The results of several years' cultivation of Sakyamuni At present, the areas planted by Sakyamuni in China are mainly distributed in subtropical areas such as Zhejiang, Taiwan Province, Fujian, Guangdong, Guangxi and Yunnan. According to the introduction of fruit growers, the seedlings of Sakyamuni generally begin to bear fruit 2-3 years after planting, with the flowering period in May-June and the fruiting period in June-165438+ 10. In addition, Sakyamuni is a crop that can be harvested twice a year. After careful fertilization, pruning and flowering according to the season, huge and sweet fruits can be obtained. Only when Sakyamuni is just mature can we fully grasp the aroma and sweetness of Sakyamuni.
Of course, there are also many fruit farmers who report that some Sakyamuni fruit trees can only blossom but not bear fruit. Many of these situations are due to insufficient nutrient accumulation of fruit trees. This happened to saplings more than a year or two ago. When the trees are stronger and the flowers are more vigorous, it will be easy to bear fruit. There is another situation. Buds are bred, but saplings don't have enough nutrition, and they can't live without flowers, and they will soon wither. At this time, we should consider applying more organic fertilizer in the next spring to make the flowers bloom "more vigorously", and strengthen nutrition when flowering, which should be able to bear fruit.
Planting techniques and planting of Sakyamuni fruit
When planting annona squamosa, seedlings should be grafted with common annona squamosa as rootstock, and the best planting time is spring, especially before germination, with the highest survival rate. It can also be planted in the rainy season from June to July, but attention should be paid to drainage, and the roots of annona should avoid water accumulation. It is best to classify the seedlings when planting, and the seedlings transferred from other places should be soaked in water for 3-5 hours before planting. After that, put the seedlings into a hole with a depth of 20-30 cm, and the water-deficient mountain area can be appropriately deepened by 65,438+00 cm, so that the roots can be stretched and the seedlings can be stably supported while filling the soil. After planting, make a 1 tree tray around it, cover it with straw, and water the roots.
Abundant water
The fertilization principle of annona squamosa is scientific fertilization according to the tree size and different growth stages, mainly applying organic fertilizer, combining organic fertilizer with inorganic fertilizer, and gradually moving closer to green agriculture. Generally, 1 year is applied three times, and 1 time is carried out before and after pruning in winter, combined with deep tillage and garden cleaning. The application is mainly organic fertilizer, with deep digging and subsoiling, and full application. All organic fertilizers, phosphorus fertilizer 80 {BF} and nitrogen and potassium fertilizer 20 {BF} are applied throughout the year. The second time, in the young fruit period after flowering in Xia Guo (May-June), the annual total amount of nitrogen fertilizer 35 {BF}, phosphorus fertilizer 10 {BF} and potassium fertilizer 20 {BF} was applied; For the third time, in the winter young fruit period (September-June 65438+1October), the annual total amount of nitrogen fertilizer 35 {BF}, phosphorus fertilizer 10 {BF} and potassium fertilizer 35 {BF} was applied.
When applying, it should generally be dug and buried, and it is not appropriate to spread it. Trenching can be ditch-shaped, annular, semi-annular, radial, etc. Moreover, topdressing outside the root can be carried out according to the situation of the tree, and topdressing outside the root is also a limited way to supplement the nutrition of fruit trees. Topdressing outside the root can choose foliar fertilizers such as Plant Power 2003, Tianda 2 1 16 and potassium dihydrogen phosphate.
moisture
First of all, we should do a good job in field irrigation and drainage facilities to prevent droughts and floods. Irrigation period should be from germination to flowering, new shoot growth and young fruit expansion, rapid expansion, fruit picking and dormancy, and appropriate watering should be carried out according to the situation. The roots of annona squamosa are the most taboo to accumulate water, so drainage should be done well in rainy season to prevent water accumulation in orchards.
decrease
Annona should be pruned every year to maintain tree shape and promote flower bud differentiation. Pruning is generally done twice a year, in winter (1-March) 1 time, and in summer (June-September)1time. The purpose of pruning is to reduce the width of the tree, dwarf the plant and tidy up the tree. In winter, the whole plant should be defoliated artificially to promote flower bud differentiation and make the growth orderly. The fruit shape of annona squarrosa is generally controlled to be round or semi-round, and pruning is the key technology of off-season production.
choose
In production, the fruit is usually more than 250 grams when growing and more than 350 grams in winter. When the color of the peel has just turned green and there are no yellowish furrows near the pedicel, it can be harvested early. At about 22℃, it takes about 4 ~ 5 days to mature. In addition, the temperature during fruit ripening has an effect on ripening time and fruit quality. For example, when the temperature is between 25℃ and 35℃, the ripening time is short, the quality and flavor of the fruit are the best, and the flavor is rich, but the fruit will crack when it is soft ripe, and the cracked part is easy to be polluted; When the temperature is 18 ~ 20℃, the ripening time will be delayed by 1 ~ 2 days, and the fruit will not crack after soft ripening, with good quality and flavor, which is suitable for market sales. When the temperature is lower than 16℃, the fruit is difficult to mature and hard fruit will appear. Because the maturity of Sakyamuni varies greatly, it should be harvested in stages at a suitable cool temperature for storage and transportation.
