What are the cultivation techniques for red-fleshed pomelo? A full analysis of the key planting points
Red-fleshed pomelo is an emerging variety of pomelo. Unlike white pomelo, red-fleshed pomelo contains a natural pigment that turns the entire flesh red. However, this pigment has certain health benefits for the human body and is beneficial for cardiovascular and cerebrovascular diseases as well as kidney diseases. Red-fleshed pomelo is now planted very widely in our country, so how should red-fleshed pomelo be cultivated? Below, the editor brings you the cultivation techniques for red-fleshed pomelo. Let's take a look!
1. Land preparation and orchard establishment
For red-fleshed pomelo cultivation, choose a leeward slope at lower altitude, with fertile, loose and deep soil, rich in humus, sufficient sunlight and normal drainage and irrigation. After choosing the land, prepare it and dig the holes, deeply plowing the soil to reduce pathogens in the soil. The area of each planting hole must be no less than 1 sq m. If it is flat land, make high beds of at least 35 cm, then dig the drainage ditches. Apply together with base fertilizer to ensure each planting hole has sufficient farmyard manure, promote nutrient absorption by young trees, ensure healthy growth and reduce the incidence of pests and diseases.
2. Nursery stock management
After digging the planting holes, control the planting density and plant at the right time. Usually red-fleshed pomelo is grafted first and then planted. About half a month after successful grafting, apply diluted manure water appropriately, once a month. Keep one strong new shoot on each pomelo tree, prune excess shoots and branches, and remove sprouts in time. After one month, untie promptly to promote healing of the wound at the grafted site. During the grafting period, water regularly to keep the soil moist and prevent poor growth of young trees caused by lack of water. When the stem of the new shoot has become about 16 cm and fully lignified, planting can begin.
3. Fertilizer and water management
The red-fleshed pomelo tree is large and bears a relatively high amount of flowers and fruit, so its nutrient demand is relatively great. Especially after red-fleshed pomelo enters the fruiting stage, vegetative and reproductive growth proceed together, and the entire fruiting period requires topdressing more than five times. For example, the first time is in mid-March, mainly with compound fertilizer and urea, to promote new shoot growth and increase the flowering rate. Then in mid-May, at the early fruit stage, apply fruit-strengthening fertilizer, mainly farmyard manure. Everyone should control the application of water and fertilizer according to the tree age, fruit load, soil and other conditions, so as to ensure the water and fertilizer needs of red-fleshed pomelo are met.
4. Pest and disease control
The prevention and control of pests and diseases in red-fleshed pomelo is very important, as pests and diseases can harm all organs of the red-fleshed pomelo tree. This seriously affects the flowering and fruiting rate of the pomelo tree, leads to low planting benefits, and causes reduced yield or even total crop loss. The common pests and diseases of red-fleshed pomelo are similar to those of ordinary white pomelo and other citrus fruit trees, and prevention is the main approach. Disinfect the orchard regularly, strengthen orchard management, observe the orchard frequently, and achieve early detection and early treatment of pests and diseases. Promote the growth of red-fleshed pomelo, strengthen its vigor, improve the stress resistance and immunity of the tree, and reduce the incidence of pests and diseases.
The above is a brief introduction to the cultivation techniques for red-fleshed pomelo. The growth cycle of red-fleshed pomelo is relatively long, and after it enters the fruiting stage, fruit can be harvested continuously for many years. However, everyone also needs to do a good job in orchard management. If you want to know exactly how to manage it, you can visit our website to view related past articles!
