Cultivation techniques of African Red Peach
"Red K", whose proper name is Roselle, is a plant of the genus hibiscus of Malvaceae, which is native to Africa. When "Hongtao K" was introduced and cultivated in China, the fruit yield per plant was as high as 5kg, the yield was more than 3000 kg per mu, and the output value per mu was more than 30 000 yuan. The fruit of "hearts K" is actually the calyx of rose eggplant. Calyx and bracteoles are used to make fruit pulp, beverage, extract pigment and so on. "Heart K" also has pharmacological functions such as lowering blood pressure, relieving thirst, promoting bile secretion, helping digestion and tonifying blood. After several years of cultivation practice, a set of effective cultivation techniques have been explored.
1. The garden chooses "Red Peach K" to be drought-resistant, not resistant to waterlogging and strong light-loving. It can be planted in mountains, hills and flat land. It is appropriate to choose the land with fertile soil, deep soil layer, loose texture, good drainage and plenty of sunshine.
two。 When planting "hearts K" seedlings, they must be planted in high and dry land. Before planting, 500 kg of mature organic fertilizer and 50 kg of compound fertilizer of nitrogen, phosphorus and potassium were applied per mu, and the soil was ploughed 30 cm deep. The land was planted after leveling, the row spacing was about 100 cm, and 667 plants were planted per mu. The planting time is suitable for late April to early May, and harvested and utilized in early November.
3. The root system of "Hongtao K" in fertilizer and water management is well developed and needs more nutrients. Fertilization should be based on organic fertilizer, and base fertilizer should account for 70% of the total annual fertilizer application, and topdressing should be mainly concentrated in three stages: first, after seedling planting, a return to green fertilizer based on nitrogen fertilizer should be applied once; second, after coring, it should be combined with re-application of nitrogen, phosphorus and potassium fertilizer as branch fertilizer; third, after bolting, a flower-promoting and fruit-protecting fertilizer based on phosphorus and potassium should be applied.
4. After 40 days of planting, when new shoots sprouted in the lower leaf axils, coring should be carried out to promote the branch growth of the lower nodes. When the branch is 10 cm long, it needs pruning in time to promote the development of flower branches and improve the rate of fruit preservation.
5. Timely harvest when the fruit ripening rate of "red peach K" fruit branch reaches 10%, it can be harvested in batches according to market demand, in order to improve fruit quality and plant fruit yield, and increase economic benefits.

The importance of jujube flower and fruit management
Jujube is a multi-flowered tree species, the differentiation of flowers is very large, but due to the influence of tree body and environmental conditions, the phenomenon of flower and fruit drop is very serious, and the fruit harvest rate is generally only 1-2% of the number of flower buds. There are many reasons for jujube flower and fruit drop. First of all, from the phenological phase of jujube, we can see that the bud stage of jujube is in the period of rapid growth and exuberant growth of jujube, in which phenology overlaps and nutrition competition is very fierce. When entering the early flowering stage, the jujube head is still in the exuberant growth stage, at this time the jujube hanging growth slows down. Several organs of jujube at the same time

Grading standard of jujube
Jujube fruit should be graded according to the quality and use of jujube to meet the needs of different uses. Different varieties have different standards. The general grading of jujube fruit can be divided into the following four grades. The weight of the super fruit is more than 20% larger than the average of the varieties, and the fruit is more uniform, the flesh of the fruit is thick, the surface is wrinkle-free, the color is pure and without color unevenness, there is no mildew rotten fruit, pulp rotten fruit, mechanical damage fruit and disease and insect fruit is less than 3%, and the moisture content is less than 25%. The first-class single fruit should reach the average fruit weight or slightly higher, and the fruit should be uniform.
