenon of flower and fruit drop; if it encounters rainy weather for several days during the flowering period, the pollen will not bud, thus reducing the fruit setting. The success rate.
Third: light
Light is an important condition to maintain the growth of Dongzao. Dongzao has a strong light-loving property. The amount of photosynthesis of the jujube tree is greatly related to the light intensity and time absorbed by the fruit tree. Adequate light duration can promote cell differentiation, control cell division, and have great benefits for nutrient accumulation and growth of winter jujube. The probability of fruit setting is also closely related to the duration of the light. Short light time will not only reduce the possibility of fruit setting, but also hinder the growth and development of the root system. The restricted growth of fruit trees cannot increase sufficient water and nutrients for fruit development.
Fourth: Soil
Soil is an important medium for jujube trees to absorb water and nutrients. Soil fertility, permeability, pH, etc. will affect the growth and development of fruit trees. Although fruit trees do not require much soil, they can grow in high acid-base or poor soils. However, when planted in fertile soil, winter jujube trees can grow taller and their roots will extend wider. The yield of winter jujube is only It will be higher and the taste will be better. If it is planted in very poor, viscous, poorly water-retaining soil, or poorly permeable soil, the fruit trees will develop slowly, the fruit will be small, and the yield and taste will not be good.
Winter jujube matures in winter, but the planting environment is not suitable. It is naturally impossible to have high yield. This is because it takes nearly a year from sowing to harvesting. This will start planting in spring. Well, the requirements for the planting environment of winter jujube are introduced here first. Maybe you are not very clear. You can pay attention to the editor first, and the editor will slowly explain the planting knowledge of winter jujube to you.
