Sakyamuni is also called annona.

Growth habit

Like light, like warm and humid climate, the annual average temperature is required to be above 22 degrees, not cold-resistant; Suitable for deep fertile sandy loam with good drainage.

1, seedling propagation

The propagation methods of annona include seed propagation and grafting propagation. Common annona seedlings have the characteristics of early fruiting and high yield, but their characters are not easy to maintain and are prone to premature aging. At present, AP annona is widely used as seedling stock, but it is prone to root rot in production. Several rootstocks resistant to root rot have been found in Zhanjiang South Asia Hot Cropping Research Institute, but intermediate rootstocks are needed. After the rootstock is selected, the first task is to cultivate strong seedlings and make them reach the grafting standard quickly. Using common annona as rootstock, the seeds should come from high-yield and high-quality mother plants of excellent varieties. The fruits with large fruits and correct shapes should be washed after being taken out, and the seeds without solid grains and small grains should be immediately removed, dried and sown. The seeds sown in the next spring should be fully dried and sealed. When the rootstock thickness reaches about 1 cm, grafting is carried out. The grafting method depends on the season, and the phloem is not easy to fall off in spring, so branch grafting is generally used, and bud grafting is generally used in summer and autumn. When annona is grafted by bud grafting, it usually takes 20-30 days to untie, while when it is grafted by branch grafting, the bud is usually picked first and then unbound. For the plants survived by bud grafting, the rootstock can be cut off about 5 cm above the bud grafting position after unbinding 15 days. After rootstock cutting, a large number of sprouting tillers will be pulled out at the base, which should be pulled out in time to avoid competing with scions for nutrients and affecting bud germination. At the same time, the nursery should be kept clean and free of weeds, and the supply of fertilizer and water should be sufficient. When the grafted seedlings grow to 50 cm high and the stem diameter is about 65438±00cm, they can be planted in the nursery.

2. High-yield cultivation techniques

Choose the soil with good irrigation and drainage and loose soil to build the garden, and plant it in spring, with the row spacing of 2×3 meters. About 0.3kg of lime, 30kg of garbage mixed fertilizer, 0.5kg of phosphate fertilizer, 0.5kg of soaked animal manure 10-15kg, 0.2kg of calcium magnesium phosphate10kg of compound fertilizer should be applied to the planting hole. After planting, young trees should be fertilized frequently and thinly. Generally, new shoots are fertilized twice for every 65,438+0 times of culture, and 65,438+0 times for bud stage and when the new shoots grow to 40cm. The fertilizer is mainly available nitrogen, and each plant can be applied with 2 5-5kg bran water and 0.3% urea, or 50g urea and 25g potassium chloride. Combined with soil improvement in winter, organic fertilizer 1 time and chicken manure 15kg were applied to each plant. Apply 0.5 kg of lime to each plant in winter and spring. Results Fertilization of trees is carried out around promoting the health of spring shoots and summer shoots, promoting the differentiation of flower buds of one or two fruits, setting strong fruits, improving soil and promoting root development. Attention should be paid to the application of organic fertilizer and lime, the ratio and adjustment of nitrogen, phosphorus and potassium fertilizer in each phenological period, and the coordination of late-acting fertilizer and quick-acting fertilizer, and fertilization should be carried out six times a year. AP annona is not afraid of drought and water accumulation, so attention should be paid to eliminating water accumulation in time in rainy season, which is prone to root rot; In case of drought and wrinkled leaves, water should be sprayed immediately, and soil moisture balance should be maintained during fruit setting to avoid cracking and falling off of fruits due to long-term drought and showers. AP annona should be cultivated in a planned way, and the pruning of young trees should focus on shaping, laying the foundation for early fruiting and high yield. The method of picking the heart and leaves should be adopted to promote branching and cultivate short, multi-branched and evenly distributed round crowns as soon as possible. Cut the top at the height of 40-50 cm in the trunk, and cut off 3-4 leaves in the middle and upper part of the trunk to promote the retention of 3-4 main branches. In the same way, 2-3 auxiliary main branches are promoted to be reserved on the main branches, and tertiary branches are promoted to be reserved on the auxiliary main branches, so that excessive and weak branches can be thinned out in time. Results Fruits were pruned 1 time every year after harvest, and the time was around mid-March. At this time, most of the bud eyes of deciduous branches began to sprout. The method is as follows: the big branches on the periphery of the crown are retracted and trimmed to the third or fourth branches, and after retraction, pile heads with a length of 20-30 cm are left, and the pile heads are required to be evenly distributed in the crown in an umbrella shape; Branches with a diameter greater than 0.5 cm in the crown cavity are generally reserved for retraction and pruning; The remaining weak branches and over-dense branches are sparse from the base. After re-cutting in spring, pay attention to timely thinning when the shoots grow to 5- 10 cm, and leave 2-3 evenly distributed new branches in each branch pile; When the fruiting branches or vegetative branches of new shoots are 30-40 cm long, they should be picked in time and pruned in summer according to the adjustment of production period. The method of removing the top and leaves can promote the growth and flowering of new shoots, thus adjusting the flowering period and fruit period. In Zhanjiang area, AP annona needs artificial pollination in April to strive for early fruit. At about 5 pm, taking other blooming flowers and applying pollen to the stigma of slightly or half-opened flowers with a soft brush can significantly increase the fruit setting, increase the number of fruit shapes and improve the fruit quality. In June, leaves should be cut and flowers should be promoted in various periods. According to the need, arranging flower promotion and pollination in different months can achieve the purpose of adjusting the fruiting period and extending the fruiting period from September to March of the following year.

The subtropical monsoon climate in the Pearl River Delta is also suitable for planting. Just follow the above method.

I hope the landlord can give Sakyamuni a bumper harvest! ~!
