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 decrease, which will affect the edible value of jujube.
Chinese invention patents with patent numbers ZL02135663.7 and ZL03111956.5 respectively disclose a method for promoting delayed ripening of winter jujube and a method for promoting early ripening of winter jujube, which can make winter jujube ripen in advance or delay ripening for more than 30 days, thereby avoiding the However, the above-mentioned two technologies still adopt the cultivation method of once a year. Although the economic benefits can be improved through off-season cultivation, they cannot greatly increase the yield per mu.

Embodiment 1

[0007] Utilize the winter warm type greenhouse to promote the method of jujube two crops a year, select the planting species according to the ratio of pear jujube tree: winter jujube tree = 8:2, and the planting density is 3 meters between rows and 2 meters between plants. From December 11th, the temperature in the shed gradually increased. On the first 10 days after the start of the temperature rise, the daytime temperature in the shed was controlled at 18-19°C, and the nighttime temperature was not lower than 5°C. On the 11th-20th day, the daytime temperature in the shed was Control at 20-22°C, and the nighttime temperature is not lower than 7°C. On the 21st-30th day, the daytime temperature in the shed is controlled at 23-25°C, and the nighttime temperature is not lower than 9°C. From the 31st day to before flowering, in the shed The daytime temperature is controlled at 25-28°C, and the nighttime temperature is not lower than 10°C. The relative humidity in the shed is kept a...

Embodiment 2

[0009] The method that the present invention utilizes winter warm type greenhouse to promote jujube tree to ripen twice a year is described in more detail as follows:

[0010] 1. Variety selection and planting: the main planting variety is Lizao (self-fertilizing), and the pollinating variety is Dongzao. The ratio of main planting varieties to pollinating varieties is 8:2. The planting density is 3 meters between rows and 2 meters between plants. Before planting, dig a planting ditch with a depth of 60 cm and a width of 80 cm according to the north-south direction, and divide 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 and soil evenly, and fill it into the bottom of the ditch. When it is 30 cm above the ground, only fill it with cooked soil to prevent the fertilizer from burning the roots, and then water 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 ...
