1. How much is the seed of Calligonum mongolicum?
The price of Hovenia dulcis Thunb seeds is about 25 ~ 1 kg in 40 yuan, but the price is different due to the difference of seed quality, variety, origin and market. Jujube trees are distributed in the Yellow River Basin and the Yangtze River Basin in China. Seeds are mainly used in production, and can also be propagated by layering and rooting. It usually takes five to six years to blossom and bear fruit. The flowering period is June, and the fruiting period is August to1October. Modern low-level branch technology can bear fruit 3 ~ 4 years in advance.
Second, the cultivation conditions of jujube trees
Jujube has a long history of cultivation and utilization in China. Tree height 10 meter, strong adaptability to the environment, drought tolerance, cold tolerance, barren tolerance, like sunshine. Most of the valleys, streams, roadsides or wet slopes below 65,438+0,000m above sea level are planted beside the courtyard and mixed with other evergreen and deciduous broad-leaved trees. If the soil is deep, fertile and moist, it can grow rapidly.
Third, how to breed the seeds of Calligonum mongolicum.
1. Seed collection: the seeds of Calligonum mongolicum 1 1 were collected when they matured in1October. The seed coat is reddish brown, one fruit contains three seeds, and the seed cortex is yellow and white, which is not easy to absorb water.
2. Seed germination: Calligonum mongolicum seeds germinate by wet sand layer stacking method, and the seeds are stacked layer by layer with wet sand, and the radicle expands after 50-60 days.
3. Sowing method: Calligonum mongolicum seeds can be sowed or drilled as required. Before sowing, the seedbed (small ridge) with a depth of 2~3 cm should be arranged, and the bed surface should be covered with straw and watered. The sowing amount per mu is about 10kg.
4. Seedling management: water and fertilize frequently at seedling stage to promote growth, grow 3-5 true leaf seedlings, keep strong and weak, and transplant when the seedlings grow to 70- 100 cm.
Fourth, the cultivation method of jujube
1. Select soil preparation: Jujube has strong adaptability, and likes a humid environment with abundant sunshine, fertile soil and good drainage, and its ph value is neutral. After land selection, dig a pit with a depth of 1 m, dig a fish scale pit on the slope to prevent soil erosion, and plant trees with litter in the pit.
2. Post-cultivation management: Calligonum mongolicum seedlings grow slowly, so young tree management should be strengthened. When weeds grow in spring and summer every year, loosen the soil to weed, water them in drought, and fertilize them three times in spring, March, summer, June, winter and November to promote growth.
3. Pruning: In the second year after planting, when the young tree grows to 1~ 1.5 meters, the main stem bends to form secondary branches, and the branches are spread in all directions in the same way, resulting in quick and fruitful results and increasing economic income.
4. Pest control: Calligonum mongolicum has strong vitality and good disease resistance, and leaf blight and aphids are common in seedling stage. Before and at the beginning of the disease, 1: 1:400 bordeaux solution was used to control leaf blight, and aphids were sprayed with 40% dimethoate 2000 times water solution.
5. Harvesting and processing: After the first frost in winter (1 1), the fruit stalks of Hovenia dulcis Thunb are picked several times when they are reddish brown, and the fruit branches are cut off and stored in the dark. After ripening for 7~ 10 days, it can be sold as fresh products or squeezed in the shade.
