Winter jujube naturally ripens in the solar calendar10-10, so it is named "winter jujube" because the weather in the north entered the cold earlier. Of course, generally early-maturing winter dates can be eaten in August and September, and can also be eaten in July;
At this time, winter jujubes are basically planted in greenhouse technology and artificially controlled. The taste and sweetness are very average, which is about 2 months earlier than the naturally mature winter jujube 1 and.
The price is also the highest. The initial purchase price was above 80 yuan per catty, which was slightly reduced in the later period. However, although this kind of jujube came into the market early, it tastes ordinary, expensive and unpalatable.
Normally mature winter jujubes are usually listed in June 10- 1 1. At this time, the winter jujube has sufficient sunshine, moderate moisture, high sweetness and rich jujube flavor.
Extended data:
Grafted winter jujube trees tend to have full branches, early flowering and early fruiting. However, winter jujube has a large amount of flowers and a low natural fruit setting rate. In order to promote fruit setting, it should be open at flowering stage. Under the same conditions, the opening time of winter jujube should be 2-3 days later than that of jujube.
Winter jujube grows vigorously, and the nail opening heals quickly after nail opening. Therefore, the nail opening should be wider than jujube 1-2 mm, and cut along the last nail opening 1 time 7-8 days after nail opening, reaching xylem, and the notch width is 1-2 mm, so as to ensure the complete healing of the nail opening;
It can also prolong the healing time to about 30 days. Healing too early, can not bear fruit, healing too late, often with high annual output, but not bearing fruit in the last two years.
