The papaya crabapple I bred was bred with the excellent variety of Yizhou papaya begonia as the female parent and the compound flower variety of papaya begonia as the male parent. Pay attention to love wood bonsai and play with love wood bonsai.

In the decades of cultivation and production of papaya Begonia, we have seen that the true papaya begonia has early, large and many fruits, and its ornamental fruit and medicinal value are extremely high, but its flowering is single-petal, rarely double-petal, and the value of flowering is low. How to turn a single flower into a compound flower, which can be used for greening and potted plants, so as to improve its viewing value? At first, I used single-crossing technique to do parent-to-parent hybridization. Five years later, a single plant with multiple flowers was found and there was hope. Conscientiously sum up experience: the speed of single crossing is too slow, male removal and bagging are too troublesome, and a large number of varieties will not be bred in more than ten years, how to speed up the speed? I think of natural breeding. Because honeybee pollination can also cultivate new varieties, it is decided to use the method of group crossing.

The male parent pollen was crossed with hundreds of different varieties of papaya and begonia for many times, and the seeds were taken and sown after autumn. After 5 years, more than 100 varieties of compound flowers were found successively, single planting was dug out in time, the growth and characters were observed, and the breeding objectives were those with fast growth, no thorns or less thorns, compound flowers, large and colorful flowers and long flowering time.

After 20 years, more than 30 varieties of ink red, brilliant red, pink and green flowers were selected, with strange and bright colors, growing like papaya and begonia, with high ornamental and greening value. Pay attention to love wood bonsai and play with love wood bonsai.

Outstanding features of ■

The management of fast-growing grafted seedlings was strengthened, and the annual growth was about 0.8 cm in ground diameter and 80cm in height. It has been planted for 4 years, the ground diameter is about 3.5 to 4.5 cm, and for 6 years, some ground diameter can reach 6 cm, the plant height is 3.5 meters, and the crown width is more than 3 meters, which is suitable for planting in courtyards, parks and large-scale gardens.

Part of it can bear fruit, the weight of small fruit is more than 150g, the weight of big fruit is more than 1000 grams, and the yield per mu is more than 10,000 jin. Green flowers, potted flowers, the construction of scenic spots, the combination of ecological and economic benefits, there are broad prospects for development.

It can be cultivated in the open field where the altitude is 5-1700m, the rainfall is 600mm-1600mm, the soil pH value is 6.5-7.5 and the temperature is-20-40 ℃.

Key points of ■ cultivation

Cultivation time: the Autumn Equinox to the Spring Equinox is the suitable planting period, it is better to be planted in the south of Shandong, Henan and Shaanxi before the year, and must be finished before the Spring Equinox after the year. In the cold areas of the north, it can be planted with buds from the Spring Equinox to Qingming after the soil is thawed. Pay attention to the fast transportation and planting speed. When planting, dig a deep pit of 30 × 30 cm, put the flower seedlings into the hole, fill the soil with 2 + 3, lift the seedlings and soothe the roots, then compact them, pour a bucket of water, and then fill the soil. If there are conditions, it can be ridged, covered with plastic film, kept at a constant temperature and preserved soil moisture, so that the roots are in the soil and bear fruit under Xuan, which is conducive to the development of seedlings.

Planting density: the row spacing is 2 × 1.5 meters, 220 plants per mu. The young trees were cultivated for the second time, with a row spacing of 1.5 × 1 m and more than 400 trees per mu. If bonsai seedlings are raised, it can reach 1200 plants per mu. Note that when the density is high, interlaced and interplant transplants are sold in time.

Management: fertilizing 3 times a year. Pre-flowering fertilizer: from June to July, flowering fertilizer was applied in the peak growing season and after autumn. 20 days before flowering, 50 jin of compound fertilizer and 15 jin of urea per mu are beneficial to more and larger flowering. Topdressing increases growth during the growing period. The application of base fertilizer in autumn lays a good foundation for flowering in the second year.

Watering: watering in case of drought, drainage in case of waterlogging, no watering in flowering season. Such as watering, the leaves absorb nutrients first and grow vigorously, affecting the flowering effect of the first flowers and then the leaves.
