Problems solved by technology

At present, the cultivation technology of jujube trees in my country mainly adopts the open-field cultivation method of once a year. Due to the centralized market during the harvest period, the sales and price of jujube fruits are limited, which has a negative impact on the development of the jujube industry.
Although many fresh jujube storage and preservation techniques have appeared in recent years, the sales period of fresh jujube can be extended for several months, but long-term preservation will inevitably cause the taste of fresh jujube to deteriorate and the nutritional content to dec

Example Embodiment

[0006] Example 1

[0007] Using the winter-warm greenhouse to promote the double-cropping of jujube trees a year, the planting varieties are selected according to the ratio of pear jujube tree: winter jujube tree=8:2, and the planting density is 3 meters in row spacing and 2 meters in plant spacing. The temperature in the shed has gradually increased since December 11, and the daytime temperature in the shed should be controlled at 18-19°C during the day from 1-10 days after the temperature rise, and the temperature in the shed should not be lower than 5°C during the day. Control at 20-22℃, the night temperature is not lower than 7℃, on the 21st-30th day, the daytime temperature in the shed is controlled at 23-25℃, the night temperature is not lower than 9℃, from the 31st day to before flowering, inside the shed The temperature in the daytime is controlled at 25-28℃, and the temperature at night is not lower than 10℃. The relative humidity in the shed during the above period is ma...

[0008] Example 2

[0009] The method of the present invention using the winter-warm greenhouse to promote the double-cropping of jujube in a year is described in more detail as follows:

[0010] 1. Variety selection and planting: Lizao (self-flowering and fruiting) as the main planting variety, and Dongzao as the pollination variety. The ratio of main planted varieties to pollinated varieties is 8:2. The planting density is 3 meters in row spacing and 2 meters in plant spacing. Before planting, dig a 60 cm deep and 80 cm wide planting ditch in the north-south direction, and separate the topsoil and subsoil. When backfilling, every 666.7m 2 Apply 4,000 kg of organic fertilizer such as decomposed chicken manure, mix the organic fertilizer with the soil evenly, and fill it into the bottom of the ditch. When it is 30 cm from the ground, only fill the mature soil to prevent the fertilizer from burning the roots, and then pour it thoroughly.

Abstract

A method for promoting the jujube tree to bear the jujubes twice in one year by use of the big plastic film shed warming the in winter and regulating temp and humidity includes such steps as removing the plastic film after the first batch of jujubes is picked up in order to update the tree, promoting second blossom and fruit bearing, covering film in the last 10 days of the October, picking up the second batch of jujubes, pruning, covering film in the day and removing film at night for forcing the dormancy of jujube tree, and warming from the middle 10 days of the December.

Description

technical field [0001] The invention relates to a method for cultivating fruit trees, in particular to a method for promoting double cropping of jujube trees in a year by using a warm-winter greenhouse. Background technique [0002] With the continuous improvement of jujube varieties in my country, the taste and nutritional value of fresh jujube fruits are constantly improving, and the planting area of ​​jujube trees is also expanding year by year. At present, the cultivation technology of jujube trees in my country mainly adopts the open-field cultivation method of once a year. Due to the centralized market during the harvest period, the sales and price of jujube fruits are limited, which has a negative impact on the development of the jujube industry. Although many fresh jujube storage and preservation techniques have appeared in recent years, the sales period of fresh jujube can be extended for several months, but long-term preservation will inevitably cause the taste of ...
