breeding method
There are branches, roots and seeds. In ramet propagation, seedlings germinated from the roots of mother plants can be transplanted. Rooting propagation refers to digging up the roots before the adventitious buds on the roots are unearthed in early spring, cutting them off according to the length of 10- 15 cm, obliquely inserting them or burying them shallowly to keep the soil moist and conducive to survival. Seed propagation is carried out from May to June every year. Mature fruits are collected, washed and stored in wet sand until autumn or the next spring, and can be transplanted after one year of sowing. The most practical method is to dig new branches and plant them after all the leaves have fallen off in June and February of 5438.
2. Soil preparation and transplanting
Choose a slightly acidic gentle slope with deep soil layer, rich and loose soil layer and good drainage, and dig deep into the soil. Transplanting according to the spacing of 50 cm× 100 cm or 100 cm× 100 cm.
Three. Tiantuan management
Apply sufficient base fertilizer before transplanting, and apply 3-5kg farmyard manure to each plant. In the growing period, combine loosening soil and weeding, and topdressing 2-3 times a year, with nitrogen fertilizer as the main fertilizer and appropriate amount of phosphorus and potassium fertilizer. Apply seedling fertilizer in March, flower fertilizer in April, and overwintering fertilizer 5438+065438+ 10 in June. Apply human excrement and urine per mu 1500-2000 kg. Pay attention to watering when it is dry in summer and autumn. From April to May, when new branches have lateral branches, the terminal buds are removed to promote the growth of lateral branches, and at the same time, the nuclear lateral branches are removed to promote the secondary lateral branches, so that the leafy branches are flourishing, thereby increasing the fruiting mother branches in the second year and increasing the yield. A post should be erected next to each plant in the fruiting period to prevent lodging. In the first half of May, when the fruit is eight-ripe, it will be harvested and packaged together with the calyx.
