First, nursery technology:
1. Seed-picking: In the middle and early August, when the fruit of Xanthoceras sorbifolia begins to crack, it can be planted. Remove debris, dry, peel, dry, and place in a moisture-proof container.
2. Germination: In the first half of April of the following year, the rapid germination method was used for germination. The seeds were immersed in warm water of 45[deg.] C. for 7 days before sowing, and allowed to cool naturally. After 3 days, remove and load the basket and cover the straw. Put it in the greenhouse at 20 to 25°C twice a day to maintain the humidity, and then gradually split the mouth in the middle and late stages to orderly sow.
3, sowing: in the entire good rake ditch deep 3 ~ 4 cm, spacing 15 ~ 20 cm, on demand,
Umbilical flat, covered with nutrient soil (1 part soil mixed fertilizer 2 soil mixed) 2 ~ 3 cm, compaction, gently leveled.
4. Management: Pay attention to irrigation or drainage after emergence. Prevent excessive humidity, cause rot, avoid overdrying, and affect sprouting. From June to July, nitrogen fertilizers were applied once every month, liquid compound fertilizer was sprayed once a month, and soil was sterilized in time. Generally, seedlings can be planted in the same year, or they can be cultivated for 1 to 2 years to become large seedlings, and they can also be rooted for nursery.
5. Grafting: In order to change the thoroughbred, early results need to be grafted. Rootstocks used more than 1 cm seedlings, scion collection in March, buried with wet sand, in late April when the seedling layer skin off bone when grafted with xylem bud grafting method, 10 to 20 cm above the ground. After half a month, the buds germinate, and the tip of the anvil is cut about 0.5 cm above the shoot (cutting the mouth to the back of the bud). When the budding is about 15 cm long, the seedlings should be tied in a windy area to prevent windbreaks, and the roots should be removed in time.
Second, planting technology: strong adaptability of fruit. There are various planting methods. When constructing a garden, loose, fertile, well-drained sandy loam soil should be used. Plant spacing 22 or 23, 33, 34 or appropriate increase. The mountains can be denser and the fertile plains of the plains can be thinner. After the spring ice planted with mud, the roots should be stretched, the shallow planting should be practical, and the water should be poured. After the water penetrated, the soil should be kept at the base to protect the trees. Normally, nitrogen fertilizer is applied before germination, followed by phosphorus and potassium fertilizers in June, and once after autumn. Watering should be combined with fertilization. Generally, it is not necessary to water more to prevent rot.

The fruit was planted once in one year, yielded for many years, and the results began three years after planting. Eight years into the fruit period, the fruit period is more than a hundred years, so it is an important woody oil plant in North China. The masses said that the cranberry tree is a hard-boned fuel tree species that cannot be destroyed or destroyed.
