Green jujube planting technique
1. Garden selection
Green jujube has strong adaptability and low requirements on soil, but it has high requirements on fertilizer, sunlight and water source. It needs to be planted in paddy fields, flat slopes or terraced fields with sufficient sunshine and convenient irrigation. In areas where light is poor, drought, typhoon is more, water is scarce, etc., its yield and quality will be affected to varying degrees.
2, variety selection
There are relatively many varieties of jujube, and the yield, quality, fruit shape and flavor of different jujubes are quite different. There are mainly Huangguan, Hongyun, Wuqian and other varieties. It is possible to select excellent varieties from the actual conditions of the orchard. Planting, but need to pay attention to 2% pollination tree when planting, improve the fruit set rate of jujube.
3, rational planting
The planting season of jujube is best in March to May, when the temperature is not high, the climate is humid, and there is much rain. It began to bloom in August and matured in November. If the management science is in place, the yield of each jujube can be 10 kg, which can be put into production in the same year and harvested in the same year.
4, fertilizer management
The jujube has a large proportion of base fertilizer and can account for 50% of the total fertilization in the whole year. When the newly planted fruit tree base fertilizer is used for acupuncture, the fermented livestock and poultry fertilizer is at 15 kg/point, the phosphate fertilizer and the gluten fertilizer are respectively 0.5 kg, 1 kg/hole, and all the base fertilizer and soil are mixed well before backfilling. After all the organic fertilizers are backfilled, the topsoil is filled back and 20 cm from the ground is taken to avoid water accumulation in the rain.
5, pruning and protecting fruit
The jujube branching should be mainly laterally oblique, with a large canopy area and relatively many branches. It is necessary to carry out scientific pruning to form a good tree shape, which is convenient for ventilation and lighting, effectively reducing pests and diseases, and improving the yield and quality of jujube. When it is dry, ensure that the old trunk can promote early flowering and maturity of green dates.
6. Pest control and harvesting
The jujube has relatively few pests and diseases, mainly beetles, fruit flies, etc. If the scales need to be quickly used to cull, the fruit flies can be culled using trichlorfon. Spraying pesticides should be stopped 20 days before fruit harvesting.
Green jujube matures in a few months (time to market)
The jujube is listed in the mature season from November of each year to March of the second year, just in time for the harvest period from New Year's Day to the Spring Festival. People who like to eat dates may wish to buy some fresh jujubes at this time to come back to eat. Will be disappointed. However, although jujube is delicious, it can not eat much, because eating a lot of green dates will affect the stomach and intestines. The outer skin of jujube is relatively hard and not so easy to digest.
